| General Questions |
| Q. |
What is vLab technology? |
| A. |
vLab technology is real, hands-on experience with real routers or real computers. It is not a simulation or a computer-based training program. Each lab provides an experience similar to working on a production network at a company. Each Cisco lab is designed to enable you to practice a certain aspect of working with Cisco equipment (in most situations you wouldn't be sitting in the server closet with the routers, you'd be telnetting to Timbuktu and configuring the routers remotely). Each Microsoft lab is designed to enable you to practice a certain aspect of designing, configuring, or administering Windows 2000 systems, as if you were sitting at the computer console. |
|
| Q. |
What's the benefit for me to sign up for these 'self-study' labs? |
| A. |
The vLab system modules are flexible and help to extend and reinforce your technical experience. Students can select modules by vendor or technology that are targeted specifically to their needs without sitting through an entire day or week of training. The convenient combination of theoretical content and hands-on lab time allows students to work at their own pace, on their own schedule. And it's a fun way to learn. |
|
| Q. |
When working on a lab, if something comes up and I cannot stay online the entire time to complete the lab, can the unused time be rescheduled? |
| A. |
Unfortunately, unused lab time cannot be saved to be used later. Since you are telnetting to actual routers and switches, or loading software on real computer systems, we have to limit access to the time the lab is taken. |
|
| Q. |
How do I schedule a lab? |
| A. |
In your lab folder, click on the Schedule button to schedule the lab. In the Scheduling function, specify the time you'd like to take the lab. If that time is not available, the Scheduler will identify the nearest times before and after the requested time. (Note: all times are displayed in the time zone configured for your PC). |
|
| Q. |
How do I take the labs? |
| A. |
Using the vLab system:
- Click the vLab Exercises link on My Courses or the vLab Locker link on My Training.
- In your locker, you will see your available labs.
- Click on the lab you want to take.
- In the lab folder, select "Preview Scenario."
- Read the scenario carefully. We generally recommend you print it for your reference.
- Take the time to plan your solution. Read the appropriate chapters in your textbooks. Include commands you'll use, and look up areas in which you have questions.
- When you are fully prepared, log back in and select the lab.
- In the lab folder, either click on the start button to take the lab now (assuming lab resources are available) or schedule it for a convenient time and return at that time to take the lab.
- As soon as you start the lab, print out the "Suggested Approach" and "Sample Solution." The "Suggested Approach" is a high level overview on how to approach the lab. The "Sample Solution" has the detailed steps, hints, and explanations if you get stuck.
- Have Fun!

| Q. |
How do I access the devices in a Cisco lab? |
| A. |
After the lab loads and the network diagram appears in your browser window, clicking on each of the devices on the diagram will initiate a telnet window for you. Note that it will take some time (up to a minute, depending on network access speed) for the applet that provides the telnet window to load the first time. Follow the lab "Scenario" for instructions on whether or not passwords are required and specific password identification. |
|
| Q. |
How do I access the devices in a Microsoft lab? |
| A. |
After the lab loads and the network diagram appears in your browser window, clicking on each of the devices on the diagram will open a new browser window that shows you the console for the corresponding computer. Note that it will take some time (up to a minute, depending on network access speed) for the applet that provides the vLab system interface to load the first time. Follow the lab "Scenario" for instructions on how to log on to the systems. |
|
| Q. |
How do I know if I've been successful in meeting all the objectives of the lab? Is there some type of confirmation or pass/fail grading? |
| A. |
The best way to judge your performance is to look at the sample solution and compare your steps with those recommended. For Cisco labs, you can also do a "show run" on the devices and compare the output with that shown in the Check Results section. For Microsoft labs, you can perform the steps suggested in the Check Results section. |
|
| Q. |
Are there theory only labs, or do all modules include practice time on real equipment? |
| A. |
All lab modules include practice time on real computers, routers, and switches. We also offer "build-your-own" Cisco labs that allow for the ability to reserve unstructured experimentation time on that equipment. |
|
| Q. |
If I finish a lab quickly, what are my options? |
| A. |
You are welcome to continue working with the equipment group and try additional configurations. The complete lab experience includes web-based training content, and online access to equipment. No credit is available for unused time. |
|
| Q. |
Why are some labs more expensive than others? |
| A. |
Pricing is sensitive to the complexity of the equipment involved and to the amount of time the equipment is in use. Most Cisco labs deploy three devices and have a 55-minute completion time. Some Cisco labs deploy six routers, have a longer time limit, and have an additional premium applied. Microsoft labs can employ 1, 2, 3 or 4 computers and require anywhere from 40 to 80 minutes of lab time. |
|
| Q. |
Where does the lab content come from? |
| A. |
We employ world-renowned network experts to develop the course content. All of our authors are vendor certified as instructors and/or consultants in their fields. Our training modules are based on real world applications and issues. The authors develop the lab modules based on their extensive experience training and consulting as information technology specialists, and their expertise in solving problems and situations they encounter. |
|
| Q. |
Are the labs a replacement for off-site training or computer based training? |
| A. |
No they are not. The vLab system is a self-study learning environment that seeks to augment formal training classes and on-the-job learning with structured modules providing targeted problem-solving experiences. Unlike computer based training, this learning experience incorporates theoretical concepts with testing and configuration on real equipment. |
|
| Q. |
Can I get help with the labs if I get stuck? |
| A. |
Yes. Online hints and help are part of each learning module. You can follow the on-screen guided instructions in the "Sample Solution." As needed, you can follow links to background material explaining the principles involved, as well as a step-by-step guide that will show you how to solve the problem. |
|
| Q. |
What if I start a lab and it is too simple or too hard - can I skip to another lab? |
| A. |
We try to provide enough material in the course descriptions and objectives so that you will select the courses appropriately. It is a difficult process to refine since we offer our service to the full range of experience levels. If you make a mistake, or we just weren't clear enough, we will provide an appropriate replacement lab. |
|
| Q. |
I signed up for a lab, but I did not start the lab yet. I am not sure that I am ready for this lab yet and would like to try a more basic lab first. Can I change to something for beginners? |
| A. |
Contact Technical Support at (800) 250-5013 (option #1) and we can help change the lab for you. |
|
| Q. |
Will I break anything if I fool around with the equipment after I finish my lab? |
| A. |
No, the vLab system modules support the training of many levels of students. There are reset procedures to reinitialize the configurations that are required to begin each lab. Feel free to experiment. |
|
| Q. |
What is the benefit of taking a vLab system self-study course? |
| A. |
The vLab system modules are flexible and help to extend and reinforce your technical experience. Students can select modules by vendor or technology that are targeted specifically to their needs without sitting through an entire day or week of training. The convenient combination of theoretical content and hands-on lab time allows students to work at their own pace, and on their own schedule. And it's a fun way to learn. |
|
| vLab Client OS and Equipment Questions |
|
| Q. |
I want to know if a vLab exercise can be done from a Sun Workstation or if it's only a Windows-based application. |
| A. |
vLab exercises can be taken anywhere that the requirements listed in the system requirements are met. |
|
| Q. |
I'm sure you don't "support" Linux, but is there any reason why the vLab system sessions would not work with Linux? |
| A. |
There is no OS requirement for the vLab system. As long as you are running one of the accepted browsers it should work. Check the System Requirements page for further details. |
|
| Q. |
My AOL browser doesn't work with your system. I can't access a telnet session for my Cisco lab. What do I need to know? |
| A. |
AOL uses a modified version of Internet Explorer in addition to restricting services on various ports. You need to minimize the AOL application after you have logged in. Then run your Microsoft Internet Explorer or Netscape Navigator browser to access our site and take a lab. This would also hold true for @Home and RoadRunner or any other ISP that uses a customized browser. |
|
| Q. |
What resources does my computer need to use vLab technology? |
| A. |
The web-based content can be viewed with current versions of Netscape and Internet Explorer browsers. Access to the Cisco equipment groups requires a Java-enabled browser or a standard TCP/IP stack supporting telnet, FTP, and PING. Each student is responsible for configuring and maintaining their computer, obtaining an internet connection with a frames-based browser, and implementing any required software for their computer. |
|
| Q. |
Can I take vLab system training if I have cable modem service? Can I use the browser my cable modem service provider offers? |
| A. |
If the service provides a standard Netscape or Internet Explorer browser, yes. If it provides another browser, that browser may not work. In that case, download and run the Internet Explorer or Netscape browser to access our site and take a lab. |
|
| Lab Procedures for Cisco Labs |
|
| Q. |
I want to preserve what I've done so far in a Cisco lab...how do I save my configurations? |
| A. |
There are three buttons that are important for you to know: "Cycle Break", "Save", and "Reset". "Save" allows you to save the current configurations in your lab and "Load" will return the devices to that saved state. Maybe you're unsure of the next configuration command and you want to be able to return to a safety point or, maybe, you want to try something outside the parameters of the lab and you will want to get back to where you left. If you "Save" the device configuration, perform the experimental step, and find that step to be unworkable, you can "Cycle Break" (if communications are completely lost) or "Reset" and then "Load" your saved configuration. |
|
| Q. |
If I start a Cisco lab and can't finish it in the scheduled time frame, can I continue? |
| A. |
Yes. Equipment configurations are automatically saved at the end of a session unless you choose to manually save one or more device configurations during the course of your lab. If you do perform a "Save" during a lab, you will need to manually "Save" all your configurations before the lab ends. At the expiration of the lab time, your manual "Save" or the automatic "Save" configurations can be archived from your locker. You can then purchase the lab again, giving yourself another hour of lab time. When you take the "new" lab, you can retrieve your saved configurations and load them into the corresponding devices in the "new" lab. In this way, you are able to continue the lab from the point at which you ran out of time. |
|
| Q. |
How do I 'Archive' my Cisco lab? |
| A. |
If you run a lab and never initiate any "Saves" during the course of that lab, the system will automatically save your configurations when the lab is complete or runs out of time. At this point, the lab moves from the "Purchased" section of your locker to the "Completed" section. Now, one of the options associated with the lab is "Archive". This moves the lab from "Completed" to "Archived". |
|
| Q. |
What are the Cisco 'Lab Buttons' and what do they do? |
| A. |
There are three buttons that are important for you to know: "Cycle Break", "Save", and "Reset":
Cycle Break
"Cycle Break" is the button of last resort. Should you enter a configuration which prevents you from communicating with the device(s), "Cycle Break" resets the device(s) with no configuration. You can then select "Reset" to restore the original lab configs or select "Load", if you have saved configurations you would like to restore. Performing a "Cycle Break/Reset" or "Load" will break communication with that device and you will have to re-initiate a telnet session by selecting the device on the lab diagram. WARNING: do not select "Cycle Break" and then "Save".
Reset
"Reset" allows you to reset one or more of the devices in your lab. You may have inadvertently or experimentally changed a configuration setting that caused the device(s) to hang. "Reset" allows you to get back to the starting configuration of the lab. If you do perform a reset, you will lose communication with that device and will have to re-initiate a telnet session by selecting the device on the lab diagram.
Save
"Save" allows you to save the current configurations in your lab and "Load" will return the devices to that saved state. Maybe you're unsure of the next configuration command and you want to be able to return to a safety point or, maybe, you want to try something outside the parameters of the lab and you will want to get back to where you left. If you "Save" the device configuration, perform the experimental step, and find that step to be unworkable, you can "Cycle Break" (if communications are completely lost) or "Reset" and then "Load" your saved configuration.
Note : Selecting "Cycle Break" and "Save" in sequence will cause an error condition that will disable the equipment, and you will not be able to continue with your lab. Should this happen, contact Customer Support to reschedule your lab. |
|
| Q. |
What interfaces are available? |
| A. |
The router and switch interfaces vary depending on the specific module on which you are working. Various labs support configuring serial, Ethernet, Frame-Relay, ISDN, switch, and voice interfaces. |
|
| Q. |
What is the lab configuration? |
| A. |
The term "lab configuration" differs from the router configurations - and is another common term. Router configurations are data resident inside the router that contains addressing and parameter information. The term "lab configuration" simply refers to the way the routers in a lab are interconnected. The lab configuration will vary depending on the specific lab you are working on. The routing labs will support one or more suites of three routers, depending on the specific exercise, as well as the equipment needed to establish frame relay and ISDN. The Switch Labs and the Voice-Over-Layer2 Labs, of course, contain the required gear to provide a basic environment. |
|
| Q. |
Can the lab configuration be changed? |
| A. |
Yes. When you take a lab, you are given exclusive access to an equipment group assigned by that lab. Once you are in "Config" mode, you can do whatever you'd like, based on the connectivity available for that equipment group. |
|
| Q. |
When starting a lab, what do I need to do to acquire the configurations that apply to my lab? When I begin, there are no configurations. Am I leaving off a step? |
| A. |
The starting configurations will be loaded on all the equipment when you start the lab. That is why a takes a few minutes to load the lab before you can start your changes. Depending on the lab you take, some labs will have many pre-configurations and others will have hardly any. Please consult the preview scenario for your starting conditions. You can also check the sample solution for hints on how to proceed. |
|
| Q. |
What is Cisco pre-work, and why do you suggest I do it before starting the lab session? |
| A. |
After registering for the lab and signing up for an on-line session, you will be able to pull down the pre-work material. Review of the pre-work material before your on-line session will make your entire learning experience more productive. When your assigned time slot is active, you will configure and monitor the actual routers and switches in equipment group. |
|
| Q. |
How long after completing the labs will the saved configs and other information that is archived be available to me? |
| A. |
Archived materials stay in the locker indefinitely. However, if you are planning on saving them long term please copy them to another location. |
|
| Lab procedures for Microsoft labs |
|
| Q. |
If I start a Microsoft lab and can't finish it in the scheduled time frame, can I continue? |
| A. |
Unfortunately not. The computers in the vLab system modules are loaded with a completely fresh version of the operating system, configured with the appropriate settings for each individual lab, each time you start a lab. |
|
| Q. |
What are the 'Lab Buttons' and what do they do? |
| A. |
The Select All button selects all of the devices to be included in the action that the user will next request.
The Clear All button will un-check all devices that have been previously selected.
The Reload button will reload the device or devices that have been selected with the lab's starting configuration.
The Reboot button will perform a power cycle on the device or devices that have been selected.
|
|
| Q. |
What operating systems are available? |
| A. |
You will be working with Windows 2000 Server and Windows 2000 Professional computers. Each lab involves a different combination of computer types and network configurations. |
|
| Q. |
How do I log on or log off to the vLab system computers? |
| A. |
Normally, you initiate a Windows 2000 logon by pressing the Ctrl+Alt+Del key combination on your keyboard. If you do this during the vLab exercise, your own local system will intercept the keystrokes and respond. To work around this, you can click the "Send Ctrl+Alt+Del" button at the top of each vLab browser window and then follow normal Windows 2000 logon procedures. See the instructions in your individual lab for user logon names and passwords. |
|
| Q. |
I need administrative access to my vLab system computers. How do I do that? |
| A. |
You have full administrative access to all your vLab system computers at all times. You can log on to any computer or domain as the Administrator user. The password for this user is always "password". |
|
| Q. |
Why does each vLab system computer have two network connections? |
| A. |
One connection is an internal interface to the vLab system virtual LAN, and one is an external Web connection to support the browser-based vLab system interface. The Local Area Connection object connects to the virtual LAN, and the Do Not Touch object connects to the Internet. |
|
| Q. |
Can I reconfigure the network connections? |
| A. |
Feel free to reconfigure the Local Area Connection object as necessary. Don't reconfigure the connection labeled Do Not Touch. If you do, you will lose your Internet connection to the vLab system computer, and you will have to reboot the machine to continue working. Also, don't make any configuration changes that affect both connections; for example, don't remove the Client for Microsoft Networks from either connection. |
|
| Q. |
Why am I getting a Found New Hardware message? Do I really need to reboot? |
| A. |
No, you do not need to reboot your vLab system computers when you see the Found New Hardware message. The hardware variations between individual vLab system computers are extremely minor. Your vLab system will key correctly without rebooting. |
|
| Q. |
What if I need to restart my vLab system - for example, if I add a network service, or run a domain controller promotion? |
| A. |
You can restart the system from the computer console or your lab Web page. The computer will reboot, and while it does, your connection will be inactive and your browser window will be blank. To reconnect to the system once it comes back on line, return to the console where you started the lab and click on the appropriate device link. Be very careful, however, always to restart the system and never to do a complete shut down. If the system is shut down completely, there is no way for you to re-connect to it remotely via the Web. |
|
| Q. |
Why did my browser window go blank? Why is my connection to the vLab system computer unavailable? |
| A. |
The remote computer is probably rebooting. You'll be able to reconnect once it comes back on line. |
|
| Q. |
How can I reconnect to a computer once it's rebooted? |
| A. |
Return to the console page and click on the appropriate device link. |
|
| Q. |
My lab was supposed to be ready at a given time, and it's not. What gives? |
| A. |
Although the lab load process generally completes within the scheduled time, at times there will be slight system delays. Your lab will be available shortly. If your lab loads so slowly that you feel you do not have time to complete the lab activities, call technical support at (800) 250-5013 (option #1). |
|
| Q. |
Why does it take so long for reboots? |
| A. |
There are various scripts and applets that need to run at boot time to create the vLab system environment. This might cause a slight perceived delay in the normal system boot cycle. |
|
| Q. |
When can I use keyboard shortcuts, and when do I need to use the mouse? |
| A. |
It is always safe to use the mouse to interact with the remote vLab system console. In many cases, you can also use keyboard alternatives, such as pressing [Esc] to select the Cancel button, or pressing [Enter] to choose OK. However, you want to avoid keystrokes that might be intercepted by the active application on your local system. For example, [Alt] = [F4] will close your local browser window, not the open application on the remote vLab system. If this happens to you, no problem; just go back to the Console Page and click the appropriate device link to re-connect. Your system will still be running, exactly the way you left it. |
|
| Q. |
What percentage of Microsoft Certified Professional test objectives are covered in each lab and each lab pack? |
| A. |
Each vLab exercise contains activities that are practically useful for Windows 2000 system administrators as well as that support test preparation activities for MCP candidates. However, there is no base percentage of test objectives covered in each lab or lab pack. Objectives can range in scope from very minute to very broad, and don't necessarily relate directly to a given amount of lab activity. Also, some test objectives are purely theoretical and do not lend themselves well to the hands-on vLab system learning model. Before you schedule your certification test, you should definitely plan to review the entire test preparation document for your test and perform any necessary individual study and preparation. For more information on MCP testing, see the Microsoft Certification web site at http://www.microsoft.com/trainingandservices . |

|
| Q. |
If I purchase the ICNDe E-Learning Edition, which vLab system "track" should I select? |
| A. |
The "ICND Track" pack. |
|
| Q. |
What can help me understand binary numbers? |
| A. |
Binary works on powers of 2, each additional bit doubles the possible numbers.
One good trick is to memorize the following binary table:
128 = 1000 0000 +64 +0100 0000 192 = 1100 0000 (note that 0100 0000 equals 64 in decimal) +32 +0010 0000 224 = 1110 0000 (note that 0010 0000 equals 32 in decimal) +16 +0001 0000 240 = 1111 0000 (note that 0001 0000 equals 16 in decimal) +8 +0000 1000 248 = 1111 1000 (note that 0000 1000 equals 8 in decimal) +4 +0000 0100 252 = 1111 1100 (note that 0000 0100 equals 4 in decimal) +2 +0000 0010 254 = 1111 1110 (note that 0000 0010 equals 2 in decimal) +1 +0000 0001 255 = 1111 1111 (note that 0000 0001 equals 1 in decimal) |
|
| Q. |
How do I run a Trace Route? |
| A. |
Select START in the lower left of the desktop. Select RUN, then type COMMAND to open a DOS prompt. At the prompt type TRACERT (space) then paste in the URL you are trying to reach. EXP: tracert http://www.elementk.com/ Press enter.

| CCNA Questions |
|
| CIR and Traffic Shaping |
|
| Q. |
Why must I use CIR to configure sub-interfaces' bandwidth? Also, how do I use command 'traffic-shaping' to make traffic perfect? |
| A. |
The "bandwidth" command is independent of the CIR and statically sets the router's perception of the speed of the link. The actual speed being dependent on the clock rate normally provided by the carrier. The bandwidth is used by the router to calculate the speed and delay of the link for routing purposes and for load thresholds in bandwidth aggregation of multiple links. The CIR is the bandwidth that you purchase from the Frame Relay service provider, normally on a PVC-by-PVC basis. This is the bit rate that you assume will be the normal transmission speed of the PVC. You also purchase the ability to send a certain amount of bits in excess of the CIR. If you exceed the bit rate you have purchased from the service provider has three options, ignore your excess and transmit the data, charge you for the excess traffic, or discard the traffic. What happens depends on the carrier and what your contract specifies (and, in some cases, how much bandwidth the carrier has). You cannot use traffic shaping to make "make traffic perfect." Traffic shaping permits you to allocate the appropriate bandwidth to multiple PVC's on a single physical link. This is normally done to handle situations where you are transmitting bits in excess of the permitted rate (burst of committed) or to control the allocation of available bandwidth to certain types of traffic. "Perfect traffic" is not a commonly defined term. If you mean not dropping any frames, you must purchase sufficient bandwidth and insure that the carrier, under the conditions of your contract, will not drop frames. If you do not have sufficient bandwidth no amount of traffic shaping will make traffic perfect. |
|
| Error Messages |
|
| Q. |
What does the error message '%DEC21140-5-LATECOLL:Unit 0, late collision error' on frame relay PVC mean? |
| A. |
The error message you describe is displayed for Ethernet interfaces. It means that two (or more) network stations attempted to transmit data at the same time. In moderate numbers, collisions are a normal part of Ethernet operation. The stations will automatically recover from the error. Collisions are normally caused by failures in wiring, network cards, and improper cable implementation. |
|
| Q. |
Can I have non-contiguous subnets? |
| A. |
More advanced routing protocols permit non-contiguous subnets. You must ensure, however, the routing protocol advertises all appropriate subnets. This may involve turning off route summarization. |
|
| Q. |
Can I use an IP subnet of zero? |
| A. |
Subnetting by using all zeros is illegal and highly discouraged. |
|
| CCNP 2.0 Courses |
|
| Q. |
Are you going to update your courses to include the new requirements for CCNP 2.0? If so, when? |
| A. |
CCNP 2.0 is the cert based on BSCN, BCMSN, and BCRAN, which we now have available in our catalog. |
|
| Q. |
Do the labs correspond with Cisco's Career Certification program? |
| A. |
Our vLab system is Cisco's designated Remote Lab Provider for their E-Learning product line. The vLab system is the perfect compliment to the existing training channels such as Instructor Led Training (ILT) and Computer Based Training (CBT). The vLab system is a modular, "self-study" learning environment that is well suited to extend or further develop the materials covered in the Career Certification program. |

| CCNP |
|
| Q. |
How can I use the command "ip nat pool" and "ip nat outside" on my three Cisco 2522s (its IOS version is 11.3)? |
| A. |
Correct operation of NAT requires no more than one connecting point between inside and outside networks. You will have to further describe your network and where you will be configuring NAT server more fully before I can comment on that part of the question. The "ip nat pool" command is used to define a group of address to which you translate. This is normally your official address on the internet. In the "ip nat" command you specify an access list number that defines address that are private and that you want to translate to an address in the defined NAT pool. For a more extensive explanation reference the Cisco CD or http://www.cisco.com/. Both sources have detailed descriptions and diagrams. |

| Q. |
How do I use ISDN Dial Backup for Frame-relay PVC on Cisco 4700(it has a cE1/PRI card)? |
| A. |
ISDN E-1 PRI backup of E-1 circuits on a Cisco 4700 is not part of the virtual lab's offered online at this time. PRI's can be used for dial-backup. If you are backing up multiple Frame Relay PVC's you will need to configure a virtual interface for each PVC in the form of a dialer profile. There are two methods of implementing dial-backup, Cisco proprietary using the "backup interface" command and floating static routes. There are examples of each technique on CCD and CCO. Cisco training partners offer information on dial backup in the CMTD training class. There is a third backup technique called "dialer watch" that is available as of IOS Version 11.3. |
