CCIE Qualification Test Sample Questions

The samples herein are intended to reflect the type of questions presented on the CCIE Qualification Test. In no way does this sample test reflect the diversity of the true test and Cisco assumes no responsibility for the performance of any person taking the CCIE Qualification Test subsequent to passing this sample.

Network Fundamentals:

1. Which layer<s> of the OSI Reference Model provide<s> for internetwork connectivity?

a. Data Linkb. Physicalc. Sessiond. Networke. Presentation

2. The DSAP and SSAP of an IEEE 802.2 header both are set to 'AA' hex to indicate:

a. There is routing information included in the packet.b. There is a SNAP header to follow.c. The packet suffered a collision.e . The Ethertype is Localtalk.e. The address was recognized and the frame accepted.

Bridge/Router Technology:

3. In a bridged, IEEE 802.5/Token Ring environment, which combination of bits indicate to the source that a packet has been forwarded across a bridging device?

a. A is 0, C is 0 and there is a RIF.b. A is 1, C is 0 and RII is 0.c. A is 0, C is 1 and there is no RIF.d. A is 1, C is 1 and RII is 1.e. The question is not applicable in a Token Ring environment.

4. Certain protocols such as SNA, Netbios and LAT are not routable and therefore must be bridged or encapsulated because:

a. Native IBM protocols do not conform to the OSI RM stack.b. SNA and Netbios cannot be routed but LAT can.c. They would be too CPU intensive.d. They only run in "batch mode" processes where routing is not an issue.e. These protocols have no explicit network address.

5. What is <are> the purpose<s> of the Spanning Tree Algorithm?

a. To keep routing updates from being transmitted onto the same port on which they were received.b. To prevent a "loop free" logical tree topology.c. To discover a "loop free" topology and provide, as possible, a path between every pair of LAN's.d. To provide a path between every LAN segment.e. To help ensure that messages will arrive over all possible paths.

6. Some disadvantages of bridging versus routing are: (more than one answer)

a. Bridges cannot provide any form of flow control.b. Bridges cannot provide congestive feedback information to end nodes.c. Bridges offer no form of filtering.d. Bridges are more difficult to administer/maintain than routers.e. Bridges create more overhead traffic than routers.

7. Split Horizon is primarily designed to: (more than one answer)

a. Prevent routing loops between adjacent routers.b. Ensure that information about a route is always sent back over the path on which it arrived.c. Functions to provide extra algorithm stability to "Hold Downs".d. Replace the "Poison Reverse Updates" algorithm.e. Ensure that hop counts are not exceeded.

Internet Protocols:

8. What is the maximum number of hosts that can be assigned to a class "C", non-subnetted network?

a. 1024b. 65025c. 254d. 16e. 48

9. The main difference between OSPF and RIP are:

a. Both are IGP's, but the RIP convergence time is much shorter than that of OSPF.b. RIP is a distance vector protocol whereas OSPF is a link state protocol.c. There is no difference between the two, other than RIP is used for IP and OSPF is used for OSI.d. OSPF allows for a lower hop count than RIP.e. RIP works better in large internetworks than OSPF.

10. Given the IP address of 193.243.12.43 and a subnet mask of 255.255.255.128, what is the subnet address?

a. 194.243.12.32b. 193.243.0.0c. 194.243.12.43

Network Scenarios

14. Refer to Exhibit A below. Router R1 and R2, T0 and T1 ports are configured, functionally, the same. The primary path between these router nodes will be:

a. If OSPF routing, the primary path is T0.b. If RIP routing, the primary path is T0.c. If IGRP routing, the primary path is T1.d. This is a misconfiguration and would cause beaconing on T0, therefore T1 is the primary.e. These rings would always be handled equally.

Surviving The Technical Job Interview

By: Chris Bryant, CCIE No. 12933 Routing & Switching

Ah, the technical interview.

Nothing like it.

Not only does it cause anxiety, but it causes anxiety for severaldifferent reasons.

How many people will be asking questions?

>From experience I can tell you there's nothing like walking into aroom and seeing nine people on the other side of the table.

Second, what will you be asked?

You'll sometimes hear people say the questions they were asked in atechnical interview were "easy", which translated means "theyasked me stuff I happened to know".

Sometimes you'll hear people say the questions were "hard", whichtranslated means "they asked me stuff I didn't know", or "theyasked me about stuff I've never even heard of".

Having been on both sides of the technical interview table, I'd liketo share some tips for those being interviewed.

In doing so, I'll share some of the more memorable interviews I'vebeen involved in.

No good interviewer expects you to know everything.

The problem is, you're not always going to be interviewed by someonewho's good at it.

Sometimes, the person who's giving you a technical interview wasasked to do it about ten minutes before you showed up.

Maybe they've never interviewed anyone before, or maybe they'rejust in a bad mood.

I've heard of technical interviewers where the interviewer derided ananswer, and that's totally unprofessional.

I've had many a job candidate give a bad answer to a question, and myonly response was silence followed by moving on to the next question.

If your interviewer mocks any of your answers, you didn't want towork there anyway.

None of us know everything.

If you're asked a question you just don't know the answer to,don't try to BS your way past it.

This is a good opportunity to tell the interviewer how you wouldresearch that particular question.

It's not about knowing everything, it's about being able to findout anything.

If your interviewer acts like he/she already dislikes you, that'sbecause they do.

I once worked with a technician who felt threatened by anyone whoapplied for a job there, but especially if the applicant had aprofessional certification and then had the nerve to know what theywere doing.

This technician participated in a group technical interview where theapplicant was an incredibly bright guy, and had a particular skill thatthe department really needed.

Problem was, the technician considered himself "the man" when itcame to that skill.

Recipe for disaster, right?

The applicant fielded four questions from the rest of us flawlessly,then faced this particular tech for a question.

The threatened tech had a list of questions for the interview, butdecided to ad lib.

Big mistake.

He asked a convoluted question that Rube Goldberg would have been proudof.

When he was done, the applicant answered:

"You can't do what you just described."

The tech started defending his question, and it became obvious that hehadn't been able to follow his own question!

The interview went into a bit of a meltdown from there.

Realize right now that there are some unprofessional people out theregiving technical interviews.

Be prepared for it, but remain professional yourself.

Be prepared for a practical technical interview.

The best technical interviewers find a way to get you in front of thetechnology you'll be working with.

A great way to quickly find out whether you know what you're talkingabout is to ask you to actually perform common and perhaps somenot-so-common tasks.

We can talk about technology and take all the computer-based exams wewant, but it all comes down to performance.

Be prepared to prove you belong on your interview day.

Be professional.

This covers a lot of ground, so let me make a quick list for you.

Show up 15 minutes early.

Nothing makes a technical interviewer more surly than waiting for theapplicant.

Dress for success.

The way you look when you walk into a room leads to yourinterviewer's first impression of you.

Don't chew gum during the interview.

Don't be arrogant.

Look, there's nothing wrong with having an ego and acting confident.

I do, and you should.

But don't come into the interview room acting like you're too goodto be there.

Finally, relax.

Easy to say, hard to do?

Not really.

Realize that the majority of interviewers you'll ever meet are goingto be professional about the entire thing.

The world's not going to end if you miss a question.

If you were not qualified on paper for the job, you wouldn't be inthere.

Do not look upon the interview as something negative.

Rather, look at it as an opportunity to prove you know what you'retalking about.

With the proper mental attitude, your technical interview will be aspringboard to the next step in your career!
