RE: ccie questions
Looking over my own printout, I see that there is no listing of the number of questions in each category. Just the percent correct. If I were to guess, based on my percentages and the fact that I passed with plenty of room to spare, I would guess that there are 1 or 2 multiservice questions, and 3 security questions tops.

Just a nit: it can't be an NDA violation to answer questions that others ask you, unless they're asking you "What's on the test?" The violation is in making the questions themselves public. **NOTE: New CCNA/CCDA List has been formed.

Well done, I totally agree... in the midst of you all playing at being CIA I notice you forget that Joel Studtmann actually replied to the question without mentioning the whole issue ONCE. His reponse was why I joined this group, not for crap about lawyers and the death penalty or whatever over dramatisation you have put on this matter. the guy was a jerk, fair enough but lets just drop the matter now. and if you didnt hear me the first time mr studtmann.

The one think working in Cisco'v favour is the fact that the lab is much more difficult than the written.

Re: CCIE Questions... Answer to Q3 ???
I know I'm being picky, but I find the question very confusing. My main gripe with it is that the frame sent from comp 1 is not the same frame as that which is re-transmitted on segment B due to the collision. i.e different CRC due to possibilities such as changes to TTL etc. So I would still like to offer the arument that Router B does not re-transmit the original frame from comp 1 on seg A but DOES re-transmit the frame that had a collision on seg B.

Re: CCIE Questions... Answer to Q3 ???
>>>SNIP Also, it's pretty clear that the question is about who retransmits the original frame, END SNIP I didn't think that the question was that clear, and produced my previous response from the argument that who transmits the next frame on segment B is independent of the conversation taking place i.e from comp 1 to 2. If we define "original" frame as the first frame transmitted from computer 1 then obviously this cannot be the same frame as that which would exist on segment B (different CRC), therefore the "original" frame could not be re-transmitted. If however, the "original" frame is the first frame from router B then the answer is more obvious and I agree.

RE: CCIE Questions...
John, I know exactly what the CCIE lab is. I sit for it in RTP October 30th and 31st. I also know how hard I've worked to get to this point and I don't want anyone devaluing my efforts. You seem to think it's ok to cheat or violate NDA's. You missed the idea entirely of my post - that it won't create more CCIE's, but that cheating on the written will allow more "non-qualified" people to sit for the lab, thereby creating an even greater backlog (currently at 4 months) of people waiting to get in. It does not in any way mean that more will pass, but it does mean that someone who is qualified may have to wait even longer, because someone who doesn't deserve a shat at the lab cheated their way ahead of those who put in the effort. As for John Galt, it's simply a tag line that goes with my sig. Who is John Galt? - is a rhetorical question from a book and was never intended to elicit an answer. Louie When I disagree with a rational man, I let reality be our final arbiter; If I am right, he will learn, If I am wrong, I will; one of us will win, but both of us will profit. - John Galt -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Kaberna Sent: Tuesday, September 19, 2000 4:53 PM To: Miller, Nathan (AZ15) Cc: [EMAIL PROTECTED] Subject: Re: CCIE Questions... No one is going to pass just because of a few questions they can memorize the answers to. I also don't know where you think we will be diluted with CCIE's because of this. The CCIE is a lab. I guess your referring to the paper test which, once again, doesn't mean squat. The pool is not going to be diluted because of NDA violations. Just like any other certification the combination of books geared directly for the exam and testing software that is very accurate will dilute the pool. The few people that violate the NDA will be of little consequence. As long as Cisco uses a large enough question database and changes the test frequently enough this won't be an issue.

The CCIE is a great certification. These people are simply trying to ensure that it retains its integrity. I look forward to taking a test that 70% of people fail the first time.

Re: CCIE Questions...
No one is going to pass just because of a few questions they can memorize the answers to. I also don't know where you think we will be diluted with CCIE's because of this. The CCIE is a lab. I guess your referring to the paper test which, once again, doesn't mean squat. The pool is not going to be diluted because of NDA violations. Just like any other certification the combination of books geared directly for the exam and testing software that is very accurate will dilute the pool. The few people that violate the NDA will be of little consequence. As long as Cisco uses a large enough question database and changes the test frequently enough this won't be an issue. You people love to beat a dead horse don't you.

Re: CCIE Questions...
Wrong again john some of us beleive in the certification process. We work hard to acheive the cert and don't want the process tainted more than it is. Seems to me the only people that don't care about the nda ARE THE PAPER TYPES and the ones who have no experience in networking but think they should get a job because they remembered some facts. Thats what we like about the ccie program, no pretenders just the lab and those standing. when i pass it will be because I qualified, me "Donald B Johnson Jr" not because I broke the nda. hey here is a good question Any CCIE that passed the lab without any hands on experience please tell us how you did it not what was on the test? And actually we did not initiate the certification process we inherited it. I think from the boy scouts, you know all those badges. god I loved that handbook.

RE: CCIE Questions...
John, Perhaps you have not grasped the idea that systematic violation of the NDAs devalues the certs that we are all (yourself included - I assume) working to earn. I for one, do not want the pool of CCNPs and CCIEs diluted by those who are incapable of passing the exams without memorizing the answers to a few specific questions. A significant part of the value of these certs comes from the perception (justified or not) that more than memorization is required to attain them.

RE: CCIE Questions...
So I gather that you feel it is perfectly OK, to divulge information that you have agreed not to disclose. If that is the case, don't agree to the NDA and see if Cisco is willing to let you test anyway. While I agree that the written tests have limited value, they are a measure of knowledge, in the case if the CCIE written, it is a qualifying exam for the lab. As such you need to demonstrate a level of knowledge that shows you have a credible chance of passing the lab. If you want people to pass this test by simply memorizing the questions, then the test serves no purpose. You can then look forward to a 2 year wait to get to the lab since thousands will take it without being qualified. It is a waste of their time as well as Cisco's. It also prevents those who are qualified from being able to obtain their CCIE in a timely manner. Is this the result you want to provide? Louie When I disagree with a rational man, I let reality be our final arbiter; If I am right, he will learn, If I am wrong, I will; one of us will win, but both of us will profit. - John Galt -Original Message- From: John Kaberna [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 19, 2000 3:10 PM To: [EMAIL PROTECTED]; 'Lori S Carter'; [EMAIL PROTECTED]; 'Bradley J.

Where do you think they come up with the questions that are exact or damn near the real test? So, unless you don't use testing software your just as guilty as the guy everyone is whining about. Besides, certifications don't mean squat if you can't back it up. I've seen plenty of CCNP's that don't know sh!t and they didn't violate the NDA. Written tests are all cheap if you ask me. The only cert that means a thing in my opinion is the CCIE lab.

RE: CCIE Questions...
John, the reason we despise those who violate the NDA is that they cheapen the Cisco certifications for all of those who worked, studied and followed the rules to get their certifications. Why would we let someone lessen the value of what we have achieved? We do not want Cisco's certifications to become worthless and everyone who violates the NDA, cheapens the value of our work and effort. Is that your goal? Louie "Thinking is man's only basic virtue, from which all others proceed.

The question doesn't assume that. Also, it's pretty clear that the question is about who retransmits the original frame, not who retransmits the frame that collided with it. The answer is obviously the router. This is fundamental Ethernet 101 stuff.

(I thought that was the latter as well... ) :) The switch retransmits when it senses a collision on a frame that it sent. It has to obey CSMA/CD. Just as with a router, an Ethernet port on a switch bounds the collision domain. If the originating host had to retransmit that would mean the collision domain spanned the switch. The switch would have to act like a hub and pass the jam signal back to the transmitter. This would wreak havoc on various Ethernet timing parameters, etc. You can't just memorize a rule that says the router doesn't retransmit, even though it is true for almost all cases. Perhaps a follow-up study question would be, in which other cases would the router retransmit?

Re: CCIE Questions... Answer to Q3 ???
I havn't read this thread so apologies if this has been done already. Computer 1 sends to Computer 2. Router B relays a valid frame to computer 2. Assume no other devices on Segment B for clarity, computer 2 must be transmitting a frame on this segment in order for the collision to occur. Therefore router B and computer 2 do a random back-off before attempting to re-transmit. So shouldn't the answer to which device re-transmits be "either" depending on which device can respond the fastest ? i.e Router B's frame is totally independent from Computer 2's frame.

Umm... How about this? "Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]" PS - these questions sure look like those on the exam, but they also look like questions I have seen in exam prep products and on exam prep web sites, etc. You might want to preface your snitching with the phrase "I think this person *may* have violated the NDA..." when you report it. These questions may be from memory of the exam or they may be from a study guide or other source. It may well be that the publisher of some 3rd party test prep product is the real violator of the NDA (if a violation has truly occurred).

Re: CCIE Questions...
Silly question... I was always under the impression that routers wouldn't retransmit. What about switches? Will they retransmit in the case of collisions, or do they leave it up to the hosts?

I think that it's a good thing in general to see questions here that are similar in style and difficulty to what we can expect on the test. However, whenever anyone posts such questions violations of the NDA come up. The best solution I can think of is for anyone posting such a question to state where it came from. "I made this up", "Homework assignment from a class", "Found in [name] study guide", etc. Also, it would help if people posting them were to explain what they think the answer is or what part of the question is stumping them. There are only so many ways of asking some questions, so it's not out of the question that something a person thinks up on their own or finds in a study guide would appear to be an NDA violation. -- Jay Hennigan - Network Administration - [EMAIL PROTECTED] NetLojix Communications, Inc.

Re: CCIE Questions...
I have a question about question 1. Some people answered Host A, other said the packet is lost. If the layer 4 protocol is UDP, it is lost, if it is TCP it will be resent. Would Cisco use the word "packet"to refer to a connection-oriented layer 4 protocol, TCP, and the word "datagram" to refer to UDP, connectionless?

Re: CCIE Questions...
Where did these questions come from? Please specify the source (book, etc.) so that we know we aren't disobeying the NDA and giving you answers from an actual test. These sure sound like questions from the CCIE written. Also, I think it would be best to limit each e-mail message to one topic. It makes discussions easier to follow. Despite all that, I can't resist giving you my answers! &;-) See below.

Retransmission is sent by: Host A retransmits the packet. The data-link layer protocols in use today on serial lines, including PPP, Frame Relay, and Cisco HDLC, detect errors but are not responsible for error correction or retransmission. >Question 2: >During the middle of a TCP conversion across a routed backbone, the network >receives a voltage spike and several of the packets are damaged.

Router B senses the collision and retransmits at the MAC layer. The MAC address is Router B's Ethernet address. >Question 4: >When computer A sends a frame to computer B across many routers, how will >the source and destination layer 3 addresses change? How will the source and >destination layer 2 addresses change? Layer 3 addresses won't change (unless you have NAT or tunnelling or something else bizarre.) The Layer 2 addresses change each time a router re-encapsulates the packet in a data-link-layer header than includes layer-2 addresses.

Re: CCIE Questions...
Definately a good point, although RIP uses UDP port 520 and EIGRP uses multicast port 224.0.0.10. Multicast packets are baesd on UDP. I wasn't thinking ICMP and IGMP...

RE: CCIE Questions...
Actually, I never specified that the packet in questioin number 1 had to be UDP. Question 1 only specifies that the routers are routing IP. It could be an ICMP, IGMP, RIP, EIGRP, etc... packet. Not all IP packets use a transport protocol. Granted, 99% of user traffic does, but the question doesn't specify. I'm just not completely familiar with all of the possible data-link protocols available over a serial link, and which ones (if any) would detect the bad packet and have the last station retransmit. I think x25 would, as its overengineered for providing error-checking, and think PPP might.

RE: CCIE Questions...
Replying out of order: Question 2) Packet is damaged and has a bad CRC at the datalink layer, so is dropped by next switch or router or end PC that verifies the CRC. (A hub wouldn't notice). Retransmission is sent from the original source (IP host) after not receiving an acknowledgement for that packet from the destination. Question 3) Collison occurs, and is detected by Router B. Router B then retransmits the packet. Source MAC address will be Router B, as the router changes the source MAC to itself and the destination to the next hop. (In this case, computer 2) Question 4) Layer 3 sources and destinations will not change. (Ignoring issues such as NAT here, for simplicity). Layer 2 MAC addresses will change whenever the packet crosses a layer-3 device, as the router removes the old datalink information, examines the layer 3 information, and repackages the packet for the next hop device, changing the destination MAC address to the next hop and the source MAC address to itself. Back to Question 1) My first answer is that the packet is simply lost. The protocol is simply IP, which provides best-effort delivery, and wouldn't be retransmitted by the host (assuming it's not a TCP packet). I'm not completely familiar with all types of serial line encapsulations, but I believe it would be retransmitted by the router if it was over an x25 link. Possibly PPP as well.
