    What's the limit of the Extra-configuration in the lab???

    Nersas Marin - CCIE #48922

      Hello, this discussion is about the extra-configuration that you are allowed to do in the lab exam without losing any point.

       

      I am pretty sure that facing different tickets in the labs, you realiced that multiple solution can solve the issue as well as some extra command that you can apply to make sure that you get the points. I attach a few examples:

       

      IPv6: When you configure IPv6 in FR, sometime you have to map IPv6 address and link-local. Depending of the problem you may need or may don't need to put the "BROADCAST" word at the end of the statement. What if you always include that word? So that, you will always be right. Would be the ticket correct??

       

      Services Logging: If you are asked to configure multiple traps and some of them have dependences, you may configure many of them that probably are not be asked. Would the ticket correct??

       

      Services Views & Menu: Configuring this kind of services you have to introduce many commands that can be tricky. So that, you can over configure many commands that are not probably needed. Would be the ticket correct?

       

      Security Reflexing ACL: This configuration can be also over configured in order to make sure that you don't mess up your entire network blocking address. Would be the ticket correct?

       

      These are just a few examples just in order you get the points what I mean. I am thinking that checking the lab exam you always will try to make sure that you don't miss any point, and I am not sure about what would be the limit of the extra configurations.

       

      What do you think??

          Hi Nersas,

           

          Just a point of view of a ccie candidate, but I think you grab the rope by the wrong manner and you loose some fingers at the end.

           

          Let me explain, i never attempt the lab again but if you read on the subject on the cisco site, on the community or watch some Cisco video about the CCIE, you will find a very important note:

           

          " You must read the full exam first to understand and assess it "

           

          Certainly you have already watch this video on youtube but in case you don't it's a Cisco official video:

          "The CCIE lab: What to expect on lab day."

           

          Even if, effectively, it always more than one way to do it, like some perl scripters often say.

          I hope Cisco drive us to do such or such thing, and if it's not stricly asked to do very specific tuning/configuration in a question, we all have some lattitude !

           

          I hope i'm right, i'm prepared like that and it added me some peace of mind. I will see if i'm right very soon

           

          Good luck in you study,

          Stephane

            In my opinion there is very little room for original solutions to the problems in the lab.  They have a solution in mind and if you read the restrictions carefully it will take you down the path of the correct solution.

                 On the lab exam they use an script that looks for some commands, look for the configuration they want to see, so if you have extra configuration will not match these scripts. But of course, you should match the configuration they are looking for. If you give other answer or solution to the questions there will be a mismatch, that will be revised by the proctor. Maybe if he likes the new solution, will give the points.

               

                 They dont check every router configuration, this is done automatically. So extra configuration will be useless to pass the exam. Also, you are going to expend your time in something that will give no points, and one of the exam goals is the time management. You cant spend your time that way.

               

                And at each question, you can spend only the time needed to answer, if you dont know how to get the solution or it dont work and you dont know why, give up and go for the next question. You have to save your time for the answer you know.

                I DO NOT recommend adding extra configuration at all. Some people say it's OK, and some say it is NOT. I say do the right thing and you don't need to worry about it.

                 

                As consultants, how many times we see 1000 lines of ACL (A little exaggeration) on the client router/s, and you try to figure out what these guys are trying to do, and right in the middle of this 1000 line ACL you see "Permit IP Any Any"; I guess he/she configured this just in case.

                 

                As CCIEs we should not use any command/s from the “just in case” section of the command reference.

                 

                So do the right thing and NEVER include one and even one extra option if it should not be there.

                  I'm totally agree but i think Nersas speak about extra-configuration that doesn't necesserally has any meaning or significance, but we had it without notice that and the result of the lab is what Cisco Proctors and BotCorrector expected plus anything else.

                   

                  Extremely hard to explain with english words, perhaps with some simple math:

                    If the result expected of the following equation is 2 = 1 + 1

                    And if in the lab we say: 2 + 0 = 1 + 1

                    Is the ' 0 ' useless extra-configuration that we use permit to loose points ? the result is here, with some time-lost and greedy configuration lines ... i really hope not

                   

                  Wow what a great idea, i don't know the "just in case" section in the Command Reference, is it hidden ?! We must send an RFE to Cisco for that for the real life

                      Hello Stephane, thank for your reply and the video link. I already checked it out long time ago and It's a good idea to review again. Also, VERY GOOD point your math example. You tottaly got what I meant opening this discussion. Good luck with ur practices.

                       

                      Hello Piper and Alejandro, I am agree with you and Alejandro about saving time and answer just the right commands that are expected, but let me point out something.

                      I think that you don't have too much answer variations on the lab exam tickets, but you both probably be agree with me that you can apply BGP filters/AS-Paths with different options, you can apply filters about IGP with route-maps, distribute-list, etc.... so that I still thing about different options per ticket. Although, I am agree with you about some tickets that there is nothing to choose, either you pick up and write the right commands or..... bye bye

                      I also think about time saving, but I guess that VERYBODY have been facing the 4 or 5 point ticket where you are veryyyy close to get it but still missing one small thing. My mind is telling me "not leave it!!! you are close to get it or you will lose all points" (Like the IPv6 questions that take u a long time to do it and they are asking you some stupid question that let you down the entire ticket.). So yes, save time and mark that questions to come back but...... keep everything in mind!!!

                       

                      Narbik, I am agree with you about the real world because I hate to see configurations with so many things that do nothing other than get your mind crazy. People who are not going the right things because It takes time and just go into the easy way. But let me tell you something that you probably already know, the lab is the lab....... you know what I mean right??

                       

                      Robert, very helpfull your links. Thanks a lot.

                        Nersas,

                         

                        I totally agree with what you are saying. The question is "Why would you configure extra commands?".

                        Most of the time the answer is one of the following:

                        1. Lack of knowledge
                        2. The question is very vague
                        3. You don't know your options
                        4. You do it because they don't subtract points.

                         

                        Is there another reason?

                         

                        I am sorry and i do not want to be rude or annoy anyone here, i teach this class every other week, and sometimes three times a week, almost all over the world, and i see that a lot, students tell me that extra configuration commands will not be penalised.

                        But they stop doing that once i ask them that same question, "Why would you configure extra commands????", ask yourself that question.

                         

                        But you are all correct and i agree with all of you.

                          Hi Narbik, I appreciate your constructive criticism and I don't think it's rude to say, I would say realistic. I took my time to think about your question and..... It's a GOOD ONE!!!! jajajaja Well, It's my answer.

                           

                          "I will be honest telling you that some extra-configuration is about Lack of Knowledge. The CCIE is HUGE with a lot of topics and It's hard to get a deep knowledge about every one of them, specially about security and services (NO-CORE questions). What do you think about configuring a user view with some interfaces commands, some debugs or some deep, complex and especific staff. It's just an example, but anyway, I know It's not an excuse about the lack of knowledge.

                           

                          Sometime I don't really know my options, but I am working on, doing many labs and opening my mind to see out of the box.

                           

                          I didn't really find many vague questions, they usually be very specific about the questions and If you don't get it clear, read it again and you will see the light.

                           

                          And I don't make extra-configuration because they don't subtract points jajajaja"

                           

                          Let me finish the reply with one more option where I was attached in the beginning of my study, where I wrote A LOT OF extra-configuration. The reason was for

                           

                          5. Insecurity

                           

                          It's kind of a mix of the previous points. Narbik, that's question hit the entire discussion, thanks a lot.

                           

                          I am doing my best to get rid of the extra-configuration, Thanks everybody discussing this topic.
