Hi, I'll be taking the exam shortly. I was hoping someone could help me with a few questions.
------------- q1. Two advantages of using subinterfaces in NBMA topology? a. ip address space conserved b. routing protocols avoid split horizon c. logical interfaces more reliable that physical d. when subinterface state changes to down, the physical remains up I know b is one correct answer. I was then looking at either c or d as the other answer. However I have read somewhere that a subinterface cannot change its state to down, it always remains up, so long as the physical interface remains up. My answer: B & C ---------------- q2. youre configuring network routers with IBGP. What is true about BGP peer group in the network? a. peer members inherit all options of the peer group b. peer groups can be used to simplify BGP configs c. peer groups are optional non-transitive attributes of BGP d. a peer group allows options that affect outbound updates to be overridden. e. a common name should be used on all routers because this information is passed between neighbours I know A is wrong because you can set attributes per router and these will override peer group options. B is correct. With C, 'peer group' isnt defined under the attribute list... so this is wrong. D is wrong as it only allows options for inbound. E is a little strange as I thought neighbours are defined by using the 'neighbor' command, not by giving the router a common name. Well maybe this common name is the name of the peer group defined in the 'neighbor' command, so maybe this is correct. My answer: B & E ---------------- How is the test in general? What is the duration of the exam? I noticed that I wasn't able to book the exam at my regular testing centre. I think this is due to the fact that the 640-901 exam is a flash exam and required additional software to get it up and going. Thanks so much for your help.
