Exam 300-410 topic 1 question 16 discussion

C seems the most logical considered some packets have matched and some other not

Labbed with 3 routers the peers i set with ACL in class map could no establish session so C is correct.

with this (below) ACL both incoming (179) and outgoing (179) are blocked. BGP cannot be established. R7#show ip access-lists Extended IP access list ACL_BGP 10 permit tcp any any eq bgp (45 matches) 20 permit tcp any eq bgp any (3 matches) R7#sh policy-map control-plane Control Plane Service-policy input: CoPP_IN Class-map: CL_BGP (match-all) 76 packets, 4826 bytes 5 minute offered rate 0000 bps, drop rate 0000 bps Match: access-group name ACL_BGP drop Class-map: class-default (match-any) 237 packets, 55172 bytes 5 minute offered rate 0000 bps, drop rate 0000 bps Match: any R7#

it´s C

The A is correct because default class map has number Id 0 and other class map configured will take high number id 1or2

C is correct

The correct answer is C

The correct answer is C

Ok so if the router can form BGP neighbourships with any other device, what are the marked packets 2716 ? These are dropped packets no ?

The correct answer is: C

The correct answer is: C

The given answer is correct then A. The question refers about the control-plane protection mechanism.. The configuration shows that the router is still gonna etablish the BGP relationship to a given number of peers, but not all( because of policy assigned to that class-map based on rate-limit condition)

Its C, whoever admins this site is a nuffie.

C - labbed and existing neighbours that matched the ACL go down.

Not sure if the answer is A or C. One class-map states drop any thing name BGP, and another Class map states allow any.

The correct answer is C

C should be correct
