Q1. Refer to the EBGP configuration on a PE IOS-XR router exhibit. 

After the EBGP configuration, no routes are accepted from the EBGP peer, nor are any routes advertised to the EBGP peer. 

What could be the problem? 

A. The update-source neighbor configuration command must also be configured 

B. The next-hop-self neighbor configuration command must also be configured C. EBGP neighbors must have an inbound and outbound route policy configured 

D. An access list is blocking IP protocol 179 packets between the two EBGP peers 

E. The maximum-prefix neighbor configuration command must also be configured 

Answer: C 

Q2. Which two statements regarding Auto RP operations and implementations are correct? (Choose two.) 

A. Candidate RPs send RP announcements to the 224.0.1.39 multicast group, and the mapping agents send RP discovery messages to the 224.0.1.40 multicast group

Answer: A,D

Q7. Refer to the exhibit. 

Which statement correctly explains the bgp graceful-restart command? 

A. This command is used to enable NSR and is entered on the NSR-capable router, and also on any NSR-aware peer 

B. This command is used to enable NSF and is entered on the NSF-capable router, and also on any NSF-aware peer 

C. This command is only required on the NSF-capable routers to enable BGP graceful restart with the BGP peers

Answer: B 

Q8. Which two statements correctly describe the BGP ttl-security feature? (Choose two.) 

A. This feature protects the BGP processes from CPU utilization-based attacks from EBGP neighbors which can be multiple hops away 

B. This feature prevents IBGP sessions with non-directly connected IBGP neighbors 

C. This feature will cause the EBGP updates from the router to be sent using a TTL of 1 

D. This feature needs to be configured on each participating BGP router 

E. This feature is used together with the ebgp-multihop command 

Answer: A,D 

Q9. You noticed a recent change to the BGP configuration on a PE router, the bgp scan time has been changed from the default value to 30s. Which three effects will this change have? (Choose three.) 

A. The BGP table will be examined and verified more frequently 

B. The BGP keepalive messages will be sent to the BGP peers at a faster rate 

C. The BGP table will be modified more quickly in the event that a next-hop address becomes unreachable

E. The minimum time interval between sending EBGP and IBGP routing updates will decrease 

F. The BGP convergence time will increase 

Answer: A,C,D
