C. uRPF on all external facing interfaces at the edge routers 

D. Redistribution into BGP of the static route that points to the IP address of the attacker

Q5. Refer to the exhibit for the outputs from an ASR9K router. 

Why did the ping fail? 

A. The ping command is missing the ipv6 option: ping ipv6 2001:db8:10:1:10::1/128 

B. There is a problem with the IS-IS configurations 

C. The fe80::eab7:48ff:fe2c:a180 next-hop is not reachable 

D. The prefix length should be removed from the IPv6 address in the ping command: ping ipv6 2001:db8:10:1:10::1 

E. IPv6 is not enabled on the Gi0/0/0/0 interface 

F. The IPv6 neighbor discovery protocol is not enabled on the Gi0/0/0/0 interface

Q6. What is one of the configuration errors within an AS that can stop a Cisco IOS-XR router from announcing certain prefixes to its EBGP peers? 

A. Some prefixes were mistagged with the no-export BGP community 

B. Some prefixes were set with an MED of 0 

C. The outbound BGP route policy only has set actions defined without any pass actions defined 

D. The inbound BGP route policy only has set actions defined without any pass actions defined

Q7. Which three statements are correct regarding PIM-SM? (Choose three.) 

A. There are three ways to configure the RP: Static RP, Auto-RP, or BSR 

B. PIM-SM only uses the RP rooted shared tree and has no option to switch over to the shortest path tree 

C. Different RPs can be configured for different multicast groups to increase RP scalability 

D. Candidate RPs and RP mapping agents are configured to enable Auto-RP 

E. PIM-SM uses the implicit join model

Q8. When implementing high-availability stateful switchover BGP routing, in which situation would Cisco NSR be required? 

A. On the PE routers connecting to the CE routers which are not NSF aware or are not NSF capable 

B. On the PE routers connecting to the CE routers which support graceful restart 

C. On the PE routers connecting to the CE routers which are incapable of performing stateful switchover operations because the CE routers are only NSF aware but not NSF capable 

D. On the PE routers connecting to the CE routers which are incapable of performing stateful switchover operations because the CE routers are only NSF capable but not NSF aware 

E. On the service provider core P routers which are also NSF aware 

F. On the service provider core P routers which are also NSF capable

Q9. Which three statements regarding NAT64 operations are correct? (Choose three.) 

A. With stateful NAT64, many IPv6 address can be translated into one IPv4 address, thus IPv4 address conservation is achieved 

B. Stateful NAT64 requires the use of static translation slots so IPv6 hosts and initiate connections to IPv4 hosts. 

C. With stateless NAT64, the source and destination IPv4 addresses are embedded in the IPv6 addresses 

D. NAT64 works in conjunction with DNS64 

E. Both the stateful and stateless NAT64 methods will conserve IPv4 address usage
