Which is the correct ping command ‘Host IPv4 only’ should use? 

A. ping 27.1.1.10 

B. ping 27.1.1.10 source 2001:db8:2::7001:10A 

C. ping 2001:db8:2::7001:10A

Q87. In Multicast Inter-AS VPN context, which BGP attribute should you use to overcome the Option B limitation due to a rewritten originator next-hop address in the network? 

A. connector 

B. AS path 

C. weight 

D. originator 

Answer:


Q88. Refer to the exhibit. Which statement is true? 

A. This is an inter autonomous unicast route. 

B. The BGP MED value is 26. 

C. This is an mVPN route. 

D. The route target value is 10.1.100.2:3. 

E. There is a route reflector in this network. 

F. The route did not import this route into the VRF one. 

Answer:


Q89. Refer to the exhibit. Why is R3 unable to install 1.1.1.1/32 in its routing table? 

A. 11.11.11.11/32 exists in the routing table, so the conditional advertising is not working. 

B. The route is filtered out by the ip prefix-list ROUTE-IN command. 

C. 11.11.11.11/32 is advertising in the BGP table, so conditional advertising is not working. 

D. The bgp redistribute-internal command is missing under the R2 BGP process. 

Answer:


Q90. Refer to the exhibit. R1 and R2 are multicast routers running PIM over Serial1/0. The PIM adjacency on R1 is not forming with the given configuration. What command can be entered on R1 to resolve the issue? 

A. no access-list 100 deny 103 any any 

B. no access-list 100 deny udp any anyeq 103 

C. no access-list 100 deny ip any host 224.0.0.1 

D. no access-list 100 deny ip any host 224.0.0.2 

Answer:

Explanation: 

All PIM protocols share a common control message format. PIM control messages are sent as raw IP datagrams (protocol number 103), either multicast to the link-local ALL PIM 

ROUTERS multicast group, or unicast to a specific destination.
