Question 16

Refer to the exhibit.

CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What step can be done to troubleshoot the issue?

A.Verify the MPLS LSPs.

B.Configure BGP between CE and PE routers.

C.Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.

D.Confirm that IS-IS is running with metric-style narrow.

Question 17

Refer io the exhibit.

While applying the configurations on two routers an engineer notices that OSPF adjacency Between them remains down Through the ping test the engineer confirmed that both me routers have Layer 3 reachability between them Which action should me engineer take to make the adjacencies to full?

A.Delete the area 0 authentication message-digest command from the OSPF process in R2

B.Delete the area 0 authentication message-digest command from the OSPF process in R1

C.Enable OSPF just inside the router OSPF process not in the interfaces of any router

D.Enter the command ip ospf authentication in R2 interface

Question 18

Refer to the exhibit.

R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?

A.The BGP session comes up between R1 and R2, but not between R1 and R3.

B.The BGP session comes up between R1 and R3, but not between R1 and R2.

C.The BGP session comes up between R1 and R2 and between R1 and R3.

D.The BGP session does not come up between R1 and R2 and between R1 and R3.

Question 19

Refer to the exhibit. A network engineer is configuring router R3 to handle multicast streams, but Host-2 cannot send subscription messages to the IPTV source. Which configuration must the engineer apply to router R3 so it passes the IPTV stream to Host-2?

A.R3# configure terminal
R3(config)# no ip pim ssm default
R3(config)# interface gigabitethernet 1/0/0
R3(config-if)# ip pim sparse-mode

R3(config)# interface gigabitethernet 1/0/1
R3(config-if)# ip pim sparse-mode
R3(config-if)# ip igmp version 3
R3(config-if)# ip pim ssm default

B.R3# configure terminal
R3(config)# ip multicast-routing
R3(config)# interface gigabitethernet 1/0/0

R3(config)# interface gigabitethernet 1/0/1
R3(config-if)# ip pim sparse-mode
R3(config-if)# ip igmp version 3
R3(config-if)# ip pim ssm default

C.R3(config)# interface gigabitethernet 1/0/0
R3(config-if)# ip pim sparse-mode
R3(config)# interface gigabitethernet 1/0/1
R3(config-if)# ip pim sparse-mode
R3(config-if)# ip igmp version 3

D.R3(config)# interface gigabitethernet 1/0/0
R3(config-if)# ip pim sparse-mode
R3(config-if)# ip igmp version 3
R3(config)# interface gigabitethernet 1/0/1
R3(config-if)# ip pim sparse-mode
R3(config-if)# ip igmp version 3

Question 20

Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

A.hierarchical CLI

B.routing process enabled by default on all interfaces

C.show lp ospf topology command

D.DR support for topology management
