Refer to the exhibit:

Assume all other configurations are correct and the network is otherwise operating normally. Which conclusion can you draw about the neighbor relationship between routers R1 and R2?

A.

The neighbor relationship will be up only if the two devices have activated the correct neighbor relationships under the IPv4 address family

B.

The neighbor relationship is down because R1 believes R2 is in AS 65012.

C.

The neighbor relationship is up

D.

The neighbor relationship is down because the loco I-as value for R2 is missing in the R1 neighbor statement

Refer to the exhibit. ISP ASN 65100 provides Internet services to router CE-1 and receives customer prefix 198.18.18.0/24 via eBGP.

Cisco(config)# interface ethernet 1/0 Cisco(config-if)# ip igmp max-groups action replace

B.

Cisco(config)# interface ethernet 1/0 Cisco(config-if)# ip igmp filter

C.

Cisco(config)# interface ethernet 1/0 Cisco(config-if)# ip igmp access-group 239.10.10.10

Cisco(config)# interface ethernet 1/0 Cisco(config-if)# ip igmp join-group 239.10.10.10

Refer to the exhibit.

An administrator working for large ISP must connect its two POP sites to provide internet connectivity to its customers. Which configuration must the administrator perform to establish an iBGP session between routers PE1 on POP site 1 and PE2 on POP site 2?

A.

PE2#configure terminal

PE2(config)#router bgp 65111

PE2(config-router)#no neighbor 172.18.10.1 shutdown

PE2(config-router)#end

B.

PE1#configure terminal

PE1(config)#router bgp 65111

PE1(config-router)#no neighbor 172.19.10.10 shutdown

PE1(config-router)#end

C.

Which component is similar to an EVPN instance?

A.

MPLS label

B.

IGP router ID

C.

VRF

D.

router distinguisher

Refer to the exhibit. Tier 1 ISP A purchased several Tier 2 ISPs to increase their customer base and provide more regional coverage. ISP A plans to implement MPLS services in the access layer, with scalability up to 100.000 devices In one packet network and service recovery up to 50 ms. The network architect decided to use different independent IGP and LDP domains and interconnect LSPs that are based on RFC 3107. Which two actions must the network engineer perform to meet the requirements? (Choose two.)

A.

Implement BGP PIC core functionality on routers R2 and R3.

B.

Configure three OSPF areas, with Area 0 In the core domain, and Areas 2 and 3 in the aggregation domain.

C.

Implement BGP connectivity between routers R1 and R4 with VPNv4 address family enabled.

D.

Implement BGP inline RR functionality with next-hop-self capabilities on routers R2 and R3.

E.

Implement the IS-IS routing protocol on the access domain.

Which feature describes the adjacency SID?

A.

It applies only to point-to-point links.

B.

It applies only to multipoint links

C.

It is locally unique

D.

It is globally unique.

While implementing TTL security, you issue the PE(config-router-af)#neighbor 2.2.2.2 ttl-security hops 2 command.

After you issue this command, which BGP packets does the PE accept?

A.

from 2.2.2.2, with a TTL ol 253 Of more

B.

from 2.2.2.2, with a TTL of less than 2

C.

to 2.2.2.2, with a TTL of less than 253

D.

to 2.2.2.2, with a TTL of 2 or more

Refer to the exhibit. Router BRDR-1 is configured to receive the 0.0.0.0/0 and 172.17.1.0/24 network via BGP and advertise then into OSPF area 0. An engineer has noticed that the OSPF domain is receiving only the 172.17.1.0/24 route and default router 0.0.0.0/0 is still missing. Which configuration must an engineer apply to resolve this problem?

      Option A

      Option B

      Option C

A.

Option D
