Question 1

What is a requirement to share VRF reachability information to all members of a VPN when using IPv6?

Options :

A : PE and CE routers must be running BGP as the PE-CE routing protocol

B : PE routers must have MPLS disabled and be running MP-BGP between all P and PE routers.

C : PE routers must be running MP-BGP and bgp default ipv4-unicast must be disabled

D : All PEs must have the same VRFs configured.

Answer: D

Question 2

An ISP provides a major client MPLS VPN for managed services. The MPLS engineering team needs to use the advanced VPN feature of selective VRF import so that only specific prefixes are present in the required VPNs.

Which aspect of this feature must the team consider?

Options :

A : A route must pass the import route map first and then the route target import filter.

B : The routers that are imported in the VRF can be BGP and IGP routes, so other match conditions in the route map, besides communities, can be used.

C : The import-map command is applied under the PE interface that connects to the CE router.

D : A route is imported into the VRF only when at least one RT that is attached to the route matches one RT that is configured in the VRF and the route is permitted by the import route map.

Answer: D

Question 3

The network engineering group of a large ISP needs to harden the management plane of its Cisco 9000

Series ASRs. While addressing IPv6 ICMP issues, they realized they have to limit the rate at which IPv6 ICMP error messages are sent out on the network. Which command do they need to apply?

Options :

A : icmp ipv6 rate-limit unreachable 1000

B : ipv6 rate-limit 1000

C : icmp ipv4 rate-limit unreachable 1000

D : ipv6 icmp error-interval 50 20

Answer: D

Question 4

What do EVPN single-active and all-active have in common?

Options :

A : They are default gateway redundancy options.

B : They are multihoming mechanisms used for CE devices.

C : They are used to provide single connection from a CE device to a service provider.

D : They are both roles that a designated router can take when MPLS is used with EVPN.

Answer: D

Question 5

Refer to the exhibit.

If the two devices are operating normally, which two conclusions can you draw from this configuration? (Choose two.)

Options :

A : CE1 must use OSPF to establish a neighbor relationship with PE1.

B : PE1 labels the routes it learns from CE1 with the route-target 222:2 and shares them with its VPNv4 peers.

C : PE1 labels the routes it learns from CE1 with the route-target 111:1 and shares them with its VPNv4 peers.

D : The PE-CE routes between the devices are being exchanged by OSPF

E : CE1 is supporting CSC.
