Question 1

Which is the primary function of a MPLS L3 VPN route target?

Options :

A : It imports and exports identified routes into selected VRFs.

B : It uniquely identifies NLRIs that have the same numeric value.

C : It imports the external routes it identifies into VRFs that support Internet traffic

D : It supports QoS by classifying traffic by file type when it applies MPLS EXP bits to each packet.

Answer: A

Question 2

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 3

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 4

A network engineer is implementing Layer 3 MPLS VPNs on Cisco IOS/IOS XE PE routers. Which PE-to-CE routing protocol requires a separate routing process to be created for each VRF?

Options :

A : RIPv2

B : OSPF

C : BGP

D : EIGRP

Answer: B

Question 5

An engineer noticed that PE3 is failing to accept IPv6 traffic information from PE1 The engineer confirmed that both PE3 and PE1 routers are configured accurately with IPv6 protocol To eliminate IPv6 traffic loss issue, which action must the engineer take to solve the problem?

Options :

A : Disable 6PVE that provides local IPv6 reachability over MPLS.

B : Configure 6PE that provides global IPv6 reachability over IPv4 MPLS

C : Allow PE routers use the MP-iBGP extensions in the IPv6 network configuration to exchange IPv6 reachability information.

D : Configure 6PE forwarding between 6PE routers based on the IPv6 header
