문제1

The CTO of a company requires the support of a network consultant to deliver an MPLS solution without resigning to a certain degree of redundancy and scalability. Which solution effectively scales to hundreds or thousands of sites?

A. L2VPN by encapsulating multiple frame formats with interworking.

B. L2VPN with the broadcast traffic processed at the ingress PE.

C. L3VPN using a hierarchical topology of N-PEs and U-PEs.

D. L3VPN with direct LSP connectivity between all PEs.

정답: C

문제2

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?

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

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

C. Configure 6PE forwarding between 6PE routers based on the IPv6 header

D. Configure 6PE that provides global IPv6 reachability over IPv4 MPLS

정답: D

문제3

In Layer 3 MPLS VPN implementations, if some of the VPNv4 routes on one PE router do not appear on another PE router, what could be the problem?

A. RD mismatch between the PE routers

B. RT export and import configuration errors

C. RD export and import configuration errors

D. VRF name mismatch between the PE routers

정답: B

문제4

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

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

B. It imports the external routes it identifies into VRFs that support Internet traffic

C. It imports and exports identified routes into selected VRFs.

D. It uniquely identifies NLRIs that have the same numeric value.

정답: C

문제5

A network architect is troubleshooting the L2TPv3 tunneling security due to the untrusted nature of the underlaying network. Which two L2TPv3 features does the architect deploy to address the ongoing issues? (Choose two.)

A. control message hashing

B. TCP MD5 authentication

C. control message rate limiting

D. CHAP authentication

E. asymmetric mutual authentication with PSK

정답: A,D

문제6

Refer to the exhibit. Router 1 is a route reflector client within a service provider core.
PE1 cannot see VPNv4 routes received from the ASBR.
PE1 only has an iBGP relationship with Router 1.
Which action resolves this issue?

A. Configure Router 1 as a route reflector for PE1 under the VPNv4 address family.

B. Configure PE1 to have an eBGP relationship with Router 1.

C. Enable BGP default ipv4-unicast

D. Activate PE1 as a neighbor under the IPv4 address family.

정답: A

문제7

Refer to the exhibit. A customer carrier running MPLS VPN wants to utilize a backbone carrier to forward traffic and exchange VPNv4 prefixes between the two customer carrier networks depicted.

B. CC-PE-A and CC-PE-B

C. BB-PE-A and CC-PE-B

D. CC-PE-A and BB-PE-A
