Options:

A.

RP/0/RP0/CPU0:PE(config-bgp)#

B.

RP/0/RP0/CPU0:PE(config-if)#

C.

RP/0/RP0/CPU0:PE(config-bgp-af)#

D.

RP/0/RP0/CPU0:PE(config-vrf)#

Question 5

What is the effect of this configuration?

Options:

A.

The mroute table is cleared.

B.

Router 1 accepts multicast routes with a tag of 12:1

C.

A Cisco MPLS TE tunnel is generated with 192.168.1.2 as the source IP address of router 1.

D.

An LSP virtual interface tunnel is created.

Question 6

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 carriers networks depicted. Which two sets of routers must establish MP-iBGP sessions? (Choose two.)

Options:

A.

BB-PE-A and CC-PE-B

B.

CC-PE-A and CC-PE-B

C.

BB-PE-A and BB-PE-B

D.

CC-PE-A and BB-PE-A

E.

BB-PE-A and BB-P-A

F.

CC-PE-A and CC-P-A

Question 7

Refer to the exhibit.

An engineer is implementing an MPLS P2MP TE solution. Which type of router can serve as the midpoint router and the tailend router in this P2MP TE network implementation?

Options:

A.

headend

B.

source

C.

transit

D.

bud

Question 8

What is the primary function of a VRF on a router?

Options:

A.

It enables the router to support multiple separate routing tables, which allows the device to handle overlapping IP addresses.

B.

It enables a router to run BGP and a distance vector routing protocol at the same time, which allows it to serve as a VPN endpoint between remote sites.

C.

It enables a router to configure VLANs locally, which provides segregation between networks.

D.

It enables the router to provide faster switching through the network by using labels to identify the input and output interfaces for neighbor routers.

Question 9

Which two statements describe primary differences between MPLS Layer 2 and Layer 3 VPNs? (Choose two.)

Options:

A.

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use L2TPv3 tunneling.

B.

Layer 2 VPNs use AToM, but Layer 3 VPNs use MPLS/BGP.

C.

Layer 2 VPNs use BGP, but Layer 3 VPNs use VPLS.

D.

Layer 2 VPNs use L2TPv3 tunneling, but Layer 3 VPNs use GRE tunneling.

E.

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use pseudowires to provide tunneling.

Question 10

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.
