Which kind of traffic is supported in an MVPN Extranet?

A.

PIM dense mode with Reverse Path Forwarding

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

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.

Refer to the exhibit.

Which statement about this command is true?

A.

It must be configured on each PE router to enable the PE routers to receive multicast traffic for this particular MVRF.

B.

It is used to set the designated router on a link using PIM-SM.

C.

It must be configured on the PE and CE router to enable MP-BGP to send labels for CSC.

D.

It is used to set the router that will server as the root bridge for STP.

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.)

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

Refer to the exhibit.

Which statement about this configuration is true?

A.

Router 1 will accept multicast routes with a route-target of 12:1.

B.

192.168.1.2 must be reachable by all routers participating in the mvpn-intranet MVRF.

C.

Router 1 has statically defined thresholds for data MDT.

D.

The MVRF must be configured on each router on the customer and service provider networks.

Refer to the exhibit.

Which statement describes the result of this configuration?

A.

R1 redistributes BGP routes into the OSPF process of VRF custabc as E1 routes.

B.

R1 redistributes BGP routes into the OSPF process of VRF custabc as E2 routes.

C.

R1 mutually redistributes routes between BGP 65001 and the OSPF process of VRF custabc.

D.

R1 redistributes BGP routes into the OSPF process of VRF custabc as OIA routes.

How do Ethernet virtual circuits provide a way for service providers to maximize the use of VLAN tags'-1

A.

They add an additional tag to VLANs that allows up to two switch ports to use the same globally configured VLAN ID.

B.

They redefine the VLAN tag to include classification, forwarding, and QoS using MPLS labels and EXP bits

C.

They separate the classification and forwarding concepts for VLAN tagging which allows multiple switch ports to use the same VLAN ID without it being configured globally.

D.

They assign VLAN IDs to VTP domains so that the same VLAN ID are used more than once globally.

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?

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
