Drag and drop the EVPN components from the left onto the correct planes on the right.

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

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.

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?

A. headend

B. source

C. transit

D. bud

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?

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.

While configuring the VRF Selection feature, you get an error message after typing the below statement:

Router(config)#no vrf selection source 172.16.0.0 255.255.0.0 vrf VRF1

Which action caused this message?

A. the entry of an inconsistent IP address and mask for VRF Selection

B. an attempt to configure a VRF instance on an interface that already has VRF Selection configured

C. an attempt to remove a VRF Selection entry that does not exist

D. an attempt to configure a VRF Selection table that does not exist

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. TCP MD5 authentication

B. control message hashing

C. CHAP authentication

D. control message rate limiting

E. asymmetric mutual authentication with PSK

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.

Which statement describes the no bgp default route-target filter command?

A. Prefixes that are received with route targets and distinguisher are accepted.

B. Prefixes that are received with route targets and distinguisher are not accepted.

C. Prefixes that are received with route targets that are not imported at the PE are not accepted.

D. Prefixes that are received with route targets that are not imported at the PE are accepted.

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. 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
