In the diagram, the BGP import policy "north-and-south" is applied to router R5. Router R1
advertises the prefix 140.100.1.0/24 with a community set to "65200:1". Which of the following
statements about how router R5 processes the received route update for prefix 140.100.1.0/24 is
TRUE?

• A. The prefix is rejected.
• B. The prefix's local preference is set to 20.
• C. The prefix's community value is removed.
• D. The prefix's community value is modified to 65200:2.

• C. Label-IPv4
• D. MP-EVPN

In the diagram below, a data packet is sent from CE1 to a far-end CE2 over a VPRN service across
multiple regions. Which of the following statements about the tunnel labels is FALSE?

• A. The outer label is an RSVP, LDP, or segment routing label pushed by router Core1.
• B. The second label is a BGP label pushed by router RBR1.
• C. The service label is a label pushed by router PE1.
• D. The outer label will be popped by router Core2.

In the diagram below, an end-to-end transport tunnel needs to be established between PE1 and PE2
using MP-BGP. Which of the following items is NOT required?

• A. MP-BGP address families label-ipv4 or label-ipv6 need to be supported on each of the edge routers.
• B. Either RSVP, LDP, or segment routing tunnels need to be established between regions.
• C. Either RSVP, LDP, or segment routing tunnels need to be established within each region.
• D. Each PE router needs to advertise an IP address as a labeled BGP route to identify the tunnel endpoint.

Which of the following statements about IPv6 Link-Local addresses is FALSE?

• A. They are assigned to every physical interface running IPv6.
• B. They are only valid for communication within the same broadcast domain.
• C. They all have the same 64-bit subnet prefix.
• D. They have an interface ID derived by default from the interface’s IPv4 address.

A traditional (non EVPN) VPRN service is configured using MP-BGP and LDP transport tunnels. Which
of the following statements about the VPN service label is TRUE?

• A. The service label is advertised using LDP.
• B. The service label is prepended to the customer IPv4 prefixes.
• C. The service label must be manually configured for the VPRN on each PE router.
• D. The service label is carried in an MP-BGP VPN-IPv4 route update.

Which of the following statements about Route Distinguishers (RD) is FALSE?

• A. An RD is prepended to an IPv4 prefix to form a VPN-IPv4 prefix.
• B. An RD is used to indicate the VPRN service to which a route update is relevant.
• C. A unique RD value is assigned to each VPRN service.
• D. An RD is a 64-bit value.

Which of the following statements about EVPN services is FALSE?

• A. The goal of an EVPN service is to provide layer-2 or layer-3 connectivity among two or more customer sites.
• B. A local layer-2 EVPN service is referred to as a backhaul VPLS.
• C. The same BGP address family can be used to populate the forwarding database of an EVPN VPLS and the route table of an EVPN VPRN.
• D. EVPN services support signaling for the use of MPLS and VXLAN tunnels.

What does an EVPN VPLS do that a traditional VPLS does not do?

• A. It provides a multipoint connectivity service.
• B. It maintains a forwarding database.
• C. It uses control-plane MAC learning.
• D. It acts as a switch, carrying full layer-2 frames between customer sites.

The diagram shows EVPN services and their associated route-target (RT) values. For the distributed
VPRN service in the diagram, what will be the route-target value included in the EVPN routes
exchanged between routers PE1 and PE2 to populate the VPRN's route table?

• A. 65200:100
• B. 65200:200
• C. 65200:300
• D. 65200:400
