AVPN-IPv4

BLabel-IPv4

CEVPN MAC

DEVPN IP-Prefix

Answer : D

Question 2

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

AAn RD is prepended to an IPv4 prefix to form a VPN-IPv4 prefix.

BAn RD is used to indicate the VPRN service to which a route update is relevant.

CA unique RD value is assigned to each VPRN service.

DAn RD is a 64-bit value.

Answer : D

Question 3

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?

AMP-BGP address families label-ipv4 or label-ipv6 need to be supported on each of the edge routers.

BEither RSVP, LDP, or segment routing tunnels need to be established between regions.

CEither RSVP, LDP, or segment routing tunnels need to be established within each region.

DEach PE router needs to advertise an IP address as a labeled BGP route to identify the tunnel endpoint.

Answer : D

Question 5

Which of the following regarding BGP Path Identifier is FALSE?

APath-ID is a four-octet identifier pre-pended to the NLRI field of a BGP update.

BPath-ID is an optional transitive attribute used to advertise multiple paths.

CPath-ID uniquely identifies each path advertised to a neighbor.

DA BGP speaker that re-advertises a route must generate its own Path-ID.

Answer : B

Question 6

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?

AThe prefix is rejected.

BThe prefix's local preference is set to 20.

CThe prefix's community value is removed.

DThe prefix's community value is modified to 65200:2.

Answer : D

Question 7

AA full iBGP mesh is required among route reflectors.

BA route reflector can have both iBGP and eBGP clients.

CA router reflector disables the iBGP split-horizon rule for its clients.
