Which route is selected as best route?
1: 192.169.20.0/24 with local preference 100, MED 150, AS Path 65300 65200 from an eBGP neighbor
2: 192.169.20.0/24 with local preference 100, MED 100, AS Path 63200 from an iBGP neighbor
3: 192.169.20.0/24 with local preference 200, MED 150, AS Path 65400 63200 from an iBGP neighbor
4: 192.169.20.0/24 with local preference 200, MED 100, AS Path 63700 from an eBGP neighbor

Answer: B
Click the exhibit.
Router R1 is a route reflector with clients R2, R5 and R6. Prefixes advertised by router R5 have a local preference of 200. Router R3 advertises the prefix 192.168.1.0/27 to routers R5 and R6.
Assuming that none of the routers in AS 65540 is configured with "advertise-external", what is the expected output of "show router bgp routes" on router R5?
A . Option A
B. Option B
C. Option C
D. Option D
Answer: C
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.
Answer: C
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.
Answer: D
Which of the following regarding BGP Path Identifier is FALSE?
A . Path-ID is a four-octet identifier pre-pended to the NLRI field of a BGP update.
B. Path-ID is an optional transitive attribute used to advertise multiple paths.
C. Path-ID uniquely identifies each path advertised to a neighbor.
D. A BGP speaker that re-advertises a route must generate its own Path-ID.
Answer: B
A BGP session is stuck in the "Connect" state.
Which of the following is the most likely reason?
A . The remote BGP peer is properly configured but the local router is not.
B. The local router is properly configured but the remote BGP peer is not.
C. The BGP protocol is administratively disabled on the local router.
D. The BGP protocol is administratively disabled on the remote BGP peer.
Answer: B
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.
Answer: D
Which of the following statements about BGP peering sessions is FALSE?
A . BGP peers need IP reachability between them.
B. iBGP peers can be non-adjacent.
C. eBGP peers have to be adjacent to each other.
D. BGP peers can be configured with different AS numbers.
Answer: C
Which of the following statements about BGP is FALSE?
A . BGP uses Hello messages to dynamically discover BGP peers.
B. To establish a BGP session, a TCP session must first be established between the two routers.
C. BGP uses the OPEN message to exchange capability parameters between routers.
D. BGP was originally designed as an exterior routing protocol.
Answer: D
