An autonomous system has 7 routers configured with BGP. How many iBGP sessions are required for a fully meshed configuration?

• 7
• 13
• 21
• 42

A router in AS 65100 receives three routes for 138.120.0.0/16. The first route has an AS Path of 65200 65400 65300 and a local preference of 150. The second route has an AS Path of 65200 65300 and a local preference of 100. The third route has an AS Path of 65600 65300 and a local preference of 100. Which route will appear in the RIB-out?

• Only the first route will appear in the RIB-Out.
• Only the second route will appear in the RIB-Out.
• Only the third route will appear in the RIB-Out.
• All routes will appear in the RIB-Out.

Which BGP message type is used to verify connectivity during and after BGP session establishment?

• Hello
• Update
• Open
• Keep-Alive

Which of the following statements about BGP is FALSE?

• Peers need to be IP reachable to establish a BGP session.
• Route reflectors can reduce the number of iBGP sessions required.
• iBGP peers have to be adjacent to each other.
• The multihop parameter needs to be configured when eBGP peers are not adjacent to each other.

Which of the following statements about route reflector clusters is FALSE?

• Multiple clusters may be configured within an AS.
• Within an AS, route reflectors belonging to different clusters do not need to be fully-meshed among themselves.
• A router can be the client of multiple route reflectors within its AS.
• When a route reflector reflects a route, it adds its cluster ID to the Cluster_list attribute.

Which of the following statements about the MED BGP path attribute is FALSE?

• The MED BGP path attribute is transitive.
• The MED BGP path attribute is optional.
• Routes having lower values in their MED BGP path attribute are preferred.
• The MED BGP path attribute's value is set by a router at the edge of an AS.

A BGP router receives the following routes. 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 eBGPneighbor2: 192.169.20.0/24 with local preference 100, MED 100, AS Path 63200 from an iBGP neighbor3: 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

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

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

Which of the following statements about VXLAN encapsulation is TRUE?

• It uses an MPLS label to identify the transport tunnel and a VXLAN Network ID (VNI) to identify the service tunnel.
• It uses a VXLAN Network ID (VNI) to identify the transport tunnel and an MPLS label to identify the service tunnel.
• It uses an additional IP header to identify the transport tunnel and a VXLAN Network ID (VNI) to identify the service tunnel.
• It uses VXLAN Network ID (VNI) to identify the transport tunnel and an additional IP header to identify the service tunnel.

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

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