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?

Q17. 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?

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

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

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

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

Q18. An export policy is applied on a router to advertise a prefix to its eBGP peers. By default, which of the following updates are made to the route attributes?

LOCAL_PREFERENCE is set to 100.

NEXT_HOP is set to the neighbor router’s interface IP address.

The local AS number is added to AS_PATH.

COMMUNITY is set to the local AS number.

Q19. What is the result of configuring the following policy statement as a BGP import policy on the Nokia 7750 SR?

All BGP routes are accepted.

All routes matching prefix lists “List-1” and “List-2” are rejected.

BGP routes matching prefix lists “List-1” or “List-2” are rejected.

BGP routes matching prefix lists “List-1” and “List-2” are rejected.

Q20. What type of information does a type-2 EVPN route update carry?

It carries an IP prefix and its associated mask.

It carries an IP address and requests the MAC address of the corresponding host.

It carries a host MAC address and optionally the associated IP address that belongs to the same host.

It carries a host MAC address and optionally the IP prefix of the subnet where the host is located.

Q21. 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.

Q22. Which of the following pieces of information is NOT carried inside an EVPN IP-Prefix (type 5) route update associated with an EVPN VPLS?

The MAC address of an attached host.

The IP prefix of a subnet in the layer-3 domain that the VPLS belongs to.

The VPLS’s route-distinguisher and route-target values.

The VPLS’s service tunnel ID (MPLS label or VNI value).

Q23. Which of the following statements about router reflectors is FALSE?

A full iBGP mesh is required among route reflectors.

A route reflector can have both iBGP and eBGP clients.

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

Route reflectors are used to reduce the number of iBGP sessions required in an AS.

Q24. Click the exhibit.

An update travels from AS 137000 to AS 135000, traversing both 32-bit and 16-bit AS Paths.
What AS Path is seen by AS 200?

140000 137000

137000 140000

Q25. Which of the following regarding BGP Path Identifier is FALSE?

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

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

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

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