They all have the same 64-bit subnet prefix.

NO.24 Which of the following statements about EVPN services is FALSE?

The goal of an EVPN service is to provide layer-2 or layer-3 connectivity among two or more customer sites.

A local layer-2 EVPN service is referred to as a backhaul VPLS.

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.

EVPN services support signaling for the use of MPLS and VXLAN tunnels.

Router RA prefers the update received from router RR1.

Router RA prefers the update received from router RR2.

Router RA flags both updates as invalid.

Router RA accepts both updates and flags them as used.

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.

NO.27 The configuration of an Nokia 7750 SR is given below. Router Rl has established BGP sessions with routers R2 and R3. Which of the following is TRUE?

Router R1forms an iBGP session with router R2, and an eBGP session with router R3.

Router R1forms iBGP sessions with routers R2 and R3.

Router R1forms eBGP sessions with routers R2 and R3.

EVPN MAC

EVPN IP-Prefix

NO.30 Which of the following statements about a distributed EVPN VPRN service is FALSE?

It acts as a router, carrying IP packets between customer sites.

It requires two types of interfaces, one towards customer sites and one towards the backhaul VPLS.

Its configured route target indicates to the PE router which of the received BGP route updates are relevant to this VPRN.

It relies on MP-BGP and on the EVPN address family to populate its routing table.

NO.31 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?

The service label is advertised using LDP.

The service label is prepended to the customer IPv4 prefixes.

The service label must be manually configured for the VPRN on each PE router.

The service label is carried in an MP-BGP VPN-IPv4 route update.

NO.32 A BGP session is stuck in the “Connect” state. Which of the following is the most likely reason?

The remote BGP peer is properly configured but the local router is not.

The local router is properly configured but the remote BGP peer is not.

The BGP protocol is administratively disabled on the local router.

The BGP protocol is administratively disabled on the remote BGP peer.

NO.33 Click the exhibit.

7750 SR router A can establish an IPv6 BGP session to router B?

Option A

Option B

Option C

Option D

NO.34 A TCP connection fails to be established with a BGP peer. Which of the following are valid options for the BGP connection state?

Idle or Connect

Idle or Active

Connect or Active

Connect or Open Sent

NO.35 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.

NO.36 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.

NO.37 Which of the following regarding route reflectors is TRUE?

Only the route reflector is configured with a cluster id.

There can only be one route reflector in a cluster.

Clients should have iBGP sessions with each other to maintain the mesh.

There can only be one level of route reflectors in the topology.

NO.38 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?

Option A

Option B

Option C

Option D

NO.39 Which of the following is considered a best practice for BGP address planning?

Advertising external networks into IGP.

Using system addresses for setting up iBGP sessions.

Exporting the networks associated with the external links of eBGP peers into BGP.
