NO.21 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.22 On the Nokia 7750 SR, which of the following is NOT an address family that BGP supports?

IPv4

VPN-IPv4

Label-IPv4

MP-EVPN

NO.23 Which of the following attributes can be used to prevent route advertisement loops in a network using router reflectors?

MED

ORIGIN

CLUSTER_LIST

AS_PATH

NO.24 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.25 Which of the following statements regarding BGP shortcuts is FALSE?

MPLS tunnels are used to carry transit traffic across the network.

A full mesh of iBGP peering sessions is not required,

Edge and transit routers need to be configured with BGP.

The transit routers need to support LDP or RSVP-TE LSPs.

NO.26 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.

NO.27 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.

NO.28 An autonomous system has 7 routers configured with BGP. How many iBGP sessions are required for a fully meshed configuration?

NO.29 Which of the following route reflection rules is NOT followed by a route reflector?

If the best route is received from an eBGP peer, propagate to all iBGP peers.

If the best route is received from an eBGP peer, propagate to all eBGP peers.

If the best route is received from a client, propagate to all iBGP peers.

If the best route is received from a client, do not propagate to eBGP peers.

NO.30 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.
