Click the exhibit.

Routers RR1 and RR2 are route reflectors with the same Cluster-ID. How does router RA treat the updates for prefix 192.168.1.0/27 received from routers RR1 and RR2?

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.

NEW QUESTION 20
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.

NEW QUESTION 21
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.

NEW QUESTION 22
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.

NEW QUESTION 23
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?

The prefix is rejected.

The prefix’s local preference is set to 20.

The prefix’s community value is removed.

The prefix’s community value is modified to 65200:2.

NEW QUESTION 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.

NEW QUESTION 25
Which BGP message type is used to verify connectivity during and after BGP session establishment?

Hello

Update

Open

Keep-Alive

NEW QUESTION 26
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.

Option D

NEW QUESTION 28
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.

NEW QUESTION 29
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.

A unique RD value is assigned to each VPRN service.

An RD is a 64-bit value.
