QUESTION 38
You are troubleshooting an EVPN-VXLAN IP fabric and observe the loop shown in the exhibit.
Which two steps would you take to further troubleshoot this problem? (Choose two.)

Verify that the same ESI is configured on the link from the host and that it matches the source.

Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.

Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.

Verify that the same ESI is configured on the two links from the source.

QUESTION 39
Referring to the exhibit, a RMSM network is set up to enable communication between multicast devices.
Which statement is true in this scenario?

After the formation of the shortest-path tree, a join message is sent from R2 to R1.

After the formation of the shortest-path tree, a join message is sent from R1 to R5

After the formation of the shortest-path tree, a prune message is sent from R1 to R2.

After the formation of the shortest-path free, a prune message is sent from R1 to R5.

QUESTION 40
You are deploying IP phones in your Layer 2 network and are asked to ensure that the switch sends VLAN and CoS information to the IP phones automatically.
In this scenario, which protocol should be used?

PoE

PoE+

LLDP

LLDP_MED

QUESTION 41
Which statement is correct about IS-IS?

IS-IS uses areas and an autonomous system.

Level 1/2 routers automatically inject a default route to the nearest Level 1 router.

Level 2 routers must share the same area address.

Level 1 routers route traffic between autonomous systems.

QUESTION 42

policer > multifield classifier -> BA classifier

QUESTION 43
You are troubleshooting a route problem in the topology shown in the exhibit. The 10.30.0 0/24 route is not reachable from the R3 router. What would cause this problem?

R3 does not have a route to the BGP next hop of 10.30.0.0/24

R4 is not advertising the 10.30.0.0/24 route to R3

R3 does not have an established BGP session with R4.
