Question 1

A client with five data centers spread around the country uses MPLS L2VPNs to provides point- to- point data center interconnect between each data center in a full-mesh network. The client Is considering an MPLS EVEN implementation.

In this scenario, what are three advantages of using MPL5 EVEN interconnects? (Choose two.)

Options :

A : The provide for static configuration that does not require a Dynamic Routing Protocol

B : They provide for a local proxy ARP/ND resolution.

C : They provide for point to multipoint connectivity

D : They provide for a MAC learning in the control plane.

E : They provide for lower transmission latency.

Answer: B,C,D

Question 2

Options :

A : Ensure that all spine devices are the same switched mode.

B : Ensure that all uplinks are 40GbE.

C : Ensure that every leaf node has an uplink spine node

D : Ensure that every node has a link to every other leaf node

Answer: A,C

Question 3

B : ZTP performs the Junos installation but skips the configuration.

C : ZTP performs both the Junos installation and the configuration.

D : ZTP skips the Junos installation but applies the configuration.

Answer: B
