Question 1

Which EVPN router type prevents BUM traffic from looping back to a multihued host?

A. Ethernet segment router

B. IP prefix route

C. Inclusive multicast-Ethernet tag route

D. Ether auto discovery route

Correct Answer: D

Question 2

You are deploying a VXLAN using signaling overlay network in your new data center. You are able to establish your MP BGP peering session and see your EVPN routes, but traffic will not traverse the VXLAN using signaling overlay network.
What is a solution to this problem?

A. Increase the physical MTU on all ports on all devices participating in VXLAN using EVPN signaling.

B. Increase the protocol MTU on all devices participating in VXLAN using EVPN signaling

C. Increase the MTU on the logical VTEP source interface of all devices participating in VXLAN using EVPN signaling.

D. Enable the mtu-discovery feature on the MP peering sessions between VXLAN ANs EVPN signaling peers.

Correct Answer: A

Question 3

Which two statements define the use of route targets and route distinguishers in an EVPN? (Choose two.)

A. Route targets ensure that routes from different clients remain unique within the data center domain

B. Route targets identify the VRF into which the route should be placed

C. Route distinguishers ensure that routes from different client remain unique within the data center domain

D. Route distinguishers identify the VRF into which the route should be placed

Correct Answer: B,C

Question 4

What happens when a packet is encapsulated by a VXLAN before being placed in the overlay?

A. The QoS marketing are placed in the VXLAN header.

B. The TTL is decremented by two and placed in the VXLAN header.

C. The VLAN-ID is placed in the VXLAN header.

D. A VNI that maps to the VLAN-ID placed in the VXLAN header.

Correct Answer: D

Question 5

Which protocol is used between VCF member devices to create a loop-free topology?

A. RSTP

B. MDTP

C. VCCP

D. LLDP

Correct Answer: C

Question 6

You are implementing perimeter security for your data center. You need to inspect all traffic Layer 7 and ensure the failure of a port or device will not result in an interruption to traffic flows.

A. SRX Chassis cluster

B. QFX Virtual Chassis

C. SRX using LAG

D. MX with MC LAG

Correct Answer: A
