  You are evaluating which method to use for learning MAC addresses in your VXLAN network. Which statement is true in this scenario?

  A. Multicast exchanges MAC addresses through data plane learning and is more reliable than EVPN.

  B. EVPN exchanges MAC addresses through control plane learning and is more reliable than multicast.

  C. EVPN exchanges MAC addresses through data plane learning and is more reliable than multicast.

  D. Multicast exchanges MAC addresses through control plane learning and is not more reliable than EVPN.

  Correct Answer: B

• Question 46:

  Which two statements describe EVPN based VXLAN implementations? (Choose two.)

  A. MAC addresses ate propagated using BGP updates

  B. MAC addresses are learned using multicast flooding

  C. The movement of a virtual host results in the dynamic remapping of the VTEP

  D. The movement of a virtual host requires a manual reconfiguration of the VTEP

  Correct Answer: AC

• Question 47:

  Referring to the exhibit,

  

  what happens when you initiate ZTP on a QFX5120 switch running Junos 21.3R1.9?

  A. ZTP skips both the Junos installation and the configuration.

  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.

  Correct Answer: C

• Question 48:

  You are designing a Layer 3 fabric underlay using EBGP. You will implement an E VPN- signaled VXLAN overlay on the Layer 3 fabric.

  In this scenario, what must you do in the underlay to ensure that the VXLAN overlay will be able to function properly?

  A. The underlay should support the PIM protocol

  B. Each device in the underlay should advertise its loopback address

  C. The underlay should be configured with a separate VRF tor each potential tenant

  D. The underlay should advertise the host connected interlaces on all leaf device

  Correct Answer: B

• Question 49:

  An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit.

  Host1 is a bare metal server, and is dual-homed to the network. The IP addresses 10.1.1.1/24 and 10.1.1.2/24 are assigned to the same physical NIC, and no virtualization is configured on the server.

  

  In this scenario, which two statements are true? (Choose two.)

  A. The MAC address associated with 10.1.1.1/24 and 10.1.1.2/24 will be same when advertised to leaf3.

  B. Traffic from IP address 10.1.1.1/24 must traverse the VXLAN network to reach IP address 10.1.1.2/24

  C. The connection host1 to devices leaf1 and leaf2 must be configuration a LAG.

  D. The ESI assigned to the host1 link must be the as the ESI assigned to the leaf2 host1 link.

  Correct Answer: CD

• Question 50:

  You administer an EVPN-VXLAN fabric. You notice that there is no VXLAN traffic forwarding through the network.

  

  Referring to the exhibit, which modification will solve the problem?

  A. set firewall family inet filter allow-BGP term 1 from protocol udp set firewall family inet filter allow- BGP term 1 from destination-port 4789

  B. set interfaces et-0/0/49 unit 0 family vxlan

  C. set interfaces et-0/0/49 unit 0 family vpls

  D. set firewall family inet filter allow-BGP term 1 from protocol tcp set firewall family inet filter allow- BGP term 1 from destination-port 4789

  Correct Answer: A
