• Question 72:

  The MC-LAG group shown in the exhibit is providing high availability services for the directly connected servers. The backup liveness detection is applied to the ICL-PL link, however, when one of the members rebooted, there was traffic loss for a few seconds.

  

  In this scenario, where should you apply the backup liveness detection?

  A. On the management interfaces

  B. On the ae2 interface

  C. On the ae1 interface

  D. On the ae0 interface

  Correct Answer: A

• Question 73:

  You host a multitenant data center that runs VMware. You must perform deep packet inspection on all inter-tenant traffic that is flowing between the VMs within the same hypervisor. Your solution must provide the security services without needing to leave the physical device. In this scenario, what should you do to solve this problem?

  A. Use separate vswitches to isolate each-tenant's network and use and use a vSRX device to evaluate inter-tenant traffic.

  B. Use VLANs to isolate each tenant's networks and use an SRX Series device to evaluate inter-tenant traffic.

  C. Use a VLANs to isolate each tenant's network and use IP tables to evaluates inter- tenant traffic.

  D. Use a vMX device to isolate each tenant's network and use firewall filters to evaluate inter-tenant traffic.

  Correct Answer: A

• Question 74:

  In the exhibit, VM1 is part of the same VXLAN segment as VM3.

  

  Which type of message will VTEP B initially send to the RP so that VM3 can communicate with VM1?

  A. PIM join

  B. IGMP Join (*, G)

  C. IGMP Join (S,G)

  D. PIM register message

  Correct Answer: D

• Question 75:

  Devices spine1 and spine have been configured as distributed Layer 3 gateways in the VXLAN topology, and devices leaf1 and leaf3 have been configured as layer 2 gateways. Device host must be able to communicate with device host?

  

  Which two statements are true? (Choose two.)

  A. An IRB interface must be configured on device leaf1 and leaf2.

  B. An IRB interface must be configured on devices spine1 and spine2.

  C. Traffic from host1 to host2 will transmit the VXLAN tunnel from leaf1 to leaf3.

  D. Traffic from host1 to host will transit a VXLAN tunnel to spine or spine2 then a VXLAN from spine1 or spine2 to leaf 3.

  Correct Answer: BC

• Question 76:

  A VXLAN adds 50 to 54 bytes of extra header information to an Ethernet frame. In this scenario, how would you accommodate this increased?

  A. Increase the MTU on the Physical interface connected to the VXLAN network.

  B. Increase the MTU on the VTEP interface connected to the VXLAN network

  C. Only use switches as VTEPs.

  D. Decrease the number VXLANs used

  Correct Answer: A

• Question 77:

  You are asked to manage multicast traffic in the EVPN-VXLAN environment. You must ensure that multicast traffic is delivered only to the leaf device with interested receivers. In this scenario, which feature is required on leaf devices to accomplish this task?

  A. PIM

  B. IGMP snooping

  C. MSDP

  D. DVMRP

  Correct Answer: B

• Question 78:

  Referring to the exhibit, which two statements are correct? (Choose two.)

  

  A. The local leaf is using the 192.168.100.102 IP address as the local anchor point of the VTEP tunnel.

  B. The remote leaf is using the 192.168.100.102 IP address as the local anchor point of the VTEP tunnel.

  C. The remote leaf is using the 192.168.100.101 IP address as the local anchor point of the VTEP tunnel.

  D. The local leaf is using the 192.168.100.101 IP address as the local anchor point of the VTEP tunnel.

  Correct Answer: AC

• Question 79:

  A company wants to expect their hosting business and is seeking solutions to supported multiple tenants. Each tenant should be able to configure their own logical interfaces. Also, based on customer needs, all routing features must be supported.

  What will satisfy the customer's requirements?

  A. Bridge domains

  B. Tenant systems

  C. Logical systems

  D. Routing instances

  Correct Answer: C

• Question 80:

  You choose the EBGP design shown in the exhibit as your IP fabric design. You must ensure that both routes received by the spine nodes will be used for ECMP forwarding.

  

  Which BGP parameter would need to be added to the EBGP configuration of the spine nodes to achieve this goal?

  A. multipath

  B. multihop

  C. add-path

  D. multipath multiple-as

  Correct Answer: D
