Question 11

Refer to the exhibit. Sw1 and Sw2 are two Cisco Nexus 9000 Series Switches that run Cisco NX-OS. They are VTEPs in the same vPC domain. What occurs in this scenario?

  1. Sw1 drops all traffic because there is no (S, G) OIF list to encapsulate VXLAN multicast packets and send them out to the underlay network through the uplink interfaces.
  2. Sw1 performs the VXLAN multicast encapsulation and decapsulation for all traffic associated with the VXLAN VNIs.
  3. Sw1 and Sw2 perform the VXLAN multicast encapsulation and decapsulation for all traffic associated with the VXLAN VNIs, depending on the hashing.
  4. Sw2 does not send an IP PIM register to the rendezvous point for the multicast group of the VXLAN VNI.

Question 12

A customer configures HSRP between two data centers that are interconnected with OTV. The configuration succeeds, but traffic between two ESXi virtual hosts on the same site is routed suboptimally through the OTV overlay. Which two actions optimize the traffic? (Choose two.)

  1. Disable first-hop redundancy.
  2. Filter HSRP traffic by using a Layer 3 VACL on the OTV edge devices.
  3. Filter HSRP by using a Layer 2 MAC list on the ESXi vSwitch.
  4. Filter HSRP traffic by using a Layer 3 VACL on the ESXi vSwitch.
  5. Filter HSRP by using a Layer 2 MAC list on the OTV edge devices.

Question 13

An engineer removes a VMM domain from an endpoint group called "EPG-1", but the distributed port group fails to be deleted. Which action resolves the issue?

  1. Manually remove the port group.
  2. Migrate all virtual machines in the EPG-1 to different hypervisors.
  3. Remove the remaining EPGs from the VMM domain.
  4. Migrate all virtual machines in the EPG-1 to different port groups.

Question 14

Refer to the exhibit. HSRP adjacency fails to form between Nexus7K-1 and Nexus7K-2. Which action should be taken to solve the problem?

  1. Configure preempt on one of the switches in the HSRP group.
  2. Configure the same HSRP priority between the two switches.
  3. Configure the correct subnet mask on Nexus7K-1.
  4. Configure HSRP version 2 on Nexus7K-2.

Question 15

An engineer troubleshoots a packet flow from an access leaf to a spine. Which EVPN routes are expected on this connection?

  1. EVPN Type 1-5
  2. EVPN Type 0, 9, and 15
  3. EVPN Type 9-15
  4. EVPN Type 0 and 16
