  • A: Configure the NVE interfaces to be Up on both switches.
  • B: Set a different distributed gateway virtual MAC address.
  • C: Set a different secondary IP addresses on NVE source-interface.
  • D: Configure the same VNI to multicast group maping.
  • E: Set a different primary IP addresses on NVE source-interface.



Question 2
A mission-critical server is connected to site A. Connectivity to this server is lost from site B because the MAC route is missing in the OTV VDC of the Nexus 7000 in site B due to MAC aging. Which action allows the flooding of the unknown unicast MAC on the Nexus 7000 in the OTV VDC?

  • A: Use route-map to advertise this MAC statically and redistribute with ISIS.
  • B: Unknown unicast flooding is not allowed.
  • C: Use the otv flood mac <> command to selectively flood traffic for a given MAC.
  • D: Use the otv isis bfd <> command to configure BFD protocol.



Question 3
 

Refer to the exhibit. After a failover occurs, which two actions must be performed on Switch-B to manually preempt the operational primary role back to Switch-A? (Choose two.) 

  • A: Configure the local vPC role priority to have a lower value than Switch-A. 
  • B: Configure the local vPC role priority to have a higher value than Switch-A.
  • C: Disable and then re-enable the vPC peer-keepalive link.
  • D: Configure the local vPC role priority to have the same value as Switch-A.
  • E: Disable and then re-enable the vPC peer link.



Question 4
 

Refer to the exhibit. An OSPF adjacency between Router-A and Router-B cannot reach the FULL state. Which action resolves the issue?

  • A: Adjust the MTU on Router-A to 1600.
  • B: Disable the check of the MTU value.
  • C: Set the OSPF media type to point-to-point.
  • D: Adjust the MTU on Router-B to 1604.



Question 5
The Cisco Nexus switch is connected to a peer switch that is not running Cisco NX-OS. The switches are connected using port channel and are experiencing packet loss. Which action should be performed on the Cisco Nexus switch ports to resolve this issue?

  • A: Turn on lacp suspend-individual.
  • B: Turn on lacp graceful-convergence. 
  • C: Turn off lacp graceful-convergence.
  • D: Turn off lacp suspend-individual.



Question 6
 

Refer to the exhibit. The HSRP configuration in the exhibit fails to function. Which action resolves this issue?

  • A: Enable IP redirects.
  • B: Set the MTU to 1500 bytes.
  • C: Configure HSRP version 2.
  • D: Configure the same HSRP group on both devices.



Question 7
 

Refer to the exhibit. The HSRP instance on both switches is showing as active. Which action resolves the issue?

  • A: Configure the HSRP timers to be the same.
  • B: Allow VLAN 100 between the switches.
  • C: Configure the IP address of N9K-B on the same subnet as N9K-A.
  • D: Configure preempt on only one of the switches.



Question 8
An engineer is troubleshooting a fabric discovery failure. Which two requirements must an engineer verify about switch connectivity to solve the problem? (Choose two.)

  • A: A Cisco APIC must be attached to a spine node only.
  • B: A Cisco APIC must be attached to leaf nodes.
  • C: Spine nodes must connect to other spine nodes.
  • D: A Cisco APIC must be dual-attached to two separate spine nodes.
  • E: Leaf nodes must connect to spine nodes only. 



Question 9
 

Refer to the exhibit. A network engineer has connected the Nexus switch management port to the Internet using DHCP to allow the Guest shell running on the switch to download Python packages. The engineer can ping google.com successfully from the Nexus switch, but the Guest shell failed to download any Python packages. Which action resolves the problem?

  • A: Update the Python packages on the Cisco Nexus switch directly.
  • B: Manually configure DNS in the Guest shell, even if it is claimed on the Cisco Nexus switch through DHCP.
  • C: Manually configure NTP in the Guest shell.
  • D: Connect Guest shell to data plane interfaces to be able to connect to the networks outside the Cisco Nexus switch.



Question 10
 

Refer to the exhibit. vPC between switch1 and switch2 is not working. Which two actions are needed to fix the problem? (Choose two.)

  • A: Match vPC domain ID between the two devices.
  • B: Configure IP address on the interface.
  • C: Activate VLANs on the vPC.
