- B . Build a new service profile with the desired network configuration
- C . Add the disjoint Layer 2 VLANs to an existing vNIC rather than adding new vNICs
- D . Create a vNIC placement policy to avoid adapter renumbering
Refer to the exhibit.

- B . Change the name of one of the zones to match the other zone set.
- C . Set the distribute policy of the zone to full.
- D . Ensure that the zone members have different names.

- A . Match the OSPF area between the two devices.
- B . Configure the IP addresses of the interface in the same subnet.
- C . Change the OSPF area type to 2 on n7k-1.
- D . Set the same MTU values on both sides of the link.
DRAG DROP
A firmware upgrade on a fabric interconnect fails. A bootflash contains a valid image.
Drag and drop the recovery steps from the left onto the correct order on the right.

Cisco UCS Manager is being upgraded using the Auto Install feature, but the FSM fails.
Which action resolves the issue?
- A . Acknowledge the primary fabric interconnect.
- B . Remove the service pack from the subordinate fabric interconnect.
- C . Clear the startup version of the default infrastructure pack.
- D . Upgrade the firmware of the infrastructure firmware by using the force option.
Refer to the exhibit.
An engineer must strictly enforce the port security configuration database in the Fibre Channel fabric. A new device has been connected to the Fibre Channel storage interface that was configured for port security. The port security was enabled for the VSAN that the port belongs to. Despite the configuration, the rogue devices can log into the fabric.
Which action resolves the issue?
- A . Commit the active database with the port-security database copy vsan 1 command
- B . Disable auto learn in VSAN 1 with the no port-security auto-learn vsan 1 command
- C . Disable CFS distribution with the no port-security distribute vsan 1 command
- D . Commit the changes with the port-security commit copy vsan 1 command
Refer to the exhibit.
customer reports that all Intra-EPG isolation stopped working within a bare-metal tenant. Postman is running on a machine to get information from the APIC in case of orchestration failure.
Which action resolves the issue?
- A . Match encap="vlan-10" and primaryEncap="vlan-110"
- B . Modify the GET command to reference the valid path for the managed object
- C . Change pcEnfPref="unenforced" to pcEnfPref="enforced".
