An engineer installed a new Nexus switch with the mgm0 interface in vrf management. Connectivity to the rest of the network needs to be tested from the guest shell of the NX-OS. Which command tests connectivity from the guest shell of the NX-OS?
[guestshell@guestshell ~]$ dohost ''ping vrf management 173.37.145.84''
[guestshell@guestshell ~]$ chvrf management ping 173.37.145.84
[guestshell@guestshell ~$ ping 173.37.145.84 vrf management
[guestshell@guestshell ~]$ iping vrf management ip 173.37.145.84

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?
Commit the active database with the port-security database copy vsan 1 command
Disable auto learn in VSAN 1 with the no port-security auto-learn vsan 1 command
Disable CFS distribution with the no port-security distribute vsan 1 command
Commit the changes with the port-security commit copy vsan 1 command

A Fibre Channel interface on a Cisco Nexus 5000 Series Switch receives bit errors, and the switch disables the interface. A temporary workaround must be implemented before the root cause is identified. Which action prevents this issue from reoccurring?
Verify that the SFPs are supported.
Change the SFP to operate at 4 Gbps instead of 2 Gbps.
Run the shutdown and then no shutdown commands on the interface.
Run the switchport ignore bit-errors command on the interface.

A Cisco APIC must be attached to leaf nodes.
Spine nodes must connect to other spine nodes.
A Cisco APIC must be dual-attached to two separate spine nodes.
Leaf nodes must connect to spine nodes only.
