Which three selections represent implementations of Cisco VN-Link technology? (Choose three.)

A.
Cisco Nexus 1000V

B.
Cisco Nexus 2000 FEX

C.
Cisco VM-FEX

D.
VMware PTS

E.
vMotion

Explanation:
The VM is powered on and resides on the ESX Host 1 with all the information stored on the shared
storage.
The VM was connected to the PODy (where y is the number of your POD) PTS VDS by associating it
to port group VLAN61 that was created on the Cisco Nexus 5548 device. The VM has been connected
to the vPC system automatically using a VN-Link in the hardware in PTS mode or in VM-FEX mode.
The VEM bits are used in PTS mode to connect the VM VNIC to the VMNIC interface.
In this case, the VMNIC interface is not a real VMNIC but a dynamic VNIC that is presented as an
interface to the ESX OS. The dynamic VNIC is enabled when the Cisco UCS VIC creates and configures
the VNIC parameters inherited from port group VLAN61.
