It is possible to run multiple VEMs per hypervisor host.
Which statement is true about FCIP configuration on Cisco MDS switches?

When upgrading the Cisco UCS to a new firmware bundle, in what order should you perform the upgrade?
Interface cards, CIMC Controller, IO Modules, Cisco UCS Manager, Fabric Interconnects
Which two options describe virtualized multi-tenancy? (Choose two.)
shares a common infrastructure between tenants
data centers using virtualization technologies to separate tenants
Which two VLANs does the VSM use to communicate with the VEM modules when using the default transport mode? (Choose two.)
A VSM is actually a virtual machine that requires how many vNICs for functioning?
Which two statements are true about LUNs in SCSI terminology? (Choose two.)
A LUN represents a logical unit number.
A LUN represents an individually addressable (logical) SCSI device that is part of a physical SCSI device (target).
In Cisco UCS Manager, under the LAN tab, which subcategory should you select to configure a vNIC template?
In a Cisco Nexus 5000 switch, each system class has an associated IEEE 802.1p CoS value that is assigned by default or configured on the system class. If you enable PFC, the switch sends the no-drop CoS values to the adapter, which then applies PFC to these CoS values. What is the default CoS value for the FCoE system class?
Which two options describe what it means when the port channel interface has a status of (SD)? (Choose two.)
The port channel interface itself is administratively shut down.
No operational member interfaces can be channeled.
