You are implementing a UCS B-Series environment for a customer with both bare-metal and virtualized servers.
The bare-metal servers require two vNICs and two vHBAs. Administrators of virtualized servers will be utilizing VN-Link technology.
Which adapter should be recommended?
A. Cisco UCS M81KR
B. Cisco UCS M72KR-Q
C. Cisco UCS M71KR-E
D. Cisco UCS P81E
E. Cisco UCS M51KR-B
Correct Answer: A

Explanation:
M81KR (supports many adapters and VN-LINK)

M72KR-Q (supports only one adapter, does not support VN-LINK)

M71KR-E (supports only one adapter, does not support VN-LINK)

P81E (supports many adapters, does not support VN-LINK)

M51KR-B (this is not a converged network adapter CNA, and does not support vHBAs) https://www.cisco.com/c/dam/en/us/products/collateral/servers-unifiedcomputing/ucs-b-seriesblade- servers/spec_sheet_c17-644236.pdf
Answer A. is correct (M81KR), as we are talking about B-series.
However, just a note:
P81E does support VN-LINK in hardware (VM-FEX), and multiple vNICs/vHBAs too, but for C-series.

“The M81KR and P81E are the first implementation of Cisco VM-FEX technology in hardware.
VM-FEX collapses virtual and physical networking into a single, easy-to-manage networking domain.”
