Designing Cisco Data Center Infrastructure (DCID) — Question 126

An engineer is implementing a Cisco UCS environment The requirements for the solution are for the MAC addresses to be learned only on the server-facing ports. The use of the Spanning Tree Protocol must be avoided. Also, the engineer must have deterministic traffic handling from blades to uplink ports.

Which two settings must be selected to meet these requirements? (Choose two.)

Answer options

• A. end-host mode
• B. dynamic pinning
• C. NPIV mode
• D. static pinning
• E. switching mode

Correct answer: A, D

Explanation

Selecting 'end-host mode' ensures that MAC addresses are only learned on server-facing ports, fulfilling the requirement to avoid Spanning Tree Protocol. 'Static pinning' provides deterministic traffic handling from blades to uplink ports, which is essential for this setup. The other options do not meet both criteria as effectively as A and D.
