350-601 Compute Practice Question
A data center administrator reports that traffic from a specific UCS server is not flowing through the expected Fabric Interconnect (FI) A. The pin group is configured, but traffic is still sent to FI B. What should the administrator check?
⚠ Common exam trap
Cisco often tests the subtle distinction between a pin group being configured and the vNIC's fabric ID being misaligned, leading candidates to assume the pin group is automatically applied without checking the vNIC-level fabric assignment.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure the vNIC's fabric ID is set to match the pin group's preferred fabric.
The pin group configuration determines which Fabric Interconnect a vNIC should use for upstream traffic. If the vNIC's fabric ID is not set to match the pin group's preferred fabric, the server will ignore the pin group and send traffic to the other FI. Option D is correct because the fabric ID mismatch causes the pin group to be ineffective, and verifying this alignment ensures traffic flows through the expected FI A.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Verify that the server is associated with the correct service profile.
Why it's wrong here
Association is correct if the server is online.
- ✗
Reboot the Fabric Interconnect.
Why it's wrong here
Rebooting may cause temporary outage but does not fix configuration issue.
- ✗
Check if the pin group is deleted.
Why it's wrong here
If deleted, there would be no pinning at all, but traffic would go to primary FI normally.
- ✓
Ensure the vNIC's fabric ID is set to match the pin group's preferred fabric.
Why this is correct
The vNIC must have the fabric ID set to force traffic to the desired FI.
