350-601 Single FI upgrade Practice Question
A company recently deployed Cisco UCS B-Series blades with a single Fabric Interconnect. During a maintenance window, the Fabric Interconnect must be upgraded. Which action ensures minimal disruption to running workloads?
⚠ Common exam trap
A common trap is to assume that disassociating service profiles allows a non-disruptive upgrade. In reality, for a single FI, this causes loss of connectivity and service disruption. The correct procedure requires a maintenance window with blade shutdown.

Correct answer & explanation
✓
Shut down all blades gracefully, upgrade the Fabric Interconnect, then power on blades.
In a single Fabric Interconnect domain, there is no redundancy. Disassociating service profiles while blades are running causes loss of management connectivity and potential network disruption. The only way to perform the upgrade without risking data corruption is to schedule a maintenance window: gracefully shut down all blades, upgrade the Fabric Interconnect, then power on the blades. This ensures workloads are safely stopped and restarted after the upgrade.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disassociate service profiles from blades, upgrade the Fabric Interconnect, then re-associate the service profiles.
Why it's wrong here
Disassociating service profiles while blades are running will cause the blades to lose their logical configuration and network connectivity, resulting in service disruption. This is not a non-disruptive method.
- ✗
Use the UCS Manager GUI to migrate all service profiles to a second Fabric Interconnect.
Why it's wrong here
There is only one Fabric Interconnect, so migrating to a second one is not possible. This option is invalid.
- ✓
Shut down all blades gracefully, upgrade the Fabric Interconnect, then power on blades.
Why this is correct
Gracefully shutting down the blades ensures workloads are safely stopped. After the FI upgrade, powering on the blades restores service. This is the correct procedure for a single FI.
- ✗
Change the boot order of blades to boot from NFS image, then upgrade FI.
Why it's wrong here
Changing the boot order to boot from NFS image is unrelated to the FI upgrade and does not address the issue.
