350-601 Compute Practice Question
A data center administrator is troubleshooting slow storage performance on a UCS B-Series blade server. The server is connected to a Cisco UCS 6300 Series Fabric Interconnect and uses local SAS drives. The administrator checks the UCS Manager and sees that the storage adapter has a driver version that is not recommended. What is the most likely impact of using a non-recommended driver version?
⚠ Common exam trap
Cisco often tests the distinction between a 'non-recommended' driver (which causes performance or stability issues) versus a 'non-supported' driver (which could cause boot failure or complete non-functionality), tempting candidates to overestimate the impact.

Correct answer & explanation
✓
Degraded storage performance or instability
Using a non-recommended driver version for the storage adapter in a UCS B-Series blade server can lead to degraded storage performance or system instability. Cisco validates specific driver versions for compatibility with the UCS 6300 Series Fabric Interconnect and local SAS drives; deviations may cause suboptimal I/O handling, increased latency, or unexpected errors. This is a common issue in compute environments where driver- firmware mismatches affect storage throughput.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Degraded storage performance or instability
Why this is correct
Non-recommended drivers are not validated and can cause performance issues or system instability.
- ✗
Loss of redundancy on the fabric interconnect
Why it's wrong here
Driver version does not affect fabric interconnect redundancy.
- ✗
Inability to boot the server
Why it's wrong here
A non-recommended driver may still allow boot, but performance could suffer.
- ✗
Increased security vulnerabilities
Why it's wrong here
Security vulnerabilities are possible but not the most likely impact of a non-recommended driver.
