NCP-AIO Troubleshooting and Optimization Practice Question
Exhibit
nvidia-smi -q -d PERFORMANCE Performance State : P0 Clocks Throttle Reasons : Active Clocks Throttle Reason Sw Power Cap : Active
Refer to the exhibit. What is the most effective way to resolve this specific throttling condition?
⚠ Common exam trap
Candidates often assume the issue is a software bug or driver failure. They overlook the possibility that the GPU is simply hitting a configured power limit enforced by the administrator.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the power limit for the GPU using nvidia-smi.
The exhibit indicates that the GPU is hitting a software-defined power cap. This is a common situation when a node is configured with a restricted power limit to manage rack-level power consumption. Adjusting the power limit using nvidia-smi ensures the GPU can access the necessary power to reach higher clock frequencies, which is essential for maximizing performance in compute-intensive deep learning tasks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Update the GPU firmware to the latest release.
Why it's wrong here
Firmware updates do not change the software power cap settings. The cap is a configuration parameter applied by the system administrator to maintain power envelope compliance, and updating firmware will not override this user-defined restriction on the GPU's power consumption.
- ✗
Reinstall the NVIDIA display driver.
Why it's wrong here
Driver issues do not cause active software power caps. These caps are persistent configurations set via the driver's management tools. Reinstalling the driver will reset the environment but will not remove the power limitation unless it was an accidental configuration change that needs to be reverted.
- ✓
Increase the power limit for the GPU using nvidia-smi.
Why this is correct
The 'Sw Power Cap' throttle reason explicitly states that the software power limit is currently restricting the GPU performance. Increasing the power limit via the nvidia-smi tool allows the driver to permit higher clock speeds, effectively removing this constraint and enabling the GPU to perform at full capacity.
- ✗
Replace the power distribution unit (PDU) in the rack.
Why it's wrong here
While a bad PDU can cause power issues, the specific reason shown is 'Sw Power Cap,' which is a software setting. Hardware replacement is unnecessary and does not resolve the software-enforced limit that is explicitly being reported by the GPU driver as the cause of the throttling.
