NCP-AIO Installation and Deployment Practice Question
Which utility is primarily used to monitor and manage NVIDIA GPU power, temperature, and usage statistics in real-time on a Linux-based deployment?
⚠ Common exam trap
Candidates frequently confuse nvidia-smi with higher-level management tools or cloud-native exporters like DCGM, overlooking its role as the foundational host-level CLI utility.

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
✓
nvidia-smi
nvidia-smi (NVIDIA System Management Interface) is the command-line utility used to interact with the NVIDIA driver for monitoring and managing GPU devices. It is the fundamental tool for AI ops teams to verify that GPUs are properly detected and performing within expected thermal and power envelopes during model training or inference tasks on DGX or workstation systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
top
Why it's wrong here
The top utility monitors CPU and system memory usage. While it provides an overview of system load, it does not have the capability to report on GPU-specific metrics such as SM utilization, memory bandwidth, or hardware-level power consumption, making it insufficient for NVIDIA-accelerated AI infrastructure monitoring.
- ✓
nvidia-smi
Why this is correct
This is the official utility for managing NVIDIA GPU devices. It provides comprehensive real-time data on GPU usage, memory allocation, power consumption, and thermal status. It also allows administrators to set performance limits and reset devices, which is essential for maintaining a healthy and performant AI cluster.
- ✗
htop
Why it's wrong here
htop is a graphical enhancement of the top command for monitoring CPU processes. Similar to top, it lacks the hooks into the NVIDIA driver necessary to provide insights into GPU performance or health, and it cannot display information related to GPU-specific tasks or hardware resource utilization.
- ✗
dmesg
Why it's wrong here
dmesg is used to view the kernel ring buffer logs. While it may show driver-related error messages during initialization, it is not a performance monitoring tool. It cannot provide the granular, real-time statistics required to manage the operational state of multiple GPUs in a training cluster.
