NCP-AII Question 91
Select 4You are tasked with deploying a new NVIDIA DGX server in your data center. Before installation, you need to ensure that the power and cooling requirements for the server are met. Which actions should you take to validate the power and cooling for the system?
- A
Verify that the power supply can deliver sufficient wattage to support the server under peak load.
- B
Ensure the data center cooling system can maintain an ambient temperature below the server's maximum operating temperature.
- C
Install the server without checking the power and cooling to test the system under real-world conditions.
- D
Check that the power distribution unit (PDU) has adequate capacity and appropriate connectors for the server.
- E
Confirm that the airflow in the server rack is optimized for heat dissipation, such as front-to-back airflow alignment.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Validating power and cooling is a crucial step before installing any high-performance system like an NVIDIA DGX server. This process involves checking that the power infrastructure can handle the server's load, the cooling system can maintain appropriate temperatures, and the physical environment (e.g., rack airflow) supports optimal operation. Skipping these steps can lead to hardware instability, performance degradation, or even permanent damage.
- A. Correct.
Ensuring the power supply can deliver sufficient wattage is critical to prevent power failures or system instability during peak usage.
- B. Correct.
Maintaining an appropriate ambient temperature is necessary to keep the server within its thermal operating range and prevent overheating.
- C. Incorrect.
Skipping power and cooling validation before installation is risky and may lead to hardware damage or operational failures.
- D. Correct.
Ensuring the PDU has the required capacity and connectors is essential to provide stable and compatible power to the server.
- E. Correct.
Optimizing airflow in the rack helps prevent heat buildup and ensures efficient cooling for the server.
