As an NVIDIA-Certified Associate, which physical layer management practices should you implement to prevent such issues in the future?
- A
Use labeled and color-coded cables for organized connections.
- B
Ensure all cables are of the shortest length possible, even if they are tightly stretched.
- C
Implement cable trays and Velcro straps to secure cables neatly.
- D
Regularly inspect and test cables for wear and damage.
- E
Place high-voltage power cables and data cables in the same conduit to minimize space usage.
Show answer and explanation
Correct answers: A, C, D
Explanation
Proper physical layer management ensures the reliability and performance of AI infrastructure. Labeling and organizing cables, securing them with trays and straps, and conducting regular inspections are essential practices for preventing connectivity issues, minimizing physical damage, and maintaining operational efficiency.
- A. Correct.
Color-coding and labeling help reduce human errors during troubleshooting and maintenance, ensuring clear identification of cables in complex setups.
- B. Incorrect.
While short cables may reduce slack, tightly stretched cables are prone to damage and disconnections due to tension. This is not a best practice.
- C. Correct.
Using cable trays and Velcro straps helps maintain an organized and secure cable layout, minimizing the risk of physical damage and ensuring proper airflow.
- D. Correct.
Regular inspections and testing are crucial to identify worn-out or damaged cables early, avoiding unexpected connectivity issues.
- E. Incorrect.
Placing power and data cables together can lead to electromagnetic interference, affecting the performance of data transmission. This is not recommended.
