Cable and transceiver installation: Practice Questions — System and Server Bring-up (NVIDIA-Certified Professional: AI Infrastructure)

Cable and Transceiver Installation: Practice Questions for NVIDIA-Certified Professional: AI Infrastructure

This set of multiple-choice questions is designed to help candidates prepare for the System and Server Bring-up section of the NVIDIA-Certified Professional: AI Infrastructure exam, focusing specifically on cable and transceiver installation tasks.

1. Which of the following is the primary reason for using QSFP (Quad Small Form-factor Pluggable) transceivers in NVIDIA GPU-based AI servers?

   • A. To provide power delivery to GPUs
   • B. To enable high-speed data transfer between server components
   • C. To cool the server chassis efficiently
   • D. To manage firmware upgrades remotely

   Correct answer: B

   Explanation: QSFP transceivers are used to facilitate high-speed data communication, essential for AI workloads requiring rapid data transfer between GPUs and network fabrics.

2. During cable installation in an AI infrastructure server, what is the recommended practice to avoid signal degradation?

   • A. Use cables longer than 10 meters for flexibility
   • B. Avoid bending cables sharply or exceeding minimum bend radius
   • C. Connect cables while the server is powered on to verify connectivity immediately
   • D. Use any available cable type regardless of specifications

   Correct answer: B

   Explanation: Maintaining the minimum bend radius prevents damage to cable fibers or copper conductors, preserving signal integrity.

3. What is the purpose of verifying transceiver compatibility before installation in an NVIDIA AI server?

   • A. To ensure the transceiver supports the required data rate and protocol
   • B. To confirm the transceiver provides additional cooling
   • C. To enable automatic power management on the server
   • D. To allow firmware upgrades to be skipped

   Correct answer: A

   Explanation: Compatibility ensures the transceiver matches the server’s networking requirements, avoiding connectivity issues or performance bottlenecks.

4. Which tool or method is best suited for testing cable continuity and signal quality after installation in an AI infrastructure environment?

   • A. Multimeter
   • B. Optical Time-Domain Reflectometer (OTDR)
   • C. Power supply tester
   • D. Firmware update utility

   Correct answer: B

   Explanation: An OTDR is used to test fiber optic cables for faults, breaks, and signal loss, ensuring proper installation.

5. When installing cables and transceivers in a GPU-based server, what is the recommended sequence to minimize downtime and errors?

   • A. Install all cables first, then insert all transceivers simultaneously
   • B. Insert transceivers first, then connect cables one at a time, verifying each connection
   • C. Connect cables and transceivers randomly to save time
   • D. Skip verification to speed up deployment

   Correct answer: B

   Explanation: Inserting transceivers first and then connecting cables one by one with verification reduces installation errors and facilitates troubleshooting.

6. What is a common cause of transceiver failure during installation in AI infrastructure servers?

   • A. Using transceivers from different manufacturers
   • B. Static discharge damaging sensitive components
   • C. Installing transceivers in the wrong server rack
   • D. Over-tightening cable ties

   Correct answer: B

   Explanation: Electrostatic discharge (ESD) can damage transceiver electronics; proper grounding and ESD precautions are essential during handling.

7. Which of the following is an essential step after installing cables and transceivers in an NVIDIA AI server?

   • A. Immediately powering off the server
   • B. Running diagnostic tests to validate connectivity and performance
   • C. Removing all labels from cables for neatness
   • D. Disconnecting cables to verify physical robustness

   Correct answer: B

   Explanation: Running diagnostics confirms that the installation is successful and that the system components communicate correctly.
