NCA-GENL Question 8
Select 3You are assisting in the deployment of a large language model (LLM) for a real-time customer support application. Under the supervision of a senior team member, you are tasked with evaluating the model's scalability and performance under varying user loads. Which of the following steps should you prioritize to ensure the model performs reliably during peak usage?
- A
Simulate different levels of concurrent user traffic and measure response times.
- B
Manually adjust the model's architecture to reduce computational complexity.
- C
Monitor GPU utilization and memory usage during stress tests.
- D
Perform latency tests only during non-peak hours to avoid user disruption.
- E
Use load balancing to distribute incoming requests across multiple instances of the model.
Show answer and explanation
Correct answers: A, C, E
Explanation
To evaluate the scalability, performance, and reliability of a deployed model, it is important to simulate real-world usage scenarios such as concurrent user traffic and monitor system metrics like GPU utilization. Additionally, implementing load balancing is essential to ensure the system handles increased traffic effectively. These practices collectively help identify potential bottlenecks and improve the system's ability to perform reliably under varying conditions.
- A. Correct.
Simulating different levels of concurrent user traffic and measuring response times is a key step in evaluating the scalability and performance of the model under real-world conditions.
- B. Incorrect.
Manually adjusting the model's architecture is not typically the responsibility of an associate-level team member and requires significant expertise beyond deployment and evaluation tasks.
- C. Correct.
Monitoring GPU utilization and memory usage during stress tests helps in identifying bottlenecks and ensuring the model performs reliably under load.
- D. Incorrect.
Performing latency tests only during non-peak hours is not a recommended practice as it does not simulate real-world peak usage scenarios, which are critical for evaluation.
- E. Correct.
Using load balancing to distribute incoming requests across multiple instances of the model ensures scalability and reliability during high traffic periods.
