1Z0-1127-25 Deploying and Managing Generative AI on OCI Practice Question
A company deploys a fine-tuned model on an OCI Generative AI dedicated AI cluster. After deployment, they observe high latency during peak hours. The cluster has only one replica. Which action would most effectively reduce latency without increasing cost unnecessarily?
⚠ Common exam trap
Oracle often tests the misconception that more replicas always reduce latency, but the trap here is that candidates may choose Option A (10 replicas) without considering cost efficiency, while the correct answer requires balancing performance with cost constraints via auto-scaling.

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
✓
Enable auto-scaling with a maximum of 3 replicas.
Enabling auto-scaling with a maximum of 3 replicas (Option B) is the most effective action because it dynamically adds replicas during peak hours to handle increased load, reducing latency, while limiting the maximum to 3 prevents unnecessary cost overruns. This balances performance and cost, unlike a fixed large replica count or switching models, which either wastes resources or fails to address the root cause of insufficient compute capacity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the number of replicas to 10.
Why it's wrong here
Too many replicas increase cost unnecessarily without proportional benefit.
- ✓
Enable auto-scaling with a maximum of 3 replicas.
Why this is correct
Auto-scaling adjusts to demand; a max of 3 provides headroom without waste.
- ✗
Switch to a larger base model.
Why it's wrong here
Larger models typically have higher latency, making the problem worse.
- ✗
Move to a serverless deployment model.
Why it's wrong here
Serverless may introduce cold starts and not guarantee low latency.
