Refer to the exhibit. A team created this dedicated AI cluster. However, when they try to create a model deployment, the deployment fails with an error indicating insufficient public IPs. What change to the cluster configuration should they make?

⚠ Common exam trap

The trap here is that candidates might think the issue is a subnet IP shortage (Option C) or a scaling problem (Option B), when the real cause is a misconfigured public IP assignment flag that prevents the cluster from using available IPs.

Answer choices

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

✓

Change assignPublicIp to true.

The error indicates insufficient public IPs because the cluster's subnet does not have enough available public IP addresses. Setting `assignPublicIp` to `true` in the cluster configuration allows the cluster to automatically allocate public IPs from the subnet's pool, resolving the shortage. This is required for model deployments that need public endpoints.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
Change assignPublicIp to true.
Why this is correct
Correct: Enabling public IPs allows nodes to have public endpoints.
✗
Increase the nodeCount to 8.
Why it's wrong here
Incorrect: Adding nodes increases IP demand, making the problem worse.
✗
Attach a different subnet that has more available public IPs.
Why it's wrong here
Incorrect: This might help but does not address the assignPublicIp=false setting; the cluster still wouldn't use public IPs.
✗
Change the AI cluster shape to VM.GPU.A10.2.
Why it's wrong here
Incorrect: Shape change does not affect IP allocation.
