1Z0-1127-25 Deploying and Managing Generative AI on OCI Practice Question
A company is deploying a generative AI model on OCI for an internal application that must comply with strict security policies. The model will be accessed by a limited group of users. Which three actions should the administrator take to ensure security? (Choose three.)
⚠ Common exam trap
Candidates often think exposing the endpoint to the internet is acceptable if IAM policies are used, but network isolation (private subnet) is a separate and mandatory layer of defense that cannot be replaced by IAM alone.
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
✓
Deploy the model in a private VCN subnet
Deploying the model in a private VCN subnet ensures that the model endpoint is not exposed to the internet, which is a fundamental security requirement for compliance with strict security policies. By placing the model in a private subnet, all traffic must traverse through a bastion host, VPN, or FastConnect, providing network isolation and reducing the attack surface. This aligns with OCI's shared responsibility model where the customer controls network security.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Expose the model endpoint to the internet for ease of access
Why it's wrong here
Public exposure increases security risk and is not recommended for internal apps.
- ✓
Deploy the model in a private VCN subnet
Why this is correct
A private subnet ensures the endpoint is not publicly accessible.
- ✓
Use IAM policies to restrict model endpoint access to specific users
Why this is correct
IAM policies provide fine-grained access control.
- ✗
Disable audit logging to minimize storage costs
Why it's wrong here
Audit logging is essential for security compliance and monitoring.
- ✓
Store model authentication keys in OCI Vault
Why this is correct
OCI Vault securely stores and manages secrets like API keys.
