1Z0-1127-25 Using OCI Generative AI Service Practice Question
Which THREE steps are necessary to secure access to the OCI Generative AI inference API in a production environment?
⚠ Common exam trap
Oracle often tests the distinction between network-layer controls (NSGs, private endpoints) and data-layer controls (encryption, masking), expecting candidates to recognize that securing API access requires network and IAM controls, not data protection features.
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
✓
Configure network security groups to allow only trusted source IPs to the inference endpoint.
Network security groups (NSGs) allow you to restrict inbound traffic to the Generative AI inference endpoint to only trusted source IP addresses, reducing the attack surface. In a production environment, this is a fundamental network-layer security control to prevent unauthorized access to the API.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable encryption with OCI Vault keys for all inference data.
Why it's wrong here
Encryption protects data at rest but does not control access.
- ✓
Configure network security groups to allow only trusted source IPs to the inference endpoint.
Why this is correct
NSGs provide network-level security.
- ✓
Create IAM policies that grant the 'use' verb on generative-ai-family resources.
Why this is correct
IAM policies are fundamental for authorization.
- ✓
Use private endpoints to access the Generative AI service from a VCN.
Why this is correct
Private endpoints avoid public internet exposure.
- ✗
Apply data masking policies to obfuscate sensitive information in prompts.
Why it's wrong here
Data masking is a post-processing step, not an access control mechanism.
