Grant 'use' on oci-generative-ai-family for Embedding Access
This 1Z0-1127 practice question tests your understanding of building llm applications with rag and vector search. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An IAM policy is shown in the exhibit. A user reports that they cannot call the OCI GenAI embedding API, but they can use OCI AI Language. Which policy statement is missing to allow embedding API access?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy needs 'use' action on 'oci-generative-ai-family'
The correct answer is A because the user can already use OCI AI Language, indicating that the existing policy grants access to the 'oci-ai-language-family' resource. To also allow access to the OCI GenAI embedding API, the policy must include a 'use' verb on the 'oci-generative-ai-family' resource type. The 'use' verb is the minimum required permission for invoking inference operations like embedding, while 'manage' would be excessive and 'inspect' is insufficient for API calls.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The policy needs 'use' action on 'oci-generative-ai-family'
Why this is correct
Missing 'use' permission for GenAI.

✗
The policy needs 'inspect' on 'oci-generative-ai-endpoint'
Why it's wrong here
Endpoint-level permission is not needed if family permission is granted.
✗
The policy needs 'manage' action on 'oci-generative-ai-family'
Why it's wrong here
'manage' is excessive; 'use' is sufficient.
✗
The policy needs 'inspect' on 'oci-ai-language-family'
Why it's wrong here
Already has 'use' on AI Language.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle OCI GenAI tests the distinction between 'use', 'inspect', and 'manage' verbs. The trap is that candidates may choose 'manage' thinking it covers all actions, or 'inspect' assuming read access suffices, but only 'use' allows invoking the embedding API.
Detailed technical explanation
How to think about this question
In OCI IAM, resource families like 'oci-generative-ai-family' aggregate related resource types (e.g., endpoints, models). The 'use' verb on a family allows invoking inference operations (e.g., embed, chat) without granting management capabilities. Under the hood, the embedding API call is an HTTP POST to a specific endpoint, and IAM evaluates the policy's 'use' action against the resource type 'oci-generative-ai-endpoint' within the family. A real-world scenario: a developer building a RAG application needs only 'use' on the family to call the embedding model, while a DevOps engineer managing model deployments would need 'manage'.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-1127 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
