- A
Allow group data-scientists to read generative-ai-family in compartment genai-dev
Why wrong: 'read' is too restrictive; they need to invoke models which requires 'use'.
- B
Allow group data-scientists to manage generative-ai-family in compartment genai-dev
Why wrong: 'manage' allows all operations including creating clusters.
- C
Allow group data-scientists to use generative-ai-family in compartment genai-dev where request.operation != 'CreateDedicatedAiCluster'
This grants use of most GenAI resources but excludes creating dedicated clusters via a condition.
- D
Allow group data-scientists to use generative-ai-models in compartment genai-dev
Why wrong: 'generative-ai-models' is not a valid resource family; the correct family is 'generative-ai-family'.

1Z0-1127 OCI Generative AI Service Practice Question
This 1Z0-1127 practice question tests your understanding of oci generative ai service. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 administrator wants to grant a group of data scientists permission to use OCI Generative AI resources in a specific compartment, but prevent them from creating Dedicated AI Clusters. Which IAM policy statement achieves this?
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
✓
Allow group data-scientists to use generative-ai-family in compartment genai-dev where request.operation != 'CreateDedicatedAiCluster'
Option C is correct because it uses the 'use' verb to grant the data scientists access to OCI Generative AI resources while adding a condition with 'request.operation != 'CreateDedicatedAiCluster'' to explicitly deny the ability to create Dedicated AI Clusters. In OCI IAM, the 'use' verb includes read and update capabilities but not create or delete, and the condition further restricts the specific create operation, aligning with the requirement to prevent cluster creation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Allow group data-scientists to use generative-ai-models in compartment genai-dev
Why it's wrong here
'generative-ai-models' is not a valid resource family; the correct family is 'generative-ai-family'.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'use' verb with 'manage' or 'read', or overlook the necessity of a condition to block a specific operation, assuming a broader verb like 'manage' can be restricted by a condition when it actually grants all permissions including create.
Detailed technical explanation
How to think about this question
OCI IAM policy conditions like 'request.operation' allow fine-grained access control by matching against specific API operations (e.g., 'CreateDedicatedAiCluster' corresponds to the POST /dedicatedAiClusters endpoint). The 'use' verb in OCI IAM maps to a set of permissions that include read and update but exclude create and delete, making it ideal for granting operational access without full management. In a real-world scenario, data scientists might need to run inference jobs on existing clusters but should be prevented from provisioning new clusters to control costs and resource allocation.
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 security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
