- A
Enable the generative AI service in the console.
Why wrong: Enabling in the console is part of subscription, not a separate step.
- B
Set up a VCN with service gateway.
Why wrong: Networking is optional; the service works via public endpoint.
- C
Create a dynamic group.
Why wrong: Dynamic groups are used for resources, not required for enabling the service.
- D
Subscribe to the service in the tenancy.
Subscription enables the service for the tenancy.
- E
Create a policy to allow access.
Policies are required to grant users or groups access to the service.

1Z0-1127 Using OCI Generative AI Service Practice Question
This 1Z0-1127 practice question tests your understanding of using oci generative ai service. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO configuration steps are required to enable OCI Generative AI service in a tenancy? (Select two.)
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
✓
Subscribe to the service in the tenancy.
Both options D and E are correct. To use OCI Generative AI service, you must first subscribe to the service at the tenancy level (option D) and then create an IAM policy to grant users or groups access to the service (option E). Simply enabling the service in the console is not a step; the service is enabled through subscription. Networking components like a VCN or service gateway are not prerequisites, and dynamic groups are not required for basic access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the misconception that you need to 'enable' a service in the console or configure networking components like a service gateway, when in fact the required steps are subscription and IAM policy creation.
Detailed technical explanation
How to think about this question
Under the hood, OCI Generative AI service uses IAM policies to control access at the resource level, where you define which users or groups can invoke models or manage endpoints. The subscription step registers the tenancy with the service's backend, enabling billing and resource provisioning. In a real-world scenario, an administrator would first subscribe, then create a policy like 'Allow group DataScientists to use generative-ai-family in tenancy' to grant access.
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.
