- A
On-demand token-based inference
Why wrong: On-demand uses shared infrastructure and does not guarantee low latency or isolation.
- B
A dedicated AI cluster with provisioned model units
A dedicated cluster provides isolated compute for low-latency, dedicated inference of custom fine-tuned models.
- C
Shared infrastructure with reserved capacity
Why wrong: Shared infrastructure is multi-tenant and may not meet strict latency SLAs or isolation requirements.
- D
OCI Functions using the GenAI SDK
Why wrong: OCI Functions is a serverless compute service, not a GenAI inference infrastructure option.

1Z0-1127 OCI Generative AI Service Practice Question
This 1Z0-1127 practice question tests your understanding of oci generative ai service. 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 organization is deploying a custom fine-tuned model for a real-time fraud detection application. The model must respond within 200ms and cannot share infrastructure with other customers. Which OCI GenAI infrastructure option should they choose?
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
✓
A dedicated AI cluster with provisioned model units
Option B is correct because a dedicated AI cluster with provisioned model units ensures exclusive infrastructure, meeting the requirement to not share resources with other customers. This option also provides predictable, low-latency inference (under 200ms) by allocating dedicated compute capacity for the fine-tuned model, which is critical for real-time fraud detection.
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.
- ✗
On-demand token-based inference
Why it's wrong here
On-demand uses shared infrastructure and does not guarantee low latency or isolation.
- ✓
A dedicated AI cluster with provisioned model units
Why this is correct
A dedicated cluster provides isolated compute for low-latency, dedicated inference of custom fine-tuned models.

- ✗
Shared infrastructure with reserved capacity
Why it's wrong here
Shared infrastructure is multi-tenant and may not meet strict latency SLAs or isolation requirements.
- ✗
OCI Functions using the GenAI SDK
Why it's wrong here
OCI Functions is a serverless compute service, not a GenAI inference infrastructure option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between 'reserved capacity' (which still shares infrastructure) and 'dedicated infrastructure' (which provides full isolation), leading candidates to mistakenly choose shared infrastructure with reserved capacity.
Detailed technical explanation
How to think about this question
Provisioned model units in OCI GenAI allocate a fixed number of GPU nodes (e.g., NVIDIA A100 or H100) exclusively to a customer's fine-tuned model, ensuring consistent throughput and latency. This is analogous to provisioned throughput in other AI services, where the model is loaded into GPU memory continuously, avoiding cold start delays. In fraud detection, even a 50ms variance can allow fraudulent transactions to slip through, making dedicated capacity essential for meeting strict SLAs.
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.
