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.
Refer to the exhibit. A user runs this command and gets an error: 'InvalidParameter: unit-shape 'GPU.1' is not supported in this region. Supported shapes: GPU.2, GPU.4'. What should the user do?
Use unit-shape GPU.2
GPU.2 is explicitly supported in the error message.
Increase unit count
Why wrong: Unit count does not affect shape support.
Change compartment
Why wrong: Compartment is irrelevant to shape availability.
Use a different region
Why wrong: Could work but not the most direct fix; the current region may be fine with a supported shape.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use unit-shape GPU.2
The error message explicitly states that 'GPU.1' is not supported in the current region and lists 'GPU.2' and 'GPU.4' as supported shapes. Option A correctly instructs the user to use a supported shape, such as GPU.2, which resolves the invalid parameter error without changing other configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Use unit-shape GPU.2
Why this is correct
GPU.2 is explicitly supported in the error message.

Increase unit count
Why it's wrong here
Unit count does not affect shape support.
Change compartment
Why it's wrong here
Compartment is irrelevant to shape availability.
Use a different region
Why it's wrong here
Could work but not the most direct fix; the current region may be fine with a supported shape.
Common exam traps
Oracle OCI candidates often mistakenly believe that increasing unit count or changing compartments can resolve shape-related errors, but the error is strictly about the shape name not being supported in that region.
Detailed technical explanation
OCI Generative AI service shapes like GPU.1, GPU.2, and GPU.4 refer to specific GPU configurations (e.g., NVIDIA A100 or similar) with varying memory and compute capabilities. Shape availability is determined by regional capacity and service limits; for example, GPU.1 might be deprecated or not deployed in certain regions due to hardware refresh cycles. The user should verify the region's shape catalog via the OCI CLI or console before provisioning to avoid such errors.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
