Quick Answer
The correct choice is to use unit-shape GPU.2, as the error message explicitly confirms that GPU.1 is unsupported in the current region while GPU.2 is listed among the supported shapes. This error occurs because Oracle Cloud Infrastructure Generative AI dedicated clusters restrict certain unit-shape configurations based on regional hardware availability; the unit-shape parameter defines the GPU model and compute capacity allocated to the cluster, and each region maintains a specific set of supported shapes to ensure resource optimization. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this scenario tests your understanding of dedicated cluster provisioning constraints and the importance of reading error output precisely—a common trap is assuming you can change regions or increase unit count, but the fastest fix is simply selecting a supported shape from the error’s own list. Remember the memory tip: “When the shape is the snag, pick from the error’s bag.”
This 1Z0-1127 practice question tests your understanding of using 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.
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
Option B is correct because the error indicates GPU.1 is unsupported, and GPU.2 is listed as supported. Changing region (A) may work but is unnecessary; increasing unit count (C) or changing compartment (D) will not resolve the shape issue.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
