1Z0-1127-25 Practice Question: Building LLM Applications with RAG and Vector Search
Network Topology
Refer to the exhibit. A developer runs the command and immediately tries to use the endpoint. The application fails with an error indicating the endpoint is not active. What is the most likely reason?
⚠ Common exam trap
Oracle often tests the asynchronous nature of OCI resource creation, where candidates mistakenly assume the endpoint is immediately usable after the create command returns a success response.
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
✓
The endpoint is in provisioning state and not yet ready
When a developer creates a new model deployment endpoint in OCI, the endpoint enters a 'provisioning' state and can take several minutes to become active. Attempting to use the endpoint immediately after creation will result in an error indicating the endpoint is not ready, as the underlying infrastructure and model loading must complete before inference requests are accepted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The model ID is not available in us-ashburn-1
Why it's wrong here
The CLI would likely validate the model ID and reject if unavailable.
- ✗
The purpose parameter is misspelled
Why it's wrong here
The purpose parameter is a string label and does not affect provisioning.
- ✓
The endpoint is in provisioning state and not yet ready
Why this is correct
Endpoints take time to provision; using them immediately fails.
- ✗
The compartment ID is incorrect
Why it's wrong here
An incorrect compartment ID would cause a different error during creation.
