Practice scenarios

Question 1mediummultiple choice

Full question →

Refer to the exhibit. An administrator receives the error shown when attempting to deploy a custom model. What is the most likely cause?

Network Topology

A
The user or service does not have permission to read the model artifact from Object Storage
The 403 error indicates lack of IAM permissions to access the bucket.
B
The compartment ID is incorrect
Why wrong: An incorrect compartment ID would result in a different error, not 403 Forbidden.
C
The model artifact file is corrupted
Why wrong: Corrupted files would cause a different error (e.g., 400) during artifact processing.
D
The dedicated AI cluster ID is invalid
Why wrong: An invalid cluster ID would likely give a 404 or validation error.

Question 2hardmultiple choice

Full question →

Refer to the exhibit. A developer encounters this error. Which action should they take to resolve the issue?

Network Topology

A
Wait and retry after some time.
Rate limit errors require waiting for the quota to reset, typically after a short period. Automatic retries with backoff are recommended.
B
Change the model to cohere.command-light.
Why wrong: Model choice does not bypass rate limits; each model and endpoint has its own rate limits.
C
Increase the max-tokens value.
Why wrong: Increasing max-tokens would likely increase resource usage and could exacerbate rate limiting.
D
Decrease the temperature to 0.0.
Why wrong: Temperature does not affect rate limits; it controls token selection randomness.

Question 3mediummultiple choice

Full question →

Refer to the exhibit. A user receives this error when calling the OCI Gen AI inference endpoint. What is the most likely cause?

Exhibit

{
  "status": 400,
  "code": "InvalidParameter",
  "message": "The model 'cohere.command-light' is not supported in region 'us-phoenix-1'."
}

A
The region name is misspelled
Why wrong: Misspelled region would give a different error about region not found.
B
The model is not deployed in the region
The error indicates the model is not supported in that region.
C
The API key is expired
Why wrong: Expired API key returns 401 Unauthorized.
D
The model name is incorrect
Why wrong: Incorrect model name returns 'model not found' error.

Question 4hardmultiple choice

Full question →

Refer to the exhibit. A developer runs the OCI CLI command and receives the output. However, the text "Hello, how are you?" is actually a mix of English and French words. Why does the model assign only 0.03 to French?

Network Topology

A
The text is overwhelmingly English, so the model assigns a low probability to French.
The phrase is mostly English, so the model is confident it is English.
B
The model is limited to identifying a single language per query.
Why wrong: The output shows multiple languages, so it can output multiple.
C
The model cannot detect multiple languages in a single text.
Why wrong: The model outputs multiple languages with scores, so it can detect multiple.
D
The model's scores are normalized to sum to 1, so a high English score forces low others.
Why wrong: Normalization is true, but the model could still assign higher if French were more prominent.

Question 5easymultiple choice

Full question →

Refer to the exhibit. Users in the group cannot create a new custom model deployment on a Dedicated AI Cluster. What is the most likely missing permission?

Exhibit

Allow group GenAI-Admin to manage dedicated-ai-clusters in compartment FinComp
Allow group GenAI-Admin to manage custom-models in compartment FinComp
Allow group GenAI-Admin to read object-storage in compartment FinComp

A
Manage ai-document-understanding
Why wrong: Document understanding is another AI service, unrelated.
B
Manage ai-agents
Why wrong: AI agents are a different service for conversational AI, not required for cluster deployment.
C
Use of virtual-network-family for cluster networking
Dedicated AI Clusters require VCN networking permissions to provision networking resources.
D
Manage instance-configurations
Why wrong: Instance configurations are for compute instances, not Dedicated AI Clusters.

Question 6mediummultiple choice

Full question →

Refer to the exhibit. A developer ran the OCI CLI command shown and received the JSON output. What does the output indicate about the model's confidence and why?

Exhibit

Refer to the exhibit.

```
oci ai language text-classification --text "The product is amazing!"
{
  "data": {
    "labels": [
      {"name": "positive", "score": 0.98},
      {"name": "negative", "score": 0.01},
      {"name": "neutral", "score": 0.01}
    ]
  }
}
```

A
The model is uncertain because all scores are roughly equal.
Why wrong: Scores are not equal; positive score is 0.98.
B
The model is neutral because the neutral score is lowest.
Why wrong: Neutral score is low, but positive is high.
C
The model is unsure because the scores are probabilities that sum to 1.
Why wrong: Probabilities summing to 1 is normal; high probability indicates confidence.
D
The model is highly confident the text is positive, as indicated by the 0.98 score.
0.98 is very close to 1, indicating high confidence.

Question 7mediummultiple choice

Full question →

Refer to the exhibit. What is the solution?

Network Topology

A
Use a different base model that supports fine-tuning.
The error indicates the base model does not support fine-tuning; switch to a supported model.
B
Change the learning rate.
Why wrong: Learning rate is fine-tuning parameter but does not enable fine-tuning on an unsupported model.
C
Increase the training epochs.
Why wrong: Epochs do not affect model support for fine-tuning.
D
Use a different compartment.
Why wrong: Compartment does not affect model capabilities.

Question 8hardmultiple choice

Full question →

Refer to the exhibit. A developer has set this policy to allow an OCI Data Science session to generate embeddings. However, the API call returns a 403 Forbidden. Which of the following is likely missing?

Exhibit

{
  "policy": "Allow dynamic-group RAGGroup to use generative-ai-embeddings in compartment Production"
}

A
The policy needs a 'where request.region != ...' condition
Why wrong: Region conditions are not required for this permission.
B
The policy should include 'in tenancy' instead of compartment
Why wrong: Using 'in compartment' is acceptable and more restrictive.
C
The service requires 'manage' permission instead of 'use'
Why wrong: 'Use' is sufficient for generating embeddings.
D
The dynamic group does not include the Data Science session
The session must be matched by a rule in the dynamic group for the policy to apply.

Question 9mediummultiple choice

Full question →

Refer to the exhibit. A developer runs the command and receives the error. What is the issue?

Network Topology

A
The max-tokens value exceeds the allowed range.
The error explicitly states the valid range.
B
The message is too short.
Why wrong: Message length is not the issue.
C
The chat-id is invalid.
Why wrong: The error does not mention chat-id.
D
The endpoint is incorrect.
Why wrong: The endpoint is valid; the error is about max-tokens.

Question 10hardmultiple choice

Full question →

Refer to the exhibit. A user runs the command shown and receives the error: 'ServiceError: NotAuthorizedOrNotFound'. What is the MOST likely cause?

Network Topology

A
The CLI is not configured with OCI credentials
Why wrong: Missing credentials would give an authentication error, not NotAuthorizedOrNotFound.
B
The user does not have the 'inspect' permission on the model
NotAuthorizedOrNotFound is common when permissions are insufficient.
C
The model ID is incorrectly formatted
Why wrong: An invalid format would likely cause a validation error, not a 404/403.
D
The model is in a different region than iad
Why wrong: Region mismatch would give a different error.

Question 11mediummultiple choice

Full question →

Refer to the exhibit. A team created this dedicated AI cluster. However, when they try to create a model deployment, the deployment fails with an error indicating insufficient public IPs. What change to the cluster configuration should they make?

Exhibit

{
  "compartmentId": "ocid1.compartment.oc1..xxxxx",
  "displayName": "llama-cluster",
  "aiClusterShape": "VM.GPU.A10.1",
  "nodeCount": 4,
  "networkConfiguration": {
    "subnetId": "ocid1.subnet.oc1.iad.xxxxx",
    "assignPublicIp": false
  }
}

A
Change assignPublicIp to true.
Correct: Enabling public IPs allows nodes to have public endpoints.
B
Increase the nodeCount to 8.
Why wrong: Incorrect: Adding nodes increases IP demand, making the problem worse.
C
Attach a different subnet that has more available public IPs.
Why wrong: Incorrect: This might help but does not address the assignPublicIp=false setting; the cluster still wouldn't use public IPs.
D
Change the AI cluster shape to VM.GPU.A10.2.
Why wrong: Incorrect: Shape change does not affect IP allocation.

Question 12mediummultiple choice

Full question →

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?

Network Topology

A
The model ID is not available in us-ashburn-1
Why wrong: The CLI would likely validate the model ID and reject if unavailable.
B
The purpose parameter is misspelled
Why wrong: The purpose parameter is a string label and does not affect provisioning.
C
The endpoint is in provisioning state and not yet ready
Endpoints take time to provision; using them immediately fails.
D
The compartment ID is incorrect
Why wrong: An incorrect compartment ID would cause a different error during creation.

Question 13hardmultiple choice

Full question →

Refer to the exhibit. A user in GenAI-Users group tries to run a text generation inference but gets permission denied. What is the most likely issue?

Exhibit

IAM Policy:
Allow group GenAI-Users to use generative-ai-family in compartment ABC where request.operation = 'TextGeneration'

A
The policy resource type is wrong.
Why wrong: generative-ai-family is a valid resource type.
B
The operation condition is too restrictive.
The condition likely does not match the actual operation, causing denial.
C
The group name mismatch.
Why wrong: Group name appears correct; no evidence of mismatch.
D
The user is not in the compartment.
Why wrong: The policy allows the group, and compartment is specified; user could be in another compartment but group access is compartment-wide.
