MCQmedium

A developer needs to generate embeddings for a set of search queries to be used in a semantic search system. Which input type should they specify when calling the Embedding API?

A.clustering
B.search_document
C.classification
D.search_query
AnswerD

This is optimized for short queries in search.

Why this answer

The Embedding API in OCI Generative AI requires specifying the input type as 'search_query' when generating embeddings for search queries in a semantic search system. This input type optimizes the embedding model to produce vectors that are specifically tuned for query-side representation, ensuring better alignment with document embeddings during similarity search.

Exam trap

The trap here is that candidates may confuse 'search_query' with 'search_document' or assume a generic input type like 'clustering' or 'classification' is valid, not realizing that the Embedding API explicitly distinguishes between query and document embeddings for optimal semantic search performance.

How to eliminate wrong answers

Option A is wrong because 'clustering' is not a valid input type for the Embedding API; it is a downstream task that uses embeddings but not a parameter for embedding generation. Option B is wrong because 'search_document' is used for embedding documents, not queries, and specifying it for queries would mismatch the intended use case, degrading search accuracy. Option C is wrong because 'classification' is not a supported input type for the Embedding API; classification tasks use embeddings but require a different API or model endpoint.

MCQhard

A developer is using the Chat API for a multi-turn conversation. They want the assistant to adopt a formal tone and always identify itself as 'OracleBot'. How should they configure the API request?

A.Include the persona instructions in the 'preamble_override' field and the conversation history in the 'messages' field of the Chat API
B.Set the 'temperature' parameter low and 'max_tokens' high
C.Use the Embedding API to embed the persona instructions and pass them with each request
D.Set the 'system_prompt' in the Generate API
AnswerA

Preamble override sets the assistant's behavior; messages carry the conversation history.

Why this answer

The Chat API supports a 'preamble_override' parameter to set system-level instructions, and 'messages' array for conversation history. The preamble is the correct place to set persona. Temperature and max tokens do not control persona.

The Generate API does not support system prompts.

A.Use the on-demand (shared) inference endpoint with the Summarisation API
B.Use OCI Generative AI Agents with a knowledge base
C.Provision a dedicated AI cluster for the batch job
D.Fine-tune a model on summarization and deploy it on a dedicated cluster
AnswerA

On-demand tokens are cost-effective for batch summarization.

Why this answer

On-demand pricing is pay-per-token, suitable for batch workloads without dedicated capacity; it's cost-effective for sporadic or large batch jobs.

6
MCQmedium

A.embed-english-v3.0
B.Cohere Command R
C.embed-multilingual-v3.0
D.Meta Llama 3
AnswerC

This model supports multiple languages and generates high-quality embeddings for English, Spanish, French, and many others.

Why this answer

The embed-multilingual-v3.0 model is designed for multilingual text. The English-only model would not handle other languages well.

Multi-Selectmedium

A company wants to build a RAG application using OCI Generative AI Agents. Which TWO components are required to set up the agent?

Select 2 answers
A.An embedding model
B.A knowledge base
C.A dedicated AI cluster
D.A data source (e.g., OCI Object Storage)
E.A fine-tuned model
AnswersB, D

Required to store indexed documents.

Why this answer

A knowledge base is the core repository that stores the indexed content used by OCI Generative AI Agents to retrieve relevant information for answering queries. Without a knowledge base, the agent has no source of domain-specific data to ground its responses, making it a mandatory component.

Exam trap

A common misconception is that you need to separately provision an embedding model or a dedicated AI cluster, when in fact OCI Generative AI Agents abstract these components away as part of the managed service, requiring only a data source and a knowledge base.

9

Why this answer

Cohere Command R+ and Meta Llama 3 support multiple languages.

10
MCQmedium

A developer is using the Embedding API to create embeddings for a clustering task. They want to ensure the embeddings are optimized for clustering similar documents. Which input type should they specify?

A.clustering
B.search_query
C.search_document
D.classification
AnswerA

Optimized for clustering.

Why this answer

The input type 'clustering' optimizes embeddings for clustering tasks.

11
MCQmedium

A developer uses the OCI Generative AI Chat API to build a multi-turn conversational agent. They notice the model starts to lose context after several exchanges. What is the MOST likely cause?

A.The temperature parameter is set too high, causing the model to forget
B.The model's context window is too small for the conversation length
C.The developer is not sending the conversation history with each request
D.The fine-tuning dataset did not include multi-turn examples
AnswerC

The Chat API requires the client to include previous messages; otherwise the model has no context of prior turns.

Why this answer

The Chat API does not automatically manage conversation history; the developer must provide previous messages. The model itself retains state only within the provided context.

12
MCQhard

An organization requires low-latency inference for a custom fine-tuned model that will be used in a real-time application. They also need guaranteed availability and isolation from other tenants. Which infrastructure option should they choose?

A.Provision a Dedicated AI Cluster with model units for the fine-tuned model
B.Create an endpoint on OCI API Gateway pointing to shared inference
C.Use the OCI Generative AI Playground to host the model
D.On-demand token-based inference on shared infrastructure
AnswerA

A Dedicated AI Cluster provides isolated compute resources, ensuring low latency and dedicated capacity for custom models.

Why this answer

Dedicated AI Clusters provide isolated, low-latency inference for custom models. Shared infrastructure is multi-tenant and may have higher latency. On-demand tokens and serving endpoints without a cluster do not offer dedicated resources.

13
MCQhard

An organization needs to fine-tune a Cohere Command R model for a custom domain. They have prepared a dataset in JSONL format. Which component of the fine-tuning job specifies the base model and the training dataset location?

A.The dedicated AI cluster settings
B.The T-Few configuration file
C.The fine-tuning job creation request body
D.The model deployment endpoint configuration
AnswerC

The request body specifies base model, dataset, and other settings for the fine-tuning job.

Why this answer

The fine-tuning job creation request includes parameters such as 'baseModelId' and 'trainingDataset' (pointing to the dataset in Object Storage). The model deployment endpoint and cluster are separate steps.

14
MCQhard

A developer is using the OCI Generative AI Chat API with Cohere Command R+ to build a multi-turn conversational agent. They want the agent to always respond in a formal tone, regardless of the user's phrasing. Which parameter should they set in the API request to achieve this consistently?

A.Set the 'stop_sequences' parameter to include periods
B.Set the 'temperature' parameter to 0.1
C.Use the 'system' parameter (or preamble_override) to provide a system message like 'You are a formal assistant'
D.Set the 'max_tokens' parameter to 200
AnswerC

The system message or preamble override instructs the model on its behavior and tone, which persists across the conversation.

Why this answer

A system message or preamble override sets the overall behavior and tone of the assistant for the entire conversation. Temperature controls randomness; max tokens limits length; stop sequences end generation — none are suitable for defining a persistent tone.

15
MCQhard

A machine learning engineer is fine-tuning a Cohere Command R model using T-Few. They have prepared a JSONL dataset with 500 prompt-completion pairs. After submitting the fine-tuning job, they notice the model's performance on validation data is poor. Which action is MOST likely to improve performance?

A.Adding more high-quality training examples to the dataset
B.Increasing the number of training epochs
C.Setting the temperature to 0 in the fine-tuning configuration
D.Switching to a larger base model like Llama 3 70B
AnswerA

More data can improve T-Few fine-tuning performance.

Why this answer

T-Few is parameter-efficient and may require more data. Increasing dataset size or using data augmentation is a likely improvement.

Select 3 answers
A.Increase the presence penalty
B.Increase the temperature
C.Increase the max tokens
D.Increase the frequency penalty
E.Decrease the temperature
AnswersA, D, E

Encourages the model to talk about new topics, reducing repetition.

Why this answer

Temperature controls randomness; frequency penalty reduces repetition of words/phrases; presence penalty encourages new topics.

17
MCQmedium

An application needs to generate embeddings for customer reviews to cluster them by sentiment. Which input type should be specified in the Embedding API call?

A.clustering
B.search_document
C.search_query
D.classification
AnswerA

The clustering input type tailors embeddings for clustering algorithms.

Why this answer

For clustering tasks, the 'clustering' input type optimizes the embeddings for that purpose. The other types are for different tasks.

18
MCQmedium

A machine learning engineer is preparing a dataset for fine-tuning a model in OCI Generative AI. The dataset consists of customer support conversations with questions and desired answers. What is the required format for the training data?

A.CSV file with columns 'input' and 'output'
B.Parquet file with 'text' and 'label' columns
C.Plain text file with examples separated by blank lines
D.JSONL file with 'prompt' and 'completion' fields per line
AnswerD

JSONL is the supported format with prompt/completion pairs.

Why this answer

OCI Generative AI expects a JSONL file where each line is a JSON object with 'prompt' and 'completion' fields. CSV, Parquet, and text files are not supported for fine-tuning.

19
MCQmedium

A company wants to build a RAG-based assistant that answers queries using documents stored in OCI Object Storage. Which OCI Generative AI service should they use?

A.OCI Generative AI Playground

An enterprise needs to deploy a custom fine-tuned model for real-time inference with strict latency requirements. They also need to manage costs by paying only for usage. Which three steps are required to achieve this? (Select THREE)

Select 3 answers
A.Use the on-demand token-based inference on shared infrastructure
B.Create an endpoint using InferenceClient to point to the dedicated cluster
C.Delete the fine-tuning job after deployment to save costs
D.Provision a Dedicated AI Cluster with sufficient model units
E.Host the fine-tuned model on the Dedicated AI Cluster
AnswersB, D, E

An endpoint enables API calls to the model hosted on the cluster.

Why this answer

To deploy a custom model for dedicated low-latency inference, you need a Dedicated AI Cluster, host the model on it, and create an endpoint to access it. Using shared infrastructure does not guarantee low latency. Deletion of cluster is not needed.

On-demand tokens are for pay-as-you-go, not dedicated clusters.

21
MCQmedium

A data scientist is fine-tuning a model using T-Few in OCI Generative AI. They have prepared a dataset with prompt/completion pairs. Which file format is required for the training data upload?

A.Plain text file with one prompt-completion pair per line separated by a tab
B.Parquet file with a 'text' column containing concatenated prompt and completion
C.CSV with columns 'input' and 'output'
D.JSONL with each line containing 'prompt' and 'completion' keys
AnswerD

The training dataset must be a JSONL file where each line is a JSON object with 'prompt' and 'completion' fields.

Why this answer

OCI Generative AI fine-tuning expects training data in JSONL format with specific fields.

22
MCQmedium

A financial services firm needs to ensure that only members of the 'DataScientists' group can use OCI Generative AI resources in the 'prod' compartment. Which IAM policy statement should be applied?

A.Allow group DataScientists to manage genai-family in tenancy
B.Allow group DataScientists to use ai-services in compartment prod
C.Allow group DataScientists to manage genai-family in compartment prod
D.Allow group DataScientists to read genai-family in compartment prod
AnswerC

This policy grants the group access to all GenAI resources in the prod compartment.

Why this answer

The 'manage' verb on the 'genai-family' resource type grants full access (including use) to OCI Generative AI resources, and scoping the policy to 'compartment prod' restricts the permission to only that compartment. The requirement is to allow the 'DataScientists' group to use (which implies manage-level access for creating and running inference jobs) Generative AI resources specifically in the 'prod' compartment, not the entire tenancy.

Exam trap

The trap here is that candidates often confuse the generic 'ai-services' resource type (which exists for other AI services like OCI AI Vision or OCI Language) with the specific 'genai-family' resource type required for OCI Generative AI, leading them to select Option B.

How to eliminate wrong answers

Option A is wrong because it grants access to 'genai-family in tenancy', which would allow the group to manage Generative AI resources across all compartments, violating the requirement to restrict access to only the 'prod' compartment. Option B is wrong because 'ai-services' is not a valid resource type for OCI Generative AI; the correct resource type is 'genai-family', and using 'ai-services' would match no resources, effectively granting no access. Option D is wrong because the 'read' verb only allows viewing metadata and listing resources, but does not permit using (creating, updating, or invoking) Generative AI models, which is required for the DataScientists to actually work with the AI services.

23
MCQeasy

A user wants to quickly test different prompts and parameters (temperature, max tokens) with various OCI Generative AI models without writing any code. Which tool should they use?

A.The InferenceClient SDK in Python
B.OCI CLI with generative-ai commands
C.The OCI Generative AI Playground
D.OCI Cloud Shell
AnswerC

The Playground is the no-code interface for experimenting with models.

Why this answer

The OCI Generative AI Playground provides an interactive web UI to test models and adjust parameters.

24
Multi-Selectmedium

A team is planning to use OCI Generative AI to summarize large documents. They need to choose between on-demand (pay-as-you-go) and dedicated cluster pricing. Which THREE factors should they consider when deciding? (Choose three.)

Select 3 answers
A.Throughput requirements and consistency
B.Latency sensitivity of the application
C.Model accuracy on summarization tasks
D.Data residency requirements
E.Cost predictability and budget constraints
AnswersA, B, E

Dedicated clusters guarantee throughput; on-demand is shared and may throttle.

Why this answer

Latency sensitivity, throughput consistency, and cost predictability are key factors. On-demand is variable cost with potential contention; dedicated offers fixed cost with reserved capacity. Model accuracy does not differ based on pricing model, and data residency is a compliance factor but not directly tied to pricing model choice.

25
MCQmedium

A data scientist is using the OCI Generative AI Playground to test a summarization model. They want to generate shorter summaries and avoid repetitive phrasing. Which parameter adjustments should they make?

A.Decrease temperature and increase frequency penalty
B.Increase temperature and increase presence penalty
C.Set stop sequences and disable frequency penalty
D.Increase temperature and decrease frequency penalty
AnswerA

Lower temperature makes output more deterministic (focused summaries), and higher frequency penalty discourages repetition, achieving the goal.

Why this answer

Lowering temperature reduces randomness, increasing frequency penalty penalizes repeated tokens, and setting appropriate max tokens controls output length. Stop sequences define when generation stops, and presence penalty penalizes token presence overall.

26
Multi-Selectmedium

A company wants to reduce costs for a high-volume, latency-tolerant text generation workload using OCI Generative AI. Which TWO strategies should they consider?

Select 2 answers
A.Use on-demand (pay-per-token) pricing instead of a dedicated AI cluster
B.Provision a dedicated AI cluster for consistent throughput
C.Increase the temperature parameter to reduce token usage
D.Use the largest available model to ensure best quality
E.Use a smaller, faster model like Cohere Command R instead of Command R+
AnswersA, E

On-demand pricing is cost-effective for variable or high-volume workloads without dedicated infrastructure commitment.

Why this answer

On-demand pricing (pay-per-token) and using a smaller/faster model (like Command R instead of R+) are cost-saving measures. Dedicated clusters increase cost; the largest model is more expensive; increasing temperature doesn't affect pricing.

27
MCQmedium

A security administrator needs to grant a group of data scientists the ability to use OCI Generative AI service resources in the compartment 'genai-dev'. They want to allow the group to create endpoints and run inference, but not to manage IAM policies. Which policy statement is correct?

A.Allow group DataScientists to use generative-ai-family in compartment genai-dev
B.Allow group DataScientists to manage generative-ai-family in compartment genai-dev
C.Allow group DataScientists to inspect generative-ai-family in compartment genai-dev
D.Allow group DataScientists to read generative-ai-family in compartment genai-dev
AnswerA

'use' allows creating endpoints and running inference without granting policy management.

Why this answer

The 'use' verb in OCI IAM policies grants the ability to perform operational actions on resources without allowing management or administrative changes. For the OCI Generative AI service, 'use generative-ai-family' permits data scientists to create endpoints and run inference (the core actions needed), while explicitly preventing them from managing IAM policies or altering resource configurations. This aligns with the principle of least privilege required by the security administrator.

Exam trap

The trap here is that candidates often confuse 'use' with 'manage' or 'read', assuming that creating endpoints requires 'manage' permissions, but OCI's 'use' verb is specifically designed for operational tasks like running inference and creating resources within a compartment without granting full administrative rights.

How to eliminate wrong answers

Option B is wrong because 'manage' grants full administrative control, including creating, updating, and deleting resources, as well as managing IAM policies, which exceeds the required permissions. Option C is wrong because 'inspect' only allows listing resources and reading metadata, not creating endpoints or running inference. Option D is wrong because 'read' permits viewing resource details but does not allow any write or operational actions like creating endpoints or invoking inference.

28
MCQeasy

Which OCI Generative AI model is best suited for generating embeddings from text that can be used for semantic search across multiple languages?

A.Cohere Command R+
B.Cohere embed-multilingual-v3.0
C.Meta Llama 3 70B
D.Cohere Rerank
AnswerB

This model is specifically built for multilingual embeddings, supporting semantic search across many languages.

Why this answer

Embed-multilingual-v3.0 is designed for multilingual embedding tasks. The other models are primarily for text generation or English-only embeddings.

29
MCQmedium

A team wants to use OCI Generative AI Agents to build a RAG system that answers questions from documents stored in OCI Object Storage. What must they create first?

A.A knowledge base that indexes the documents from Object Storage
B.A fine-tuned model on the documents
C.A dedicated AI cluster for the agent
D.An OCI Functions endpoint to process documents
AnswerA

The knowledge base links the data source to the agent and enables retrieval.

Why this answer

The agent requires a knowledge base that is connected to the data source. Directly creating a session without a knowledge base and agent will fail.

30
MCQmedium

A developer is using the OCI Generative AI Agents service to build a RAG application. They have uploaded policy PDFs to an OCI Object Storage bucket. What is the next step to make the documents searchable?

A.Create a dedicated AI cluster to host the documents
B.Use the Embeddings API to embed each PDF manually
C.Fine-tune a model on the PDFs
D.Create a knowledge base from the Object Storage bucket
AnswerD

The knowledge base indexes the documents from Object Storage and enables retrieval.

Why this answer

In OCI Generative AI Agents, you create a knowledge base from data sources like Object Storage. The agent then uses this knowledge base to retrieve relevant information for answering questions. Creating a dedicated cluster or fine-tuning is not required for RAG with agents.

31
Multi-Selectmedium

A developer is creating a fine-tuning job for a Cohere Command R model using OCI Generative AI. Which TWO of the following are required when submitting the fine-tuning job?

Select 2 answers
A.Base model name (e.g., Cohere Command R)
B.A Dedicated AI Cluster ID
C.A pre-trained embedding model
D.Training dataset in JSONL format with prompt/completion pairs
E.Hyperparameters file in YAML format
AnswersA, D

You must specify which model to fine-tune.

Why this answer

The training dataset and the base model are mandatory inputs for a fine-tuning job. The compartment is part of the resource configuration, and the hyperparameters file is optional but not required.

32
MCQeasy

You are using the OCI Generative AI Playground with a Cohere Command R model. You want the model to generate more varied and creative responses. Which parameter should you increase?

A.Temperature
B.Stop sequences
C.Max tokens
D.Frequency penalty
AnswerA

Increasing temperature (e.g., to 0.8) increases randomness and variety in the generated text, making responses more creative.

Why this answer

Temperature controls the randomness of the output. Higher temperature (e.g., 0.8) makes the model more creative and varied. Max tokens, frequency penalty, and stop sequences do not primarily affect creativity.

33
MCQeasy

Which OCI Generative AI model is designed to rerank and improve the relevance of documents retrieved by a search system?

A.Cohere Rerank
B.Cohere Embed
C.Cohere Command R
D.Meta Llama 3
AnswerA

Rerank is purpose-built for reranking search results.

Why this answer

Cohere Rerank is specifically designed for reranking documents to improve relevance ranking.

34
MCQmedium

A data scientist needs to fine-tune a model using OCI Generative AI. They have prepared a dataset in JSONL format with prompt/completion pairs. The fine-tuning job is configured with the T-Few technique. What is a key characteristic of T-Few fine-tuning?

A.It requires unlabeled data for unsupervised pre-training before fine-tuning
B.It updates all model parameters, requiring significant compute resources
C.It modifies a small subset of parameters using lightweight adapter layers
D.It only trains a new classification head on top of a frozen base model
AnswerC

T-Few uses adapter-based fine-tuning that updates a small number of parameters while keeping most of the model frozen.

Why this answer

T-Few is a parameter-efficient fine-tuning method that updates only a small fraction of model parameters, making it faster and more resource-efficient than full fine-tuning. It does not train all parameters, add new layers, or require unlabeled data.

35
MCQmedium

A company uses OCI Generative AI Agents to build a RAG application that answers questions from documents stored in OCI Object Storage. The knowledge base is updated daily. Which step is necessary to ensure the agent incorporates the latest documents?

A.Re-sync the knowledge base after updating the documents in Object Storage
B.Use the Embedding API to manually index each new document
C.Set the session API to refresh automatically
D.Recreate the agent each time documents change
AnswerA

Re-syncing the knowledge base indexes the new or updated documents, making them available for retrieval by the agent.

Why this answer

The knowledge base indexes the data sources. To reflect changes in the source documents, you must re-sync or re-index the knowledge base. The agent endpoint or session API does not automatically refresh content.

36
MCQeasy

Which OCI Generative AI service component is designed to convert text into vector representations for use in semantic search?

A.Chat API
B.Summarisation API
C.Generate API
D.Embedding API
AnswerD

Embedding API produces vector embeddings from text inputs.

Why this answer

The Embedding API generates vector embeddings from text, which can be used for semantic search, clustering, etc.

37
MCQmedium

A developer is using the OCI GenAI Chat API to build a multi-turn customer support chatbot. They want the assistant to always introduce itself as 'SupportBot' and never mention being an AI. How should they configure the API call?

A.Use the Generate API instead and include the instruction in the prompt
B.Set the preamble override to a JSON object with the assistant's identity
C.Set the system message (preamble) to 'You are SupportBot. You must never mention that you are an AI.'
D.Set the first user message to 'Introduce yourself as SupportBot and never say you are an AI.'
AnswerC

The system message (preamble) defines the assistant's persona and instructions.

Why this answer

The OCI GenAI Chat API supports a 'system message' or 'preamble' parameter that sets the assistant's behavior and identity for the entire conversation. By setting the preamble to 'You are SupportBot. You must never mention that you are an AI.', the developer enforces the desired persona and restriction across all turns, ensuring the assistant introduces itself as SupportBot and avoids any reference to being an AI.

Exam trap

A common trap in the OCI GenAI exam is confusing the system message (preamble) parameter with a regular user message. Candidates may think placing instructions in the first user message is sufficient, but only the dedicated preamble parameter enforces behavior across all turns. The Chat API requires explicit use of the preamble to set persistent assistant identity and restrictions.

How to eliminate wrong answers

Option A is wrong because the Generate API is a single-turn text generation endpoint that does not support multi-turn conversation context or persistent system instructions; using it would require manually managing conversation history and re-injecting the instruction in every prompt, which is inefficient and error-prone. Option B is wrong because the OCI GenAI Chat API does not accept a 'preamble override' as a JSON object; the correct parameter is a plain text string for the system message (preamble), and a JSON object would be rejected or misinterpreted. Option D is wrong because setting the first user message to include the instruction does not persist across turns; the assistant might follow it initially but could deviate in subsequent responses, and the instruction is not enforced as a system-level constraint.

38
MCQmedium

A company wants to use OCI Generative AI Agents to build a question-answering system over documents stored in OCI Object Storage. Which component acts as the knowledge source for the agent?

A.A Dedicated AI Cluster
B.The OCI Generative AI Playground
C.An endpoint created via the InferenceClient
D.A knowledge base created from the Object Storage bucket
AnswerD

The knowledge base indexes documents from the data source (Object Storage) for retrieval.

Why this answer

In OCI Generative AI Agents, a knowledge base is the indexed representation of data sources (like Object Storage buckets). The agent uses the knowledge base to retrieve relevant information.

39
MCQeasy

You need to convert a set of customer support tickets into vector embeddings for a similarity search application. Which OCI Generative AI model should you use?

A.Cohere Rerank
B.Cohere Embed (e.g., embed-english-v3.0)
C.Meta Llama 3
D.Cohere Command R
AnswerB

Cohere Embed models are specifically designed to generate dense vector embeddings from text, ideal for similarity search and retrieval tasks.

Why this answer

The Cohere Embed models are designed for text-to-vector embedding. The other options are for text generation or reranking.

40
MCQmedium

A regulatory compliance team needs to restrict access to the OCI Generative AI service so that only users in the 'AI_Engineers' group can create fine-tuning jobs and endpoints. Which IAM policy statement should be used?

A.Allow group AI_Engineers to inspect generative-ai-family in compartment ABC
B.Allow group AI_Engineers to manage generative-ai-family in tenancy
C.Allow group AI_Engineers to read generative-ai-family in compartment ABC
D.Allow group AI_Engineers to use generative-ai-family in compartment ABC
AnswerD

'use' permission includes the ability to create, update, and delete generative AI resources.

Why this answer

To allow a group to manage generative AI resources, you allow them to use the 'generative-ai-family' resource type. Specific verbs like 'inspect' limit visibility but not management. 'Read' only allows viewing, not creating.

41
MCQmedium

A data scientist is creating a fine-tuning job in OCI Generative AI. They have prepared a JSONL dataset with prompt/completion pairs. What is the correct format for each line in the JSONL file?

A.{"input": "What is OCI?", "output": "Oracle Cloud Infrastructure is a cloud computing platform."}
B.{"prompt": "What is OCI?", "completion": "Oracle Cloud Infrastructure is a cloud computing platform."}
C.{"text": "What is OCI?", "label": "Oracle Cloud Infrastructure is a cloud computing platform."}
D.{"question": "What is OCI?", "answer": "Oracle Cloud Infrastructure is a cloud computing platform."}
AnswerB

This is the correct JSON format with 'prompt' and 'completion' fields.

Why this answer

The OCI Generative AI fine-tuning service expects JSONL files where each line contains exactly the keys "prompt" and "completion". This format matches the service's internal training pipeline, which maps the prompt to the input and the completion to the expected output during supervised fine-tuning.

Exam trap

The trap here is that candidates often confuse the key names with those used in other AI services (like OpenAI's fine-tuning which uses "prompt" and "completion" as well, but OCI's documentation explicitly requires these exact keys, and the exam tests attention to the specific OCI schema).

Option A is wrong because it uses "input" and "output" keys, which are not recognized by the OCI Generative AI fine-tuning API; the service requires the exact key names "prompt" and "completion". Option C is wrong because it uses "text" and "label" keys, which are commonly used in classification tasks but not for prompt/completion fine-tuning in OCI Generative AI. Option D is wrong because it uses "question" and "answer" keys, which are not the expected schema; the service strictly enforces the "prompt" and "completion" key names for JSONL lines.

A team fine-tuned a Cohere Command R model using the T-Few technique on a dataset of JSONL prompt/completion pairs. After deployment, they observe that the model's responses are too repetitive. Which parameter adjustment in the OCI Generative AI Playground would BEST address this issue?

A.Increase frequency penalty
B.Increase max tokens
C.Decrease temperature
D.Add a stop sequence
AnswerA

Increasing the frequency penalty reduces the likelihood of the model repeating the same tokens or phrases by subtracting a penalty value from the logits of tokens that have already appeared in the generated text. This directly addresses the repetitive responses observed after fine-tuning with the T-Few technique, which can overfit to common patterns in the JSONL prompt/completion pairs.

Why this answer

Increasing the frequency penalty discourages the model from repeating tokens that have already appeared, reducing repetitive outputs. Temperature and max tokens address randomness and length, not repetition specifically. Stop sequences are for terminating generation early.

A company is using OCI Generative AI Agents to build a customer support assistant. They have uploaded product manuals to OCI Object Storage. Which two components are required to create the agent? (Select TWO)

Select 2 answers
A.Create a Generative AI Agent using the knowledge base
B.Create an endpoint via InferenceClient
C.Create a knowledge base from the Object Storage bucket
D.Upload data directly to the agent (not via knowledge base)
E.Provision a Dedicated AI Cluster
AnswersA, C

The agent uses the knowledge base to answer questions.

Why this answer

A Generative AI Agent requires a knowledge base to provide domain-specific context for answering queries. The knowledge base is the source of truth that the agent uses to ground its responses, and it must be explicitly created and associated with the agent. Without a knowledge base, the agent would lack the product manual data needed for customer support.

Exam trap

A common misconception in OCI is that you can directly upload data to a Generative AI Agent or that you must manually create an endpoint, but in reality the agent relies on a knowledge base for data ingestion and uses a managed endpoint automatically.

During fine-tuning a model using T-Few in OCI Generative AI, the job fails with a 'dataset format error'. The training dataset is a JSONL file. Which of the following is the MOST likely cause?

A.The file contains more than 1000 lines
B.Some lines have an extra 'metadata' key
C.The completion field contains more than 1024 tokens
D.The file uses Unix line endings
AnswerB

The dataset format expects only 'prompt' and 'completion'. Extra keys like 'metadata' are not allowed and cause validation errors.

Why this answer

Each JSONL line must contain exactly 'prompt' and 'completion' keys. Extra keys or missing keys cause format errors.

An organization requires low-latency inference for a custom fine-tuned model deployed on OCI Generative AI. The model must be isolated from other tenants. Which infrastructure choice meets these requirements?

A.Use the shared infrastructure endpoint for the fine-tuned model
B.Deploy the model on OCI Data Science model deployment
C.Provision a dedicated AI cluster with the required model units
D.Use an on-premises GPU server and call OCI GenAI via API gateway
AnswerC

A dedicated AI cluster provides isolated compute resources, ensuring low latency and no interference from other workloads.

Why this answer

A dedicated AI cluster provides isolated, low-latency inference for custom models. Shared infrastructure does not guarantee isolation and may have higher latency due to contention.

MCQmedium

A company wants to build a customer service chatbot that answers questions about their internal policy documents. The documents are updated monthly, and the team cannot afford to retrain a model each time. Which approach is MOST appropriate?

A.Use Retrieval-Augmented Generation (RAG) with the policy documents indexed in a vector store
B.Train a custom model from scratch on the policy documents each month
C.Use a larger foundation model with a longer context window and paste all documents into each prompt
D.Fine-tune a base LLM on the policy documents monthly
AnswerA

RAG retrieves relevant document chunks at query time, ensuring the chatbot always answers from the latest uploaded documents without any model retraining.

Why this answer

RAG (Retrieval-Augmented Generation) allows the LLM to retrieve relevant document sections at inference time, so knowledge stays current without retraining. The other options either require expensive retraining for each update or lack document grounding.

A developer is using the OCI Generative AI Chat API with a system prompt to guide the assistant's behavior. They notice that after a few turns, the assistant starts ignoring the system instructions. What is the MOST likely cause?

A.The temperature is set too high, causing the model to ignore instructions
B.The system prompt (preamble) is only sent once and may be truncated as the conversation grows
C.The model is not fine-tuned to follow system prompts
D.The conversation history is not being sent with subsequent requests, so the model loses context
AnswerB

In the Chat API, the preamble is sent only at the start; if the conversation history exceeds the context window, the preamble may be dropped, causing the model to lose instructions.

Why this answer

The preamble is sent only on the first turn; it may be truncated or lost as conversation history grows. The developer should inject the preamble in each request or manage history carefully.

A company wants to implement a retrieval-augmented generation (RAG) chatbot using OCI Generative AI Agents. Which TWO services or components are required for this solution?

Select 2 answers
A.Cohere Embed model
B.Fine-tuned model
C.Knowledge Base
D.OCI Object Storage
E.Dedicated AI Cluster
AnswersC, D

The knowledge base indexes documents and enables retrieval.

Why this answer

A Knowledge Base is the core repository that stores the documents or data sources the RAG chatbot retrieves from. OCI Generative AI Agents use a knowledge base to perform retrieval-augmented generation, where the agent first retrieves relevant chunks from the knowledge base and then passes them to the generative model to produce a grounded, context-aware response.

Exam trap

The trap here is that candidates often assume a dedicated AI cluster or a specific embedding model is mandatory for RAG, when in fact OCI Generative AI Agents abstract away these details and only require a knowledge base and a data source like Object Storage.

During a fine-tuning job for a text generation model, the loss curve shows that the training loss decreases steadily, but the evaluation loss increases after a few epochs. Which action is most likely to improve the model's generalization?

A.Implement early stopping based on evaluation loss
B.Increase the number of training epochs
C.Reduce the size of the training dataset
D.Increase the temperature parameter during generation
AnswerA

Early stopping halts training when evaluation loss starts increasing, preventing overfitting.

Why this answer

Increasing evaluation loss while training loss decreases indicates overfitting. Early stopping prevents further training once evaluation metrics plateau or degrade, improving generalization. Reducing dataset size or increasing epochs would worsen overfitting; increasing temperature does not affect training.
