NEW QUESTION # 14
In OpenAI Agents SDK, how does the model select which tool to call?
Answer: C
Explanation:
Tool selection in the OpenAI Agents SDK is model-driven. Each function tool exposes structured metadata that gives the model enough information to determine whether the tool is appropriate and how it should be invoked. The SDK represents a function tool using a name , description , and JSON parameter schema .
OpenAI's SDK reference explicitly defines these properties as information shown to the LLM, while function- tool helpers automatically generate the parameter schema from the Python function signature and derive descriptions from documentation when available.
During an agent run, the model evaluates the user's request together with the available tool definitions. It can then select an appropriate tool and generate arguments conforming to that tool's schema. This mechanism is fundamentally semantic and contextual: meaningful names and descriptions tell the model what a tool does, while schemas describe the arguments required to execute it.
There is no rule requiring the first registered tool to be selected, every tool to be invoked, or random selection.
Such behavior would undermine agentic reasoning and dynamic orchestration. Consequently, B is the technically correct answer and is explicitly identified as correct in the uploaded question set.

NEW QUESTION # 15
Why is chunking necessary before generating embeddings for large documents?
Answer: D
Explanation:
Embedding models accept inputs only up to their supported input-size or token limits. Large documents can exceed those limits and therefore must be divided into smaller segments before embedding generation. The course source explicitly identifies overcoming token limits as the reason for chunking.
Oracle AI Vector Search includes native chunking functionality that can split text according to characters, words, or model vocabulary tokens. Oracle's Vector Search guidance specifically states that input length must remain within the token limits of the embedding model and provides configurable maximum chunk sizes.
Chunking also provides an important retrieval benefit. Instead of representing an entire long document with one coarse embedding, the system creates embeddings for semantically meaningful sections. A similarity query can then retrieve only the chunks most relevant to the user's question, reducing irrelevant context and improving retrieval-augmented generation precision.
Chunking does not intentionally remove semantic meaning; well-designed chunking attempts to preserve it. It does not automatically provide encryption, and SQL storage format is not its underlying purpose.
Therefore, A is correct.

NEW QUESTION # 16
Which statement describes the OCI Responses API?
Answer: A
Explanation:
The OCI Responses API is explicitly designed as an OpenAI-compatible API for interacting with supported models and constructing agentic workflows. Oracle documents it as both OpenAI-compatible and Open Responses-compliant, allowing applications to use familiar Responses API request structures and the OpenAI SDK while routing execution to OCI Generative AI. The uploaded examination source likewise marks B as correct.
Compatibility is important because developers can use established client patterns rather than adopting a proprietary OCI-only programming interface. Oracle specifically recommends the OpenAI SDK for calling the OCI Responses API. The OCI endpoint differs in its base URL, authentication model, available OCI- hosted models, and platform governance, but the request structure follows the compatible Responses API model.
The interface is also not restricted to a single model provider. OCI supports multiple supported hosted models.
Nor is the API read-only: agent workflows can use Function Calling and MCP Calling, allowing applications to execute external actions through controlled tool implementations. It also supports File Search and Code Interpreter.
Therefore, the defining statement among the choices is B.

NEW QUESTION # 17
In the OpenAI Agents SDK, what is the role of the Runner?
Answer: C
Explanation:
The Runner is responsible for executing the OpenAI Agents SDK agent loop. The uploaded course source identifies this directly as the Runner's role.
When Runner.run() , Runner.run_sync() , or Runner.run_streamed() is invoked, the Runner starts with an agent and user input, calls the configured model, evaluates the model output, and decides what happens next.
If the output is final, execution terminates. If the model requests a tool call, the Runner executes the tool, appends the result, and calls the model again. If the model produces a handoff, the Runner updates the active agent and continues the loop. OpenAI's official documentation describes precisely this lifecycle.
The Runner is therefore an orchestration/runtime component rather than an agent-hosting deployment service.
Authentication configuration exists separately, and function-tool JSON schemas are generated by the tool- definition mechanisms rather than being the Runner's primary responsibility.
This distinction is central to the SDK architecture: the Agent defines behavior and capabilities , while the Runner executes the iterative workflow .
Therefore, C is correct.

NEW QUESTION # 18
Which statement describes an MCP Host?
Answer: A
Explanation:
The MCP Host is the top-level AI application in the Model Context Protocol architecture. Its responsibility is to coordinate the broader application experience and manage the MCP clients used to connect with one or more MCP servers. The official MCP architecture specifies that an MCP host creates a separate MCP client for each server connection and describes the host as the AI application that coordinates and manages one or multiple MCP clients.
The distinction between host, client, and server is essential. An MCP client maintains the protocol connection to a corresponding MCP server. An MCP server exposes capabilities such as tools, resources, and prompts.
The host integrates these connections with the AI application's model and user interaction flow. Therefore, it is incorrect to define the host as the protocol specification itself, an external REST service, or the component that necessarily implements each individual tool.
Option D most accurately represents this orchestration role: the host coordinates the LLM-facing application and MCP client connections to the servers providing capabilities. The source question identifies D accordingly.
