問題 #42
In JSON-RPC 2.0, what is the difference between a request and a notification?
答案：B
解題說明：
The defining distinction is the presence of a request identifier and the expectation of a corresponding response. In JSON-RPC 2.0, a normal request contains an id value so that the sender can correlate the response with the request. A notification deliberately omits the ID because no response is expected. The supplied course material identifies exactly this distinction.
MCP uses JSON-RPC 2.0 as its underlying messaging protocol. Its architecture documentation explicitly states that clients and servers exchange requests and responses, while notifications are used where no response is required. MCP's notification examples contain no id field, and the documentation explains that this follows JSON-RPC notification semantics.
The difference has nothing to do with whether data is structured, whether encryption is enabled, or which transport is used. Both requests and notifications can carry structured JSON parameters. Security belongs to the transport/authentication layer, while MCP can transmit JSON-RPC messages over supported transports such as STDIO or Streamable HTTP.
Therefore, B is the precise protocol-level distinction.

問題 #43
Which prompt addition is used for zero-shot Chain-of-Thought prompting?
答案：C
解題說明：
Zero-shot Chain-of-Thought prompting encourages a language model to decompose a problem into intermediate reasoning steps without supplying worked examples in the prompt. The classic prompting addition associated with this technique is "Let's think step by step." The technique is "zero-shot" because the user does not provide demonstrations showing how comparable problems should be solved; instead, a short natural-language instruction encourages stepwise decomposition.
OpenAI's published prompting guidance historically illustrates this exact technique, explaining that instructing a model to reason through a sequence of steps can improve performance on tasks requiring decomposition. The OpenAI Cookbook specifically gives "Let's think step by step" as an example of an instruction used to elicit a series of reasoning steps.
Setting temperature to zero affects sampling variability rather than creating Chain-of-Thought prompting.
Uploading structured data is unrelated to the reasoning technique, and disabling retrieval tools changes the model's information-access environment rather than prompting its problem-solving structure.
Accordingly, C is the intended and technically correct answer. The uploaded source also marks this exact phrase as correct.

問題 #44
Assume an agent has access to the tools multiply(a, b) and divide(a, b). A user asks: "What is 15 multiplied by
8, then divided by 3?" In the OpenAI Agents SDK, how does the agent loop handle this multi-step task?
答案：C
解題說明：
The OpenAI Agents SDK implements an iterative agent loop in which the model determines which available capability should be invoked, receives the resulting observation, and can then make another tool call based on that updated context. Consequently, the model first requests multiply(15, 8) . The function executes and returns 120 ; that tool output is supplied back to the model. The model then determines that the remaining operation requires divide(120, 3) and requests the second tool.
OpenAI describes Agents as LLMs equipped with tools and explains that the SDK runtime manages repeated model/tool interactions until the workflow produces final output. Function tools expose schemas and executable implementations to this orchestration process.
The Runner is responsible for coordinating the loop; it does not independently substitute its own arithmetic logic for the model's tool decisions. Similarly, the SDK does not synthesize a new combined function when two distinct tools are required, nor does it invoke every available tool without reason.
The uploaded question source explicitly marks the sequential multiply-then-divide behavior as correct.

問題 #45
Which tasks is handled automatically by LangChain when using agent.invoke()?
答案：D
解題說明：
When a LangChain agent is invoked through agent.invoke() , the agent runtime abstracts the core mechanics required for model-mediated tool execution. LangChain tools expose structured inputs and outputs, and tool definitions provide the model with schemas derived from Python type information or explicitly supplied schemas. The framework then coordinates model responses containing tool calls, dispatches the corresponding tools, passes observations back to the model, and repeats the process until the agent reaches a termination condition.
This is a major distinction between directly binding tools to a standalone chat model and using a LangChain agent. LangChain documentation states that, with a model alone, the developer must execute returned tool calls and feed results back manually; when an agent is used, the agent loop handles that tool-execution loop .
Thus, the course's intended abstraction is captured by B: building/exposing tool schemas, processing model tool calls, and orchestrating iterative execution. GPU memory distribution and model training are infrastructure/model-development responsibilities, not functions of agent.invoke() .
The supplied question source explicitly marks B as the expected answer.

問題 #46
When is MCP most valuable?
答案：D
解題說明：
MCP delivers its greatest architectural value when an AI application must interact with capabilities that exist outside the application's own process , particularly external services, databases, SaaS platforms, APIs, or cloud-hosted tools. Instead of implementing a proprietary integration contract for every agent/tool combination, an MCP server exposes those capabilities using a standardized protocol.
The MCP specification describes the protocol as a standardized mechanism for integrating LLM applications with external data sources and tools . Its tools specification further states that MCP servers can expose capabilities that query databases, call APIs, perform computations, or otherwise interact with external systems.
For trivial local functions such as add() or multiply() , a normal in-process function-tool definition is usually simpler because no separate server protocol is needed. Similarly, an application that has no external dependencies gains relatively little from introducing MCP solely for prompts or local output parsers.
Thus the decisive use case is integration across system or deployment boundaries, especially where capabilities should be reusable by multiple MCP-compatible clients.
Therefore, D is the correct answer and is also explicitly marked correct in the uploaded source.
