Oracle Agentic AI Foundations Associate 1z0-1157-26 Prüfungsfragen mit Lösungen (Q28-Q33):

28. Frage
In a production MCP architecture, where are tool implementations hosted?

A. Inside the LLM's training weights.
B. On a separate MCP server.
C. In the MCP client application that invokes the tools.
D. Hardcoded inside the agent file using @tool decorators.

Antwort: B

Begründung:
In MCP architecture, executable capabilities are exposed by an MCP server . The server advertises available tools through the protocol, including each tool's name, description, and input schema. An MCP client discovers those capabilities using tools/list and invokes a selected tool through tools/call . The uploaded course material therefore correctly identifies the separate MCP server as the location associated with production MCP tool implementations.
The official MCP architecture defines an MCP server as the program that provides context and capabilities to MCP clients. It also defines tools as executable functions exposed by servers for actions such as API calls, database queries, or file operations. During execution, the AI application routes the model-generated tool call through the corresponding MCP client to the appropriate MCP server.
Tools are not encoded into an LLM's trained weights. Locally defined function tools can indeed be declared in agent code, but that is distinct from an MCP-served tool. Likewise, the MCP client handles communication and protocol coordination; it is not conceptually the server-side implementation host.
Therefore, A is architecturally correct.

29. Frage
Which statement describes an LLM-based AI agent?

A. A newly trained standalone model type.
B. A chatbot interface with additional visual components.
C. A specialized transformer architecture.
D. A model-based system that uses tools and orchestration.

Antwort: D

Begründung:
An LLM-based AI agent is not simply a foundation model or chatbot user interface. It is a system in which an LLM acts as a reasoning and decision-making component while an orchestration layer gives it access to instructions, tools, state, external information, and potentially other agents. This architecture enables the system to decide which actions to perform and in what sequence to pursue a defined objective.
OpenAI describes an agent as an LLM equipped with instructions, tools, and handoffs, allowing it to plan, use tools to gather information or take actions, and delegate tasks when appropriate. Oracle similarly explains that AI agents use tools to communicate with external systems and dynamically determine which tools or integrations to use and in which order to achieve a goal.
An agent therefore does not require training an entirely new model architecture. The underlying LLM may be an existing pretrained model. What makes the system agentic is the combination of model reasoning with orchestration, tool execution, observations, state, and iterative decision-making.
Accordingly, D provides the correct architectural definition and matches the answer supplied in the uploaded source.

30. Frage
What is the purpose of the Vector Stores API?

A. Indexing and retrieving data by meaning.
B. Streaming video into AI agents.
C. Encrypting Object Storage buckets.
D. Translating text between languages.

Antwort: A

Begründung:
The Vector Stores API provides infrastructure for ingesting content and retrieving the portions that are semantically relevant to a query. Files associated with a vector store can be chunked and prepared for vector- based retrieval, allowing applications and agents to locate content based on semantic similarity rather than only exact lexical matches .
OpenAI's official Vector Stores API supports searching a vector store with a natural-language query and returns relevant content chunks together with similarity scores. The API also supports attaching files to vector stores and configuring the chunking strategy used during ingestion. This architecture is foundational to retrieval-augmented generation and File Search workflows: source material is indexed, a user query retrieves semantically related chunks, and those chunks can then provide grounded context to a model.
Language translation is a generative-model task. Object Storage encryption is a cloud-storage security function, while video streaming is unrelated to the purpose of a vector store.
Accordingly, "Indexing and retrieving data by meaning" is the technically correct description and is also the answer specified by the uploaded question source.

31. Frage
According to the MCP architecture model, which statement describes the client-server relationship?

A. An MCP client maintains a dedicated connection to an MCP server.
B. MCP clients and servers run on separate machines.
C. An MCP server is used by one client during its lifetime.
D. A single MCP client communicates with multiple servers through one shared MCP connection.

Antwort: A

Begründung:
MCP follows a host-client-server architecture in which the host creates an MCP client for each MCP server it connects to. The official architecture specifies that each MCP client maintains a dedicated connection with its corresponding MCP server . A host connecting to several servers therefore normally manages several MCP client instances rather than multiplexing all servers through one shared client connection. MCP also does not require clients and servers to reside on different machines. STDIO-based servers commonly execute locally, while Streamable HTTP supports remotely deployed servers. Likewise, a remote MCP server can serve many MCP clients, so a server is not permanently restricted to one client. This client-server separation is particularly relevant to OCI Enterprise AI Agents because MCP Calling enables OCI agent workflows to consume capabilities exposed by remote MCP servers through a standardized integration model.

32. Frage
In the OpenAI Agents SDK, when are input guardrails and output guardrails evaluated?

A. Input guardrails run before the agent processes input; output guardrails run before the response is returned.
B. Input guardrails and output guardrails both are evaluated only after the final response is generated.
C. Input guardrails and output guardrails both are evaluated only before the model receives user input.
D. Input guardrails and output guardrails run only if explicitly triggered by the model.

Antwort: A

Begründung:
The Agents SDK separates validation at the input and output boundaries of an agent workflow. Input guardrails evaluate the initial user input, while output guardrails evaluate the final agent output before that result is accepted and returned. This makes B the intended architectural answer. A technical nuance is that current SDK input guardrails support both blocking and parallel execution: with blocking execution, validation completes before agent execution starts; with the default parallel mode, the guardrail can execute concurrently with the agent. Output guardrails, however, operate on the completed final output and always execute after the agent finishes producing it. Guardrails are runtime controls rather than decisions the LLM must explicitly request. OCI's agentic architecture similarly emphasizes governed model-and-tool workflows, making these validation boundaries important when implementing production AI agents. OpenAI GitHub
