問題 #37
Why is chunking necessary before generating embeddings for large documents?
答案：C
解題說明：
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.

問題 #38
Which standard MCP transport supports remote or network-accessible deployments where multiple clients may connect?
答案：B
解題說明：
Streamable HTTP is the standard MCP transport intended for remote or network-accessible client-server communication. Current MCP architecture documentation distinguishes it from STDIO by explaining that Streamable HTTP uses HTTP POST for client-to-server communication and can optionally use Server-Sent Events for streaming. It enables communication with remote MCP servers and can support standard HTTP authentication mechanisms.
The MCP transport specification further establishes two standard transport mechanisms: stdio and Streamable HTTP . With STDIO, the client launches an MCP server as a local subprocess and exchanges JSON-RPC messages through standard input and standard output. That pattern is therefore most appropriate for local process integration. By comparison, a Streamable HTTP server operates as an independent service and can handle multiple client connections, making it suitable for centralized or cloud-hosted MCP deployments.
Raw TCP sockets and local Unix pipes are not the standard remote MCP transport defined by the protocol.
Therefore, C is correct and matches the supplied source material.

問題 #39
What is the default distance metric for VECTOR_DISTANCE in Oracle for non-BINARY vectors?
答案：B
解題說明：
Oracle AI Vector Search defines VECTOR_DISTANCE as the primary SQL function for calculating the distance between two vectors. When the function is called without explicitly specifying a distance metric, Oracle specifies COSINE as the default metric for ordinary, non-BINARY vectors. Cosine distance measures the angular relationship between vector representations and is widely used for semantic similarity because embeddings with similar meaning tend to point in similar directions in vector space. Oracle treats BINARY vectors differently: their default metric is HAMMING. Euclidean, or L2, distance is supported but must be selected when required; it is not the general default. Levenshtein distance applies to string-edit comparisons, while bitwise XOR is not the default Oracle vector-distance metric. Therefore, for the scenario stated in the question, option C is the verified answer. Oracle Docs
問題 #40
Which native column type does Oracle AI Database use for storing vector embeddings?
答案：D
解題說明：
Oracle AI Database provides a native VECTOR data type specifically for storing vector embeddings. The uploaded course source identifies VECTOR as the correct native column type.
Oracle's official AI Vector Search documentation states that the built-in VECTOR data type provides the foundation for storing embeddings directly alongside relational business data. A table can therefore define a vector column in the same way it defines conventional Oracle columns, for example doc_vector VECTOR .
This native representation is important because Oracle AI Database can apply vector-specific SQL operations and vector indexes directly to stored embeddings. Applications can combine similarity search with relational predicates, JSON processing, graph operations, spatial queries, and standard SQL without moving embeddings into a separate specialized vector database.
Although Oracle may internally use storage mechanisms such as SecureFiles for vector representation, BLOB is not the logical SQL column type developers use for AI Vector Search embeddings . JSON and VARCHAR2 are likewise general-purpose data types and do not provide native vector semantics.
Therefore, A is correct.

問題 #41
Which OCI services are used for observability and auditing of deployed AI agents?
答案：A
解題說明：
OCI production AI architectures use the standard OCI observability and governance services to provide operational visibility and accountability. OCI Logging collects and centralizes service and application logs; OCI Generative AI hosted applications can expose deployment logs that open directly in OCI Logging and the Observability and Management service. OCI Monitoring supplies metrics and alarms for monitoring resource health and operational conditions. OCI Audit records calls made to supported OCI public API endpoints, providing an authoritative record of administrative and resource-management actions for investigation and compliance. Oracle's architecture guidance specifically recommends enabling OCI Logging, OCI Monitoring, and OCI Audit logs for critical AI-platform components. The services in the other options have legitimate OCI purposes, but they do not collectively represent the principal observability-and-auditing stack. Therefore, option A is the verified combination.
