Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q51-Q56):

NEW QUESTION # 51
Which is NOT a built-in memory type in LangChain?

  • A. ConversationSummaryMemory
  • B. ConversationBufferMemory
  • C. ConversationTokenBufferMemory
  • D. ConversationImageMemory

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
LangChain includes built-in memory types like ConversationBufferMemory (stores full history), ConversationSummaryMemory (summarizes history), and ConversationTokenBufferMemory (limits by token count)-Options B, C, and D are valid. ConversationImageMemory (A) isn't a standard type-image handling typically requires custom or multimodal extensions, not a built-in memory class-making A correct as NOT included.
OCI 2025 Generative AI documentation likely lists memory types under LangChain memory management.


NEW QUESTION # 52
In the simplified workflow for managing and querying vector data, what is the role of indexing?

  • A. To compress vector data for minimized storage usage
  • B. To categorize vectors based on their originating data type (text, images, audio)
  • C. To map vectors to a data structure for faster searching, enabling efficient retrieval
  • D. To convert vectors into a non-indexed format for easier retrieval

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Indexing in vector databases maps high-dimensional vectors to a data structure (e.g., HNSW,Annoy) to enable fast, efficient similarity searches, critical for real-time retrieval in LLMs. This makes Option B correct. Option A is backwards-indexing organizes, not de-indexes. Option C (compression) is a side benefit, not the primary role. Option D (categorization) isn't indexing's purpose-it's about search efficiency. Indexing powers scalable vector queries.
OCI 2025 Generative AI documentation likely explains indexing under vector database operations.


NEW QUESTION # 53
Which is a key characteristic of Large Language Models (LLMs) without Retrieval Augmented Generation (RAG)?

  • A. They use vector databases exclusively to produce answers.
  • B. They cannot generate responses without fine-tuning.
  • C. They rely on internal knowledge learned during pretraining on a large text corpus.
  • D. They always use an external database for generating responses.

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
LLMs without Retrieval Augmented Generation (RAG) depend solely on the knowledge encoded in their parameters during pretraining on a large, general text corpus. They generate responses basedon this internal knowledge without accessing external data at inference time, making Option B correct. Option A is false, as external databases are a feature of RAG, not standalone LLMs. Option C is incorrect, as LLMs can generate responses without fine-tuning via prompting or in-context learning. Option D is wrong, as vector databases are used in RAG or similar systems, not in basic LLMs. This reliance on pretraining distinguishes non-RAG LLMs from those augmented with real-time retrieval.
OCI 2025 Generative AI documentation likely contrasts RAG and non-RAG LLMs under model architecture or response generation sections.


NEW QUESTION # 54
In which scenario is soft prompting especially appropriate compared to other training styles?

  • A. When the model requires continued pre-training on unlabeled data.
  • B. When there is a significant amount of labeled, task-specific data available.
  • C. When the model needs to be adapted to perform well in a different domain it was not originally trained on.
  • D. When there is a need to add learnable parameters to a Large Language Model (LLM) without task-specific training.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Soft prompting (e.g., prompt tuning) involves adding trainable parameters (soft prompts) to an LLM's input while keeping the model's weights frozen, adapting it to tasks without task-specific retraining. This is efficient when fine-tuning or large datasets aren't feasible, making Option C correct. Option A suits full fine-tuning, not soft prompting, which avoids extensive labeled data needs. Option B could apply, but domain adaptation often requires more than soft prompting (e.g., fine-tuning). Option D describes continued pretraining, not soft prompting. Soft prompting excels in low-resource customization.
OCI 2025 Generative AI documentation likely discusses soft prompting under parameter-efficient methods.


NEW QUESTION # 55
When does a chain typically interact with memory in a run within the LangChain framework?

  • A. Only after the output has been generated.
  • B. Continuously throughout the entire chain execution process.
  • C. Before user input and after chain execution.
  • D. After user input but before chain execution, and again after core logic but before output.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
In LangChain, a chain interacts with memory after receiving user input (to load prior context) but before execution (to inform the process), and again after the core logic (to update memory with new context) but before the final output. This ensures context continuity, making Option C correct. Option A is too late, missing pre-execution context. Option B is misordered. Option D overstates interaction, as it's not continuous but at specific points. Memory integration is key for stateful chains.
OCI 2025 Generative AI documentation likely details memory interaction under LangChain workflows.
