Authentic Oracle Certification Exam 1z0-1127-25 Questions Answers

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.

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.

Comprehensive and Detailed In-Depth Explanation:

Prompt templates are predefined, reusable structures (e.g., with placeholders for variables) that guide LLM prompt creation, streamlining consistent input formatting. This makes Option B correct. Option A is false, as templates aren’t complex algorithms but simple frameworks. Option C is incorrect, as templates are customizable. Option D is wrong, as they handle text, not just numbers.Templates enhance efficiency in prompt engineering.

OCI 2025 Generative AI documentation likely covers prompt templates under prompt engineering or LangChain tools.
