Oracle Updated 1z0-1127-25 Exam Questions and Answers by brielle

Comprehensive and Detailed In-Depth Explanation:

In LangChain, PromptTemplate supports any number of input_variables (zero, one, or more), allowing flexible prompt design—Option C is correct. The example shows two, but it’s not a requirement. Option A (minimum two) is false—no such limit exists. Option B (single variable) is too restrictive. Option D (no variables) contradicts its purpose—variables are optional but supported. This adaptability aids prompt engineering.

OCI 2025 Generative AI documentation likely covers PromptTemplate under LangChain prompt design.

Comprehensive and Detailed In-Depth Explanation:

Frequency penalties reduce the likelihood of repeating tokens that have already appeared in the output, based on their frequency, to enhance diversity and avoid repetition. This makes Option B correct. Option A is the opposite effect. Option C describes a different mechanism (e.g., presence penalty in some contexts). Option D is inaccurate, as penalties aren’t random but frequency-based.

OCI 2025 Generative AI documentation likely covers frequency penalties under output control parameters.

Below is the next batch of 10 questions (11–20) from your list, formatted as requested with detailed explanations. These answers are based on widely accepted principles in generative AI and Large Language Models (LLMs), aligned with what is likely reflected in the Oracle Cloud Infrastructure (OCI) 2025 Generative AI documentation. Typographical errors have been corrected for clarity.

Comprehensive and Detailed In-Depth Explanation:

Chain-of-Thought (CoT) prompting explicitly instructs an LLM to provide intermediate reasoning steps, enhancing complex task performance—Option B is correct. Option A (Step-Back) reframes problems, not emits steps. Option C (Least-to-Most) breaks tasks into subtasks, not necessarily showing reasoning. Option D (In-Context Learning) uses examples, not reasoning steps. CoT improves transparency and accuracy.

OCI 2025 Generative AI documentation likely covers CoT under advanced prompting techniques.
