NEW QUESTION # 17
Which prompt addition is used for zero-shot Chain-of-Thought prompting?
Answer: C
Explanation:
Zero-shot Chain-of-Thought prompting encourages a language model to decompose a problem into intermediate reasoning steps without supplying worked examples in the prompt. The classic prompting addition associated with this technique is "Let's think step by step." The technique is "zero-shot" because the user does not provide demonstrations showing how comparable problems should be solved; instead, a short natural-language instruction encourages stepwise decomposition.
OpenAI's published prompting guidance historically illustrates this exact technique, explaining that instructing a model to reason through a sequence of steps can improve performance on tasks requiring decomposition. The OpenAI Cookbook specifically gives "Let's think step by step" as an example of an instruction used to elicit a series of reasoning steps.
Setting temperature to zero affects sampling variability rather than creating Chain-of-Thought prompting.
Uploading structured data is unrelated to the reasoning technique, and disabling retrieval tools changes the model's information-access environment rather than prompting its problem-solving structure.
Accordingly, C is the intended and technically correct answer. The uploaded source also marks this exact phrase as correct.

NEW QUESTION # 18
How do On-Demand serving and Dedicated AI Clusters differ for OCI Enterprise AI Models?
Answer: A
Explanation:
OCI Generative AI provides both On-Demand and Dedicated serving modes. The fundamental architectural distinction is resource isolation. On-Demand model inference uses Oracle-managed shared infrastructure, making it suitable for straightforward consumption of supported pretrained models without reserving dedicated hardware. Dedicated mode assigns dedicated GPU resources to the customer's workload and provides predictable, isolated serving capacity.
Oracle states that Dedicated AI Clusters are compute resources dedicated to a customer's models and are not shared with other tenancies. They are used for hosting supported pretrained models and, critically, for fine- tuning and hosting custom or imported models. The course question correspondingly identifies B as correct.
Option A ignores the infrastructure-isolation difference. Option C is technically impossible because all model inference requires compute resources; On-Demand simply abstracts shared infrastructure. Option D is also incorrect because On-Demand is not limited to embedding models-OCI provides multiple supported model categories through managed inference.
Therefore, B accurately captures both shared-versus-dedicated serving and the importance of Dedicated AI Clusters for custom-model workloads.

NEW QUESTION # 19
Which value associates OCI Responses API requests with a specific OCI Generative AI Project?
Answer: D
Explanation:
OCI Responses API requests are associated with an OCI Generative AI Project through the project's OCID - Oracle Cloud Identifier . Oracle requires an OCI Generative AI project for agent-related OpenAI-compatible API calls and uses the project identifier to determine the project context under which responses, conversations, files, containers, retention settings, and related resources operate.
Oracle's OCI Responses API documentation shows the OpenAI client configured with a project parameter containing a Generative AI Project OCID. Oracle explicitly states that this value identifies the OCI Generative AI project for the request. Oracle's project documentation further explains that projects organize agent- specific artifacts, provide isolation boundaries, and that the project OCID must be referenced in API and SDK calls to apply project settings during runtime.
An Object Storage bucket could contain data used by another workflow but does not identify the Generative AI project. The tenancy display name identifies a tenancy conceptually but not the target project. A VCN OCID refers to network infrastructure.
Therefore, D is correct and matches the uploaded answer key.

NEW QUESTION # 20
What is the strategic theme behind agentic AI capabilities in Oracle AI Database?
Answer: A
Explanation:
Oracle's strategic direction is to integrate AI capabilities directly into Oracle AI Database , allowing conventional relational data, vector embeddings, semantic retrieval, natural-language interfaces, and autonomous agent functionality to operate within the database platform rather than requiring a separate AI- only data tier.
Oracle AI Vector Search illustrates this strategy. The database provides a native VECTOR data type, vector- distance functions, vector indexes, and semantic similarity search alongside traditional relational data and SQL operations. This allows embeddings and enterprise business records to remain together under existing transactional, security, and governance controls.
Select AI reinforces the same architecture. Oracle documents that Select AI runs natively inside Autonomous AI Database and Oracle AI Database, while Select AI Agent provides autonomous reasoning, tools, reflection, memory, RAG, NL2SQL, PL/SQL integration, and REST interactions within the database-oriented agent framework.
Oracle is therefore extending SQL and database functionality rather than eliminating it. Nor is Oracle replacing the relational database with a vector-only system. The strategic objective is convergence: enterprise data plus native AI capabilities in one governed database environment. Option B is therefore correct.

NEW QUESTION # 21
Which description defines memory poisoning in AI-agent systems?
Answer: C
Explanation:
Memory poisoning is an agent-security attack in which malicious, misleading, or attacker-controlled information is introduced into memory that the agent may reuse in future reasoning or actions. The uploaded course source defines it as malicious content inserted into persistent memory stores and identifies C as correct.
Oracle's current AI Agent Memory security guidance explains why persistent memory must be treated as a security-sensitive surface. Model-derived memories, summaries, context cards, metadata, and retrieved records can become persistent state and later be inserted into prompts. Oracle therefore advises treating memory-derived content as untrusted and emphasizes that write-capable memory paths can influence future prompts and retrieval results.
The broader agent-security definition is also explicit in OWASP's Agentic AI guidance: memory poisoning involves malicious data being persisted in agent memory so that it can influence future sessions or behaviors.
This differs from temporary context-window pressure, SQL injection, or physical RAM corruption. The essential security property is persistence : compromised memory can affect later reasoning long after the original malicious interaction.
Therefore, C is correct.
