CCDV-F Multiple Select — 10 Questions

Question 1

An AI engineering team is auditing an expensive Claude API integration processing millions of customer support queries daily. Which TWO strategies should they implement to effectively reduce token expenditure without sacrificing core model intelligence? (Choose two)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Implement Anthropic prompt caching for large, recurring system prompts and reference knowledge bases.. Optimizing context management and leveraging prompt caching are cornerstone strategies for cost reduction in high-volume Anthropic integrations. Caching static system prompts drastically lowers input token charges across repeated requests, while concise prompts eliminate redundant verbiage. Together, these practices protect infrastructure budgets while sustaining the semantic fidelity required by enterprise-grade support workflows.

Answer

Switch every production workload immediately from Claude 3.5 Sonnet to Claude 3 Opus to maximize parallel processing.

Answer

Disable response streaming to batch full payloads and reduce HTTP connection overhead.

Answer

Hardcode maximum output tokens to five thousand across all API calls regardless of task complexity.

Question 2

A developer is designing a subagent architecture with the Claude Agent SDK. The main agent delegates a codebase audit to a specialized subagent to keep the primary conversation focused. Which TWO practices help ensure the delegation works correctly? (Choose two.)

Accepted Answer

Give the subagent a narrowly scoped task description and only the tools it needs for the audit.. Effective delegation depends on isolation and distillation. Scoping the subagent's task and tools keeps it focused and safe, while returning a concise structured summary preserves the main agent's context budget and attention. Sharing full history, granting broad tools, or dumping raw logs all reintroduce the noise that subagents are meant to filter out.

Answer

Configure the subagent with the same broad toolset as the main agent to maximize flexibility.

Answer

Have the subagent write its raw logs directly into the main agent's message history for transparency.

Answer

Share the main agent's entire conversation history with the subagent so it has maximum context.

Question 3

A developer is building a pipeline that summarizes a 200-page technical manual with Claude Sonnet. The manual is too long for a single request, so the developer splits it into 40 chunks and summarizes each chunk independently. The final summaries must remain factually consistent with one another and with the source, and the developer has a fixed token budget. Which two techniques should the developer apply to keep the chunk summaries consistent and grounded? (Choose two.)

Accepted Answer

Carry a running 'state' summary of key entities, definitions, and decisions forward into each subsequent chunk request.. Cross-chunk consistency requires either shared context or a reconciliation step. Carrying a running state forward gives each request the key facts established earlier, while a verification pass that reconciles adjacent summaries catches contradictions before they propagate. Together they maintain grounding and consistency within a bounded token budget, unlike duplicating output or resending all prior text.

Answer

Include the full text of all previously processed chunks in every new request.

Answer

Ask the model to summarize each chunk twice and concatenate both outputs to increase coverage.

Answer

Lower the temperature to zero and rely on deterministic sampling to guarantee identical facts across chunks.

Question 4

A developer wants Claude Code to run a series of shell commands as part of a build task but is concerned about the assistant executing arbitrary or destructive commands. Which TWO practices reduce this risk while still allowing the needed commands to run? (Choose two.)

Accepted Answer

Add a PreToolUse hook on the Bash tool that inspects the command and blocks anything outside the approved set.. Least-privilege controls are the right answer. An allow list in settings.json restricts execution to the specific build commands, and a PreToolUse hook on the Bash tool can inspect and block disallowed commands before they run. Together they permit the intended build while constraining arbitrary or destructive execution. Skipping permissions removes safeguards, memory-file advice is not enforced, and container hardening changes the environment rather than governing command selection.

Answer

Instruct Claude Code in CLAUDE.md to never run dangerous commands.

Answer

Run the build inside a container with no network access and a read-only filesystem.

Answer

Enable `--dangerously-skip-permissions` to avoid prompts during the build.

Question 5

A developer is building an MCP server that exposes several tools for managing a cloud infrastructure. The server will be used by multiple Claude clients. The developer wants to ensure that tool calls are handled efficiently and that the server can scale. Which two practices should the developer implement? (Choose two.)

Accepted Answer

Design tools to be idempotent where possible, so that repeated calls with the same parameters produce the same result.. The two best practices are statelessness and idempotency. Statelessness allows any server instance to handle any request, enabling horizontal scaling. Idempotency ensures that retries are safe, which is important for reliable infrastructure operations. Together, they improve efficiency and scalability. Other options like caching, global locking, or in-memory session state either introduce complexity or hinder scalability.

Answer

Cache the results of expensive tool calls on the server side and return cached responses for identical requests.

Answer

Use a single global lock to serialize all tool calls, preventing concurrent execution.

Answer

Store session state in memory on each server instance to track client interactions.

Question 6

A security auditor is reviewing an application that uses the Model Context Protocol (MCP). Which TWO security considerations are most important for the developer to address when implementing the MCP Server?

Accepted Answer

The server should strictly validate all tool arguments against its internal logic.. Security in MCP is a shared responsibility. While the protocol facilitates communication, the server developer must ensure that the tools and resources exposed do not create vulnerabilities. This includes limiting access to the file system and ensuring that tool inputs are properly validated before being used in potentially dangerous operations like shell commands.

Answer

The server must use a unique API key for every tool call it receives.

Answer

The server must rotate its connection ID every sixty seconds for privacy.

Answer

All MCP tool results must be manually approved by a human operator.

Question 7

When implementing a 'Computer Use' agent, which THREE capabilities are provided by the standardized Anthropic beta tools 'computer', 'text_editor', and 'bash'?

Accepted Answer

Capturing screenshots and performing mouse/keyboard interactions.. Anthropic provides specialized tools for computer interaction to ensure consistent behavior across different environments. These tools allow the agent to perform GUI actions, modify files with precision, and execute shell commands. Together, they form a comprehensive suite for agents that need to operate as a virtual developer or assistant on a computer system.

Answer

Rewriting entire binary files to optimize system performance.

Answer

Automatically upgrading the host operating system to the latest version.

Question 8

A developer needs to estimate the monthly budget for a new internal knowledge base application powered by Claude. Which TWO factors directly influence the total token consumption and subsequent cost of the API requests?

Accepted Answer

The total number of input tokens in the prompt. Estimating costs requires understanding the components of the billing model used by Anthropic. Total cost is derived from the volume of input tokens sent to the model and the volume of output tokens generated by the model. Developers must account for both segments because they are priced at different rates across the Claude 3 model family to reflect processing requirements.

Answer

The number of concurrent users accessing the application

Answer

The physical geographic location of the application server

Answer

The programming language used to make the API calls

Question 9

Which THREE of these actions are considered safe and standard for Claude Code to perform during an interactive session?

Accepted Answer

Reading and summarizing codebase files.. Claude Code is built with safety as a priority. It is expected to handle file editing, command execution, and code review as part of its normal operation. Understanding these standard actions allows developers to trust the agent's output and integrate it into their workflow efficiently. By focusing on safe, verified, and transparent interactions, the agent maintains its role as a helpful assistant while minimizing risks associated with uncontrolled automation in a local project.

Answer

Deleting arbitrary user files without asking.

Answer

Exfiltrating environment variables to remote servers.

Question 10

Which TWO of the following are essential components of a 'tool_use' block generated by Claude?

Accepted Answer

A unique 'id' string used to match results to the specific request.. A 'tool_use' block must contain specific identifiers so that the SDK knows which tool to run and how to track its result. The 'id' uniquely identifies the specific call in the conversation history, while the 'name' maps the call to the actual function or service defined in the agent's configuration.

Answer

The full source code of the function being called.

Answer

The 'timestamp' of when the model decided to use the tool.

Answer

The 'confidence_score' the model assigns to this specific tool call.
