Anthropic Claude Certified Developer-Foundations Sample Questions (Q59-Q64):

NEW QUESTION # 59
Your Claude application runs long agentic workflows where the agent makes many tool calls, and the conversation history grows quickly. After about 20 tool calls, you notice the agent's responses become less focused and sometimes ignore earlier task constraints.
How would you address this?

A. Remove tool calling from the workflow entirely so the agent operates as a single text-generation step with no tool outputs accumulating in the context window.
B. Restart the agent every five tool calls to prevent any drift, with the agent losing all task state at each restart point during the workflow.
C. Apply context engineering techniques such as tool output pruning or compaction to keep the active task state visible while reducing the volume of older content.
D. Increase the model's context window so the agent can hold every tool output at full detail across the entire workflow no matter how many tool calls it accumulates.

Answer: C

Explanation:
Option B addresses the actual architectural failure: low-value historical material is crowding out the high- signal information required for current reasoning. A larger context window does not guarantee better attention to important constraints. Effective agent architecture actively manages what remains in context as the workflow progresses.
Anthropic's Context Editing documentation explicitly provides tool-result clearing for agentic workflows with heavy tool usage. Once Claude has processed an older result, verbose file contents, search output, or API responses may no longer need to remain in full. Older results can therefore be removed while recent and important state remains available. Anthropic also documents compaction, where accumulated history is summarized and replaced with a smaller representation that preserves important task state.
A removes an important agent capability rather than solving context growth. C retains all accumulated noise and merely gives it more space. D repeatedly destroys valuable task state and creates artificial workflow boundaries.
Therefore, B preserves goals, decisions, unresolved constraints, and necessary results while reducing irrelevant historical content. Relevant Study Guide topics: context engineering, tool-result clearing, compaction, long-running agents, context quality, and task-state preservation.

NEW QUESTION # 60
You are integrating Claude into an application written in Python. The Claude SDK provides a Python client that wraps the underlying REST API.
How would you integrate the SDK?

A. Use the Claude Python SDK and let it handle authentication, retries, and response parsing through its standard documented patterns for Python integrations.
B. Skip the SDK and embed Claude calls in shell commands invoked from Python, so that the application runs the calls outside the main Python process.
C. Call the REST API directly with raw HTTP requests so the application avoids the SDK's abstraction between the application code and the API.
D. Use a different LLM provider's SDK and translate the responses into Claude's API shape so the application can switch providers in the future.

Answer: A

Explanation:
Option B is correct because the official Anthropic Python SDK is the supported abstraction for calling the Claude REST API from Python. Anthropic documents both synchronous and asynchronous clients, standardized request/response objects, streaming support, error classes, timeouts, request IDs, and built-in retry behavior for common transient failures. Using those documented primitives reduces boilerplate and keeps integration behavior aligned with the API.
Option A is technically possible, but it unnecessarily reimplements authentication headers, serialization, error mapping, retries, timeouts, and response handling that the SDK already provides. Direct HTTP is appropriate only when there is a specific reason not to use the supported client. Option C introduces another provider's abstraction and a translation layer that is unrelated to the stated requirement and increases compatibility risk.
Option D invokes shell commands from Python, creating needless process-management, security, and error- handling complexity.
The correct engineering principle is to use the highest-level supported client that satisfies the application's requirements while retaining access to lower-level HTTP controls when genuinely needed. Therefore, B is the appropriate Claude integration pattern. Relevant Study Guide topics: Python SDK, REST abstraction, authentication, retries, exceptions, response parsing, synchronous/asynchronous clients, and maintainable API integration.

NEW QUESTION # 61
A teammate has asked how the Claude SDK handles transient API errors, such as a temporary network issue or a brief rate-limit response. They want to know whether the application code needs to handle every transient error or whether the SDK provides any default behavior.
How would you describe the SDK's default behavior?

A. The SDK provides default retry behavior for many transient errors, and the application code can configure or extend that behavior as needed.
B. The SDK provides default retry behavior for transient errors up to a fixed number of attempts, and this behavior is not configurable.
C. The SDK provides default retry behavior for network errors but surfaces rate-limit responses directly to the application code, which must implement its own retry logic for those cases.
D. The SDK logs transient errors to a default error stream and continues execution without retrying, leaving the application code responsible for detecting and responding to failed calls.

Answer: A

Explanation:
Option D precisely matches Anthropic's SDK behavior. Official SDK documentation states that transient conditions are automatically retried two times by default with exponential backoff. The default retry set includes connection failures, HTTP 408 Request Timeout, 409 Conflict, 429 Rate Limit, and 5xx server errors. Developers can alter or disable this behavior through the SDK's retry configuration.
This directly eliminates A because the retry count is configurable. B is incorrect because rate-limit responses are among the conditions automatically retried by the supported SDKs; the API also provides retry-after information where applicable. C is incorrect because the SDK does not merely log these failures and continue without attempting recovery.
Application-level handling is still necessary after the configured retry policy is exhausted. Production code should distinguish permanent errors from transient failures, preserve request IDs for diagnostics, and decide whether higher-level fallback, queuing, or user-visible failure handling is appropriate.
Therefore, D correctly characterizes the SDK abstraction: useful retry defaults combined with developer control. Relevant Study Guide topics: Claude SDKs, transient errors, HTTP 429, retries, exponential backoff, configuration, and resilient API integration.

NEW QUESTION # 62
Your Claude application's API keys are stored in a secrets manager. The team is debating whether the same key should be used in development, staging, and production environments.
How would you handle the keys across environments?

A. Use the same key across all environments for simplicity and treat the propagation of any compromise as a known operational tradeoff for the team's key management approach.
B. Use distinct keys for each environment so a compromise in one environment does not affect the others during normal operation across the application's lifecycle.
C. Rotate the same key across environments at random intervals on the grounds that random rotation provides isolation between environments without requiring distinct keys.
D. Use a single development key everywhere on the grounds that production keys are too risky to deploy across the application's three environments during normal operation.

Answer: B

Explanation:
Option A provides proper environment isolation and credential blast-radius control. Development, staging, and production represent different trust boundaries and should not share the same API credential. If a development machine, CI job, or staging service is compromised, a distinct credential prevents the attacker from automatically gaining the same access to production.
Anthropic's official workspace documentation explicitly recommends using separate workspaces for development, staging, and production. Workspaces can have their own API keys, members, resource limits, and usage tracking, and keys can be scoped to a specific workspace. Anthropic's authentication guidance also instructs developers to store API keys in a secrets manager, rotate them periodically, revoke suspected compromised keys, and use workspaces to scope credentials by project or environment.
B confuses rotation with isolation: rotating a credential that remains shared across all environments does not create independent security boundaries. C deliberately increases blast radius. D merely substitutes one globally shared key for another and therefore has the same architectural flaw.
The supplied exam source marks A as correct. Relevant topics: Confia Management, secrets management, API-key scoping, environment isolation, credential rotation, workspaces, least privilege, and production security.

NEW QUESTION # 63
A team has deployed a multi-agent system in which a primary agent decomposes user requests and delegates subtasks to three specialized subagents: one for data retrieval, one for analysis, and one for report generation.
In production, the team observes that subagents are making redundant tool calls, occasionally exceeding token budgets, and sometimes producing outputs that contradict each other - all of which the primary agent passes along without catching.
What is the most appropriate way to address these failures?

A. Strengthen the primary agent's management layer to enforce per-subagent tool budgets, validate outputs against a defined schema before passing them forward, and establish explicit handoff contracts between stages.
B. Collapse the three subagents into a single large-context model call that handles retrieval, analysis, and generation in one pass.
C. Give each subagent read access to the other subagents' outputs so they can identify and resolve contradictions without routing back through the primary agent.
D. Add retry logic to each subagent so that when a tool call fails, the subagent retries automatically before escalating - and configure each subagent to log its tool calls and outputs to a shared trace so the team can audit redundancy and contradictions after the fact.

Answer: A

Explanation:
C addresses the failures at the correct architectural layer: orchestration and supervision . The supplied exam item identifies C as correct. The primary agent is responsible not merely for forwarding subordinate output but for governing delegation, resource usage, stage boundaries, and result quality.
Anthropic's current guidance recommends explicit control over subagent use because excessive delegation multiplies latency and cost. Its documentation specifically supports deterministic limits on subagent spawning and SDK budget controls such as max_budget_usd. Tool contracts can also use defined input schemas and strict validation so malformed data cannot silently propagate between processing stages.
Explicit handoff contracts are equally important. Retrieval should provide an agreed structure to analysis; analysis should provide validated findings to report generation; and the manager should reject, retry, reconcile, or escalate outputs that violate those contracts.
A improves observability but mainly detects problems after they occur. B destroys context isolation and can create additional coupling. D abandons useful specialization instead of correcting deficient supervision.
Relevant Claude Developer topics: Agent Patterns, orchestrator/subagent architecture, delegation, budgets, handoff contracts, schema validation, output reconciliation, and multi-agent governance .
