NEW QUESTION # 79
You are designing a Claude application that helps medical researchers analyze multi-step clinical case studies.
The application must work through differential diagnoses by considering symptom patterns, weighing evidence across competing hypotheses, and showing intermediate reasoning steps before producing a final recommendation. The team is choosing among Claude's available model options.
The model option best suited to this use case is...
Answer: D
Explanation:
Option B is the best answer because the task requires deliberate multi-step reasoning over competing hypotheses before a final recommendation. Anthropic's thinking documentation explains that enabling thinking gives Claude additional reasoning capacity before producing the final response, and larger thinking budgets can improve performance on complex analytical tasks. That maps directly to a differential-diagnosis workflow involving evidence comparison, hypothesis elimination, and multi-stage synthesis.
Option A uses ordinary zero-shot prompting and does not specifically allocate additional reasoning capacity.
Option C explicitly optimizes for minimum latency at the expense of reasoning depth, which conflicts with the complexity requirement. Option D reduces model and context capacity and therefore has no principled relationship to better differential reasoning.
One current-platform nuance is important: manual "extended thinking" is the legacy configuration on supported Claude 4.5/4.6 models, while newer models use adaptive thinking. That does not change the question's underlying answer: among the listed choices, B is the only option that intentionally provides a reasoning phase for complex analysis. Relevant Study Guide topics: thinking, reasoning budgets, complex- task model configuration, latency-quality tradeoffs, and model selection.
NEW QUESTION # 80
A teammate is debugging a Claude application whose system prompt has grown to several hundred lines and now contains overlapping, contradictory, and obsolete instructions.
How would you advise the teammate?
Answer: D
Explanation:
Option B is correct. A large prompt containing overlapping, contradictory, or obsolete instructions creates instruction ambiguity and increases the likelihood that Claude will apply an unintended rule, over-weight irrelevant guidance, or produce inconsistent behavior.
Anthropic's current prompting guidance reinforces this principle: Claude performs best when instructions are clear, explicit, and direct. Prompt design should minimize ambiguity and provide the model with precisely the context and behavioral requirements needed for the task. Refactoring should therefore remove obsolete requirements, consolidate duplicated instructions, resolve contradictions, and establish one authoritative formulation for each behavioral rule. The revised prompt should then be regression-tested against representative inputs.
A makes an already overloaded prompt larger and relies on instruction ordering instead of eliminating conflicts. C addresses only one defect while retaining redundant and obsolete material. D does not inherently solve contradictions and may fragment authoritative instructions across multiple locations.
Therefore, B addresses the root cause. Relevant Study Guide topics: system prompt design, prompt maintainability, instruction clarity, conflicting instructions, prompt refactoring, regression evaluation, and context quality.
NEW QUESTION # 81
You are designing a Claude application that will process customer support tickets in two stages: a triage stage that classifies tickets and a response stage that drafts replies. The team is debating whether to use a single Claude call that handles both stages or separate Claude calls for each stage.
How would you structure the application?
Answer: B
Explanation:
Option C follows a prompt-chaining/workflow decomposition pattern. Ticket classification and reply generation are materially different tasks. Triage may require a constrained category, priority, or routing decision, while response generation requires richer context, tone, policy compliance, and customer-facing language. Splitting the stages allows each Claude call to use a prompt, context set, model configuration, output format, and evaluation criterion appropriate to that specific responsibility.
Anthropic's guidance on effective agentic systems distinguishes predictable workflows from open-ended agents and recommends using the simplest architecture that meets requirements. Predefined workflows are particularly appropriate where work can be divided into clear processing stages.
This decomposition also creates useful engineering boundaries: the triage output can be validated before becoming input to the drafting stage; triage accuracy and response quality can be evaluated independently; and either stage can later be optimized without rewriting the entire process.
A unnecessarily restricts the second stage to rules. B introduces expensive parallel generation and a selection step without a stated requirement. D optimizes solely for call count while sacrificing task separation and observability.
The supplied exam source marks C. Relevant topics: Agent Patterns, prompt chaining, workflow decomposition, focused prompts, stage-level evaluation, and modular Claude application design.
NEW QUESTION # 82
You have just shipped a new Claude-powered application to production. The development phase is complete, and the system is now in active use by internal teams.
The next phase of work for this system is...
Answer: D
Explanation:
Production deployment does not terminate the software lifecycle. Once a Claude application is actively serving users, it enters an operations and maintenance phase in which developers and operators monitor performance, evaluate model behavior, respond to failures, control costs, manage security, and evolve the implementation as requirements or model capabilities change.
Anthropic's official developer documentation explicitly separates the journey into build, evaluate-and-ship, and operate stages. The operating stage includes workspace administration, API-key management, usage monitoring, and model migration. This confirms that production deployment is a transition into ongoing operation rather than the endpoint of development.
For LLM applications, maintenance is especially important because production traffic can expose input distributions and failure modes that were not fully represented during pre-release evaluation. Operational data should feed back into evaluations, prompt improvements, guardrails, architecture decisions, and model- version planning.
A incorrectly treats deployment as final. B may be useful but is only one governance activity, not the overall lifecycle phase. D assumes a mandatory organizational separation that is neither required nor generally desirable.
The supplied exam source marks C. Relevant topics: Systems Life Cycle, production operations, monitoring, maintenance, incident response, evaluation, and continuous system evolution.
NEW QUESTION # 83
A teammate has asked you to explain when a Skill would be the right choice over an MCP server. The teammate is unsure how the two differ in practice when both can be reused across teams.
How would you explain the distinction?
Answer: D
Explanation:
The supplied Claude Developer question explicitly identifies D . The two mechanisms solve different extension problems. A Skill is a reusable package of domain expertise and workflow guidance. Anthropic describes Agent Skills as modular, filesystem-based capabilities containing instructions, metadata, and optional supporting resources such as scripts and templates, which Claude can load when relevant.
MCP, by contrast, defines a standardized mechanism for exposing external capabilities and context.
Anthropic's MCP integration supports MCP tools and, through client-side helpers, MCP prompts and resources. This makes MCP appropriate when Claude must communicate with an external server or reusable service interface rather than simply load packaged expertise.
Thus, Skills are appropriate for packaging repeatable instructions, procedures, scripts, templates, or domain knowledge. MCP servers are appropriate for exposing callable operations, external data resources, and shared service capabilities using the Model Context Protocol.
A incorrectly treats them as interchangeable. B incorrectly describes the difference as merely generational. C invents a universal efficiency advantage that is not the architectural distinction.
Relevant Claude Developer topics: Agent Construction, Agent Skills, MCP, reusable capabilities, resources, prompts, tools, extension architecture, and cross-team component reuse .
