Agents and WorkflowsDeveloper practice
A supervisor receives two schema-valid supplier reports. One worker says an order shipped; another says it was cancelled. Both cite records, but the supervisor publishes the first completed report. Which management change directly addresses this failure? Select one answer.
02
Agents and WorkflowsDeveloper practice
A service added a custom history adapter because its earlier SDK could not resume the required sessions. The current SDK supports resumption, but a tenant-specific retention rule still requires selective deletion. What is the best maintenance decision? Select one answer.
03
Applications and IntegrationDeveloper practice
A claims assistant must display an accepted response within four seconds at the 95th percentile. Model benchmarks show two-second generation, but the application also retrieves documents and validates extracted amounts. Which requirement definition best supports the design? Select one answer.
04
Applications and IntegrationDeveloper practice
A client receives several text deltas and then the connection closes before the completion event. It marks the extracted report as successful because some text arrived. What is the best handling? Select one answer.
05
Applications and IntegrationDeveloper practice
A batch contains custom IDs for 500 invoice requests. The importer assumes result line 12 corresponds to submitted request 12 and writes several summaries to the wrong invoice records. What should it use? Select one answer.
06
Applications and IntegrationDeveloper practice

07
Applications and IntegrationDeveloper practice
Claude Code edits a generated directory despite project guidance advising against it. The directory also has a more specific instruction file, and managed settings control write permissions. Which two checks are needed to understand the effective configuration? Select two answers.
08
Claude CodeDeveloper practice
A CI job runs a repeatable repository modernization task. It must finish without a human approving each permitted operation and must provide parseable output to the next job. The repository still needs a narrow permission boundary. Which two configuration choices fit? Select two answers.
09
Eval, Testing, and DebuggingDeveloper practice
A request trace contains a transient server error rather than an invalid payload. The user deadline allows a short recovery interval. Which two behaviors are appropriate? Select two answers.
10
Model Selection and OptimizationDeveloper practice
On representative support requests, a smaller tier meets the required quality and latency thresholds. A larger tier improves a subjective style score but costs twice as much. The customer has no style requirement beyond the accepted threshold. What selection is best justified? Select one answer.
11
Model Selection and OptimizationDeveloper practice
A candidate model improves reasoning accuracy from 90% to 94%, but an unchanged prompt now produces unacceptable report formatting on 3% of requests. Reports must pass the same format and reasoning gates as before. What is the best upgrade process? Select one answer.
12
Prompt and Context EngineeringDeveloper practice
An invoice prompt handles ordinary VAT correctly but fails on labelled credit-note examples. The team has representative credit notes and a separate unseen test set. What is the best first prompt improvement? Select one answer.
13
Security and SafetyDeveloper practice
A policy prohibits sensitive personal advice. A model-based content classifier catches many violations but misses paraphrased cases. Product wants to describe it as a deterministic guarantee because the application always calls it. What is the correct deployment assessment? Select one answer.
14
Tools and MCPsDeveloper practice
A cleanup tool offers a preview of records to delete. After a user approves that preview, the live candidate set can change. The current execute tool recomputes all candidates and deletes them. What contract best preserves the approval? Select one answer.
