The team is consistently delivering work late, causing schedule delays. The project manager suspects the initial duration estimates were too optimistic. What is the best action to improve future estimation accuracy?","explanation":"Reviewing historical data and lessons learned from similar projects (Option A) directly addresses the root cause of inaccurate estimates by leveraging empirical evidence from past work. This aligns with the PMI's iterative estimation approach, where actual performance data (e.g., velocity from previous sprints) is used to calibrate future estimates, improving accuracy over time. In software development, this is analogous to using historical cycle times or story point completion rates to refine planning poker sessions.","domainId":null,"difficulty":"medium","questionType":"multiple_choice","pbqConfig":null,"exhibitText":null,"options":[{"id":"4d6f0fae-7cef-4acf-b551-c45496d02162","label":null,"text":"Review historical data and lessons learned from similar projects.","isCorrect":true},{"id":"6236a28c-0c29-4c11-b5f0-42175d1d812e","label":null,"text":"Extend the project schedule to accommodate delays.","isCorrect":false},{"id":"49344fb4-a6e3-4cc2-b8e5-a516418e722d","label":null,"text":"Assign additional team members to complete tasks faster.","isCorrect":false},{"id":"86ca4d75-b96d-4090-acd7-77f3779f16b1","label":null,"text":"Increase all future estimates by 20% to account for unknowns.","isCorrect":false}],"domainName":null,"domainSlug":null},{"id":"5ec19000-6809-4b8d-b7a9-142737a7cdb5","slug":"refer-to-the-exhibit-a-developer-deployed-a-new-version-of-3n9l4","questionText":"Refer to the exhibit. A developer deployed a new version of an application to production. After restarting the service, the application fails to connect to the database. What is the most likely cause?","explanation":"The exhibit shows that the connection string in the application configuration explicitly references the 'SalesDB' database and uses the 'app_user' account. The error message indicates a login failure for user 'app_user', which in SQL Server typically means the login succeeded at the server level but the user lacks a mapped database user or the CONNECT permission on the specified database.
