Question 550
An enterprise architecture team faces this design requirement: A DynamoDB application requires recovery from accidental writes to an earlier point within a month. Which proposed change addresses the stated constraint most directly?
Explanation
Correct Answer
DynamoDB PITR restores to a selected point within its available recovery window. The required architecture outcome is: A DynamoDB application requires recovery from accidental writes to an earlier point within a month. Validate this choice by checking that Restoring a suitable past timestamp creates a usable table with correct records.
Incorrect Answers
Kubernetes deployment treats process startup as adequate evidence of request readiness. The specific problem here is that standard short-lived backups cannot recover the exact chosen accidental-update point.
Service-specific Health notifications are not routed into incident processes. The specific problem here is that standard short-lived backups cannot recover the exact chosen accidental-update point.
Availability claims rest only on architecture diagrams, not controlled chaos evidence. The specific problem here is that standard short-lived backups cannot recover the exact chosen accidental-update point.
