Question 170
An enterprise architecture team faces this design requirement: Financial backups must survive destruction of the primary application account by a compromised administrator. What is the most appropriate design for this workload?
Explanation
Correct Answer
Cross-account backup isolation reduces the effect of compromise of an application account. The required architecture outcome is: Financial backups must survive destruction of the primary application account by a compromised administrator. Validate this choice by checking that Backups remain recoverable from the dedicated account even when the application account is disabled.
Incorrect Answers
Backup images exist but no continuously replicated recovery environment or launch plan is configured. The specific problem here is that every backup copy resides in the same administration boundary as the threatened workloads.
All accounts share one indiscriminate service-control policy despite different risk profiles. The specific problem here is that every backup copy resides in the same administration boundary as the threatened workloads.
Only source-region S3 versioning is enabled, but no replication rule or role exists. The specific problem here is that every backup copy resides in the same administration boundary as the threatened workloads.
