SAP-C03 practice question: Resilience assessment and testing (Resilience Hub, Fault Injection Service) (1 of 2)
Resilience, Migration, and Business Continuity A free question from our original SAP-C03 practice exam. Try it, then open the answer to see why each option is right or wrong.
A retailer has a documented recovery target for each of its 12 critical applications: a recovery time objective and a recovery point objective. The resilience team does not know which applications would actually meet those targets if a Region or an Availability Zone failed.
The team wants an assessment that compares each application's design with its targets and recommends fixes, with the results kept for the audit committee. The team does not want to break anything in production to find the answer.
Which approach meets these requirements?
Choose one answer.
AA. Run AWS Fault Injection Service experiments in production against each application, measure how long each one takes to recover, and compare the recovery times with each application's targets.
BB. Use AWS Resilience Hub with a resiliency policy that holds each application's recovery targets, assess the applications against it, and review the recommendations and stored results.
CC. Ask each application team to write a recovery plan in a shared document, and have the resilience team sign off on each plan after a review meeting.
DD. Schedule a full disaster recovery drill for each Region once a year, and record the outcome of each drill in the audit file.
Show the answer and explanation
Answer: B
A. Wrong: Production experiments can disrupt customers, which the team wants to avoid for this assessment. Measured recovery times also come without design recommendations for closing the gaps.
B. Right: Correct. Resilience Hub compares each application's design with its recovery targets and recommends fixes, and it keeps the assessment results for review. The assessment reads the design and does not disrupt production.
C. Wrong: A written plan does not test the design against the targets, and the review gives no repeatable evidence for the audit committee. The option does not meet the assessment requirement.
D. Wrong: A yearly drill is a real test but a rare one, and it disrupts the environment during the drill. It does not compare the designs with the targets or recommend fixes.
Explanation
Resilience Hub assesses each application's design against its recovery targets, recommends fixes and keeps the results, without disrupting production. Production fault experiments, written plans and yearly drills each miss the assessment, the recommendations or the no-disruption need.
