Which of the following statements correctly describes the difference between Recovery Time Objective (RTO) and Recovery Point Objective (RPO) in the context of disaster recovery?

RTO defines the maximum allowable downtime for a system, while RPO specifies the maximum acceptable amount of data loss measured from the point of view of time.

RTO refers to the maximum amount of data loss acceptable, while RPO specifies the maximum allowable downtime for a system.

RTO is the amount of data that can be lost during a disaster, while RPO refers to the maximum time it takes to recover from a disaster.

RTO measures the total cost of disaster recovery, while RPO measures the time taken to restore normal operations.

Correct Answer

Explanation

A solutions architect intends to conduct an AWS Well-Architected Framework Review for a workload that is scheduled to go live soon. A key stakeholder emails to explain that the team is too busy to dedicate time for the review because they are working on a tight timeline before the launch. Which is the best response?

Explain that it is better to understand potential issues before the launch. Even though they may not be able to implement all changes before going live, it will help the team create an action plan for the future

Explain that a review should be done in advance to provide time to identify and address issues for a smooth launch. This review will identify any potential risks that may happen during launch. If there are too many identified, the team can opt to push back the launch date

Escalate this to a manager to get more resources assigned to the project

Push the review until after the product goes live so the team gets more time to engage
