When designing a new cloudenabled application an organizatio - CompTIA CLO-002

Correct Answer: C. Disaster recovery

When designing a cloud-enabled application, considering RTO (Recovery Time Objective) and RPO (Recovery Point Objective) is most closely associated with disaster recovery planning. These two metrics are used to define the application's resilience to outages and its ability to recover from a disaster:

• RTO (Recovery Time Objective): The maximum acceptable time the application can be down after a failure.
• RPO (Recovery Point Objective): The maximum acceptable amount of data loss, defined as the time interval between backups or data replication points.

In disaster recovery planning, organizations need to ensure that their infrastructure and processes can meet these objectives in the event of a failure, whether caused by hardware failure, software issues, or other disasters.

• Why it’s correct:
  • RTO and RPO are key components of disaster recovery strategies, helping businesses plan how quickly they can restore service and how much data they can afford to lose during an outage.

Why the Other Options Are Incorrect:

Redundancy (Incorrect)

Redundancy refers to having backup systems or components in place to ensure continued service in the event of a failure, such as having backup servers or data replication. While redundancy is important for disaster recovery, it doesn’t directly focus on the time and data loss objectives that RTO and RPO measure.

• Why it’s incorrect:
  • Redundancy helps mitigate risk but doesn't specifically address recovery time and recovery point objectives, which are core to disaster recovery.

Load balancing (Incorrect)

Load balancing refers to distributing incoming traffic across multiple servers to ensure that no single server is overwhelmed. While load balancing contributes to application performance and availability, it doesn't specifically address recovery time or data loss after a failure.

• Why it’s incorrect:
  • Load balancing ensures performance and availability during normal operations, but it is not designed to handle recovery after a failure or disaster.

High availability (Incorrect)

High availability refers to ensuring that an application is operational and accessible with minimal downtime. While it helps to reduce the frequency of downtime, it is more focused on minimizing downtime in the first place rather than how long it takes to recover from an outage (RTO) or how much data may be lost (RPO).

• Why it’s incorrect:
  • High availability focuses on preventing downtime, while disaster recovery is focused on recovering from downtime when it occurs, specifically using metrics like RTO and RPO.
