    GCP PCA · Question 48 · Business Requirements

    You are designing a Disaster Recovery (DR) plan for a critical application. The business stakeholders have defined a Recovery Point Objective (RPO) of 1 hour and a Recovery Time Objective (RTO) of 4 hours. Which TWO statements correctly describe what these metrics mean for your architecture? (Select TWO)

    Answer options:

    A.

    The architecture must ensure that no more than 1 hour of data is lost in the event of a disaster.

    B.

    The application must be restored and fully operational within 1 hour of a disaster.

    C.

    Database backups must be taken every 4 hours.

    D.

    The architecture must ensure that no more than 4 hours of data is lost in the event of a disaster.

    E.

    The application must be restored and fully operational within 4 hours of a disaster.

    How to approach this question

    Remember: RPO = Data Loss (Point in time). RTO = Downtime (Time to recover).

    Full Answer

    In Disaster Recovery planning, RPO (Recovery Point Objective) refers to the maximum acceptable amount of data loss. An RPO of 1 hour means backups or replication must occur at least every hour. RTO (Recovery Time Objective) refers to the maximum acceptable downtime. An RTO of 4 hours means the IT team has 4 hours from the moment of failure to spin up infrastructure, restore data, and get the application running again.

    Common mistakes

    Confusing RPO and RTO. RPO is about Data. RTO is about Time/Availability.
