   A telecommunications company's billing system has an RPO of 15 minutes. The system is currently backed up every hour. The company is considering implementing log shipping to reduce the RPO. Which statement is accurate?

   • ALog shipping increases the RPO because it adds overhead to the system.
   • BLog shipping is only useful for disaster recovery, not for meeting RPO.
   • CLog shipping does not change the RPO because the RPO is determined by the full backup frequency.
   • DLog shipping can reduce the RPO to the frequency of log backups, which can be as low as a few minutes, meeting the 15-minute RPO.

   A cloud service provider's SLA guarantees 99.95% availability for its virtual machines. A customer's VM was down for 30 minutes in a 30-day month. Did the provider meet the SLA?

   • AYes, because the SLA is measured over a year, not a month, and 30 minutes is within the yearly allowance.
   • BYes, because 30 minutes is less than the 21.6 minutes allowed for 99.95% availability in a 30-day month.
   • CNo, because 30 minutes exceeds the 21.6 minutes allowed for 99.95% availability in a 30-day month.
   • DNo, because any downtime violates the SLA, regardless of the percentage.

   How do RPO and RTO together influence the choice of data protection technology?

   • ARPO and RTO are independent and do not affect technology selection
   • BRPO and RTO only affect the storage capacity needed for backups
   • CA high RPO and high RTO require more expensive continuous replication
   • DA low RPO and low RTO typically require more frequent replication and faster recovery mechanisms

   A university's student registration system has an availability target of 99.9%. The system is down for 2 hours during a scheduled maintenance window and 30 minutes due to a power outage in a 30-day month. Did the system meet the availability target?

   • AYes, because total downtime of 2.5 hours is less than the 43.2 minutes allowed for 99.9% availability in a 30-day month.
   • BYes, because scheduled maintenance is not counted toward availability.
   • CNo, because total downtime of 2.5 hours exceeds the 43.2 minutes allowed for 99.9% availability in a 30-day month.
   • DNo, because any downtime violates the availability target.
