Analyzing Customer Requirements for Multi-site Storage Solutions

Question

Your client has just purchased an HP 3PAR StoreServ array and wants to architect and implement a DR strategy. During a disaster, they need to be back in operation within two hours after the disaster has been declared. Declaration of a disaster is estimated to one hour. The business can afford to lose five minutes worth of data. Which RTO and RPO, defined in minutes, does the customer have?

Options

  • ARTO = 120, RP0 = 5
  • BRTO = 180, RPO = 5
  • CRTO = 180, RPO = 65
  • DRTO = 5, RPO = 120

Why each option

The customer's RTO is 120 minutes (2 hours from disaster declaration), and their RPO is 5 minutes, based on the specified recovery objectives.

ARTO = 120, RP0 = 5Correct

The Recovery Time Objective (RTO) is the maximum acceptable duration of time for an application or service to be unavailable following a disaster, which is stated as 'within two hours after the disaster has been declared,' equating to 120 minutes. The Recovery Point Objective (RPO) is the maximum acceptable amount of data loss measured in time, stated as 'can afford to lose five minutes worth of data,' which is 5 minutes.

BRTO = 180, RPO = 5

The RTO is calculated from the time the disaster is declared (2 hours), not including the 1-hour estimated declaration time; therefore, 180 minutes is incorrect.

CRTO = 180, RPO = 65

The RTO is 120 minutes, not 180, and the RPO is explicitly stated as 5 minutes, not 65 minutes.

DRTO = 5, RPO = 120

This choice incorrectly swaps the RTO and RPO values and also uses incorrect figures for the requirements.
