   An online bank requires an RPO of 0 seconds and an RTO of less than 5 minutes for its transaction processing system. The bank is evaluating disaster recovery strategies. Which strategy is the only one that can meet these requirements?

   • AWarm standby site with asynchronous replication and a 15-minute replication interval.
   • BCold standby site with nightly backups and a 24-hour restore process.
   • CActive-active clustering across two geographically separated data centers with synchronous data replication.
   • DPilot light strategy with asynchronous replication and automated failover.

   An e-commerce company's order processing system is hosted in a single cloud region. A risk assessment identifies a regional cloud provider outage as a high-impact, medium-likelihood event. The company's leadership accepts the risk and decides not to implement a multi-region failover solution. Instead, they allocate budget to improve the application's error handling and user messaging during an outage. This decision primarily reflects which principle?

   • ARisk transfer, where the financial impact is shifted to an insurance provider.
   • BRisk avoidance, where the company eliminates the risk by not using a single region.
   • CRisk acceptance, where the cost of mitigation exceeds the perceived benefit, so the risk is retained and managed through other means.
   • DRisk mitigation, where controls are implemented to reduce the likelihood or impact of the risk.

   A logistics company is evaluating a new high-availability solution for its shipment tracking system. The solution costs $120,000 to implement and $10,000 per year to maintain. The company estimates that without the solution, a major system outage would cost $500,000 in lost revenue and penalties. The probability of such an outage occurring in any given year is 10%. What is the expected annual ROI of implementing this solution, calculated as (annual benefit - annual cost) / annual cost?

   • A150%
   • B10%
   • C400%
   • D47%

   A regional hospital network is designing a new disaster recovery solution. The finance department wants to minimize upfront capital investment, while the IT department requires predictable monthly costs for budgeting. The solution must include a secondary data center with replicated servers and storage. Which procurement model best satisfies both departments' constraints?

   • ABuild a new data center on existing hospital land, spreading the construction cost over a 10-year depreciation schedule.
   • BLease the secondary data center space and servers on a monthly subscription, paying for compute and storage as operational expenses.
   • CUse a colocation facility with a 5-year prepaid contract to secure lower rates.
   • DPurchase the secondary data center facility and all hardware outright, capitalizing the entire cost.
