   A company has a BC/DR plan that includes a hot site for its critical application. The hot site is fully equipped and can take over within minutes. However, the company's BIA indicates that the application can tolerate up to 4 hours of downtime (MTD). The CFO suggests downgrading the hot site to a warm site to save costs, because the warm site can be operational within 2 hours. What is the most important consideration in this decision?

   • AThe MTD is irrelevant because the hot site is already in place.
   • BThe warm site's 2-hour RTO still meets the 4-hour MTD, so the downgrade is acceptable if the RPO is also met.
   • CThe warm site cannot meet the RPO because it takes longer to bring online.
   • DThe hot site is always better because it provides faster recovery, regardless of cost.

   A government agency is developing a BC/DR plan. The BIA identifies the citizen services portal as critical with an RTO of 4 hours and an RPO of 1 hour. The agency is subject to regulations that require data to be stored within the country. The agency is considering a hybrid approach: a primary site in-country and a DR site in another country. Which factor is most critical when evaluating this approach?

   • AThe cost of the DR site in another country is too high, so the agency should use a single site.
   • BThe DR site in another country may violate data residency regulations, so the agency must ensure that data is replicated in a compliant manner.
   • CThe RTO of 4 hours is too short for a DR site in another country, as network latency may prevent timely failover.
   • DThe RPO of 1 hour is too aggressive for a DR site in another country, as replication may not be fast enough.

   A financial trading firm has a BIA that identifies its trading platform as critical with an RTO of 30 minutes and an RPO of 5 minutes. The firm currently uses synchronous replication to a secondary site, which meets the RPO. However, the secondary site is in the same city and could be affected by the same regional disaster. The firm is considering adding a third site in another region. Which trade-off is most critical when deciding on the third site?

   • AThe cost of the third site versus the benefit of geographic redundancy, which protects against regional disasters.
   • BThe RTO of 30 minutes versus the RPO of 5 minutes, as the third site must meet both.
   • CThe choice between a hot site and a warm site, as a hot site is more expensive but provides faster recovery.
   • DThe need for synchronous replication versus asynchronous replication, as synchronous is more expensive.

   A company is required by its industry regulator to maintain a BC/DR plan and test it annually. The company has a limited budget and must choose between conducting a full-scale test that is expensive but provides the most realistic validation, or a tabletop exercise that is cheaper but less realistic. The regulator requires that the plan be 'tested' but does not specify the method. What is the most appropriate decision?

   • AConduct only the full-scale test because it is the only valid way to meet the regulator's requirement.
   • BConduct only the tabletop exercise every year because it is cheaper.
   • CConduct a tabletop exercise this year, and plan a full-scale test for the next year, documenting the rationale.
   • DSkip testing this year to save money, and test next year.
