Which of the following recovery strategies should a company implement to ensure data center services are quickly restored and accessible after a disaster occurs?
The correct answer is B. Active-passive approach. CompTIA Network+ N10-009 includes high availability and disaster recovery concepts such as failover, redundancy, and recovery strategies. An active-passive approach uses a primary production system, site, or service that actively handles traffic, while a secondary standby environment remains ready to take over if the primary environment fails. This design helps ensure data center services can be restored and made accessi ble quickly after a disaster because the standby environment is already planned and prepared for failover.
Backup and replication software is important for data protection, but backups alone do not guarantee that services will be quickly available. Restoring systems from backups may require significant time. Cloud computing can support disaster recovery, but it is a broad deployment model rather than a specific recovery strategy. Remote manual failover can restore services, but manual failover usually takes longer and increases the chance of administrative delay or error.
Because the question emphasizes quickly restored and accessible services after a disaster, an active-passive approach is the most appropriate option. It provides a standby recovery environment designed to assume operations when the active data center service becomes unavailable.
