In the recovery scenario, how many hours are allocated to OS/software recovery?

• A. 4 hours
• B. 10 hours
• C. 14 hours
• D. 24 hours

Answer: (B)

In a recovery plan, this stage covers bringing back the operating system and essential software in a clean, secure state. It isn’t about restoring data or rebuilding hardware; it’s about reinstalling the OS, installing required applications, applying patches, configuring security settings, and verifying that critical services can start and run correctly. Ten hours gives enough time to perform a thorough OS reinstall, set up the necessary software, apply updates, harden security, and run basic checks to ensure the environment is usable before moving on to more extensive validation or data restoration. Shorter windows, like four hours, would risk an incomplete reinstall, while much longer windows, like fourteen or twenty-four hours, are typically used for broader rebuilds or less time-critical scenarios.
