  1. Which type of disaster recovery site has hardware ready but requires software and data restoration before use?

    Answer: Warm site

    A warm site has pre-installed hardware and network connectivity but requires data restoration from backups, offering a balance between cost and recovery speed.

  2. What is a cold site in disaster recovery?

    Answer: A backup location with only basic infrastructure such as power and cooling

    A cold site provides only the physical space and basic utilities; all hardware, software, and data must be brought in and configured after a disaster.

  3. What is the key advantage of cloud-based backup over traditional tape backup?

    Answer: On-demand scalability and remote accessibility

    Cloud backup offers virtually unlimited scalability and allows data to be accessed and restored from anywhere with an internet connection, unlike physical tapes.

  4. What does a business continuity plan (BCP) address that a disaster recovery plan (DRP) does not?

    Answer: Maintaining business operations during and after a disruption, not just IT recovery

    A BCP covers the continuation of all critical business functions during a disruption, while a DRP focuses specifically on restoring IT systems and data.

  5. Which backup media is most vulnerable to data loss from strong magnetic fields?

    Answer: Magnetic tape

    Magnetic tape stores data using magnetic particles, making it susceptible to erasure or corruption when exposed to strong magnetic fields.

  6. What is a 'snapshot' in the context of data backup?

    Answer: A point-in-time copy of data or a system state

    A snapshot captures the state of a system or dataset at a specific moment, enabling rapid restoration to that exact point in time.

  7. When conducting a disaster recovery test, what does a 'tabletop exercise' involve?

    Answer: A discussion-based simulation where team members talk through their response to a hypothetical disaster

    A tabletop exercise is a low-cost, discussion-based walkthrough that identifies gaps in DR plans without disrupting production systems.
