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.
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.
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.
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.
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.
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.
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.
