Question 1

Which backup strategy minimizes storage space and backup window duration but results in the longest restore time?

Accepted Answer

Incremental backup

Answer

Incremental backups capture only changes since the last backup of any type, making them fast and small, but restoration requires chaining together all incremental sets since the last full backup.

Question 2

A manufacturing company identifies that losing its ERP system for more than 8 hours will result in regulatory fines and production shutdowns. This finding comes from which process?

Accepted Answer

Business Impact Analysis (BIA)

Answer

A Business Impact Analysis (BIA) quantifies the operational, financial, and regulatory consequences of disruptions to identify critical systems and their time-sensitivity.

Question 3

What does 'split-brain' refer to in the context of high-availability clustering?

Accepted Answer

A situation where two cluster nodes both believe they are the active primary and make conflicting changes

Answer

Split-brain occurs when cluster nodes lose communication and both assume primary status, potentially causing data corruption; quorum mechanisms are used to prevent it.

Question 4

An organization implements replication with a 30-minute lag to the DR site as a deliberate design choice. What specific threat does this protect against?

Accepted Answer

Ransomware or logical corruption that would otherwise replicate immediately to the DR site

Answer

A deliberate replication lag creates a window of clean data at the DR site, ensuring that ransomware encryption or logical corruption doesn't instantly overwrite the DR copy.

Question 5

Which DR document specifically captures the names, roles, and contact information of all personnel responsible for executing the recovery plan?

Accepted Answer

Call tree / contact roster

Answer

A call tree (also called a contact roster or notification list) documents who needs to be contacted during a disaster, in what order, and via what method.
