DRI Disaster Recovery Strategies & Techniques 2

Question 1

Which DR strategy involves maintaining a fully operational duplicate of the primary site that is always running and can accept failover instantly?

Accepted Answer

Hot site

Answer

A hot site is a fully equipped, always-on duplicate facility that enables near-instant failover with minimal data loss.

Question 2

What is the primary purpose of a Tabletop Exercise in disaster recovery?

Accepted Answer

To walk stakeholders through scenarios in a discussion-based format

Answer

A tabletop exercise is a facilitated, discussion-based session where team members review their roles and responses to a hypothetical scenario without activating actual DR systems.

Question 3

In DR planning, 'Maximum Tolerable Downtime' (MTD) is best defined as:

Accepted Answer

The longest period a business function can be unavailable before causing irreversible harm

Answer

MTD defines the upper boundary of acceptable downtime before an organization suffers consequences it cannot recover from, setting the ceiling for RTO.

Question 4

Which technique synchronizes data to a remote site continuously so that the recovery point is essentially zero data loss?

Accepted Answer

Synchronous replication

Answer

Synchronous replication writes data to both the primary and secondary sites simultaneously, ensuring zero data divergence and near-zero RPO.

Question 5

A company's RPO is set at 4 hours. What is the MAXIMUM acceptable interval for automated data backups?

Accepted Answer

4 hours

Answer

The backup interval must not exceed the RPO; if RPO is 4 hours, backups must run at least every 4 hours to avoid exceeding allowable data loss.
