CTO Business Continuity & Disaster Recovery 2

Question 1

What characterizes a 'warm standby' disaster recovery configuration?

Accepted Answer

A scaled-down but functional replica that can be scaled up rapidly when needed

Answer

A fully operational duplicate with real-time data replication and immediate failover capability

Answer

An empty facility with only basic utilities available for equipment setup

Answer

A cloud-based snapshot of production systems refreshed on a weekly schedule

Question 2

In cloud-based DR architectures, what does the 'pilot light' approach refer to?

Accepted Answer

A minimal core infrastructure kept running that can be rapidly scaled during recovery

Answer

A real-time mirroring of all production systems to a cloud region

Answer

A notification system that alerts recovery teams when disasters are detected

Answer

A full duplicate environment kept in a powered-off state in the cloud

Question 3

What does Mean Time To Recovery (MTTR) measure in IT operations and BC/DR programs?

Accepted Answer

The average time required to restore a failed system to normal operation

Answer

The maximum acceptable period of disruption for a critical business function

Answer

The interval between scheduled preventive maintenance windows

Answer

The frequency of backup creation and validation cycles

Question 4

What is the CTO's primary responsibility in enterprise BC/DR planning and governance?

Accepted Answer

Ensuring technology resilience strategies align with business continuity requirements and risk tolerance

Answer

Writing detailed step-by-step technical recovery runbooks for all systems

Answer

Negotiating cyber insurance policies and determining coverage limits

Answer

Managing physical security protocols at all backup and recovery sites

Question 5

What is the key objective of a tabletop exercise in an organization's BC/DR testing program?

Accepted Answer

To identify gaps and weaknesses in recovery plans through scenario-based discussion

Answer

To physically test the failover of production systems to backup infrastructure under load

Answer

To verify the integrity of backup data through full restoration to a test environment

Answer

To formally certify that all recovery team members meet qualification requirements

Question 6

Which international standard specifically addresses the requirements for Business Continuity Management Systems (BCMS)?

Accepted Answer

ISO 22301 — Business Continuity Management Systems

Answer

ISO 27001 — Information Security Management Systems

Answer

NIST SP 800-53 — Security and Privacy Controls

Answer

ISO 9001 — Quality Management Systems

Question 7

What is the correct distinction between 'failover' and 'failback' in disaster recovery operations?

Accepted Answer

Failover switches workloads to backup systems; failback returns operations to the primary system after recovery

Answer

Failover applies to hardware failures only; failback applies to software or application failures

Answer

Failover is always an automated process; failback is always performed manually

Answer

Failover is used for planned maintenance windows; failback is used for unplanned outage recovery
