Questions and Answers

What is the main purpose of implementing fault tolerance control in a system?

To rely on operator errors for better system performance

To intentionally introduce hardware failures for testing purposes

To increase the likelihood of total system failure

To ensure no single point of potential system failure exists (correct)

What is one of the technologies mentioned in the text that helps maintain fault tolerance in a system?

Overclocking processors

Redundant arrays of independent disks (RAID) (correct)

Memory speed optimization

Increasing network bandwidth

How does RAID technology help in maintaining fault tolerance?

By ensuring that all data is stored on a single disk only

By limiting data redundancy to save disk space

By intentionally deleting data to reduce system load

By automatically reconstructing lost data from redundant components on other disks (correct)

Study Notes

Auditor must verify physical security controls adequacy for protecting the organization from physical exposures.
Insurance coverage on equipment must be adequate to compensate for destruction or damage to the computer center.
Audit procedures include tests of physical security controls, such as tests of physical construction, fire detection system, access control, and RAID.
Physical construction tests involve ensuring the computer center is built with fireproof material and has proper drainage for water damage.
Fire detection system tests include confirming the presence of fire detection and suppression equipment, testing, and reviewing fire marshal records.
Access control tests involve restricting routine access to authorized employees, reviewing access logs, and observing access processes covertly.
RAID tests involve determining if the level of RAID is adequate for the organization's business risk associated with disk failure.
Fault tolerance is crucial for system operation in case of hardware failure, application error, or operator error.
Fault tolerance technologies include Redundant Arrays of Independent Disks (RAID) and Uninterruptible Power Supplies (UPS) to prevent data loss and system crashes during power outages.
