IIA IIA-CIA-Part3 Based on Real Exam Environment

Comprehensive and Detailed In-Depth Explanation:

Biometric authentication (e.g., fingerprint, retina scan) is the most difficult to revoke because it is linked to an individual’s physical attributes, which cannot be changed like passwords or physical devices.

Option A (Traditional key lock) – Can be revoked by retrieving the key or changing the lock.

Option C (Card-key system) – Can be revoked by deactivating the card.

Option D (Proximity device) – Can be revoked by disabling the device.

Since biometric data is permanently tied to an individual, revoking access is complex, making Option B the correct answer.

Comprehensive and Detailed In-Depth Explanation:

Computer hardware refers to the physical components of a computer system.

Workstation: A high-performance computer designed for technical or scientific applications.

Modem: A device that modulates and demodulates signals for data transmission over communication lines.

Disk drive: A device that reads and/or writes data to a disk storage medium.

Option D lists only physical components, fitting the definition of computer hardware.

In contrast:

Value-added network (option A): A hosted service offering specialized networking services, not a physical component.

Data warehouse (option B): A system used for reporting and data analysis, representing a data storage concept rather than a physical device.

Firewall (option C): While it can be hardware, it is often implemented as software; thus, the term doesn't exclusively denote hardware.

Therefore, option D accurately represents a list of computer hardware components.
