How many types of user accounts are defined in the material?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

When organizing access, the material groups accounts by how they’re used and what they’re allowed to do. It defines three distinct types: regular user accounts for everyday tasks, privileged or administrator accounts for configuring the system and managing other accounts, and service or application accounts used by software or automated processes. These three categories cover the typical use cases and permission levels described, so three is the right count. If you tried fewer, you’d miss either the everyday users or the automated/service accounts; more than three would introduce additional categories not described in this material.
