What network service controls those who are permitted to access a network, what they can do while they are there, and track what actions they perform while accessing the network?

  • AAA
  • DHCP
  • DNS server
  • print server
Explanation & Hint:

The network service that controls who is permitted to access a network, what they can do while they are there, and tracks what actions they perform while accessing the network is AAA (Authentication, Authorization, and Accounting).

  • Authentication: Verifies the identity of a user or device attempting to access the network.
  • Authorization: Determines what an authenticated user or device is permitted to do on the network.
  • Accounting: Keeps track of what actions the user or device performs while on the network.

The other services mentioned have different functions:

  • DHCP (Dynamic Host Configuration Protocol): Assigns IP addresses and other network configurations to devices on a network, but doesn’t manage user access or track activities.
  • DNS (Domain Name System) Server: Translates domain names into IP addresses, and is not involved in user access control or activity tracking.
  • Print Server: Manages printers and print jobs in a network, unrelated to network access control or user activity monitoring.
