Difficulty: EasyWireless Security and Authentication

An IT technician is setting up a wireless network for a branch office. To prevent unauthorized devices from connecting, the technician configures the access point to require a shared passphrase that all staff members enter on their devices to gain access. Which of the following wireless security modes is being implemented?

  1. WPA2-PersonalAnswer
  2. B
    WPA2-Enterprise
  3. C
    802.1X authentication
  4. D
    RADIUS authentication

Answer

WPA2-Personal is the wireless security mode that uses a pre-shared key (PSK) or shared passphrase for authenticating all connecting devices.
WPA2-Personal (Pre-Shared Key mode) is designed for small office or home environments where all devices connect using the same shared passphrase configured on the wireless access point.

Step-by-Step Solution

1
Identify the authentication requirement in the scenario.
The requirement specifies a single shared password/passphrase entered by all users on the network.
Determining whether authentication is shared or individual distinguishes SOHO/Personal modes from Enterprise modes.
2
Match the requirement to the corresponding wireless security mode.
WPA2-Personal (PSK mode) uses a static pre-shared key for authentication across all devices.
Enterprise solutions rely on individual user credentials verified by a backend server rather than a single shared passphrase.
