Which wireless security option uses a pre-shared key to authenticate clients?
- A. WPA2-Enterprise
- B. 802.1q
- C. WPA2-Personal
- D. 802.1x
Answer: C
Explanation:
WPA2-Personal, also known as WPA2-PSK (Pre-Shared Key), is the wireless security option that uses a pre-shared key to authenticate clients. This method is designed for home and small office networks and doesn't require an authentication server. Instead, every user on the network uses the same key or passphrase to connect1.
References :=
*What is a Wi-Fi Protected Access Pre-Shared Key (WPA-PSK)?
*Exploring WPA-PSK and WiFi Security
*WPA2-Personal: This wireless security option uses a pre-shared key (PSK) for authentication. Each client that connects to the network must use this key to gain access. It is designed for home and small office networks where simplicity and ease of use are important.
*WPA2-Enterprise: Unlike WPA2-Personal, WPA2-Enterprise uses 802.1x authentication with an authentication server (such as RADIUS) and does not rely on a pre-shared key.
*802.1x: This is a network access control protocol for LANs, particularly wireless LANs. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
*802.1q: This is a networking standard that supports VLAN tagging on Ethernet networks and is not related to wireless security.

NEW QUESTION # 33
Move the security options from the list on the left to its characteristic on the right. You may use each security option once, more than once, or not at all.
Note: You will receive partial credit for each correct answer.
Answer:
Explanation:
Explanation:
The correct matching of the security options to their characteristics is as follows:
* WPA2-Enterprise: Uses a RADIUS server for authentication
* WEP: Uses a minimum of 40 bits for encryption
* WPA2-Personal: Uses AES and a pre-shared key for authentication
Here's why each security option matches the characteristic:
* WPA2-Enterpriseuses a RADIUS server for authentication, which provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.
* WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.
* WPA2-Personal(Wi-Fi Protected Access 2 - Personal) uses the Advanced Encryption Standard (AES) for encryption and a pre-shared key (PSK) for authentication, which is shared among users to access the network.
These security options are essential for protecting wireless networks from unauthorized access and ensuring data privacy.
