Which of the following is an important implementation consideration when deploying a wireless network that uses a shared password?
The correct answer is C. Key length. A wireless network using a shared password uses a Pre-Shared Key (PSK) mode, as found in WPA2-Personal. In PSK mode, the security of the entire network depends entirely on the strength of that one shared key. Key length is therefore a critical implementation consideration - a…

Explanation
A wireless network using a shared password uses a Pre-Shared Key (PSK) mode, as found in WPA2-Personal. In PSK mode, the security of the entire network depends entirely on the strength of that one shared key. Key length is therefore a critical implementation consideration - a short or weak passphrase is vulnerable to brute-force and dictionary attacks. An authentication server (A) is used in enterprise/802.1X mode, not PSK. A server certificate (B) is required in EAP-TLS or PEAP configurations, which are enterprise authentication methods. An EAP method (D) is also specific to enterprise authentication. None of these apply to a shared-password (PSK) network.
