GPEN · Question #287
Which of the following statements are true about SSIDs? Each correct answer represents a complete solution. Choose all that apply.
The correct answer is B. Configuring the same SSID as that of the other Wireless Access Points (WAPs) of other C. SSID is used to identify a wireless network. D. All wireless devices on a wireless network must have the same SSID in order to communicate. SSIDs are case-sensitive identifiers with a 32-character maximum length, and all devices on the same wireless network must share the same SSID to associate and communicate.

Why each option
SSIDs are case-sensitive identifiers with a 32-character maximum length, and all devices on the same wireless network must share the same SSID to associate and communicate.
SSIDs are case-sensitive strings, so 'Corp' and 'corp' are treated as distinct networks, and the maximum allowable length defined by the IEEE 802.11 standard is 32 characters, not 64.
Configuring the same SSID as a neighboring organization's WAP causes client devices to potentially associate with the wrong access point, which can be exploited in evil twin or rogue AP attacks where an attacker mimics a legitimate SSID to intercept traffic.
The SSID (Service Set Identifier) is the primary human-readable name broadcast in 802.11 beacon frames that allows clients to discover and identify available wireless networks.
The IEEE 802.11 standard requires all devices wishing to join a particular BSS (Basic Service Set) to be configured with the matching SSID; a mismatch prevents association entirely.
