Correct answer: broadcasts beacon frames by default to announce the network.
Why this is the answer
An SSID (Service Set Identifier) is the name of a wireless network. By default, wireless access points (APs) broadcast beacon frames that contain the SSID, allowing wireless clients to discover and connect to the network. This "announcement" makes the network visible to devices within range. While an SSID can be configured to not broadcast (often called "hidden SSID"), the default behavior is to broadcast. Incorrect options: Preventing client piggybacking is typically handled by security measures like WPA2/WPA3 encryption and strong passwords, not the SSID itself. An SSID is a network name, not a user login ID. User authentication (if required) happens after selecting the SSID. An SSID can consist of only letters, only numbers, or a combination of both, and even special characters. There's no strict requirement for both letters and numbers.
