100-140 Question 208
Single answerYou are troubleshooting a wireless network issue for a small office. Employees report they are unable to connect to the company’s wireless network. Upon investigation, you find that the SSID for the network is not visible in the list of available networks on their devices. What is the most likely cause of this issue?
- A
The wireless access point is powered off.
- B
The SSID broadcast is disabled on the access point.
- C
The wireless devices are not compatible with the configured encryption method.
- D
The DHCP server is not assigning IP addresses to the wireless clients.
Show answer and explanation
Correct answer: B
Explanation
The SSID (Service Set Identifier) is the broadcasted name of a wireless network that allows users to identify and connect to it. If SSID broadcast is disabled on the access point, the network name will not appear in the list of available networks, requiring users to manually input the SSID and credentials. This is a common configuration option for added security but can lead to connectivity issues if users are not aware of the SSID or how to manually connect.
- A. Incorrect.
If the wireless access point is powered off, no network would be available at all, not just the SSID. This is unlikely the specific cause of the SSID not being visible.
- B. Correct.
If the SSID broadcast is disabled, the network name will not appear in the list of available networks, and users must manually configure their devices to connect to the hidden SSID.
- C. Incorrect.
While encryption incompatibility can prevent devices from connecting, it would not affect the visibility of the SSID in the available networks list.
- D. Incorrect.
A DHCP server issue would prevent devices from obtaining IP addresses but would not affect whether the SSID is visible in the network list.
