Question

A new WAP is configured to only use 802.11g with SSID broadcasts enabled. The encryption is set to WPA and the key is given to the user. A user near the WAP is using a laptop equipped with a 5GHz wireless card and is not able to see the SSID. Which of the following is the problem?

Options

ALatency
BIncorrect encryption type
CEUI-64
DIncompatible hardware

Explanation

802.11g operates exclusively on the 2.4GHz frequency band. The user's laptop is equipped with a 5GHz-only wireless card, which is physically incapable of detecting or communicating with a 2.4GHz network. Since the hardware frequencies do not overlap, the SSID will be completely invisible to that card. Encryption type (B) is irrelevant because the card cannot even see the network. Latency (A) and EUI-64 (C) - an IPv6 interface identifier mechanism - have no bearing on whether an SSID is visible.
