What is the maximum distance with maximum data rate for 802.11g?
Answer: B
Correct answer: About 90-100 feet
802.11g reaches about 90 to 100 feet at 54 Mbps. It sits between the other two: better than 802.11a’s 65 to 75 feet because 2.4 GHz propagates further, but well short of 802.11b’s 150 feet because holding 54 Mbps demands a much stronger signal than holding 11.

What is the maximum distance running the lowest data rate for 802.11g?
Answer: C
Correct answer: About 300 feet
At its lowest rate 802.11g reaches about 300 feet, a little short of 802.11b’s 350. The two share a band, so the difference lies in the modulation each falls back to rather than in propagation, and the ordering of the three standards is the same at every rate: b furthest, g next, a shortest.

You are connecting your access point and it is set to root. What does Extended Service Set ID mean?
Answer: A
Correct answer: That you have more than one access point and they are in the same SSID connected by a distribution system.
An Extended Service Set joins two or more basic service sets under one SSID, linked by a distribution system - usually the wired network. Because the SSID is shared, a client can roam between the access points without reassociating to a different network. Separate SSIDs would be separate networks, and the physical placement of the access points is not what defines the term.

What is the maximum data rate for the 802.11g standard?
Answer: D
Correct answer: 54Mbps
802.11g reaches 54 Mbps, matching 802.11a while staying in the 2.4 GHz band, which is what made it backward compatible with 802.11b equipment. That compatibility has a cost: when a b client associates, the cell falls back to protection mechanisms that reduce throughput for everyone on it.

What is the frequency range of the IEEE 802.11g standard?
Answer: C
Correct answer: 2.4GHz
802.11g operates at 2.4 GHz, the same band as 802.11b, which is precisely what allows the two to interoperate in one cell. It therefore inherits the band’s limitations as well - three non-overlapping channels and interference from every other device in the ISM band. Two of the options here are again rates rather than frequencies.
