Complete Question:
You are running an 802.11g wireless router in mixed mode. You have three 802.11g wireless NICs using the router. A new user connects using an 802.11b wireless NIC. What will happen?
Group of answer choices.
A. The user with 802.11b will access the network at 11Mbps while the users with 802.11g will access the network at 54 Mbps.
B. The user with 802.11b will not be able to communicate on the network.
C. The user with 802.11b will access the network at 11 Mbps. The users with 802.11g will access the network at 54 Mbps unless they are communicating with the 802.11b device,which will be at 11 Mbps.
D. All users will access the network at 11 Mbps.
Answer:
D. All users will access the network at 11 Mbps.
Explanation:
A 802.11g is one of the wireless network standards developed by the Institute of Electrical and Electronics Engineers (IEEE) which operates on a 2.4 GHz microwave bandwidth and as a result can only transmit over a short distance. The 802.11g has a data transfer rate or throughput of 54 megabits per seconds (Mbps).
Basically, the 802.11b is a similar standard to the 802.11g wireless standard that typically allows the transmission (transfer) of data for up to 11 megabits per seconds (Mbps).
In this scenario, you are running an 802.11g wireless router in mixed mode. You have three 802.11g wireless NICs using the router. A new user connects using an 802.11b wireless NIC.
Hence, what will happen is that, all the users will access the network at 11 Mbps.
