R2...................
The login command is missing from the console mode on R2.

same subnetwork.
There must be a terminal emulator application on the
computer................................
45.
46. What is the outcome when a wireless host has a different SSID
configured than the access point to which it is attempting to connect?
The access point will send the host a rejection message.
The host will be prompted for a userid and password.
The access point will send the host a challenge message.
The host will only be allowed access to the Internet.
The access point will send the host a re-authentication request
message.
The host will not be allowed access to the wireless
network.............................
47. A wireless network has one access point installed. Users at some
locations in the office complain that their wireless access is slow,
while others say that the wireless network performance is fine. What
should be done to remedy this situation?
