Ben disable SSID broadcast, and how could his SSID be discovered?

What network tool can be used to protect the identity of clients while
providing Internet access by accepting client requests, altering the
source addresses of the requests, mapping requests to clients, and
sending the modified requests out to their destination?

During troubleshooting, Chris uses the nslookup command to check
the IP address of a host he is attempting to connect to. The IP he sees

do to determine where her organization’s wireless network is
accessible?

The DARPA TCP/IP model’s Application layer matches up to what
three OSI model layers?

One of Susan’s attacks during a penetration test involves inserting
false ARP data into a system’s ARP cache. When the system attempts
to send traffic to the address it believes belongs to a legitimate system,
it will instead send that traffic to a system she controls. What is this
attack called?

uses MAC filtering to provide security. What is the technique Sue
used, and what nonsecurity issue could her actions cause?
