Dylan is the systems administrator for Intern Support Staffing, an IT staffing company in Oregon. All workstations on the company�s network are running Windows XP SP2 except for three laptops that run MAC OS X. Even though Dylan has setup and configured a hardware firewall for the company, a recent audit suggested he utilize application-level firewalls for all workstations and mobile computers. Dylan configures the Windows Firewall settings for the Windows computers.Dylan then downloads and installs Doorstop X Firewall onto the MAC laptops. After installation, none of the MAC laptops can connect to any other computers on the network. Why are these laptops not able to connect to other computers afterDylan installed Doorstop X Firewall?

A.
The laptops cannot connect because all TCP ports are protected by default when Doorstop X Firewall is installed.

B.
They cannot make a connection because he needs to modify the firewall.conf file before they can use the software properly.

C.
Dylan needs to modify the local firewall.data files on all the MAC laptops before they can function properly.

D.
They cannot connect to other computers on the network because Dylan needs to install the �Network Services for MAC� piece on all the Windows workstations.
