Detailed explanation-1: -Expert Answer. The ideal way to give access to confidential resources over the internet is by using a virtual private network because encrypting all data ensures a safe connection between the client and server.
Detailed explanation-2: -Router. A router directs data requests from one network to another. Routers examine incoming packets to determine the appropriate destination IP address and then forward the packet to that destination. A router can also enable internet access through its connection to a modem, or as a combined modem-router.
Detailed explanation-3: -Where should an organization’s web server be placed? EXPLANATION A web server should be placed in the demilitarized zone (DMZ). The DMZ is a network that contains publicly accessible resources. The DMZ is located between the private network and an untrusted network (such as the internet) and is protected by a ûrewall.
Detailed explanation-4: -What needs to be configured on a firewall to allow traffic directed to the public resource in the DMZ? EXPLANATION Packet filters on the firewall allow traffic directed to the public resources inside the DMZ. Packet filters also prevent unauthorized traffic from reaching the private network.
