Employees are unable to browse the internet by url but are able browse to websites by entering exact ip addresses. This happened after a new firewall was installed. What should the administrator do to fix the problem?
Configure the firewall to allow traffic on TCP port 53 and UDP port 53
Configure the firewall to allow traffic on TCP port 80 and UDP port 443
Configure the firewall to allow traffic on TCP port 8080
Configure the firewall to allow traffic on port TCP 53 only
Although port 80, 8080, and 443 are essential to internet browsing, name resolution, typing in a URL instead of a web server IP address, is a function of DNS, the domain name service. DNS works on TCP/UDP 53, which is why this is the best option compared to just TCP port 53.
