Why each option
To override DNS resolution locally and redirect specific IP addresses or URLs, editing the local hosts file is the direct and effective method.
Installing signal repeaters extends wireless network coverage but has no function in redirecting IP addresses or URLs.
The hosts file is a local text file that maps hostnames to IP addresses, and it is consulted before DNS queries are made. By editing this file, a technician can manually override DNS resolution for specific domains, directing them to different IP addresses or URLs as needed.
Configuring the firewall primarily controls network traffic ingress and egress based on rules, not for overriding DNS resolution or redirecting specific URLs.
Port forwarding directs traffic from an external port to an internal device and port, which is used for network services access, not for overriding DNS or redirecting URLs.
