After the implementation of SSL (Secure Sockets Layer) redirection, the inability of users to access certain web-based applications or content, like a random number generator, suggests a compatibility or compliance issue with HTTPS (HyperText Transfer Protocol Secure). The first troubleshooting step should be to verify if the website in question supports HTTPS, as SSL redirection forces connections to use HTTPS for security. If the website only operates over HTTP, it won't be accessible after SSL redirection is implemented, leading to the issues reported by users.

If an application was previously running in a virtualized environment and is not launching after being installed directly on the base operating system, it's possible that the technician did not account for dependencies or configurations specific to the virtualized environment that are not present or are incompatible with the base operating system. This mismatch can prevent the application from launching properly.

Since the user can ping 8.8.4.4 (an external IP address) but is unable to browse web pages, it indicates that the DNS (Domain Name System) settings may be incorrect or not configured. The DNS system is crucial for translating human-friendly domain names into IP addresses. If DNS settings are incorrect, the browser cannot resolve domain names, thus web pages will not load despite the network itself being reachable via IP. The other options are less likely as they would affect connectivity to external IP addresses or the availability of specific websites.

A digitizer is a component that handles touch-screen operation on a mobile device. It is a layer of material that detects and converts the touch of a finger or a stylus into an electrical signal that can be processed by the device12. A digitizer works with a display screen to create a touch-screen interface that allows a user to interact with the device by touching pictures or words on the screen.
