Which setting should be checked to diagnose why a hyperlink redirects to a malicious site?

• A. Proxy Server Configuration
• B. Firewall Rules
• C. DNS Cache
• D. Browser Extensions

Answer: (A)

When a hyperlink sends you to a malicious site, examine how your traffic is being routed rather than just what you clicked. A proxy server between your device and the Internet can modify requests or responses, effectively redirecting you to a harmful site even if the link itself looks legitimate. Checking the Proxy Server Configuration—both on the device and in the browser, and any automatic configuration scripts (PAC files)—helps you determine if traffic is being forced through a proxy that rewrites destinations. To test, try bypassing the proxy and loading the link directly; if the redirect disappears, the proxy setup is the likely cause. Other possibilities exist, such as DNS cache issues or browser extensions that hijack links, which is why those should be reviewed if the proxy check doesn’t explain the behavior. Firewall rules, meanwhile, tend to block or allow traffic rather than redirecting you to a different site.
