CompTIA A+ 220-1102 (V14) Practice Question

When an operating system reaches End-of-Life (EOL) status, it no longer receives security updates or patches, making it vulnerable to new security threats. Upgrading to a newer, supported operating system is the best course of action to ensure continued protection against vulnerabilities. While other actions, like installing antivirus software or a firewall, provide some level of security, they cannot fully compensate for the lack of fundamental OS security updates. Enabling network segmentation can help contain threats but does not address the inherent vulnerabilities of the EOL OS itself.
