The question focuses oninternet-facing hosts, implying external exposure. CVSS scores, remote executability, and exploitavailability guide prioritization. Server2 (205.1.3.5, CVSS 6.5, Bind Server) has a public IP, suggesting it’s internet-facing, unlike Server1 and Server4 (192.168.x.x, private IPs). Server3 (207.1.5.7, CVSS 5.5) is also public but has a lower score and risk compared to Server2’s proof-of-concept (POC) exploit. Server2’s Bind Server (DNS) role is critical and commonly targeted, making it the priority.

Option A:Server1 (CVSS 7.5) is private, not internet-facing.

Option B:Server2 (CVSS 6.5) is internet-facing with an exploit POC, warranting immediate patching.

Option C:Server3 (CVSS 5.5) is internet-facing but less severe.

Option D:Server4 (CVSS 9.8) is critical but private, not internet-facing.
