What term describes a hardened server that provides access to other hosts in a DMZ?

• A. Air Gap
• B. VPC/VNET
• C. Jump Box
• D. Group Policies and Security Groups

Answer: (C)

A jump box is the hardened gateway that administrators use to reach other hosts in a DMZ. It sits at the perimeter and provides a controlled, auditable entry point into the DMZ, so admins first authenticate to the jump box and then access the target servers from there. This approach minimizes direct exposure of internal systems and centralizes monitoring, MFA, and access controls on a single, tightly secured host.

Other options don’t fit because they describe broader or different concepts. An air gap means total isolation with no network connection, which isn’t about providing controlled access. A VPC or VNET is a virtual network construct, not a single gateway used to hop to other hosts. Group Policies and Security Groups are access-control mechanisms and rules, not a dedicated server that mediates access to DMZ hosts.
