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 controlled gateway for administering DMZ hosts is described by the term jump box. This is a hardened server placed at the network boundary that admins connect to first, and from there access other hosts in the DMZ. The idea is to expose only this single, tightly secured entry point rather than giving direct access to every DMZ host. It simplifies security by enforcing strong authentication, auditing, and minimal services, making it easier to monitor and control who can reach the internal systems.

Air gap describes physical isolation with no network connection, which isn’t practical for administration. VPC/VNET refers to cloud networking constructs that define a network, not a dedicated admin gateway. Group Policies and Security Groups are controls that govern who and what can talk to whom, not the gateway server used to reach DMZ hosts.
