What is a hardened server that provides access to other hosts called?

• A. Proxy server
• B. Jump server
• C. Load balancer
• D. DNS server

Answer: (B)

Centralized, controlled access into a private network through a hardened gateway is the idea. A jump server, also called a bastion host, is a hardened machine specifically built to provide access to other internal hosts. Administrators connect to this single secure point, then reach the internal systems from there. This reduces the attack surface by avoiding direct exposure of many machines, and it enables stronger authentication, detailed auditing, and centralized monitoring of management sessions. Proxy servers forward requests but aren’t designed as a secure gateway into a private network; load balancers distribute traffic across multiple servers rather than provide trusted access to internal hosts; DNS servers resolve names but don’t grant access to the internal machines.
