A company prevented direct access from the database administrators’ workstations to the network segment that contains database servers. Which of the following should a database administrator use to access the database servers?

A jump server (also known as a jump host or bastion host) is a hardened, intermediary server used to access more sensitive systems on a different network segment. By preventing direct access from workstations to database servers, the company implements a security control. Database administrators would connect to the jump server first, and then from the jump server, connect to the database servers. This creates an auditable and controlled pathway, reducing the attack surface. RADIUS (Remote Authentication Dial-In User Service) is an authentication, authorization, and accounting (AAA) protocol, not a server for accessing resources. An HSM (Hardware Security Module) is a physical computing device that safeguards and manages digital keys, used for cryptographic operations, not for network access. A load balancer distributes network traffic across multiple servers to improve performance and reliability, but it doesn't provide a secure access method for administrators.
