What role does a bastion host serve in a subnet configuration?

• A. To act as a backup storage solution
• B. To provide external access to subnet resources
• C. To serve as a primary server
• D. To manage data encryption

Answer: (B)

A bastion host plays a crucial role in network security by acting as a gateway for external access to resources within a private subnet. This host is specifically configured to withstand attacks, making it a secure point through which external users can access the internal network. It typically has stringent security measures and is often placed in the demilitarized zone (DMZ) of a network architecture. In practical terms, the bastion host enables users from outside the network to connect safely to resources that are not directly exposed to the internet. This might include access to servers, applications, or databases housed in the subnet. By funneling traffic through this one host, organizations can better audit and control access to their critical resources, enhancing overall security. The other choices do not accurately describe the functionality of a bastion host. For instance, a backup storage solution does not relate to external access, nor do primary server roles or data encryption management directly pertain to the bastion host's purpose within a subnet.
