Which of the following server types requires the LARGEST amount of available hard drive space?

Database servers are responsible for persisting large datasets including tables, indexes, transaction logs, and backups, all of which accumulate significant storage over time. Unlike other server roles that process or route data transiently, a database server is the authoritative storage location for organizational data. This makes raw storage capacity a primary hardware requirement for database servers.

Remote access servers manage authentication sessions and connection brokering and do not persistently store large user data payloads, requiring minimal local disk space.

Print servers spool print jobs temporarily and store printer drivers and configurations, which represent a very small and bounded storage footprint.

Directory servers such as those running LDAP or Active Directory store user accounts, group policies, and object attributes, which are relatively small structured datasets compared to full application databases.
