The correct answers are B. Disk space and D. Database size growth. CompTIA DataSys+ places strong emphasis on storage monitoring as a critical responsibility of a database administrator (DBA), particularly to ensure ongoing performance, availability, and capacity planning. Physical storage constraints directly affect database operations such as inserts, updates, indexing, backups, and transaction logging.
Disk space monitoring is essential because databases require sufficient free storage not only for data files, but also for transaction logs, temporary files, indexes, and maintenance operations. If disk space becomes constrained, the database may experience degraded performance, failed write operations, or complete service outages. DataSys+ highlights proactive disk monitoring as a best practice to prevent unplanned downtime and emergency remediation.
Database size growth is equally important because it enables the DBA to anticipate future storage needs. Databases rarely remain static; they grow as new records are added, indexes expand, and historical data accumulates. By tracking growth trends, administrators can forecast when additional storage will be required and take action before performance is impacted. DataSys+ identifies capacity planning as a key operational task, and monitoring growth patterns is central to that process.
Option A, network traffic, affects connectivity and throughput but does not determine physical storage availability. Option C, concurrent connections, relates to workload and performance but not disk capacity. Option E, CPU usage, and option F, RAM usage, are critical server health metrics, but they do not indicate whether sufficient physical storage exists.
CompTIA DataSys+ clearly distinguishes between compute resources and storage resources. To ensure adequate physical storage and sustained performance, DBAs must monitor both current disk utilization and long-term database growth. Therefore, B and D are the correct and fully verified answers.
