What factor should have been considered to prevent connectivity loss to a server installed in a writing closet?

The correct choice is related to how airflow influences server performance and connectivity. In a writing closet, where servers may be placed in a confined space, improper airflow can lead to overheating. Servers generate heat during operation, and if they are not provided with sufficient airflow, this heat can accumulate and cause the server to throttle performance or shut down.

Maintaining adequate airflow ensures that components receive proper cooling, which helps prevent failures that could lead to connectivity loss. This is significant because, without proper temperature management, the server could become unresponsive or crash, disrupting connectivity to it.

Redundant power is also crucial but focuses more on preventing downtime due to power failure rather than directly addressing issues tied to overheating. Antivirus software is essential for security, while chassis lock pertains to physical security, neither of which contribute to ensuring connectivity in an environment where airflow is a concern. Proper airflow management is key to sustaining optimal server operation, thereby enhancing connectivity.
