A company uses its own private cloud, which has few available resources. Mission-critical systems and other information systems are running on it. A new system will be deployed on the private cloud…

Scheduling from 02:00-04:00 is a deep overnight period; while it is off-peak, other maintenance or backup windows might be scheduled, and it's not always the *most* suitable if early morning business processes start soon after.

Scheduling from 09:00-12:00 falls within typical peak business hours, which would cause maximum contention for resources and significant disruption to mission-critical systems and active users.

Scheduling the 2-hour load test from 18:00-20:00 aligns with a typical business evening period when mission-critical systems are likely experiencing reduced operational load compared to peak business hours, thus minimizing resource contention and impact on existing production workloads. This allows the load test to run without significantly degrading performance for active users or critical business processes.

Scheduling from 22:00-00:00 is late at night and could overlap with critical overnight batch jobs, backups, or system maintenance windows that are specifically designed for low-impact times.
