A cloud infrastructure function that can grow and shrink to meet peak demand requirements quickly is known as:

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. The following tests are included in the test plan:
* Load test (2h)
* Backup/restore test (6h)
* Functional test (8h)
* Failover test (1h)
The work schedule of the existing system is shown below.

To minimize the effect to the existing system, which of the following schedules is MOST suitable for the load test?
