After a datacenter blackout, which policy should be reviewed to ensure VMs start up in the correct sequence?

1. Monitoring policy

2. Change management policy

3. Service level agreement policy

4. Boot sequence policy

The correct answer is: Change management policy

To ensure that virtual machines (VMs) start up in the correct sequence after a datacenter blackout, the appropriate policy to review is the boot sequence policy. This policy outlines the order in which the VMs are to be powered on following an outage. Starting VMs in the proper sequence is crucial because some applications and services depend on others being available first. For instance, a database server should be running before any applications that require access to it. The boot sequence policy directly addresses this need, helping administrators prioritize essential services and minimize downtime. The other policies mentioned—monitoring, change management, and service level agreements—while important to the overall operation and governance of IT services, do not specifically address the order in which VMs should boot up after a lack of power. Monitoring policies focus on the surveillance of system health, change management policies govern how changes are made to systems, and service level agreements define the expectations of service availability and performance, but none provide the sequencing necessary to ensure a proper startup sequence post-blackout.
