Your team manages a web application running on Compute Engine VMs in a managed instance group. You need to apply a critical security patch to the operating system. The patch requires a reboot. You want to minimize downtime and ensure that the application remains available throughout the process. What should you do?

Use a canary deployment to apply the patch to one instance at a time

Perform a rolling update with a max surge of 1 and max unavailable of 0

Apply the patch manually to each instance without using a rolling update

Stop all instances, apply the patch, and restart them

How can reservations help optimize costs?

By eliminating the need for monitoring

By automatically stopping unused resources

By providing discounted pricing in exchange for a commitment to use resources

By reducing the number of required instances
