A company uses a configuration management tool to manage its cloud VMs. An administrator needs to update the configuration of a specific application on all VMs. What is the best practice for managing this change to ensure consistency and the ability to roll back?

Manually log into each VM and apply the configuration change.

Use a script to change the configuration on each VM and store the script in a local folder on one VM.

Create a new VM with the desired configuration and migrate the application to it.

Update the configuration in the central configuration management system and let it propagate to the VMs.

What is the primary purpose of monitoring cloud resources?

To replace resources with newer versions

To automatically apply security patches

To track performance and usage for optimization

To decommission unused resources automatically

A company has a fleet of cloud VMs that are used for development and testing. An analysis of cost reports shows that many VMs are running at less than 5% CPU utilization for most of the day. The company wants to reduce costs without significantly impacting the development team's ability to work. What is the most effective optimization action?

Increase the size of the VMs to improve their performance.

Implement a policy to automatically stop VMs during non-business hours and start them again in the morning.

Migrate all VMs to a different cloud provider.

Decommission all VMs and require developers to use their local machines for testing.

A company uses a blue/green deployment strategy for its critical web application. A new version of the application has been deployed to the 'green' environment and has passed all tests. What is the next step in this lifecycle to ensure a safe and reversible rollout?

Update the load balancer to route all traffic to the 'green' environment.

Apply the same updates to the 'blue' environment to keep them in sync.

Monitor the 'green' environment for a week before making any changes to the load balancer.

Decommission the 'blue' environment immediately to save costs.

A company's cloud environment consists of several VMs running a production application. The company has set up monitoring and has noticed that one VM consistently has high network I/O but low CPU usage. What is the most appropriate optimization action based on this data?

Increase the VM's CPU allocation to improve performance.

Move the VM to a different VM size that offers a higher network bandwidth allocation.

Migrate the VM to a different availability zone to improve network performance.

Decommission the VM and recreate it with the same configuration.
