A VM with a 100 GB root disk is running a database and is currently using the 'm1.large' flavor (40 GB disk). The administrator needs to resize the VM to 'm1.xlarge' (80 GB disk) to accommodate growth. The VM is running a production workload that can tolerate a brief downtime but cannot tolerate data loss. What is the correct procedure?

Resize the VM while it is running, then confirm the resize.

Create a snapshot, delete the VM, and recreate it with 'm1.xlarge' from the snapshot.

Stop the VM, resize it to 'm1.xlarge', confirm the resize, and then start the VM.

Resize the VM to 'm1.xlarge' and then create a snapshot for backup.

A VM in OpenStack fails to boot and the administrator needs to determine why. The VM was launched with a cloud image that should support cloud-init. Which diagnostic step should the administrator take first?

Resize the VM to a larger flavor to see if it boots.

Retrieve the console log using 'openstack console log show ' and look for kernel panics or cloud-init errors.

Delete the VM and recreate it with the same parameters.

Check the VM's security group rules to ensure they allow SSH.

Which OpenStack CLI command adds a security group to an existing virtual machine instance?

openstack security group attach

openstack server security group add

openstack server update --security-group

openstack server add security group
