In a Nutanix environment managed by Prism Central, protecting workloads and SQL servers from a disaster involves creating a recovery policy. A recovery policy in Nutanix is a set of rules that define how data is protected and recovered in the event of a disaster1.
Creating a new recovery policy involves selecting the virtual machines (VMs) that need to be protected and specifying the hardware requirements for the recovery environment1. This includes the compute and storage resources needed to run the protected VMs in the recovery site1.
Once the recovery policy is created, Nutanix's built-in data protection and disaster recovery capabilities can ensure that the protected VMs can be quickly and efficiently recovered in the event of a disaster2. This includes capabilities such as efficient snapshot, cloning, and replication capabilities to provide a higher level of protection at a lower cost2.
Therefore, to meet the CEO's request, the IT administrator should create a new Recovery policy by selecting the VM that needs to be protected and get hardware requirements.

The most straightforward approach for increasing security by disabling password authentication and moving to key-based SSH on a Nutanix cluster involves:
* C. Enable Cluster Lockdown and provide an RSA key: Cluster Lockdown mode restricts management access to the cluster, ensuring that only key-based SSH authentication is used to access the CVM and AHV hosts, enhancing security by eliminating the use of passwords.
