This is the best action to perform before applying patches to one of the hosts in a high availability cluster. A high availability cluster is a group of hosts that act like a single system and provide continuous uptime. A high availability cluster is often used for load balancing, backup, and failover purposes. Failover is a process of transferring workloads from one host to another in case of a failure or maintenance. By failing over all VMs (Virtual Machines) from the host that needs to be patched to another host in the cluster, the technician can ensure that there is no downtime or data loss during the patching process. Disabling the heartbeat network is not a good action to perform, as this would disrupt the communication and synchronization between the hosts in the cluster. Fallback cluster services is not a valid term, but it may refer to restoring cluster services after a failover, which is not relevant before applying patches. Setting the cluster to active-active is not a good action to perform, as this would increase the load on both hosts and reduce redundancy.

Deploying a virtual machine from a template creates a virtual machine that is a copy of the template. The new virtual machine has the virtual hardware, installed software, and other properties that are configured for the template.

Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines.

Log rotation is a process that periodically renames, compresses, and deletes old log files to free up disk space and keep log files manageable. Log rotation can be configured using tools such as logrotate or cron on Linux systems, or using Windows Task Scheduler or PowerShell scripts on Windows systems. Log rotation can also help with log analysis and troubleshooting by making it easier to find relevant information in smaller and more recent log files.
