The WinSCP tool is commonly used to transfer files between Linux and Windows systems.
WinSCP has an easy GUI and encrypts the contents of the file transfer.

The cluster feature that will allow Ann to complete her task is failback. A cluster is a group of servers that work together to provide high availability, scalability, and load balancing for applications or services. A cluster can have different nodes or members that have different roles or states. An active node is a node that is currently running an application or service and serving requests from clients. A passive node is a node that is on standby and ready to take over if the active node fails. A failover is a process of switching from a failed or unavailable node to another node in a cluster. A failback is a process of switching back from a failover node to the original node after it becomes available again. Failback can be automatic or manual depending on the cluster configuration.

Explanation
This is the most likely reason why the fans in that server are operating at full speed while the ambient temperature in the room is normal and the other servers in the rack are not experiencing this behavior. A fan failure is a situation where one or more fans in a server stop working or malfunction due to wear and tear, dust, or other factors. This can cause overheating and performance issues on the server. To prevent this, most servers have a fan redundancy feature that allows the other fans to increase their speed and airflow to compensate for the failed fan and maintain a safe temperature level. The server is not likely to be in the process of shutting down, as this would not cause the fans to run at high speeds. An incorrect fan size is not likely to be inserted into the server, as most fans are standardized and compatible with the server chassis and motherboard. The server is not likely to be utilizing more memory than the other servers, as this would not cause a significant increase in temperature or fan speed. References:

Explanation: This option would reduce power consumption and maintenance costs by consolidating the physical servers into virtual machines on the hypervisors. This would also free up space and resources in the data center. The other options would either not address the request, increase power consumption, or require more maintenance.

The technician should check the hardware compatibility list (HCL) first to see if the new NIC is supported by the server's operating system. The HCL is a list of hardware devices that have been tested and verified to work with a specific operating system. If the NIC is not on the HCL, it means that there is no device driver available or compatible for it, and the NIC will not function properly.
