Question #1. What are some of the virtualization-related services available to System Administrators to ensure high availability for important servers? Name and explain some of these features available in either Hyper-V or VMware and describe the benefits.

For example: Live Migration or vMotion, HA or Failover Cluster, DSR (Distributed Resource Scheduler), FT (fault tolerance), etc.

Question #2. Provide a real-world example of how some of these HA features are being used by real companies. I suggest searching for case studies or use cases of the tools that you choose to describe.

It is NOT enough to give a generic one-sentence definition of what is HA. You should do more research (and post more details) if you wish to learn about these very important features of virtualization.
