Explain ESXi and vCenter Server architectures
vCenter Server basically acts as a central control point for your ESXi hosts. Although you do have the ability to connect to each ESXi host individually, without vCenter Server you will miss out on features like vMotion, Fault Tolerance, DRS, HA, templates, vDS, etc…
Explain Private/Public/Hybrid cloud concepts
A private cloud would mean the compute and resources and ways to access all of those resource exists in the confines of your datacenter. A public cloud is the opposite of that, meaning that the compute and resources exist somewhere outside of your datacenter and are managed by a third party or service provider. Access to these resources is normally provided by means of the Internet. A hybrid simply combines both of these allowing you to run in a private and expand to the public and back and forth without service disruptions.
Determine appropriate vSphere edition based on customer requirements
Really you would need to figure out what type of workloads, how much availability you want to have as well as other factors such as DR and BC in order to determine which tier of licensing to go with. Maximums and features go up in each tier of licensing, so it's really figuring out what it is that you will need and what is available in each tier.
