Which solution meets the criteria for reducing the general IT costs for the Research and Training user group to access their applications?

Scenario:

CGE needs to define its management process for desktop image releases. Some groups need a process for version control that includes thorough testing prior to production.

Which tool should a Citrix Architect recommend for those groups?

Scenario:

CGE has a new XenApp image for hosting office applications and will use Provisioning Services to deploy the servers hosting these applications. However, CGE is concerned that their current strategy for deploying antivirus definition updates will reduce the performance of the provisioned servers.

Additionally, the Security team is concerned about the frequency of the antivirus definition updates and would like to have as many updates as possible without reducing performance of the provisioned disk.

Which change should a Citrix Architect recommend to CGE's current strategy for deploying antivirus definitions?
