Scenario: CGE acquires a small energy company that is running MGMT, a proprietary 16-bit application. A Citrix Architect is tasked with deploying this application to the Executives/Management end-user

The correct answer is D. It enables faster rollbacks.. The scenario requires deploying a 16-bit application using a single-image FlexCast model with minimal management and a fast rollback plan. The chosen Hosted Shared environment with Provisioning Services is best because it provides efficient rollback capabilities.

Question

Scenario: CGE acquires a small energy company that is running MGMT, a proprietary 16-bit application. A Citrix Architect is tasked with deploying this application to the Executives/Management end-user group. The CIO mandates that a FlexCast model must be chosen that resembles this end-user group's existing delivery strategy. It is important that a single-image deployment is utilized and that management effort is kept to a minimum for the update process. The availability of a fast rollback plan must also be available after upgrades, since it can often result in system instability. Why is deploying MGMT in a Hosted Shared environment on Windows Server 2008 R2 with Provisioning Services the best solution?

Options

  • AIt offers a faster change process.
  • BEnd users are already comfortable working in a shared environment.
  • CIt prevents XenApp server crashes.
  • DIt enables faster rollbacks.

Why each option

The scenario requires deploying a 16-bit application using a single-image FlexCast model with minimal management and a fast rollback plan. The chosen Hosted Shared environment with Provisioning Services is best because it provides efficient rollback capabilities.

AIt offers a faster change process.

While PVS streamlines the change process through single image management, the primary and most direct benefit for the specific scenario requirement of 'fast rollback' is the vDisk versioning.

BEnd users are already comfortable working in a shared environment.

The scenario mentions resembling an existing strategy but does not explicitly state end-user comfort with shared environments as the technical reason for PVS or the solution's best fit.

CIt prevents XenApp server crashes.

PVS helps with recovery and consistent image deployment but does not prevent server crashes; it facilitates rapid restoration from failures.

DIt enables faster rollbacks.Correct

Citrix Provisioning Services (PVS) uses vDisk versioning, allowing administrators to create and revert to previous versions of a virtual disk image instantly. This feature directly addresses the requirement for a fast rollback plan after upgrades, which is crucial for maintaining system stability and business continuity when deploying potentially unstable applications.
