The correct answer is B. As a VM hosted app on Windows 7 x86 deployed with Provisioning Services. Deploying a proprietary 16-bit application as an On-Demand App necessitates a 32-bit client operating system for optimal compatibility, combined with a provisioning solution that supports single-image management and swift rollback.

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. How should the architect deploy MGMT as an On-Demand App?

Options

  • AAs a VM hosted app on Windows 7 x86 deployed with Machine Creation Services
  • BAs a VM hosted app on Windows 7 x86 deployed with Provisioning Services
  • CAs a published application on Windows Server 2008 R2 deployed with Machine Creation Services
  • DAs a published application on Windows Server 2012 R2 deployed with Provisioning Services

Why each option

Deploying a proprietary 16-bit application as an On-Demand App necessitates a 32-bit client operating system for optimal compatibility, combined with a provisioning solution that supports single-image management and swift rollback.

AAs a VM hosted app on Windows 7 x86 deployed with Machine Creation Services

Machine Creation Services (MCS) does not provide the same granular and instant rollback capabilities via vDisk versioning as Provisioning Services (PVS), which is a key requirement for managing instability.

BAs a VM hosted app on Windows 7 x86 deployed with Provisioning ServicesCorrect

A VM hosted app on Windows 7 x86 (32-bit) provides superior compatibility for legacy 16-bit applications due to its native support for the NTVDM subsystem, which is crucial for the proprietary MGMT application. Provisioning Services (PVS) ensures efficient single-image management, simplified updates, and a fast rollback mechanism through vDisk versioning, meeting the requirements for minimal management and rapid recovery from potential instability.

CAs a published application on Windows Server 2008 R2 deployed with Machine Creation Services

Windows Server 2008 R2 (likely 64-bit) may present compatibility challenges for a 16-bit application compared to a 32-bit client OS like Windows 7 x86, and MCS lacks the desired rollback features of PVS.

DAs a published application on Windows Server 2012 R2 deployed with Provisioning Services

Windows Server 2012 R2 (likely 64-bit) has reduced native support for 16-bit applications compared to a 32-bit client OS, making it less suitable for critical compatibility, despite PVS offering good image management.
