Question

Scenario: A Citrix Administrator uses Machine Creation Services to provision Desktop OS machines in an environment. The administrator needs to update an application that is locally installed on the Desktop OS machines. Which action should the administrator take after updating the application to ensure that users are provided with the updated application?

Options

  • AUpdate the master image, then update the Delivery Group.
  • BUpdate the session machine catalog, then update the Delivery Group.
  • CUpdate the master image, then update the appropriate session machine catalog.
  • DUpdate the Desktop OS machines, then update the appropriate session machine catalog.

Why each option

In a Machine Creation Services deployment, updating a locally installed application requires updating the master image first, then updating the machine catalog to roll out the new snapshot to provisioned desktops.

AUpdate the master image, then update the Delivery Group.

Updating the Delivery Group does not control which machine image is deployed - the Delivery Group manages user assignment and policies, while the machine catalog manages the base image version.

BUpdate the session machine catalog, then update the Delivery Group.

There is no concept of a 'session machine catalog' in MCS; furthermore, updating the catalog without first updating the master image would reference the same unchanged snapshot and deliver no application changes.

CUpdate the master image, then update the appropriate session machine catalog.Correct

MCS provisions desktop machines from a snapshot of a designated master image. To deliver an application update, the administrator must install the updated application on the master VM and take a new snapshot, then update the machine catalog to reference that new snapshot. Updating the catalog triggers MCS to apply the updated image to the provisioned Desktop OS machines on next restart.

DUpdate the Desktop OS machines, then update the appropriate session machine catalog.

Updating individual provisioned Desktop OS machines directly is bypassed when MCS resets or reprovisions machines from the master image snapshot, causing changes to be lost on next reset.
