1Y0-204 App and Desktop Image Management Practice Question
An administrator is preparing a master image for a new Citrix Virtual Apps and Desktops 7 deployment using Machine Creation Services (MCS). After installing the Virtual Delivery Agent (VDA) and all required applications, the administrator shuts down the master VM and takes a snapshot. However, when creating the machine catalog, the snapshot does not appear in the list of available images. What is the most likely cause of this issue?
⚠ Common exam trap
The trap here is assuming that any snapshot from any VM will be available, ignoring the requirement that the VM must belong to the selected hosting connection.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The snapshot was taken on a VM that is not part of the hosting connection used for the catalog.
For MCS to use a snapshot as the master image, the snapshot must be taken from a VM that is part of the hosting connection configured in Citrix Studio. If the master VM is on a different host or cluster not included in that connection, its snapshots will not appear. Ensuring the master VM resides within the correct hosting connection resolves the issue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The snapshot name must follow a specific naming convention.
Why it's wrong here
Citrix MCS does not require a specific naming convention for snapshots. Any snapshot name is acceptable as long as it is taken from a VM within the hosting connection. The catalog creation wizard displays all available snapshots regardless of their names. Therefore, a naming convention is not the reason the snapshot is missing. The issue is more likely related to the hosting connection or VM location.
- ✗
The master VM must be a template, not a snapshot.
Why it's wrong here
MCS can use either a snapshot or a template as the master image source, depending on the hypervisor. For example, with VMware, snapshots are commonly used; with XenServer, both templates and snapshots are supported. Requiring a template is not accurate for all hypervisors. The absence of the snapshot in the list is not because a template is mandatory, but likely because the VM is not in the correct hosting connection.
- ✓
The snapshot was taken on a VM that is not part of the hosting connection used for the catalog.
Why this is correct
MCS only lists snapshots from VMs that belong to the hosting connection selected during catalog creation. If the master VM resides on a different hypervisor host, cluster, or resource pool that is not part of the configured hosting connection, its snapshot will not be visible. The administrator must ensure the master VM is in the same hosting connection or add the appropriate host. This is the most likely cause given the scenario.
- ✗
The master VM must be running when the snapshot is taken.
Why it's wrong here
MCS requires the master VM to be powered off before taking a snapshot to ensure a consistent state. A running VM snapshot may not be offered for catalog creation because it can capture in-progress writes and lead to unstable clones. However, the primary reason a snapshot does not appear is not that the VM was running; rather, it is usually due to the snapshot not being taken on the correct VM or the hosting connection not being configured properly. In this scenario, the VM was shut down, so this is not the cause.
