1Y0-312 Advanced Provisioning and Image Management Practice Question
An administrator has an existing Machine Creation Services catalog of non-persistent machines and needs to deploy a new version of an internally developed application to all machines with minimal disruption. The application is already installed on the master image used by the catalog. Which action should the administrator take?
⚠ Common exam trap
The trap here is thinking that a catalog must be recreated to pick up a new image, when MCS supports updating the catalog to reference a new master image snapshot.
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
✓
Update the master image with the new application version, take a new snapshot, and update the catalog to use that snapshot.
MCS catalog machines boot from clones of the master image snapshot, so the correct way to roll out an application update already present on the master image is to update that image, snapshot it, and point the catalog at the new snapshot. Machines receive the update on their next restart, avoiding catalog recreation and manual per-machine installation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Log on to each machine individually and install the new application version manually.
Why it's wrong here
Manually installing on every machine is impractical for a catalog of any size and defeats the purpose of image-based provisioning. It also risks inconsistency between machines and would not survive a reset of the OS disk on non-persistent machines, so the changes would be lost at the next restart.
- ✗
Recreate the machine catalog from scratch and re-add all machines to the delivery group.
Why it's wrong here
Recreating the catalog is unnecessarily disruptive and time-consuming when the application is already present on the master image. It would require re-provisioning all machines and reconfiguring the delivery group, causing far more downtime than necessary. Updating the master image snapshot is the appropriate minimal-disruption approach for an existing MCS catalog.
- ✓
Update the master image with the new application version, take a new snapshot, and update the catalog to use that snapshot.
Why this is correct
Because MCS clones derive from the master image snapshot, updating the master image and taking a new snapshot, then pointing the catalog at that snapshot, rolls the new application version out to all machines on their next restart. This is the standard minimal-disruption method for updating an MCS catalog and requires no catalog recreation.
- ✗
Publish the new application version as a published app from a separate delivery group.
Why it's wrong here
Publishing the application separately changes how users access it but does not update the application on the existing machines. It also introduces a second delivery group to manage and does not address the requirement to deploy the new version to the existing catalog machines with minimal disruption.
