If an administrator deletes the Service 1.5 snapshot, what will be the outcome?

The correct outcome when an administrator deletes the Service 1.5 snapshot is the reversion to the Service 1 snapshot while the Service 2 snapshot remains unchanged.

In VMware, when a snapshot is deleted, the system effectively consolidates the data from the snapshot being removed back into its parent snapshot. If you delete the Service 1.5 snapshot, the virtual machine reverts to its parent snapshot, which in this case is Service 1. The state of the virtual machine will return to how it was at the point the Service 1 snapshot was taken. Meanwhile, the Service 2 snapshot is not impacted by this deletion and will stay as it was, preserving its state and data.

This behavior ensures that administrators can manage their snapshots effectively, allowing for rollbacks to various points in time while knowing that other snapshots remain intact when a specific snapshot is deleted.
