VEEAM VMCA2022 Practice Test 1

It has been determined that the onsite repositories need to be immutable. How should the repositories be configured to easily allow for additional capacity to be added?
Stand-alone repositories using NTFS.
Scale-out Backup Repositories consisting of hardened ReFS repositories.
Stand-alone repositories using the XFS file system.
Scale-out Backup Repositories consisting of hardened repositories.
The repositories should be configured as Scale-out Backup Repositories consisting of hardened repositories to easily allow for additional capacity to be added and to meet the immutability requirement.Scale-out Backup Repository is a logical entity that groups several backup repositories into a single pool of storage, and allows to add or remove backup repositories as needed1.Hardened repository is a Linux-based backup repository with immutability enabled, which prevents backup files from being modified or deleted until the specified retention period expires2.The other options are either not immutable (option A and C, as NTFS and XFS do not support immutability) or not scalable (option B, as ReFS does not support adding or removing extents in a Scale-out Backup Repository3).Reference:Scale-out Backup Repository,Hardened Repository,ReFS Limitations.
