You have a server named Server1 that runs Windows Server 2012 R2. The storage on Server1 is configured as shown in the following table.

You plan to implement Data Deduplication on Server1. You need to identify on which drives you can enable Data Deduplication. Which three drives should you
identify? (Each correct answer presents part of the solution. Choose three.)

A.

Explanation:
Volumes that are candidates for deduplication must conform to the following requirements:
* (not A) Must not be a system or boot volume. Deduplication is not supported on operating system volumes.
* Can be partitioned as a master boot record (MBR) or a GUID Partition Table (GPT), and must be formatted using the NTFS file system.
* Can reside on shared storage, such as storage that uses a Fibre Channel or an SAS array, or when an iSCSI SAN and Windows Failover Clustering is fully
supported.
* Do not rely on Cluster Shared Volumes (CSVs). You can access data if a deduplicationenabled volume is converted to a CSV, but you cannot continue to process
files for deduplication.
* (not C) Do not rely on the Microsoft Resilient File System (ReFS).
* Must be exposed to the operating system as non-removable drives. Remotely-mapped drives are not supported.
