Which Veeam Backup & Replication component or service should be added to the scenario below in order to optimize backups to an off-site CIFS share?
A. In additional backup repository in the remote site
B. A WAN Accelerator service in the remote location
C. An additional Data Mover service on the Veeam Backup & Replication server
D. A Windows-based gateway server in the remote site
I think the answer is D

The answer is D (Page 35 of the VMCE Notes)
CIFS (SMB) share. This type of repository does not support Veeam data mover services, therefore data to the SMB share is written from a Windows-based gateway server. By default, this role is performed by the Backup Proxy that is utilized by the job for data transport.
However, if you plan to move VM data to an offsite SMB repository over a WAN link, it is recommended that you deploy an additional Windows gateway server in the remote site, closer to the SMB repository.
Veeam Backup & Replication will deploy a Veeam data mover service on that proxy server, which will improve data transfer performance.
I think the correct answer is C
C. An additional Data Mover service on the Veeam Backup & Replication server
CIFS needs a backup proxy in the remote site
Veeam starts the target-side Veeam data mover service on the proxying server
