An organization currently writes backups to an EMC Data Domain system and then creates encrypted copies of their backups on tapes. These tapes are then shipped to a third-party offsite vault. They are now planning to deploy a second Data Domain system to a secure data center at their corporate headquarters as a replication target to replace the use of the offsite tapes. The two sites are connected through the Internet. Where should encryption be applied on the Data Domain systems to ensure a similar level of data security as achieved by their current process?

A. Encrypt the replication context
B. Encrypt the data at rest
C. Encrypt the data at rest and the replication context
D. Encryption is not required

Answer: A

You have implemented an EMC Data Domain system with directory replication. After replication has occurred, the customer notices that the space utilization on the source and destination systems is different. How can this be explained?

A. Difference in global compression
B. Difference in the encryption algorithm
C. CIFS/NFS is mixed on the same directory
D. Destination directory may be corrupted

Answer: A

A customer is interested in deploying DD Boost for their current EMC Data Domain system. They are aware of Distributed Segment Processing (DSP) and want to know the data flow when they enable DSP. What describes the data flow from the backup host to the Data Domain system?

A. Segmenting, fingerprinting, and compression occur on the backup host. Fingerprint filtering and writes occur on the Data Domain.
B. Segmenting, fingerprinting, and fingerprint filtering occur on the backup host. Compression and writes occur on the Data Domain.
C. Fingerprinting, compression, and fingerprint filtering occur on the backup host. Segmenting and writes occur on the Data Domain.
