An enterprise has deployed multiple applications, such as desktop cloud, database, video on demand (VoD), and backup. These applications occupy a large amount of storage resources. The enterprise plans to use the deduplication and compression features. Which of the following configurations are recommended?

A. Deduplication and compression are not recommended for VOD scenarios because video files have been compressed by application software and re-compression will be inefficient.

B. Deduplication is recommended for desktop cloud scenarios because there is a large amount of duplicate data among multiple virtual images.

C. Compression is recommended for database-scenarios because a large amount of data needs to be stored.

D. Deduplication is not recommended for backup scenarios because all backup data must be retained.
