Which three statements are true about ASM Cloud File System (ACFS) tagging?

A.

B.
acfssettag is a command provided by a platform-dependent API to tag files.

C.
ACFS tagging is used to mark a subset of files in an ACFS file system for replication.

D.
acfsutil encr on can be used to specify the tag names of the files to be encrypted.

E.
acfsutil tag set can be used to tag files.

Explanation:

A: The acfssettag command sets the tag name on an Oracle ACFS file.
Syntax
sb8 acfssettag(const oratext *path, const oratext *tagname, oratext *value,
size_t size, ub4 flags);
C: Oracle ACFS tagging assigns a common naming attribute to a group of files. Oracle ACFS Replication can use this tag to select files with a unique tag name for
replication to a different remote cluster site. The tagging option avoids having to replicate an entire Oracle ACFS file system.
E: The acfsutil tag set command adds the given tag to the specified files or directories in an Oracle ACFS file system.
Incorrect Answers:
D: The acfsutil encr on command encrypts an Oracle ACFS file system, directories, or individual files.
However, you specify a directory not a tag name.
