You want to use RMAN to create compressed backups.
Which statement is true about the compression algorithms that RMAN can use?
A. The BZIP2 compression algorithm consumes more CPU resources than the ZLIB compression
algorithm.
B. The ZLIB compression algorithm consumes more CPU resources than the BZIP2 compression
algorithm.
C. The ZLIB compression algorithm provides maximum compression and produces smaller backups than
the BZIP2 compression algorithm.
D. Only the BZIP2 compression algorithm can be used to make compressed backups to disk.
Correct Answer: A
Section: (none)
Explanation
Explanation/Reference:
Explanation:
The BZIP2 compression algorithm consumes more CPU resources than the ZLIB compression algorithm.
The BZIP2 compression algorithm provides for optimum compression, but tends to use more CPU
resources than the ZLIB compression algorithm. The ZLIB compression algorithm is optimized for
performance and uses less CPU resources. You should note that the COMPATIBLE initialization
parameter must be set to 11.0.0 or higher to use the ZLIB compression algorithm.
The option that states the ZLIB compression algorithm consumes more CPU resources than the BZIP2
compression algorithm is incorrect. The BZIP2 compression algorithm consumes more CPU resources.
The option that states the ZLIB compression algorithm provides maximum compression and produces
smaller backups than the BZIP2 compression algorithm is incorrect. The BZIP2 compression algorithm
provides maximum compression and produces smaller backups than the ZLIB compression algorithm.
The option that states only the BZIP2 compression algorithm can be used to make compressed backups to
disk is incorrect. The ZLIB compression algorithm can also be used to make compressed backups to disk.
