Question No : 6
A customer has an IBM Tivoli Storage Manager (TSM) environment with multiple EMC
Data Domain systems. Backups are stored on Data Domain system A and replicated to
Data Domain system B. The Tape Library contains a copy pool.
Based on the exhibit,

B. Gz compression
C. Initial replication seeding
D. Bi-directional replication
Question No : 8
An organization has 3000 GB of file system data with a daily change rate of 10%. Assume
the first backup reduces by a factor of 3 (3x), daily incremental backups reduce by a factor
of 10 (10x), and subsequent full backups reduce by a factor of 30 (30x). Required retention
is 10 weeks (1 weekly full/6 daily incrementals) and system utilization cannot exceed 50%
of available capacity.
