Question #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,

how many copies of the data must the TSM server database track at the primary site?

A. 1

B. 2

configuration. Based on best practices, what should be configured if the customer has less
than 6 Mb/s throughput between the installation sites?

A. Low bandwidth optimization

B. Gz compression

C. Initial replication seeding

D. Bi-directional replication

Question #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.
What is the minimum EMC Data Domain storage required?

A. 2800 GB

B. 3800 GB

C. 5600 GB

D. 7600 GB
