FREE E20-385 Data Domain Specialist Implementation Engineers Questions

1. In which path location are Autosupport logs stored on an EMC Data Domain system?

2. You are responsible for capacity planning in an EMC Data Domain environment. While monitoring space usage over a series of weeks, you notice a sudden increase in space consumption. The new rate of consumption will require additional capacity.
What is the most likely cause?

3. A customer's EMC Data Domain system reports a global compression ratio of 7.8x. This does not meet the customer’s expectations.
What can be done to increase the data reduction ratio?

4. An EMC Data Domain system has been installed at a customer's site for several months and has reached steady state. At which threshold percent does capacity reach the point where action should be taken to make more free space available?

5. When monitoring EMC Data Domain systems, an administrator sees the System Manager File System Summary showing a compression factor of 20x. How is the equivalent value shown in the "Reduction%" column?

6. What is a benefit of snapshots on an EMC Data Domain system?

7. On an EMC Data Domain system, what is the role of file system cleaning?

8. A company is replicating two specific directories between two EMC Data Domain systems using a 4 Mb/s WAN connection. What can be done on the Data Domain systems to maximize replication performance?

9. When logging into an EMC Data Domain system during an initial installation, which connection type must be used?

10. After backups are expired and data is marked for deletion, when is space freed up on an EMC Data Domain file system?

11. Refer to Exhibit.


An EMC Data Domain customer has three offices with their payroll backups currently located in San Jose, California. They want to plan a disaster recovery strategy. The customer is concerned with the possibility of multiple disasters that could compromise both the source and destination sites simultaneously.
Which replication topology will address the customer's concerns about availability and RTO?
