1. Which segment size(s) is used by EMC Data Domain SISL?

2. What does the EMC Data Domain file level retention locking feature provide?

3. Which method of deduplication yields better deduplication results for multiple data types?

4. You have deployed an EMC Data Domain system in a customer environment. Recently, the customer expressed concerns regarding data integrity issues.

Which Data Domain system attributes protect against stored data corruption?

5. Where does in-line deduplication occur in an EMC Data Domain (DD) system?

6. A customer is deploying EMC Data Domain systems in four data centers worldwide. The Data Domain systems will be using VTL. Each system will have a unique tape pool.

The customer wants to replicate data to all sites. The data needs to be encrypted locally and then replicated to remote sites over the WAN.

What needs to be deployed to meet the customer's requirements?

7. When a customer deploys an EMC Data Domain system at a remote location that does not have an IT staff, what type of remote management method(s) is possible?

8. An organization currently writes backups to an EMC Data Domain system and then creates encrypted copies of their backups on tapes. These tapes are then shipped to a third-party offsite vault.

They are now planning to deploy a second Data Domain system in a hosted disaster recovery site as a replication target. This will replace the use of the offsite tapes. The two sites are connected through an encrypted WAN link.

Where should encryption be applied on the Data Domain systems to ensure a similar level of data security as their current process?

9. What is a characteristic of EMC Data Domain collection replication?

10. An EMC Data Domain customer wants VTL replication functionality.

Which licensing option is required?

11. Which hardware and capacity license options are available for an EMC Data Domain system?

12. Data exposure must be minimized when disk-based hardware is shipped.

Which Data Domain software licenses need to be applied to the system?

13. Which two licenses are tied to capacity on an EMC Data Domain system?

14. What is the name of the dedicated IPMI management Ethernet port on an EMC Data Domain system?

15. You are installing an EMC Data Domain system with two expansion shelves in a customer-provided rack.

When cabling the controller to the shelves, where does the host port on the last shelf in the chain get connected?

16. What is indicated by a flashing green LED on an EMC Data Domain Expansion Shelf SAS Controller?

17. Refer to the Exhibit.

When connecting a single expansion shelf to a EMC Data Doman controller, what are the recommended SAS ports that should be used?

18. Refer to the Exhibit.

When creating a second shelf chain on a EMC Data Doman controller, what are the two recommended SAS ports that should be used?

When cabling the controller to the shelves, where does the expansion port on the last shelf get connected?

20. If you have a 2U EMC Data Domain Controller with three expansion shelves, what is the total rack space needed?

21. In an EMC Data Domain environment, when are cage nuts used?

22. A customer's EMC Data Domain system has an Ethernet port called "bmc0a".

What is the purpose of this Ethernet port?

23. What are the states of the SAS LED connection status indicators at the back of an EMC Data Domain ES20?

24. What is the current NAA type in the WWN format used within EMC Data Domain OS 5.4?

25. What changed in the WWN format of the EMC Data Domain OS 5.4?

26. What can an optional PCI-x Card slot be used for on an EMC Data Domain system?

27. Which command is used to check the SAS HBA card status on an EMC Data Domain system?

28. What is the default password on a new EMC Data Domain system?

29. A customer environment has an EMC Data Domain system with Data Domain Extended Retention enabled. The environment has three sealed extended retention units. The customer notices a slight delay when accessing the oldest data sets.

What is a potential reason for this issue?

30. A customer is using EMC NetWorker with EMC DD Boost, writing to a Data Domain DD990. Due to regulatory requirements, the customer must keep their data for seven years.
