On an EMC Data Domain system, what is the role of file system cleaning?
Where is the file system metadata stored on a Dell EMC Data Domain system with Extended Retention software?
Which SAS ports on Link Controller Cards (LCCs) are supported by Dell EMC Data Domain systems for a DS60 Shelf?
What does the EMC Data Domain file level retention locking feature provide?
When using VTL on an EMC Data Domain system, why should persistent binding be enabled on the host?
What is the maximum value of 'Mount Limit' for restore instances recommended by IBM Spectrum Protect for accessing an NFS share from Dell EMC Data Domain?
The default Mount Limit value is 20 and the maximum value for this parameter is 4096. This means that up to 4096 individual files can be opened at a single time.

Which segment size(s) is used by EMC Data Domain SISL?
An EMC Data Domain customer wants to set up link aggregation using two network interface connections. The connections will go from the Data Domain system to Switch A and Switch B. The following IP/networking configuration will be used to create the aggregation:
Switch A is connected to DD interface eth3a
10 GB link
IP = 10.200.1.10
Switch B is connected to DD interface eth4b
1 GB link
IP = 10.200.1.11
Which mode would you recommend for this configuration?
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?
An EMC Data Domain administrator needs to replicate the entire /data/col1 area from source to destination and be considered a true form of disaster recovery. Which replication method should be used?
What is the current NAA type in the WWN format used within EMC Data Domain OS 5.4?
An EMC Data Domain customer has an environment with 10 branch offices whose backup data is replicated to their primary location. For disaster recovery purposes, the primary location is replicated to an offsite location.
Which replication topology does this represent?
An EMC Data Domain customer has configured replication of four directories created under the /data/col1/backup MTree with the following configuration:
They want to achieve the following:
1. Move these directories to MTrees
2. Consolidate the directories, where possible, to minimize the number of MTrees
3. Create new replication contexts
They do not plan to change the protocols used to access these locations. Which MTree setup will support this configuration change?
A customer has configured an MTree (/data/col1/departments) on an EMC Data Domain system with two subdirectories configured as Sales and HR. They want to configure replication to replicate only the Sales subdirectory to another Data Domain system. In addition, they do not want to replicate the HR subdirectory.
How can this be accomplished?
A customer wants to integrate an EMC Data Domain appliance into their current backup environment using CIFS, NFS, DD Boost, and VTL. Which backup application supports the four protocols?
A customer creates a DD Boost storage unit called "oracle". What is the path for this storage unit on the EMC Data Domain system?
In a Dell EMC Data Domain backup environment, what is used for writing to and reading from the backup targets in Veritas Backup Exec?
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?
When configuring backups to an EMC Data Domain system using VTL, what is a backup software recommendation for NetWorker?
Refer to the exhibit.
When monitoring the system show stats command output, you notice that the "Disk Write KiB/s" column does not have same data rate as "Net eth0a in MB/s" column. What is a possible reason for this behavior?
In a EMC Data Domain system, which user role allows creation of snapshots as well as import and export of tapes to a VTL library?
You have been tasked with configuring an NFS export on an EMC Data Domain for use on a Symantec NetBackup media server. The NetBackup media server is running Linux O/S. All configuration tasks were completed on the Data Domain.
You have created the NFS mount point, mounted the Data Domain NFS export, and created a directory for backups. After the first reboot, you notice that the Data Domain NFS exports are no longer mounted on the Linux media server.
Which file needs to be modified on the Linux media server to allow Data Domain to be mounted after reboots?
What is a characteristic of the Dell EMC Data Domain Cloud Tier with Retention Lock?
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?
How many slots per VTL are supported in a single Dell EMC Data Domain system?
