Which product should a consultant position to replace the existing solution and to add more features like iSCSI VTL support?
An engineer is implementing a D2D4312. What is the minimum number of concurrent backups to be configured for maximum performance?
If a language is selected other than English and some of the messages are in English, the firmware must be upgraded. What must you do to enable the required language?
Upgrade the language pack.
Housekeeping is an important task that is engineered to run as a low priority process but still needs a finite time to run. When does Housekeeping run when no blackout window has been set?
when a NAS file is closed
A customer is running a single site with multiple small servers and a few large servers. Previously, the servers were backed up to a direct attached tape drive. What should be done before beginning the design of a new solution?
Aggregate bandwidth bottlenecks between hosts and backup devices should be identified.
Your customer is having difficulty connecting to a NAS share on their D2D device. They took the following steps to configure the share: 1. They created an NFS share and mounted it on a Linux box. 2. They deleted the share on the D2D without unmounting it from the Linux box. 3. They recreated the share with the same name. They discovered that the issue was caused by using incorrect nodes for access. What should they do to fix the issue?
They should reboot the host Linux system.
When installing a D2D system, which configuration factors affect housekeeping?
setting specific blackout windows
When installing a D2D system, which statement is true about an HP StoreOnce Technology configuration?
Deduplication is automatic and there is no need to tell the dedupe software which backup application is being used.
