Answer: B D
Q10. An engineer updates the SCOS version from 6.5.x to 6.6.x on an SC4020 via ISO. The engineer uses the following credentials: admin / admin. The engineer calls Dell Support for final health checks and is informed that a newer SCOS 6.6.x version is available. The engineer tries to perform another ISO update to the newest SCOS 6.6.x version. The engineer is unable to log back in to the BMC interface to start the ISO update.
What should the engineer do to update the newest SCOS version via ISO?
A. use the login credentials root/ calvin in SCOS 6.6.x
B. update Java to version 8 to use the updated BMC interface
C. downgrade Java to version 7 from version 8
D. request Dell Support to reset the expired admin password
Answer: A
Q11. Refer to the exhibit.
An engineer needs to correctly configure the fault domain on the Storage Array for the dual-fabric Fibre Channel environment shown. Full connectivity and failover from the storage array configured in legacy port mode for the servers in this environment are required.
Which fault domain configuration meets the requirements?
A. A fault domain that contains P4, P3, P2, and P1; and a fault domain that contains R4, R3, R2, and R1
B. A fault domain that contains P4, R4, P3, and R3; and a fault domain that contains P2, R2, P1, and R1
C. A fault domain that contains P4 and R4, a fault domain that contains P3 and R3, a fault domain that contains P2 and R2, and a fault domain that contains P1 and R1
D. A fault domain that contains P4 and P3, a fault domain that contains R4 and R3, a faultdomain that contains P1 and P2, and a fault domain that contains R1 and R2
Answer: B
Q12. A customer has multiple Storage Centers at their main site and a DR system at a remote site. A particularly important volume requires High Availability protection. An outage on one system at the main location must NOT cause data to be inaccessible. Disaster Recovery protection is also required to protect data even if the entire main site goes down.
Which technology best meets these requirements?
A. Asynchronous Replication
B. LiveVolume Managed Replication
C. Fluid Data Architecture
D. Synchronous Replication
Answer: B
Q13. An engineer has several servers connected to the Storage Center through two FC fabrics. The Storage Center runs in Virtual Ports mode. The engineer needs to create zones based on World Wide Names (WWN).

B. only the Virtual WWNs
C. both the Primary and Reserve WWNs
D. both the Virtual and Physical WWNs
Answer: B
Q14. A Storage Administrator wants to do a Storage Center OS update to SCOS version 6.7.5. The Storage Center is currently at SCOS version 6.5.30. The Storage Center is at a secure facility and does NOT allow connectivity to any network outside the facility. The Storage Administrator is trying to use the Storage Center Update Utility to accomplish this task, but has been unsuccessful in doing so.
Why has the Storage Administrator been unsuccessful?
A. The Storage Center hasNOTpassed Pre-Upgrade checks and is blocking the update from occurring.
B. The secure facility is NOTallowing the StorageAdministrator’s laptop to connect to the Storage Center across the network.

B. 5
C. 4
D. 2
Answer: C
Q16. An engineer is investigating network congestion on the iSCSI network and finds pause frames are rapidly incrementing on all host and ISL switch ports, but NOT on the array switch ports. All switch ports are configured for both send and receive flow control.
