D. 6
Answer: B
Q54. An engineer is configuring a storage array in a mixed environment of 10 Gb iSCSI and 16 Gb Fibre Channel. The 10 Gb iSCSI network consists of two separate VLANs and is used for server connectivity. The 16 Gb Fibre Channel network consists of a single fabric and is used to provide high-speed replication connectivity to a secondary storage array for Synchronous Live Volume with Auto Failover.
How many fault domains must the engineer configure on the storage array for each network?
A. One fault domain for iSCSI and two fault domains for Fibre Channel
B. One fault domain for Fibre Channel and one fault domain for iSCSI
C. Two fault domains for iSCSI and one fault domain for Fibre Channel
D. Two fault domains for Fibre Channel and two fault domains for iSCSI
Answer: C
Q55. An engineer has installed an SC4020 with four FC ports in each controller. This is a dual-fabric installation with four FC connections in each server. The servers use the OS built-in multi-pathing capabilities.

A. Too many volumes are mapped to the server from one controller.
B. The switch zoning is incorrectly configured.
C. The server HBA timeouts are set incorrectly.
D. The multi-pathing software is incorrectly configured.
Answer: C D
Q56. A customer needs to monitor their database volumes to make sure the storage capacity does NOT exceed the desired limits.
What should the engineer do to automate this monitoring for the database volumes?

A. sa account credentials
B. domain user account credentials
C. domain backup account credentials
D. local administrator account credentials
Answer: B
Q58. An engineer needs to install an SC8000 with four FC ports in each controller and two FC switches set up in a dual fabric. Each controller also has two 10 Gb iSCSI ports. All iSCSI ports are connected to an ethernet switch. The system uses virtual ports.
How many fault domains are required?
A. 3
B. 5
C. 4
D. 2
Answer: C
Q59. An engineer needs to use a set of commands to initialize a new SC8000 with serial numbers 12345 & 12346 from the CLI.
Which initial set of commands should the engineer choose?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q60. 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
Q61. A customer has mapped a volume to a Windows 2008 server using two 16 Gb FC paths and two 1 Gb iSCSI paths. The customer needs the traffic to split equally across only the two FC paths without using iSCSI under normal conditions. If the FC network is down, traffic should failover to the iSCSI paths to maintain connectivity.
Which Windows 2008 multi-pathing policy should be used?
A. Round Robin With Subset
B. Fail Over Only
C. Least Queue Depth
D. Round Robin
Answer: A

Q62. A customer has replication configured between its primary and DR sites. When does a customer need to update QoS node settings?
A. A security audit has found a substantial portion of unencrypted traffic between sites.
B. The number of volumes being replicated between sites has doubled.
C. Additional storage capacity was added to the production system.
D. The bandwidth between sites has been upgraded.
Answer: D
Q63. 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.
What should the engineer conclude?
A. Flow control is disabled on the array.
B. High TCP/IP retransmits are causing pause frames.
C. The ISL bandwidth is exceeded.
D. Spanning tree convergence is pausing IO.
Answer: B
Q64. Refer to the exhibit.
