What is the next step after making a backup of your fabric configuration before making changes to the active zone set?
A. Create a new zones
B. Activate change tracking
C. Disable the active zone set
D. Copy the active zone set
The customer has an existing fabric switches installed from one manufacturer. They have decided to add a redundant fabric using switches from a different manufacturer. Interoperability is their main concern. What is important when considering interoperability in the SAN?
A. switch interoperability mode
B. HBA firmware/driver code
C. zone naming convention
D. virtualization engine
Last month, you successfully merged two (2) local SAN islands into a single core/edge fabric topology and connected storage devices to the core switches. Performance benchmarks were met or exceeded. In recent days, server administrators have documented a slow down in performance as I/O demands have increased. Storage administrators report that all storage ports are underutilized. What is the most likely explanation?
A. conflicts between SAN routing protocols
B. storage port buffer credit limits have restricted I/O capabilities
C. multiple process login failures
D. over utilitization of one or more ISLs
A fourway cluster is attached to two fabrics. Each member has two HBAs connected to each fabric. Each fabric has two subsystem connections. Each cluster member is a primary for one application. All LUNs appear on all storage ports with workload equally distributed across all. Each host has two dedicated HBAs for tape that can each see four independent LTO II (35MB/s) tape drives. All files are large and involve sequential I/O. Performance reporting shows a large read pending at the host during multi threaded backup. What is the most probably cause for the large read pending at the host?
A. native command queueing
B. SCSI Queue Depth too high
C. SCSI Queue Depth too low
D. throttling threshold is too high
What should the administrator verify before connecting a standalone populated switch to an existing fabric?
A. Verify port type assignment
B. Verify domain ID assignment
C. Verify FC_ID port assignment
D. Verify principle switch assignment
You are the system administrator of a mediumsized manufacturing company. The chief executive officer (CEO) is concerned about business continuity in case of a disaster. He constituted a project team to develop a business continuity and disaster recovery solution. The team is discussing replication strategies. What two (2) dependencies need to be considered in timetocreate and incremental re establishment of a split mirror? (Choose two.)
A. LUN size
B. file system
C. changed data
D. LDM
E. sector size
Which set of SCSI components are required to support SCSI command tag queueing?
A. adapter, adapter driver, device, device driver
B. adapter, device, device driver
C. adapter, device driver, controller, controller firmware
D. device, device driver
A customer has a SASbased storage environment with a SAS domain and some standalone servers, each with multiple builtin SAS disks. The implementation includes direct routing, table routing and subtractive routing. Which role does a fanout expander play in subtractive routing?
A. It routes between edge expanders connected to it.
B. It forwards routing requests to all other connected edge expanders.
C. It disables currently unused branches to increase throughput.
D. It is the sole source of subtractive routing requests in the SAS domain.
A HBA has failed in an application server that connects to a Fabric that uses WWPN zoning. Which two (2) steps should be completed after replacing the HBA to bring the application server back online? (Choose two.)
A. Change the zone configuration.
B. Change the application metadata server.
C. Change the WWPN login of the HBA.
D. Change the LUN masking configuration.
You have recently upgraded a tape drive on a older switch to operate at 120MB/s from 80MB/s. Prior to purchasing the tape drives, you tested server dumps to a disk array across multiple ports and saw speeds exceeding 150MB/s. With the new tape drive, you have not seen any dump speed exceed 100MB/s. What is the most likely cause?
A. The new tape drive has logged into the fabric as a storage initiator.
B. The switch only has 1Gb/s ports.
C. You have not yet reset the switch port buffer credits.
D. The tape drive has logged in as an iSCSI device.
