質問 1：
A customer has a terabyte database and is required to back up the data daily. The SLA has allotted 6 hours for completion of the backup from 7:00 P.M. until 1:00 A.M. However, the customer has a tape library with only five SDLT tape devices running at native speeds of 40 GB/hour. Which two should you do to successfully meet the expected SLA requirements? (Choose two.)
A. Prioritize the schedule to launch during periods of greatest inactivity
B. Enable server-based compression
C. Interleave data streams
D. Use multiple data streams across multiple devices
正解：C,D
質問 2：
Which two data protection techniques provide the highest level of data protection and rapid recovery? (Choose two.)
A. Backup to disk combined with RAID disk data protection.
B. Local mirroring with backup to tape.
C. RAID-0 with mirrored write back cache and battery backup.
D. Remote mirroring with consistency groups and backup to alternate storage.
正解：A,D
質問 3：
A company is designing a Disaster Recovery (DR) plan. They have an RPO of zero. The DR site is located 250km from the production site. The DR plan must not affect application performance at the production facility. Which scenario is appropriate?
A. Asynchronously replicated the data to the DR site
B. A new DR site must be chosen
C. Synchronously replicated the data to the DR site
D. Create a split mirror snapshot and replicate the snapshot to the DR site
正解：B
質問 4：
Given point-to-point, bus, loop and Fabric topologies, which solution would be considered a mixed topology approach using three separate but interconnected topologies?
A. A mixed Serial ATA (SATA) and Serial Attached SCSI (SAS) solution using expanders where the SATA disks and the SAS disks share connectivity to the expanders
B. An Ethernet-basediSCSI storage network using Ethernet hubs connected to Ethernet switches with the storage devices directly attached to switches and the servers connected to hubs
C. A cluster of servers connecting to Ethernet switches with a combination NAS Gateway Object storage system for file sharing and block access
D. AFibre Channel-based storage network using Fabric switches with both loop attached and point-to-point attached servers and storage
正解：D
質問 5：
An existing SAN has been experiencing numerous faults in the past few months, you have been Tasked with bringing the problems to solution and ensure reliability. Your primary concern is visibility into the SAN and the present lack of monitoring. Which two are true about the existing infrastructure? (Choose two)
A. Requesting vendor assistance, and if need be custom builds of the firmware/software that runs your array to fix the specific problems that you encounter.
B. Since SMI-S is an emerging standard, the likehood of being able to manage equipment bought in previous years is very low. A migration plan should be considered to an SMI-S complaint infrastructure.
C. Evaluating vendor supplied tools, and knowledge base type documents may outline best practices for increasing reliability and reporting.
D. Testing and then Level settings firmware and code levels to a common vendor supported standard will allow you to avoid many of the problems that may have been encountered in the past.
正解：C,D
質問 6：
When implementing a LAN-free/severless (third party copy) backup solution, which benefit is achieved?
A. SINCE THE BACKUP ISlan-FREE ALL BACKUP DATA TRAFFIC IS RELEGATED TO THE san
B. The combination of 3rd party copy and incremental backups allows significant reduction of tapes needed.
C. Since the backup isserverless no backup servers are required.
D. The third party copy protocol will handle all open files so no snapshots or dataquiesce is required
正解：A
質問 7：

A. 8
B. 4
C. 15
D. 12
