質問 1：
A customer has submitted an REP for which a DS8870 is the preferred solution to support their VMware environment. They require support for VAAI Extended Copy.
What should the technical specialist advise this customer?
A. DS8870 supports the VAAI functionality required by this customer
B. A SAN Volume Controller must be proposed along with the DS8870 to provide VAAI support
C. VAAI is only a host function so any disk subsystem can be considered
D. A DS8870 with FlashCopy should be proposed
正解：A
質問 2：
A customer is looking to open a new data center and has asked about raised floor requirements to accommodate cabling for the DS8870.
What is the correct response?
A. Only a DS8870 with business class cabling can have top exit power cables
B. D38870 power cables can only be connected under the floor as DS8870 always requires a raised floor for cooling purposes
C. There is a feature which allows power and EC cables to exit from the top of the DSSS7O frames
D. An RPQ is needed to allow top exit cabling for a DSSSJO with any expansion frames
正解：C
質問 3：
When Global Mirror and the local disk subsystem fails it usually is not possible to recover because the subsystem stops responding. The SNMP then sends the alerts that indicate there is a problem.
What triggers the initial recovery actions?
A. Total Storage Productivity Center for Data
B. Once the SNMP alerts have been received the process will restart automatically
C. The SNMP alerts are enough to trigger the recovery and then fix the problem
D. The problem can be fixed manually once the SNMP alerts are spotted
正解：D
質問 4：
A customer wants to add a new DSS8OFJ into a data center that is already in production. How is it possible to verify that the DS8800 is supported into the customer's SAN and server infrastructure?
A. Check the interoperability matrix
B. The D58800 is compatible with every SAN infrastructure
C. Check the System Storage Interoperation Center
D. If there are other DS8000 systems in the data center there is no need to check for any compatibility
正解：C
質問 5：
A customer has a UNIX-based 25 TB Oracle/SAP instance currently running on an HP 12000 Enterprise Storage array. The database is very sensitive to response times and is reported to have a peak I/O requirement of over 25,000 I/O per second. The HP device is nearly three years old, and the customer is considering replacing it.
Which of the following is the best way to investigate the IBM DS8000 as a suitable technology replacement for the HP 12000 device?
A. Use the Internet to find out the capabilities of an HP 12000 Storage Array and configure an equivalent IBM D58800.
B. Ask the customer if they can estimate the workload characteristics.
C. Ask the customer on what basis HP sized the HP 12000 Storage Array originally, and make an assessment from that information.
D. Ask the customer for IOSTAT output from the server or servers and use it as an input to a Disk Magic model.
正解：D
質問 6：
Which statement is true of the Easy Tier feature on DS8000?
A. It is a priced feature by terabytes used.
B. It will operate in a homogeneous pool.
C. It requires SSDs to be added to a heterogeneous pool to operate.
D. It handles data in 256 MB chunks.
