Demo Questions
Question 1
An IBM mainframe client has IBM DS8886 CKD storage installed. The customer has decided to use another new IBM DS8886 and use IBM Metro Mirror to provide a synchronous redundant copy of the data.
Which additional IBM software enables non-disruptive failover in the event of a storage hardware failure?
- IBM Remote Pair FlashCopy
- IBM Global Mirror
- IBM High performance FICON
- IBM HyperSwap
Correct answer: D
Explanation:
You can create an IBM HyperSwap topology system configuration where each I/O group in the system is physically on a different site. When used with active-active relationships to create HyperSwap volumes, these configurations can be used to maintain access to data on the system when power failures or site-wide outages occur.

Question 2
How are key management services provided for the IBM DS8886 storage system?
- SKLM
- Blockchain
- Full disk encryption
- Non-repudiation system
Correct answer: A
Explanation:
Full Disk Encryption (FDE) drive sets are used with key management services that are provided by IBM Security Key Lifecycle Manager (SKLM) software or Gemalto SafeNet KeySecure to allow encryption for data-at-rest on a DS8880.

Question 3
Which offering provides scale-out parallel processing and dramatically accelerates performance of analytics clusters when integrated with the IBM FlashSystem?
- IBM XIV
- IBM Spectrum Scale
- Real-time Compression
- IBM Spectrum Copy Data Management
Correct answer: B
Explanation:
Although Spectrum Scale and FlashSystem are both available by themselves, and there’s no requirement to combine them, doing so can result in the IT equivalent of “1+1=3.” Each solution complements the other in supporting the needs of two of today’s most common, fastgrowing “application ecosystems”—private clouds and [big] data analytics. Both of those application ecosystems must deliver extreme capacity and extreme performance simultaneously and economically. If only one or two of the scale/speed/economy attributes is needed, then each of the IBM products can stand alone very well. But where all three are prerequisites, the joint IBM solution shines.
