IBM C9020-668 Exam Actual Questions

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?

Correct Answer: D 🗳️
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.

Which offering provides scale-out parallel processing and dynamically accelerates performance of analytics clusters when integrated with the IBM FlashSystem?

Correct Answer: B 🗳️
Although Spectrum Scale and FlashSystem are both available by themselves, and theres 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.

A customer has an older IBM storage subsystem and wants to know where to find the Service Discontinued data for the product.
What should the technical specialist tell the customer?

Correct Answer: D 🗳️
When service is discontinued, corrections to known problems remain available, but the development team is redirected to other work, and no new, tested corrections will be generated for general use. Known problems may be reviewed and ordered via electronic vehicles such as the internet (e.g., http:// www.ibm.com/support) however support provided by the IBM Client Support representatives, will be discontinued.
