This exam has an Assessment Exam option: A9020-668 Assessment: IBM Storage Technical V1

Assessment exams are web-based exams that provides you, at a cheaper costs, the ability to check your skills before taking the certification exam.

This assessment exam is available in: English
Passing the exam does not award you a certification, and it is only used to help you assess if you are ready or not to take the certification exam.

You can register for it at Pearson VUE and it will provide you a score report, showing you how you did in each section.

All IBM certification tests presume a certain amount of "on-the-job" experience which is not present in any classroom or Web presentation. The recommended courses and links will help you gain the skill and product knowledge represented in the test objectives. They do not teach the answers to the test questions, and are not intended to do so. This information may not cover all subject areas in the certification test, or may contain more recent information than is present in the certification test. Taking these or any classes will not guarantee that you will achieve certification

QUESTION 1
Which solution meets a customer’s requirements for 100,000 IOPS, lowest latency, and maximum TB of raw capacity for an Oracle database?

A. IBM FlashSystem A9000
B. IBM Storwize V7000F
C. IBM FlashSystem V9000
D. IBM FlashSystem 900

Answer: D

Explanation:
IBM FlashSystem 900 is designed to accelerate the applications that drive business – like those using an Oracle Database.
IBM FlashSystem 900 can scale usable capacity from as low as 2 TB to as much as 57 TB in a single system.
FlashSystem 900 delivers Tier 0 top application performance with up to 1.1 million 100% random read IOPS and 600,000 100% random write IOPS.


QUESTION 2
Which non-concurrent capacity upgrade is possible for a customer with an IBM FlashSystem 900?

A. Systems purchased with eight 2.9 TB flash modules can be expanded to twelve 2.9 TB flash modules.
B. Systems purchased with eight 5.7 TB flash modules can be expanded to twelve 2.9 TB flash modules.
C. Systems purchased with eight 1.2 TB flash modules can be expanded to twelve 2.9 TB flash modules.
D. Systems purchased with eight 1.2 TB flash modules can be expanded to twelve 5.7 TB flash modules.

Answer: A

Explanation:
FlashSystem 900 can be populated with up to 12 x 1.2 TB IBM MicroLatency modules in increments , 6, 8, 10, or 12; or up to 12 x 2.9 TB or 5.7 TB IBM MicroLatency modules
in increments , 8, 10, or 12.
These modules of either 1.2 TB, 2.9 TB, or 5.7 TB cannot be intermixed. Capacity can be upgraded by purchasing the AF23 (1.2 TB), AF24 (2.9 TB)) or AF25 (5.7 TB) IBM MicroLatency module feature codes as MES upgrades. Here are the upgrade paths:

QUESTION 3
A customer is interested in purchasing an IBM TS7650G ProtecTIER Gateway for its production site and one for replication at its DR site. The DR site is a target only site.
How is the cost of the solution affected by the replication?

A. ProtecTIER replication is included with base license.
B. ProtecTIER replication is included with hardware and no license is required.
C. ProtecTIER replication licensing is required at both sites.
D. ProtecTIER replication licensing is required at the primary site only.

Answer: C

Explanation:
You must have a license for the replication feature for each ProtecTIER server in the replication grid.

QUESTION 4
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?

A. Check IBM Digital Techline Center.
B. Check IBM SSIC webpage.
C. Check the IBM sales manual.
D. Check the IBM Knowledge Center.

Answer: D

Explanation:
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.
