6/4/22, 14:13 FlashSystem Fundamental Concepts Quiz: Attempt review Started on State Completed on Time taken Grade Feedback Thursday, April 1, 2021, 6:46 PM Finished Thursday, April 1, 2021, 6:54 PM 7 mins 37 secs 19.00 out of 25.00 (76%) A minimum of 19 correct answers is required to pass.Congratulations, you passed the FlashSystem Fundamental Concepts quiz. Question 1 Correct 1.00 points out of 1.00 What is a unique advantage of Distributed random array of inexpensive disks (RAID) 1 verses Traditional RAID 1 in terms of flexibility? Select one: The RAID groups must contain an even number of drives up to a total of 14 drives. The RAID groups must contain an odd number of drives up to a total of 15 drives. You can have any number of drives up to a total of 16. There is no advantage with Distributed RAID (DRAID) or Traditional RAID (TRAID) when dealing with level 1. Question 2 Correct 1.00 points out of 1.00 What is the only model of FlashSystem that cannot participate in a HyperSwap configuration? Select one: FlashSystem 5015 FlashSystem 5035 FlashSystem 9500 FlashSystem 7300 Question 3 Correct 1.00 points out of 1.00 Dynamic Distributed random array of inexpensive disks (DRAID) Expansion enables the size of a DRAID group to be non-disruptively increased by how many drives at a time? Select one: Up to 12 Up to 8 Up to 6 Up to 10 Question 4 Correct 1.00 points out of 1.00 What is a major advantage of Distributed random array of inexpensive disks RAID verses Traditional RAID? Select one: The spare drive is part of the active RAID group and delivers performance and value on a daily basis. DRAID 1 can be configured without a spare while TRAID 1 always requires a spare. You never need a spare when using Distributed RAID (DRAID) 5 versus Traditional RAID (TRAID) 5, and that saves money for the client. The spare is not part of the active RAID group and it remains pristine and ready for use when it is required.

Question 12 Correct 1.00 points out of 1.00 What happens if there is a drive failure while a Distributed RAID group is being dynamically expanded? Select one: The dynamic expansion will complete before the rebuild occurs DRAID 5 or DRAID 6 groups will automatically default to DRAID 1 for faster rebuilds The DRAID group (array) rebuild will take priority over the dynamic expansion Spectrum Virtualize will automatically transfer the affected data to a remote site Question 13 Correct 1.00 points out of 1.00 What is an easy story to tell clients regarding the relationship between FlashSystem 5200, 7300 and 9500? Select one: They only support DRAID6 with the new FCM3 drives Each increase costs 2X the previous model Each step up is 2X the physical size, 2X the # of host ports and 2X the performance Each step up is 2X the physical size, 2X the # of host ports and 2X the performance Cookie Preferences https://learn.ibm.com/mod/quiz/review.php?attempt=1131807&cmid=154097 3/6 6/4/22, 14:13 Question 14 Correct 1.00 points out of 1.00 FlashSystem Fundamental Concepts Quiz: Attempt review Redirect-on-Write FlashCopy is automatically used in which situation?

Select one: They are 1Gbe rather than 10GbE and can be used for host IO They are 1Gbe rather than 10GbE and can only be used for management There is no difference. They are the same as those on FlashSystem 7300 They are 1GbE rather than 10GbE but can be used for mgmt. and host IO Question 16 Correct 1.00 points out of 1.00 What allows Easy Tier to be extremely efficient with only a small amount of high-performance flash? Select one: Manual tuning to tweak settings for rapidly changing environments Role Based Access Control (RBAC) enables flash efficiency Sub-Logical Unit Numbering (LUN) tiering Policy settings rather than automated adjustments Question 17 Incorrect 0.00 points out of 1.00 Drive Write Per Day (DWPD) measurements were important at one time. What development has largely rendered DWPD measurements pointless? Select one: Quad-level cell (QLC) flash does not function the same way as triple-level cell (TLC) or single-level cell (SLC) flash thereby rendering DWPD comparisons pointless. Flash drive sizes have become large enough that it is nearly impossible to write the full capacity of a drive in a single day. DWPD is still extremely important and should be part of every client discussion in a sales opportunity. Flash has become so reliable that it no longer makes sense to focus on potential DWPD values.
