Demo Questions

Question 1
Which prerequisites must be fulfilled before starting the array initialization? (Choose three)
  1. HPE Nimble Windows Toolkit installed on a server/laptop.
  2. Ensure your laptop/server IP has a static IP address configured on the same subnet as the array management interface.
  3. Array updated to the latest firmware.
  4. All switch configurations done like flow control and spanning tree.
  5. Array registered in InfoSight based on the serial number.

Question 3
What is the maximum number of banks in an AF-Series array?
  1. 1
  2. 2
  3. 3
  4. 4
Correct answer: B
Question 4
What is a valid QoS performance setting?
  1. latency threshold
  2. IOPS minimum
  3. IOPS limit
  4. MB/s minimum
Correct answer: C
Explanation:
QoS-Limit allows a user to limit either the IOP or MB/s performance of a specific workload.  Having the ability to limit both IOPS and MBs is important as quite often any single workload will have different peaks and troughs during the operational day.  For instance, an OLTP workload maybe very latency sensitive to small block updates during the working day when rows and tables are frequently being accessed or updated (this will tend to be very IOP/latency sensitive) yet in the evening the same database maybe receiving feeds from other systems (or providing bulk updates/analysis or index rebuilds), the same application will cease to be IOP sensitive and will now be bandwidth (MBs) sensitive.  In NimbleOS4 a user can limit a workload by either IOPS or MBs and also specify limits to both IOPS and MBs.  If either limit is reached then the volume will be restricted accordingly. Reference: https://community.hpe.com/t5/HPE-Storage-Tech-Insiders/NimbleOS-4-Quality-of-Service-QoS-Limits/ba-p/6986455#.XBEAvMRR2kw

Question 5
What are primary HPE Nimble SmartReplicate components? (Choose three.)
  1. partner
  2. snapshot schedule
  3. replication group
  4. sync partner
  5. throttle
Correct answer: ABE
Question 6
How should the All-Flash shelf be connected to the controller shelf?
  1. Cable the All-Flash shelf directly to the last disk shelf.
  2. Cable the All-Flash shelf directly to the controller shelf.
  3. Use high performance SAS expanders.
  4. Cable the All-Flash shelf directly to the first disk shelf.
Correct answer: B
Question 7
What is the correct power on/off order of the All Flash-Series? (Choose two.)
  1. power off the controller shelf first, then the expansion shelves
  2. power on controller shelf first, then the expansion shelves
  3. power on expansion shelves first, then the controller shelf
  4. power off the expansion shelves first, then the controller shelf
Correct answer: AC
