The exhibit displays the values for the default adaptive QoS policy. An administrator assigns the Value policy to a 1 TB volume. Over time, the volume expands to
3 TB.
What is the peak IOPS for the volume, both before and after the expansion? (Choose the best answer.)
The peak IOPS for a volume is determined by the default adaptive QoS policy values provided. For the Value policy, the peak IOPS per TB is 512. Initially, the volume is 1 TB, so the peak IOPS is 512 IOPS. When the volume expands to 3 TB, the peak IOPS scales proportionally, resulting in 512 IOPS per TB multiplied by 3 TB, which equals 1536 IOPS.
Answer is B [-expected-iops-allocation {used-space|allocated-space}] - Expected IOPS Allocation Specifies the expected IOPS allocation policy. The allocation policy is either allocated-space or used-space. When the expected-iops-allocation policy is set to allocated-space, the expected IOPS is calculated based on the size of the storage object. When the expected-iops-allocation policy is set to used-space, the expected IOPS is calculated based on the amount of data stored in the storage object taking into account storage efficiencies. The default value is allocated-space. [-peak-iops-allocation {used-space|allocated-space}] - Peak IOPS Allocation Specifies the peak IOPS allocation policy. The allocation policy is either allocated-space or used-space. When the peak-iops-allocation policy is set to allocated-space, the peak IOPS is calculated based on the size of the storage object. When the peak-iops-allocation policy is set to used-space, the peak IOPS is calculated based on the amount of data stored in the storage object taking into account storage efficiencies. The default value is used-space.
B Peak IOPS of 512 per 1TB, 512 x 3 = 1536
Agree B
Peak = used TB Expected = allocated TB Ans: A
peak-iops is the maximum possible IOPS per allocated or used TB|GB. Please RTFM : https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.pow-perf-mon%2FGUID-B144F39A-2E14-4048-91CA-D8080C50F70D.html So for me if it's B
You're right : peak-iops is the maximum possible IOPS per allocated or used TB|GB. Means B is the good one.
I feel it is "C" Reference: http://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.pow-perf-mon%2FGUID-B144F39A-2E14-4048-91CA-D8080C50F70D.html
B. Value Policy: Peak 512 IOPS per TB 1TB volume= Peak 512 IOPS 3TB volume= 512*3 = Peak 1536 IOPS
