A user is trying to create a PIOPS EBS volume with 8 GB size and 200 IOPS. Will AWS create the
volume?
A.
Yes, since the ratio between EBS and IOPS is less than 30
B.
No, since the PIOPS and EBS size ratio is less than 30
C.
No, the EBS size is less than 10 GB
D.
Yes, since PIOPS is higher than 100
Explanation:
A provisioned IOPS EBS volume can range in size from 10 GB to 1 TB and the user can provision
up to 4000 IOPS per volume. The ratio of IOPS provisioned to the volume size requested should
be a maximum of 30; for example, a volume with 3000 IOPS must be at least 100 GB.
A
A (30:1) (iops: volume)
A
Because the min provisioned IOPS [PIOPS] can be as low as 4 GB. See middle column. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html
Answer is A to pass exam
The answer is D. The minimum number of IOPS per volume is 100.
Where does it say anything about 30:1 ratios?
At this link, 2nd paragraph under “Provisioned IOPS SSD (io1) Volumes” http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html
“An io1 volume can range in size from 4 GiB to 16 TiB and you can provision 100 up to 20,000 IOPS per volume.”
A is correct
