Which of the following is not a true statement relating to the performance of your EBS volumes?

Your EBS volumes do not seem to be performing as expected and your team leader has requested you look into improving their performance.

Which of the following is not a true statement relating to the performance of your EBS volumes?
A .  Frequent snapshots provide a higher level of data durability and they will not degrade the performance of your application while the snapshot is in progress.
B .  General Purpose (SSD) and Provisioned IOPS (SSD) volumes have a throughput limit of 128 MB/s per
volume.
C .  There is a relationship between the maximum performance of your EBS volumes, the amount of I/O you are driving to them, and the amount of time it takes for each transaction to complete.
D .  There is a 5 to 50 percent reduction in IOPS when you first access each block of data on a newly created or restored EBS volume

Answer: A

Explanation:

Several factors can affect the performance of Amazon EBS volumes, such as instance configuration, I/O characteristics, workload demand, and storage configuration.

Frequent snapshots provide a higher level of data durability, but they may slightly degrade the performance of your application while the snapshot is in progress. This trade off becomes critical when you have data that changes rapidly. Whenever possible, plan for snapshots to occur during off-peak times in order to minimize workload impact.
