[All AWS-SysOps Questions]

A user has created an EBS volume of 10 GB and attached it to a running instance. The user is trying to access EBS for first time. Which of the below mentioned options is the correct statement with respect to a first time EBS access?

  • A. The volume will show a size of 8 GB
  • B. The volume will show a loss of the IOPS performance the first time
  • C. The volume will be blank
  • D. If the EBS is mounted it will ask the user to create a file system
Show Suggested Answer Hide Answer
Suggested Answer: B 🗳️
A user can create an EBS volume either from a snapshot or as a blank volume. If the volume is from a snapshot it will not be blank. The volume shows the right size only as long as it is mounted. This shows that the file system is created. When the user is accessing the volume the AWS EBS will wipe out the block storage or instantiate from the snapshot. Thus, the volume will show a loss of IOPS. It is recommended that the user should pre warm the EBS before use to achieve better IO

awscertified - you copy paste all the answers given by the website. where is the value you are adding with these comments? a lot of them are wrong. The explanation goes like this: "It is recommended that the user should pre warm the EBS before use to achieve better IO", while the AWS docs here ( https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-initialize.html ) state: "Empty EBS volumes receive their maximum performance the moment that they are created and do not require initialization (formerly known as pre-warming)."

This seems to be an outdated question. At that time answer B was the correct.

New EBS volumes receive their maximum performance the moment that they are available and DO NOT require initialization (pre-warming).

"the volume needed to be wiped cleaned before for new volumes, however pre-warming is not needed any more" https://jayendrapatil.com/tag/ebs/
