25
Fill in the blank: EBS volumes can be __________ to maintain data integrity during failures.
snapshotted
26
What AWS service allows the restoration of EBS snapshots?

28
True or False: EBS volumes can be automatically backed up using lifecycle policies.
True
29
What is the main advantage of using SSD over HDD for EBS?
Faster read and write performance
30
What happens to data on an EBS volume when the associated EC2 instance is terminated?
Data remains intact unless the volume is set to delete on termination.
31
What is the maximum number of EBS volumes that can be attached to a single EC2 instance?
28 volumes
32
True or False: EBS volumes can be resized while in use.
True

Allows multiple EC2 instances to access a single EBS volume concurrently.
34
Fill in the blank: EBS volumes can be __________ to improve performance.
provisioned with IOPS
35
What AWS service provides metrics for EBS volumes?
Amazon CloudWatch
36
