A developer needs to attach a persistent storage volume to an EC2 instance for a database that requires frequent updates. Which AWS service should be used?

• Amazon S3
• Amazon EFS
• Amazon EBS
• Amazon S3 Glacier

If a company wants to optimize its storage costs without compromising on performance for an application with moderate I/O requirements, which EBS volume type should they choose?

• Provisioned IOPS SSD
• General Purpose SSD
• Throughput-Optimized HDD
• Cold HDD

A team finds their application's storage requirements have increased. Which feature of Amazon EBS allows them to resize the volume dynamically?

• Snapshot feature
• Elastic volumes
• Volume replication
• Throughput optimization

For creating a disaster recovery solution, what feature of Amazon EBS should a company leverage?

• Throughput optimization
• IOPS optimization
• Snapshots
• Elastic volumes

A company needs to copy their EBS snapshots to another region for compliance reasons. What additional cost should they be aware of?

• Cost of snapshots in the source region
• Data transfer cost across regions
• Elastic volume modification fees
• Provisioning additional IOPS

For an application that requires temporary storage of data that changes frequently, which storage option is more appropriate?

• Amazon S3
• Amazon EBS
• Instance Store
• Amazon S3 Glacier

A database on AWS requires high IOPS for optimal performance. Which EBS volume type should be selected?

• General Purpose SSD
• Magnetic
• Provisioned IOPS SSD
• Throughput-Optimized HDD

How does Amazon EBS ensure high availability and durability for its volumes?

• By replicating volumes within the same region
• Through automatic replication within its Availability Zone
• By creating snapshots periodically
• Using elastic volumes for dynamic resizing

If a company needs to update a single character in a large file frequently, which storage type should they use for better performance?

• Block storage
• Object storage
• Ephemeral storage
• Cold storage

When estimating costs for an EBS volume, which factors contribute to the overall cost?

• Size of the volume and number of I/O operations
• Size of the volume and data transfer rates
• Number of I/O operations and data transfer rates
• Size of the volume and amount of provisioned IOPS
