Which of the following is a key characteristic of Amazon Elastic Block Store (EBS) in EC2?

• EBS is an ephemeral storage solution.

• EBS volumes automatically scale with usage without resizing.

• EBS is designed for unstructured data storage like object storage.

• EBS volumes can only be attached to a single EC2 instance at a time.

Which statement about Amazon Elastic Block Store (EBS) is correct?

• EBS volumes are only accessible when the EC2 instance is in the same region.

• EBS is a persistent block storage designed for use with Amazon EC2 instances.

• EBS automatically scales storage capacity based on usage.

• Data stored on EBS is lost when an EC2 instance is stopped.

Which of the following is a key characteristic of Amazon Elastic Block Store (EBS)?

• EBS provides temporary storage that is deleted when the EC2 instance is terminated.

• EBS volumes are automatically accessible across multiple regions.

• EBS allows you to create snapshots that can be used to restore data or migrate volumes.

• EBS scales automatically to handle storage size changes without manual intervention.

Which of the following statements about Amazon Elastic Block Store (EBS) is not true?

• EBS volumes support encryption at rest using AWS-managed or customer-managed keys.

• EBS volumes can be detached from one EC2 instance and attached to another in the same Availability Zone.

• Snapshots of encrypted EBS volumes cannot be shared across accounts.

• EBS General Purpose SSD (gp3) volumes provide consistent IOPS performance independent of storage capacity.

What is Amazon Elastic Block Store (EBS) primarily used for in AWS?

• Temporary storage that is deleted when an EC2 instance stops.

• Persistent block storage for EC2 instances.

• Object storage for unstructured data like images and videos.

• Distributed file system for high-performance computing.

Which of the following is a key difference between Amazon Elastic Block Store (EBS) and Instance Store?

• EBS provides temporary storage, while Instance Store offers persistent storage.

• Instance Store supports snapshots for data backup, while EBS does not.

• EBS volumes can be detached and re-attached to instances, whereas Instance Store is tied to the lifecycle of the instance.

• EBS is designed for caching, while Instance Store is for long-term data storage.

Which of the following statements correctly describes the difference between Amazon Elastic Block Store (EBS) and Instance Store?

• EBS is suitable for temporary data storage, while Instance Store is designed for long-term data storage.

• Instance Store supports encryption by default, while EBS does not support encryption.

• EBS data persists independently of the instance, while Instance Store data is lost when the instance is stopped or terminated.

• Instance Store volumes can be detached and re-attached to different instances, while EBS volumes cannot.

Which of the following is true about Amazon EC2 Instance Store?

• Instance Store data persists even after the instance is stopped or terminated.

• Instance Store is a temporary storage that is physically attached to the host running the EC2 instance.

• Instance Store volumes can be detached and re-attached to different EC2 instances.

• Instance Store supports snapshots for data backup.

Which of the following is a characteristic of Amazon EC2 Instance Store?

• Instance Store volumes are automatically backed up and can be restored after an instance is terminated.

• Instance Store provides persistent storage that remains intact even when the EC2 instance is stopped or terminated.

• Instance Store is typically used for temporary data storage, such as caching, buffer storage, and data that doesn't need to persist after an instance is stopped.

• Instance Store can be used with all types of EC2 instances, including those in all availability zones.

Which of the following is a key feature of Amazon Elastic File System (EFS) in EC2 storage options?

• EFS is used for temporary storage and is deleted when the EC2 instance is stopped.

• EFS provides a scalable, network-attached file system that can be accessed by multiple EC2 instances concurrently.

• EFS only supports one EC2 instance connection at a time, making it unsuitable for shared file access.

• EFS requires users to provision and manage storage capacity, unlike other AWS storage options like EBS.
