Exploring AWS EC2 and Storage Solutions

What is an EC2 instance type?

• A service for managing user permissions

• A type of Amazon S3 storage bucket

• An EC2 instance type is a specific configuration of CPU, memory, storage, and networking capacity for Amazon EC2 instances.

• A virtual machine for running databases

Name three instance families in AWS EC2.

• Storage Optimized

• Network Optimized

• General Purpose, Compute Optimized, Memory Optimized

• High Performance Computing

What is the purpose of Amazon EFS?

• To offer a content delivery network for static files.

• To serve as a backup solution for on-premises servers.

• The purpose of Amazon EFS is to provide scalable, shared file storage for AWS services and on-premises resources.

• To provide a database service for AWS applications.

How does Amazon S3 differ from EFS?

• Amazon S3 is object storage; EFS is file storage.

• Amazon S3 is used for block storage; EFS is for object storage.

• Amazon S3 supports NFS; EFS does not support NFS.

• Amazon S3 is file storage; EFS is object storage.

What are the different storage classes available in S3?

• Basic Storage

• Premium Storage

• Temporary Storage

• Standard, Intelligent-Tiering, Standard-IA, One Zone-IA, Glacier, Glacier Deep Archive

Explain the concept of bucket versioning in S3.

• Bucket versioning only allows for the deletion of objects in S3.

• Bucket versioning prevents any changes to objects in S3.

• Bucket versioning in S3 enables the storage of multiple versions of an object, allowing for recovery of previous versions.

• Bucket versioning is a feature that compresses objects in S3.

What is the maximum size of an S3 bucket?

• 10 TB per object

• Unlimited storage, 5 TB per object

• 1 TB per bucket

• 100 GB per bucket

How can you secure data stored in Amazon S3?

• Use only public access settings

• Store data without encryption

• Disable versioning for all buckets

• Use bucket policies, IAM roles, server-side encryption, versioning, and S3 Block Public Access.

What is the difference between standard and infrequent access storage classes in S3?

• Standard storage is for archival data; Infrequent access is for real-time access.

• Standard storage is cheaper than infrequent access; Infrequent access is for high-speed access.

• Standard storage is for frequent access; Infrequent access is for less frequent access.

• Standard storage is for temporary files; Infrequent access is for permanent storage.

How do you create an EC2 instance?

• Log in to AWS, go to S3, and create a bucket.

• Launch an instance without configuring security groups.

• Select an EC2 instance type and skip AMI selection.

• Log in to AWS, go to EC2, click 'Launch Instance', select AMI, choose instance type, configure details, add storage, set security group, and launch.
