S3/EBS/EFS and Azure Storage

In the AWS platform, cloud storage is primarily broken down into three services:

• Simple Storage Service (S3). Basic object storage that makes data available through an Internet accessible API.

• Elastic Block Storage (EBS). Block level storage intended for access by a single VM.

• Elastic File System (EFS). File storage meant for use as shared storage for up to thousands of EC2 instances.

In Azure Storage, subscription-bound storage accounts allow you to create and manage the following storage services:

• Blob storage stores any type of text or binary data, such as a document, media file, or application installer. You can set Blob storage for private access or share contents publicly to the Internet. Blob storage serves the same purpose as both AWS S3 and EBS.

• Table storage stores structured datasets. Table storage is a NoSQL key-attribute data store that allows for rapid development and fast access to large quantities of data. Similar to AWS' SimpleDB and DynamoDB services.

• Queue storage provides messaging for workflow processing and for communication between components of cloud services.

• File storage offers shared storage for legacy applications using the standard server message block (SMB) protocol. File storage is used in a similar manner to EFS in the AWS platform.

A team is building an HTML form that is hosted in a public Amazon S3 bucket. The form uses JavaScript to post data to an Amazon API Gateway API endpoint. The API endpoint is integrated with AWS Lambda functions. The team has tested each method in the API Gateway console and has received valid responses.

Which combination of steps must the team complete so that the form can successfully post to the API endpoint and receive a valid response? (Select TWO.)

1. A)  Configure the S3 bucket to allow cross-origin resource sharing (CORS).

2. B)  Host the form on Amazon EC2 rather than on Amazon S3.

3. C)  Request a quota increase for API Gateway.

4. D)  Enable cross-origin resource sharing (CORS) in API Gateway.

5. E)  Configure the S3 bucket for web hosting.
