A company is building an application to accept data from customers. The data must be encrypted at rest and in transit.
The application uses an Amazon API Gateway API that resolves to AWS Lambda functions. The Lambda functions store the data in an Amazon Aurora MySQL DB cluster. The application worked properly during testing.
A developer configured an Amazon CloudFront distribution with field-level encryption that uses an AWS Key Management Service (AWS KMS) key. After the configuration of the distribution, the application behaved unexpectedly. All the data in the database changed from plaintext to ciphertext.
The developer must ensure that the data is not stored in the database as the ciphertext from the CloudFront field-level encryption.
Which solution will meet this requirement?
A developer is creating a simple proof-of-concept demo by using AWS CloudFormation and AWS Lambda functions The demo will use a CloudFormation template to deploy an existing Lambda function The Lambda function uses deployment packages and dependencies stored in Amazon S3 The developer defined anAWS Lambda Function resource in a CloudFormation template. The developer needs to add the S3 bucket to the CloudFormation template.
What should the developer do to meet these requirements with the LEAST development effort?
S3BucketandS3Key:These properties in a CloudFormationAWS::Lambda::Functionresource specify the location of the function's code in S3.
Least Development Effort:This solution minimizes code changes, relying on CloudFormation to reference the existing S3 deployment package.
A developer is creating an AWS CloudFormation template to deploy Amazon EC2 instances across multiple AWS accounts. The developer must choose the EC2 instances from a list of approved instance types.
How can the developer incorporate the list of approved instance types in the CloudFormation template?
In the CloudFormation template, the developer should create a parameter with the list of approved EC2 instance types as AllowedValues. This way, users can select the instance type they want to use when launching the CloudFormation stack, but only from the approved list.
An ecommerce company is planning to migrate an on-premises Microsoft SQL Server database to the AWS Cloud. The company needs to migrate the database to SQL Server Always On availability groups. The cloud-based solution must be highly available.
Which solution will meet these requirements?
Why Option C is Correct:
SQL Server Always On availability groups require a shared storage solution. Amazon FSx for Windows File Server provides the shared storage necessary to implement Always On availability groups in a highly available configuration.
Why Other Options are Incorrect:
Option A: A single EBS volume cannot provide shared storage for Always On availability groups.
Option B: RDS does not support SQL Server Always On availability groups.
Option D: S3 is not a suitable storage tier for SQL Server database operations.
