Question 1

A company requires that all applications running on Amazon EC2 use 1AM roles to gam access to AWS services. A developer is modifying an application that currently relies on 1AM user access keys stored in environment variables to access Amazon DynamoDB tables using boto, the AWS SDK for Python.

The developer associated a role with the same permissions as the 1AM user to the EC2 instance, then deleted the 1AM user. When the application was restarted, the AWS

Access Denied Exception messages started appearing in the application logs. The developer was able to use their personal account on the server to run DynamoDB API commands using the AWS CLI.

What is the MOST likely cause of the exception?

Options:

A.

1AM policies might take a few minutes to propagate to resources.

B.

Disabled environment variable credentials are still being used by the application.

C.

The AWS SDK does not support credentials obtained using an instance role.

D.

The instance's security group does not allow access to http://169.254.169.254.

Question 2

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?

Options:

A.

Change the CloudFront Viewer protocol policy from "HTTP and HTTPS" to "HTTPS only."

B.

Add a Lambda function that uses the KMS key to decrypt the data fields before saving the data to the database.

C.

Enable encryption on the DB cluster by using the same KMS key that is used in CloudFront.

D.

Request and deploy a new SSL certificate to use with the CloudFront distribution.

Question 3

A developer compiles an AWS Lambda function and packages the result as a .zip file. The developer uses the Functions page on the Lambda console to attempt to upload the local packaged .zip file. When pushing the package to Lambda, the console returns the following error:

Which solutions can the developer use to publish the code? (Select TWO.)

Options:

A.

Upload the package to Amazon S3. Use the Functions page on the Lambda console to upload the package from the S3 location.

B.

Create an AWS Support ticket to increase the maximum package size.

C.

Use the update-function-code AWS CLI command. Pass the -publish parameter.

D.

Repackage the Lambda function as a Docker container image. Upload the image to Amazon Elastic Container Registry {Amazon ECR). Create a new Lambda function by using the Lambda console. Reference the image that is deployed to Amazon ECR.

E.

Sign the .zip file digitally. Create a new Lambda function by using the Lambda console. Update the configuration of the new Lambda function to include the Amazon Resource Name (ARN) of the code signing configuration.
