NEW QUESTION # 346
A company has an Amazon S3 bucket that contains sensitive data. The data must be encrypted in transit and at rest. The company encrypts the data in the S3 bucket by using an AWS Key Management Service (AWS KMS) key. A developer needs to grant several other AWS accounts the permission to use the S3 GetObject operation to retrieve the data from the S3 bucket.
How can the developer enforce that all requests to retrieve the data provide encryption in transit?

A. Define a resource-based policy on the S3 bucket to deny access when a request meets the condition
"aws:SecureTransport": "false".
B. Define a resource-based policy on the KMS key to deny access when a request meets the condition of
"aws:SecureTransport": "false".
C. Define a role-based policy on the other accounts' roles to deny access when a request meets the condition of "aws:SecureTransport": "false".
D. Define a resource-based policy on the S3 bucket to allow access when a request meets the condition
"aws:SecureTransport": "false".

Answer: A

Explanation:
Amazon S3 supports resource-based policies, which are JSON documents that specify the permissions for accessing S3 resources. A resource-based policy can be used to enforce encryption in transit by denying access to requests that do not use HTTPS. The condition key aws:SecureTransport can be used to check if the request was sent using SSL. If the value of this key is false, the request is denied; otherwise, the request is allowed. Reference: How do I use an S3 bucket policy to require requests to use Secure Socket Layer (SSL)?

NEW QUESTION # 347
A company has built an AWS Lambda function to convert large image files into output files that can be used in a third-party viewer application The company recently added a new module to the function to improve the output of the generated files However, the new module has increased the bundle size and has increased the time that is needed to deploy changes to the function code.
How can a developer increase the speed of the Lambda function deployment?

A. Use Lambda layers to package and load dependencies.
B. Use AWS CodeDeploy to deploy the function code
C. Use Amazon S3 to host the function dependencies
D. Increase the memory size of the function.

Answer: A

Explanation:
* Problem: Large bundle size increases Lambda deployment time.
* Lambda Layers: Layers let you package dependencies separately from your function code. This optimizes the deployment package, making updates faster.
* Modularization: Breaking down dependencies into layers improves code organization and reusability.

NEW QUESTION # 348
An organization has created 10 IAM users. The organization wants those users to work independently and access AWS. Which of the below mentioned options is not a possible solution?

A. Enable MFA for each IAM user and assign them the virtual MFA device to access the console
B. Create the X.509 certificate for each user and provide them access to AWS CLI
C. Provide each user with the IAM login and password for the AWS console
D. Create the access key and secret access key for each user and provide access to AWS using the console

Answer: D

Explanation:
If an organization has created the IAM users, the users can access AWS services either with an IAM specific login/password or console. The organization can generate the IAM X.509 certificates to access AWS with CLI. The organization can also enable MFA for each IAM user, which allows an added security for each IAM user. If the organization has created the access key and secret key than the user cannot access the console using those keys. Access key and secret access key are useful for CLI or Webservices.
