NEW QUESTION # 522
A developer creates a static website for their department The developer deploys the static assets for the website to an Amazon S3 bucket and serves the assets with Amazon CloudFront The developer uses origin access control (OAC) on the CloudFront distribution to access the S3 bucket The developer notices users can access the root URL and specific pages but cannot access directories without specifying a file name. For example, /products/index.html works, but /products returns an error The developer needs to enable accessing directories without specifying a file name without exposing the S3 bucket publicly.
Which solution will meet these requirements'?

A. Create a custom error response on the CloudFront distribution with the HTTP error code set to the HTTP 404 Not Found response code and the response page path to /index html Set the HTTP response code to the HTTP 200 OK response code
B. Create a CloudFront function that examines the request URL and appends index.html when directories are being accessed Add the function as a viewer request CloudFront function to the CloudFront distribution's behavior.
C. Update the Amazon S3 bucket settings and enable static website hosting. Specify index html as the Index document Update the S3 bucket policy to enable access. Update the CloudFront distribution's origin to use the S3 website endpoint
D. Update the CloudFront distribution's settings to index.html as the default root object is set

Answer: C

Explanation:
Problem: Directory access without file names fails.
S3 Static Website Hosting:
Configuring S3 as a static website enables automatic serving of index.html for directory requests.
Bucket policies ensure correct access permissions.
Updating the CloudFront origin simplifies routing.
Avoiding Public Exposure: The S3 website endpoint allows CloudFront to access content without making the bucket public.

NEW QUESTION # 523
When using the AWS Encryption SDK how does the developer keep track of the data encryption keys used to encrypt data?

A. The SDK stores the data encryption keys automaticity in Amazon S3.
B. The SDK encrypts the data encryption key and stores it (encrypted) as part of the resumed ophertext.
C. The data encryption key is stored m the user data for the EC2 instance.
D. The developer must manually keep Hack of the data encryption keys used for each data object.

Answer: B

Explanation:
Explanation
This solution will meet the requirements by using AWS Encryption SDK, which is a client-side encryption library that enables developers to encrypt and decrypt data using data encryption keys that are protected by AWS Key Management Service (AWS KMS). The SDK encrypts the data encryption key with a customer master key (CMK) that is managed by AWS KMS, and stores it (encrypted) as part of the returned ciphertext.
The developer does not need to keep track of the data encryption keys used to encrypt data, as they are stored with the encrypted data and can be retrieved and decrypted by using AWS KMS when needed. Option A is not optimal because it will require manual tracking of the data encryption keys used for each data object, which is error-prone and inefficient. Option C is not optimal because it will store the data encryption keys automatically in Amazon S3, which is unnecessary and insecure as Amazon S3 is not designed for storing encryption keys.
Option D is not optimal because it will store the data encryption key in the user data for the EC2 instance, which is also unnecessary and insecure as user data is not encrypted by default.
