Question #: 349
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company stores confidential data in an Amazon Aurora PostgreSQL database in the ap-southeast-3 Region. The database is encrypted with an AWS Key Management Service (AWS KMS) customer managed key. The company was recently acquired and must securely share a backup of the database with the acquiring company’s AWS account in ap-southeast-3.

What should a solutions architect do to meet these requirements?

A. Create a database snapshot. Copy the snapshot to a new unencrypted snapshot. Share the new snapshot with the acquiring company’s AWS account.
B. Create a database snapshot. Add the acquiring company’s AWS account to the KMS key policy. Share the snapshot with the acquiring company’s AWS account.
C. Create a database snapshot that uses a different AWS managed KMS key. Add the acquiring company’s AWS account to the KMS key alias. Share the snapshot with the acquiring company's AWS account.
D. Create a database snapshot. Download the database snapshot. Upload the database snapshot to an Amazon S3 bucket. Update the S3 bucket policy to allow access from the acquiring company’s AWS account.

Selected Answer: B

A. - "So let me get this straight, with the current company the data is protected and encrypted. However, for the acquiring company the data is unencrypted? How is that fair?" C - Wouldn't recommended this option because using a different AWS managed KMS key will not allow the acquiring company's AWS account to access the encrypted data. D. - Don't risk it for a biscuit and get fired!!!! - by downloading the database snapshot and uploading it to an Amazon S3 bucket. This will increase the risk of data leakage or loss of confidentiality during the transfer process. B - CORRECT

I believe the reason why option C is not the correct answer is that adding the acquiring company's AWS account to the KMS key alias doesn't directly control access to the encrypted data. KMS key aliases are simply alternative names for KMS keys and do not affect access control. Access to encrypted data is goverened by KMS key policies, which define who can use the key for encryption and decryption.

Selected Answer: B

To securely share a backup of the database with the acquiring company's AWS account in the same Region, a solutions architect should create a database snapshot, add the acquiring company's AWS account to the AWS KMS key policy, and share the snapshot with the acquiring company's AWS account. Option A, creating an unencrypted snapshot, is not recommended as it will compromise the confidentiality of the data. Option C, creating a snapshot that uses a different AWS managed KMS key, does not provide any additional security and will unnecessarily complicate the solution. Option D, downloading the database snapshot and uploading it to an S3 bucket, is not secure as it can expose the data during transit. Therefore, the correct option is B: Create a database snapshot. Add the acquiring company's AWS account to the KMS key policy. Share the snapshot with the acquiring company's AWS account.

Option B is the correct answer. Option A is not recommended because copying the snapshot to a new unencrypted snapshot will compromise the confidentiality of the data. Option C is not recommended because using a different AWS managed KMS key will not allow the acquiring company's AWS account to access the encrypted data. Option D is not recommended because downloading the database snapshot and uploading it to an Amazon S3 bucket will increase the risk of data leakage or loss of confidentiality during the transfer process.

It is C, you have to create a new key. Read below You can't share a snapshot that's encrypted with the default AWS KMS key. You must create a custom AWS KMS key instead. To share an encrypted Aurora DB cluster snapshot: Create a custom AWS KMS key. Add the target account to the custom AWS KMS key. Create a copy of the DB cluster snapshot using the custom AWS KMS key. Then, share the newly copied snapshot with the target account. Copy the shared DB cluster snapshot from the target account https://aws.amazon.com/premiumsupport/knowledge-center/aurora-share-encrypted-snapshot/

I also thought straight away that it could be C, however, the questions mentions that the database is encrypted with an AWS KMS custom key already. So maybe the letter B could be right, since it already has a custom key, not the default KMS Key. What do you think?

It is B. There's no need to create another custom AWS KMS key. https://aws.amazon.com/premiumsupport/knowledge-center/aurora-share-encrypted-snapshot/ Give target account access to the custom AWS KMS key within the source account 1. Log in to the source account, and go to the AWS KMS console in the same Region as the DB cluster snapshot. 2. Select Customer-managed keys from the navigation pane. 3. Select your custom AWS KMS key (ALREADY CREATED) 4. From the Other AWS accounts section, select Add another AWS account, and then enter the AWS account number of your target account. Then: Copy and share the DB cluster snapshot

Yes, as per the given information "The database is encrypted with an AWS Key Management Service (AWS KMS) customer managed key", it may not be the default AWS KMS key.
