| Question.41 According to the AWS shared responsibility model, what responsibility does a customer have when using Amazon RDS to host a database? (A) Manage connections to the database (B) Install Microsoft SQL Server (C) Design encryption-at-rest strategies (D) Apply minor database patches |

Answer is (A) Manage connections to the database
Amazon RDS encrypts your databases using keys you manage with the AWS Key Management Service (KMS). On a database instance running with Amazon RDS encryption, data stored at rest in the underlying storage is encrypted, as are its automated backups, read replicas, and snapshots. Amazon RDS encryption uses the industry standard AES-256 encryption algorithm to encrypt your data on the server that hosts your Amazon RDS instance.
Designing an encryption strategy means building the strategy from scratch (including choosing the best-fit encryption algorithm for that strategy), as mentioned before, selecting a one is different from design/create a new one.

| Question.44 A company wants to eliminate the need to guess infrastructure capacity before deployments. The company also wants to spend its budget on cloud resources only as the company uses the resources. Which advantage of the AWS Cloud matches the company’s requirements? (A) Reliability (B) Global reach (C) Economies of scale (D) Pay-as-you-go pricing |

Answer is (D) Pay-as-you-go pricing
Trade fixed expense for variable expense – Instead of having to invest heavily in data centers and servers before you know how you’re going to use them, you can pay only when you consume computing resources, and pay only for how much you consume.
