[2025 Practice Exam]AWS Certified Solution Architect SAA-C03

The AWS Certified Solutions Architect - Associate (SAA-C03)  practice exam is intended for individuals who are planning to take the exam and get certified.  The Practice exam contains 325 unique high-quality real exam like test questions+detailed explanations and validates a individuals’s ability to complete the following tasks:

1. The exam validates a candidate’s ability to design solutions based on the AWS Well-Architected Framework.

2. Design solutions that incorporate AWS services to meet current business requirements and future projected needs

3. Design architectures that are secure, resilient, high-performing, and cost optimized

4. Review existing solutions and determine improvements

Sample Question

A healthcare company must encrypt RDS data at rest but also manage and rotate its own keys. Which configuration meets this requirement with minimal operational effort?

Option 1 - Encrypt the EBS volume attached to the RDS host instance

Option 2 - Enable RDS encryption using a customer‑managed KMS key (CMK)

Option 3 - Store data unencrypted in RDS and rely on application‑level AES encryption only

Option 4 - Use Transparent Data Encryption (TDE) manually inside the database

Correct Answer - 2

Explanation 1 - RDS is managed; you cannot access underlying EBS volumes

Explanation 2 - RDS handles the encryption while the customer controls the CMK, rotation schedule, and grants

Explanation 3 - Adds complexity and doesn’t encrypt automated backups, snapshots, or replicas

Explanation 4 - Requires engine‑specific setup; still better to use built‑in RDS + KMS integration

Overall explanation

When you choose *Enable encryption* on Amazon RDS and reference a **customer‑managed** CMK, AWS transparently encrypts the entire storage layer—data files, redo logs, temp space, and automatic backups—while leaving full key ownership to you. You define key policies, enable 365‑day rotation, create cross‑account grants, and can revoke access instantly if required by a breach scenario. Because encryption/decryption is performed in the storage engine, no application code changes are necessary and in‑flight performance overhead is negligible.
