20+ practice questions focused on Design Secure Architectures — one of the most tested topics on the SAA-C03 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Design Secure Architectures PracticeA platform team lets project administrators create IAM roles for workloads in their own AWS accounts, but every role must stay inside a fixed security baseline. The organization also wants to block all member accounts from using AWS Regions outside us-east-1 and us-west-2. Which three controls should be used? Select three.
Explanation: Attaching a permissions boundary to each role created through delegation ensures that even if a project administrator grants excessive permissions, the effective permissions are limited by the boundary. This enforces the fixed security baseline without preventing administrators from creating roles within those constraints.
A batch job runs on EC2 instances in isolated private subnets with no NAT Gateway. The job uses STS AssumeRole to access an operations account and then retrieves a secret from AWS Secrets Manager. After a network hardening change, both calls fail. Which two interface VPC endpoints should be created? Select two.
Explanation: The batch job uses STS AssumeRole, which requires calling the AWS STS API. Without a NAT Gateway or Internet Gateway, private subnets cannot reach public endpoints. An interface VPC endpoint for STS allows the EC2 instances to call AssumeRole privately using AWS PrivateLink, without needing internet access.
A CI system runs on EC2 instances in private subnets and uploads build artifacts to an S3 bucket. The security team wants to eliminate NAT Gateway costs, force all uploads to use TLS, and require SSE-KMS with an approved customer managed key. Which three changes should be made? Select three.
Explanation: Creating an S3 gateway VPC endpoint allows EC2 instances in private subnets to access S3 without traversing the internet, eliminating the need for a NAT Gateway and its associated costs. The endpoint uses AWS’s internal network, and associating it with the private subnets' route tables ensures traffic to S3 is routed through the endpoint.
Security responders suspect exfiltration from an Amazon S3 bucket that stores sensitive reports encrypted with a customer managed KMS key. They need to identify which IAM principal downloaded each object and whether any principals called KMS Decrypt on the key during the same time window. Which two detective controls should be enabled? Select two.
Explanation: Enabling CloudTrail data events for the S3 bucket captures detailed logs of object-level operations, including GetObject (download) requests. This allows you to identify which IAM principal downloaded each object, including the source IP, user agent, and request time. Without data events, CloudTrail only logs management-level actions (e.g., bucket creation) and misses object-level access.
Your company requires that all requests to an S3 bucket use HTTPS and that all objects uploaded to the bucket are encrypted at rest. You manage the S3 bucket policy and want enforcement that does not rely on application code compliance. Which bucket policy change best enforces both requirements?
Explanation: It uses a Deny statement with the `aws:SecureTransport` condition to block any request that does not use HTTPS, enforcing encryption in transit. It also adds a Deny statement for `s3:PutObject` when the request does not include the `x-amz-server-side-encryption` header set to `AES256`, ensuring that all uploaded objects are encrypted at rest with SSE-S3. This policy-based enforcement works regardless of application code, meeting the requirement for non-reliance on client-side compliance.
