Architecting on AWS Certification Codes & Standards Compliance 4 — Questions and Answers
Question 1: An architect needs to automate evidence collection for PCI DSS, HIPAA, and NIST 800-53 frameworks continuously. Which AWS service is purpose-built for this?
- AWS Config
- AWS Audit Manager (Correct answer)
- AWS Security Hub
- Amazon Inspector
Correct answer: AWS Audit Manager
AWS Audit Manager continuously collects evidence from AWS services, maps it to compliance frameworks like PCI DSS and HIPAA, and generates audit-ready reports.
Question 2: A company uses AWS Organizations and wants to prevent any member account from disabling CloudTrail. Which is the most scalable enforcement mechanism?
- IAM permission boundaries on each account's root user
- An SCP denying cloudtrail:StopLogging and cloudtrail:DeleteTrail across the organization (Correct answer)
- AWS Config rule in each account
- CloudWatch Events alarm per account
Correct answer: An SCP denying cloudtrail:StopLogging and cloudtrail:DeleteTrail across the organization
An SCP applied at the organization root or OU level preventively blocks cloudtrail:StopLogging and cloudtrail:DeleteTrail for all member accounts, regardless of IAM policies.
Question 3: Which encryption standard must AWS KMS CMKs use to comply with FIPS 140-2 Level 2, as required by many US government frameworks?
- 3DES with 112-bit keys
- AES-256 with validated HSMs (Correct answer)
- RSA-1024
- Blowfish-128
Correct answer: AES-256 with validated HSMs
AWS KMS uses AES-256 on FIPS 140-2 Level 2 validated hardware security modules (HSMs), meeting federal cryptographic standards.
Question 4: A retail company processing credit cards must segment its CDE from other systems per PCI DSS Requirement 1. Which AWS networking approach provides the strongest isolation?
- Using separate security groups within the same VPC
- Placing CDE resources in a dedicated AWS account with its own VPC and no VPC peering to non-CDE (Correct answer)
- Enabling VPC Flow Logs on the CDE subnet
- Using Network ACLs with strict inbound rules
Correct answer: Placing CDE resources in a dedicated AWS account with its own VPC and no VPC peering to non-CDE
A dedicated AWS account with its own VPC provides account-level blast-radius containment and prevents any inadvertent network paths from non-CDE environments.
Question 5: GDPR Article 17 grants users the 'right to erasure.' Which S3 capability most directly supports complying with this requirement?
- S3 Lifecycle policies to transition objects to Glacier
- S3 Object Lock in Compliance mode
- S3 batch operations to delete specific objects on demand (Correct answer)
- S3 Intelligent-Tiering
Correct answer: S3 batch operations to delete specific objects on demand
S3 Batch Operations can target and permanently delete specific objects (e.g., a user's data) across large buckets, enabling compliance with GDPR right-to-erasure requests.
Question 6: An architect must ensure data in transit between on-premises systems and AWS meets NIST 800-52 TLS requirements. What is the recommended approach?
- Use HTTP with IP whitelisting
- Configure AWS services to use TLS 1.2 or higher and disable older protocol versions (Correct answer)
- Use AWS Direct Connect without encryption
- Enable VPC Flow Logs
Correct answer: Configure AWS services to use TLS 1.2 or higher and disable older protocol versions
NIST SP 800-52 mandates TLS 1.2 minimum; AWS services support enforcing minimum TLS versions via security policies on load balancers, API Gateway, and CloudFront.
Question 7: Which AWS feature enables an organization to define a minimum baseline of security controls that cannot be overridden by member accounts, supporting CIS Benchmark compliance?
- IAM Access Analyzer
- AWS Control Tower Guardrails (mandatory controls) (Correct answer)
- Amazon Macie
- AWS Shield Standard
Correct answer: AWS Control Tower Guardrails (mandatory controls)
AWS Control Tower mandatory guardrails enforce non-negotiable security baselines (e.g., CloudTrail enabled, S3 public access blocked) across all enrolled accounts, supporting CIS Benchmark requirements.
An architect needs to automate evidence collection for PCI DSS, HIPAA, and NIST 800-53 frameworks continuously.
