,Q1. A financial services firm is migrating its on-premises data center to a public cloud provider. The
firm must comply with PCI DSS and maintain a clear separation of duties between security
administration and network operations. Which cloud architecture model best meets these
requirements while minimizing operational overhead?
A. Single-tenant dedicated hosting with a VPN back to the on-premises network
B. Multi-tenant IaaS with role-based access control and network segmentation via VPCs
C. Hybrid cloud with a dedicated management plane and automated compliance monitoring
D. Community cloud with shared security controls among financial institutions
Correct Answer: C. Hybrid cloud with a dedicated management plane and automated compliance
monitoring
Rationale: A hybrid cloud with a dedicated management plane allows clear separation of duties by
isolating administrative functions from operational ones, while automated compliance monitoring ensures
continuous PCI DSS adherence without manual overhead. Single-tenant hosting (A) lacks automated
compliance tools and may increase cost. Multi-tenant IaaS (B) can support RBAC but does not inherently
enforce separation of duties. Community cloud (D) may not meet specific PCI DSS requirements for
financial services.
Why Wrong:
A - Single-tenant hosting lacks automated compliance monitoring and does not inherently enforce
separation of duties.
B - Multi-tenant IaaS with RBAC and VPCs can support security but does not guarantee separation
of duties without additional management plane isolation.
D - Community cloud may not align with the firm's specific PCI DSS obligations and could
introduce compliance gaps.

Q2. An organization deploys a web application on a public cloud using a serverless architecture with
AWS Lambda and API Gateway. The security team discovers that an attacker is able to invoke the
Lambda function directly by guessing the function's ARN, bypassing API Gateway's authentication
and rate limiting. Which of the following is the most effective remediation?
A. Implement a resource-based policy on the Lambda function that denies invocation from any
principal except API Gateway
B. Use a VPC endpoint for Lambda and restrict access to the function from within the VPC only
C. Enable AWS WAF on the API Gateway to filter malicious requests
D. Rotate the Lambda function's execution role credentials and enforce MFA on all IAM users
Correct Answer: A. Implement a resource-based policy on the Lambda function that denies
invocation from any principal except API Gateway
Rationale: A resource-based policy on the Lambda function that explicitly denies invocation from any
principal except API Gateway directly prevents direct invocation by unauthorized entities. VPC endpoints
(B) do not block external access if the function is publicly exposed. AWS WAF (C) only protects API
Gateway, not the Lambda function itself. Rotating credentials (D) does not address the direct invocation
vulnerability.
Why Wrong:
B - Restricting to VPC does not prevent direct invocation if the function is still publicly accessible
via the internet.
C - AWS WAF operates at the API Gateway level and cannot block direct Lambda invocation
requests.

, D - Credential rotation and MFA do not mitigate the risk of unauthorized direct function invocation.
