,Q1. An enterprise is adopting a Zero Trust architecture. To enforce least privilege for inter-service
communications in a Kubernetes cluster, which of the following is the most effective approach?
A. Implement network policies that allow all traffic within the cluster by default.
B. Use a service mesh with mutual TLS and fine-grained access policies.
C. Configure a single API gateway to authenticate all external requests.
D. Deploy a VPN for all pod-to-pod communication.
Correct Answer: B. Use a service mesh with mutual TLS and fine-grained access policies.
Rationale: A service mesh (e.g., Istio) provides per-service authentication and authorization with mTLS, enabling
least privilege. Option A violates Zero Trust by allowing all internal traffic. Option C only addresses external
requests. Option D adds overhead and does not provide fine-grained control.
Why Wrong:
A - Allowing all internal traffic contradicts the 'never trust, always verify' principle.
C - An API gateway alone cannot enforce least privilege for inter-service communication.
D - VPNs are not designed for granular service-to-service policies in a dynamic environment.
Reference: NIST SP 800-207, Zero Trust Architecture; Istio documentation.
Q2. In the context of the SABSA security architecture framework, which of the following best describes the
purpose of the 'Business View' layer?
A. It defines the technical security controls and mechanisms.
B. It translates business requirements into security objectives and strategies.
C. It specifies the physical network topology and encryption standards.
D. It outlines the operational processes for incident response.
Correct Answer: B. It translates business requirements into security objectives and strategies.
Rationale: SABSA's Business View (Contextual Security Architecture) aligns security with business goals. Option A
is the Provider View; Option C is the Physical View; Option D is the Operational View.
Why Wrong:
A - Technical controls belong to the Provider View, not the Business View.
C - Network topology is part of the Physical View.
D - Incident response processes are part of the Operational View.
Reference: SABSA Methodology, SABSA Institute.
Q3. An organization implements a Just-in-Time (JIT) privileged access management solution. Which of the
following is a primary security benefit of this approach over traditional static privileged accounts?
A. It eliminates the need for multi-factor authentication.
B. It reduces the attack surface by granting privileges only when needed and for a limited duration.
C. It centralizes all credentials in a single vault without rotation.
D. It allows users to maintain persistent administrative sessions.
Correct Answer: B. It reduces the attack surface by granting privileges only when needed and for a limited
duration.
Rationale: JIT access minimizes standing privileges, reducing the window of opportunity for attackers. Option A is
false because MFA remains critical. Option C contradicts credential rotation best practices. Option D would
undermine the JIT principle.
Why Wrong:
A - JIT does not replace MFA; both are complementary.
C - JIT often includes automatic credential rotation, not static storage.
D - Persistent sessions violate the principle of ephemeral access.
Reference: NIST SP 800-207; CyberArk JIT Access documentation.

, Q4. During a security architecture review, a cloud-native application uses OAuth 2.0 for API authorization.
The application's resource server validates access tokens by calling the authorization server's introspection
endpoint on every request. Which security concern is most likely introduced by this design?
A. Increased latency and potential availability bottleneck.
B. The resource server cannot validate token expiration.
C. The authorization server becomes a single point of failure for authentication.
D. Tokens can be replayed indefinitely.
Correct Answer: A. Increased latency and potential availability bottleneck.
Rationale: Calling the introspection endpoint for every request adds network round-trip latency and may overload the
authorization server. Option B is incorrect because token expiration can be checked locally. Option C misstates the role
(authorization, not authentication). Option D is not directly caused by introspection.
Why Wrong:
B - Token expiration is embedded in the token and can be validated locally.
C - The authorization server handles authorization, not primary authentication.
D - Replay attacks are prevented by token binding or nonce, not by introspection frequency.
Reference: OAuth 2.0 RFC 6749; RFC 7662 Token Introspection.
Q5. A multinational corporation must comply with GDPR and the US CMMC framework. Which of the
following data classification strategies best supports both regulatory requirements?
A. Classify all data as 'confidential' to simplify compliance.
B. Implement a tiered classification scheme based on data sensitivity and regulatory categories.
C. Use only the CMMC classification levels for all data.
D. Apply a binary classification: 'personal data' vs. 'non-personal data'.
Correct Answer: B. Implement a tiered classification scheme based on data sensitivity and regulatory
categories.
Rationale: A tiered scheme that maps to both GDPR's personal data categories and CMMC's CUI levels is most
effective. Option A leads to overclassification and operational burden. Option C ignores GDPR-specific
requirements. Option D is too simplistic for CMMC.
Why Wrong:
A - Overclassification increases cost and reduces efficiency without improving compliance.
C - CMMC does not cover all GDPR requirements, such as consent and data portability.
D - Binary classification fails to address CMMC's different sensitivity levels for CUI.
Reference: GDPR Article 4; CMMC 2.0 Level 2 practices.
Q6. In a TOGAF-based security architecture project, which phase is most appropriate for defining security
architecture principles and conducting a risk assessment?
A. Phase A: Architecture Vision
B. Phase B: Business Architecture
C. Phase C: Information Systems Architectures
D. Phase D: Technology Architecture
Correct Answer: A. Phase A: Architecture Vision
Rationale: Phase A establishes the architecture vision, including principles, scope, and high-level risks. Phase B
focuses on business processes, Phase C on data and application architecture, and Phase D on technology
infrastructure. Risk assessment at Phase A sets the foundation.
Why Wrong:
B - Phase B details business architecture but does not define overarching principles.
C - Phase C addresses specific data and application architectures, not initial risk assessment.
D - Phase D deals with technology choices, not enterprise-level risk assessment.
