NCA-AIIO Practice Questions

Master Security and Compliance

Security Foundation: Effective security requires understanding infrastructure architecture and data management. Complete our AI Infrastructure Fundamentals and Hardware and System Architecture practice questions first, then review our Complete NCA-AIIO Study Guide.

Master Security and Compliance with practice questions covering access control, data protection, network security, and regulatory compliance for AI infrastructure environments.

Data Security Connection

Security implementation requires understanding data flow and storage architectures. Review our Data Management and Storage practice questions to understand the data protection concepts that underpin effective security strategies.

Question 1: Role-Based Access Control

In a multi-tenant AI infrastructure, which access control strategy provides the best balance of security and operational flexibility?

A) Single shared administrator account

B) Role-based access control (RBAC) with least privilege principle

C) No access controls

D) Password-only authentication

Show Answer & Explanation

Correct Answer: B

Explanation: RBAC with least privilege ensures users have only the minimum access needed for their role, reducing security risks while maintaining operational efficiency. This access control foundation is essential for the infrastructure concepts covered in our AI Infrastructure Fundamentals practice questions.

Question 2: Data Encryption Standards

For AI training datasets containing sensitive information, which encryption approach provides comprehensive data protection?

A) Encryption at rest only

B) Encryption in transit only

C) End-to-end encryption (at rest, in transit, and in use)

D) No encryption needed for internal data

Show Answer & Explanation

Correct Answer: C

Explanation: End-to-end encryption protects data in all states - storage (at rest), transmission (in transit), and processing (in use) - providing comprehensive security coverage. This encryption strategy connects to the data management concepts covered in our Data Management and Storage practice questions.

Question 3: Network Security Segmentation

In an AI data center environment, which network security approach provides the best protection against lateral movement attacks?

A) Single flat network with perimeter firewall

B) Micro-segmentation with zero-trust architecture

C) VPN access only

D) Physical air-gapping only

Show Answer & Explanation

Correct Answer: B

Explanation: Micro-segmentation with zero-trust principles creates security boundaries around each workload, preventing unauthorized lateral movement even if one segment is compromised. This security architecture builds on the hardware infrastructure concepts from our Hardware and System Architecture practice questions.

Question 4: Compliance Monitoring

For maintaining GDPR compliance in AI systems processing personal data, which monitoring approach is most effective?

A) Annual compliance reviews only

B) Continuous monitoring with automated compliance checks

C) Manual quarterly audits

D) Self-certification without monitoring

Show Answer & Explanation

Correct Answer: B

Explanation: Continuous monitoring with automated compliance checks enables real-time detection of policy violations and ensures ongoing adherence to regulations. This monitoring capability leverages the performance tracking concepts from our Performance Optimization and Monitoring practice questions.

Question 5: Incident Response Security

During a suspected security breach in an AI training environment, what is the first security-focused action to take?

A) Continue normal operations

B) Isolate affected systems and preserve evidence

C) Delete all logs to prevent data exposure

D) Restart all systems immediately

Show Answer & Explanation

Correct Answer: B

Explanation: Isolating affected systems prevents further damage while preserving evidence for forensic analysis. This incident response protocol aligns with the troubleshooting procedures covered in our Troubleshooting and Maintenance practice questions.
