Certified Network Defense Architect (CNDA) Certification Exam Practice Test Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

  • Which of the following best defines a network defense architecture?
  • The process of configuring firewalls
  • The structured design of security controls to protect network
  • assets

  • The use of VPNs for remote access
  • A single point of defense for network security

Rationale: A network defense architecture integrates layered security

controls to protect data, applications, and infrastructure from attacks.

  • What is the main purpose of defense-in-depth?
  • To reduce system complexity
  • To provide multiple layers of security to mitigate risk 1 / 4
  • To simplify security management
  • To eliminate the need for network monitoring

Rationale: Defense-in-depth ensures that if one security layer fails,

others continue to provide protection.

  • In a Zero Trust Architecture, what is assumed about users and
  • devices?

  • All are trusted after authentication
  • None are trusted by default, even if inside the network
  • All are trusted inside the corporate perimeter
  • Trust is based on network location only

Rationale: Zero Trust assumes no inherent trust and continuously

verifies all connections.

  • What is the primary purpose of network segmentation?
  • Increase bandwidth
  • Simplify routing
  • Limit lateral movement of threats
  • Enhance wireless access

Rationale: Segmentation isolates network zones, reducing the spread

of breaches.

  • Which of the following is most effective in preventing ARP spoofing?

A. IDS

B. IPS

  • Dynamic ARP Inspection (DAI) 2 / 4
  • Port Mirroring

Rationale: Dynamic ARP Inspection validates ARP packets to prevent

spoofing.

  • Which device inspects traffic at Layer 7 of the OSI model?
  • Router
  • Switch
  • Next-Generation Firewall (NGFW)
  • Load Balancer

Rationale: NGFWs analyze application-level traffic, providing deeper

inspection and control.

  • Which protocol is primarily used for encrypting data in transit over
  • web traffic?

A. FTP

B. TLS

C. SMTP

D. SNMP

Rationale: TLS (Transport Layer Security) ensures confidentiality and

integrity of web communications.

  • What does an Intrusion Prevention System (IPS) do that an Intrusion
  • Detection System (IDS) does not?

  • Detects anomalies
  • Automatically blocks malicious activity
  • Sends alerts 3 / 4
  • Monitors network logs

Rationale: An IPS actively prevents threats by blocking or dropping

malicious packets.

  • What is a honeypot used for in a network defense strategy?
  • Encrypting data
  • Attracting attackers to study their behavior
  • Speeding up network traffic
  • Reducing bandwidth usage

Rationale: Honeypots lure attackers to controlled environments for

analysis.

  • What does SIEM stand for?
  • Security Internet Event Management
  • Secure Information Event Management
  • Security Information and Event Management
  • System Integrity and Event Monitoring

Rationale: SIEM combines security event monitoring and information

management for correlation and analysis.

  • Which of the following is an example of a network-based attack?
  • SQL Injection
  • DDoS
  • Password Brute-Force
  • Keylogging
  • / 4
