CNX-001 CompTIA CloudNetX Exam Free Practice Exam Questions (2025 Updated)

Comprehensive and Detailed Explanation From Exact Extract:

Network Access Control (NAC) evaluates the posture of a device before allowing access to the network. It can enforce security policies, authenticate users and devices, and isolate or remediate non-compliant devices. NAC is widely used in enterprise environments to secure access at the network edge, such as in guest or public areas.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Access Control and Posture Assessment”:

“NAC provides device authentication, security posture validation, and can enforce automated remediation or quarantine actions based on policy compliance.”

Other options:

A. IPS detects and prevents known threats but does not perform access control or posture checks.

B. Microsegmentation isolates workloads but lacks posture checks and auto-remediation.

Comprehensive and Detailed Explanation From Exact Extract:

Reference architectures are pre-defined templates or blueprints provided by vendors, standardsbodies, or industry alliances (e.g., NIST, CIS, vendor frameworks) that define recommended practices for secure and reliable infrastructure design. They help ensure alignment with compliance, security controls, and industry-recognized configurations.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Architecture Standards and Security Best Practices”:

“Reference architectures guide the implementation of secure, scalable, and compliant infrastructure. They embody industry best practices and reduce misconfiguration risks in cloud and hybrid environments.”

Other options:

B. Licensing agreements pertain to software usage rights, not security alignment.

C. SLAs define service expectations, not design standards.

D. MOUs are informal agreements between parties, not technical or security frameworks.

Comprehensive and Detailed Explanation From Exact Extract:

Since the subnet and IPs were changed recently, and users are accessing the database through a web application, the likely issue is that DNS records have not been updated to reflect the new IP addresses. If DNS is pointing to old IPs, users will fail to reach the services even if they are up and reachable on the new subnet.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “DNS and Network Configuration Troubleshooting”:

“DNS misconfiguration is a common issue following IP address changes. If DNS entries are not updated accordingly, clients will attempt to reach services at outdated IPs.”

Other options:

A. No indication of web server misconfiguration is provided.

B. Firewall issues would affect all users, not just one.

D. The web server has a valid IP in the subnet range; no misconfiguration is indicated.

Comprehensive and Detailed Explanation From Exact Extract:

To verify that the certificate and the private key match, one can extract the modulus from both files and compare their hash values. The correct syntax involves using openssl x509 to extract the modulus from the certificate, and openssl rsa to extract the modulus from the private key, followed by an MD5 hash to ensure they match.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “TLS/SSL Certificate Validation and Troubleshooting”:

“To verify that the private key and certificate match, compare the modulus values. A mismatch results in failed TLS handshakes.”

Other options:

A & C: Incorrect syntax (openssl-list and openssl-rsa are not valid commands).

B: The commands shown are used to verify CSRs, not matching keys.
