CompTIA Updated CNX-001 Exam Questions and Answers by frida

Comprehensive and Detailed Explanation From Exact Extract:

Quality of Service (QoS) ensures that latency-sensitive traffic like videoconferencing is prioritized over bandwidth-heavy but delay-tolerant tasks like report generation. Implementing QoS on network switches allows the network to differentiate traffic types and ensure sufficient bandwidth for critical applications during congestion.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Traffic Prioritization and QoS”:

“QoS enables classification and prioritization of network traffic to ensure performance of mission-critical or real-time applications such as voice and video.”

Other options:

A. Scheduling tasks outside business hours is not scalable or reliable.

B. Load balancing applies to servers, not prioritization of LAN traffic.

D. Buying higher-end switches is costly and may not resolve contention under load.

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.

Comprehensive and Detailed Explanation From Exact Extract:

“Identity as the perimeter” is a core principle of Zero Trust Architecture (ZTA). Rather than relying on traditional network-based perimeters, access is granted based on user identity and device posture. This is essential for remote users accessing cloud workloads, ensuring secure authentication regardless of physical location.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Zero Trust and Identity-Centric Security”:

“Zero Trust shifts the trust boundary from the network to the user and device identity. ‘Identity as the perimeter’ ensures only verified users and devices are granted access to resources.”

Other options:

A. Secure service edge (SSE) is a broad cloud security model, but not a specific ZTA principle.

B. CASBs monitor cloud app usage, not core access authentication.

C. Principle of least privilege is a supporting concept, but not the primary perimeter defense mechanism.

Comprehensive and Detailed Explanation From Exact Extract:

Using an active-active deployment across two regions with at least two Availability Zones (AZs) each provides the highest level of fault tolerance and geographic redundancy. This ensures continuity even if an entire region or multiple zones become unavailable. In regulated sectors such as healthcare, this meets strict availability and disaster recovery requirements.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “High Availability and Multi-Region Design”:

“Active-active configurations across multiple regions and availability zones maximize uptime and ensure failover in the event of localized or regional failures.”

Other options:

B. Active-passive introduces delays in failover.

C. Active-active in one region offers no geographic redundancy.

D. Active-passive in two regions is slower and less efficient during failover.
