CNX-001 Exam Dumps : CompTIA CloudNetX Exam

Comprehensive and Detailed Explanation From Exact Extract:

Video surveillance (A) provides continuous monitoring and allows for real-time, remote visibility of secure locations, such as computer rooms. When integrated with analytics, video surveillance systems can detect movement after hours or unauthorized access and generate immediate alerts. These systems also maintain video logs that can be audited later.

NFC access cards (B) allow controlled access to physical areas, generating time-stamped logs for each entry attempt. When connected to an access control system, these cards can trigger alerts for unauthorized access attempts, such as the use of expired credentials or access during restricted hours.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — Security Controls and Physical Security Section:

“Security access systems using NFC or smart cards allow traceability of personnel entry through electronic logs, while surveillance systems provide visibility and support forensic investigations.”

“Video surveillance allows real-time monitoring of physical environments and helps detect unauthorized presence or access in sensitive locations.”

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:

nmap -A performs aggressive scanning, which includes OS detection, version detection, script scanning, and traceroute — exactly what is required in this case. It's the most effective and commonly used tool for comprehensive network reconnaissance prior to security testing.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Security Scanning and Reconnaissance Tools”:

“Nmap supports comprehensive scanning options, including OS fingerprinting, service version detection, and port scanning, enabling detailed pre-penetration testing assessments.”

Other options:

A. tcpdump is for packet capture, not scanning.

C. nc (netcat) is a port scanning tool, but it lacks OS/app detection.

D. hping3 is a packet generator, not suitable for full-service scanning.
