CompTIA CNX-001 Dumps Questions Answers

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:

Jitter refers to the variation in packet delay during transmission. In the ping output shown, the response times fluctuate significantly (11ms, 672ms, 849ms, 34ms), indicating inconsistent network performance. Such variation leads to a poor experience in real-time applications likevideo calls. High jitter causes packets to arrive out of order, resulting in stuttering or choppy audio/video.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Troubleshooting Real-Time Network Services”:

“Jitter is the deviation in packet arrival times and directly affects real-time communications such as VoIP and video conferencing. Consistent latency is tolerable; inconsistent latency (jitter) is disruptive.”

Other options:

A. Throughput refers to bandwidth and would cause consistent slowness.

C. Latency alone, if stable, is acceptable; it's the inconsistency here that causes issues.

D. Loss would be indicated by missing packets; the ping results show replies to all packets.

Comprehensive and Detailed Explanation From Exact Extract:

Geofencing is a network access control method that enforces restrictions based on location data. In this scenario, the organization requires access to be permitted only when users are on premises (i.e., within a specific physical location). Geofencing can be implemented using source IP ranges or GPS-based location data to define boundaries (fences). This allows access to certain applications or services only when the user is inside a designated network or area.

MFA (Option A) provides identity assurance but does not enforce physical location-based restrictions.

UEBA (Option C) provides behavioral analytics but is not used for real-time access control.

PKI (Option D) provides identity validation through certificates but is not location-aware.

Relevant Extract from CompTIA CloudNetX CNX-001 Official Study Guide:

“Geofencing allows organizations to define physical or logical boundaries that restrict or allow access based on user location. Policies can be configured to allow access only when users are on a trusted campus or corporate network, denying requests originating from outside the geofenced area.”
