CNX-001 Exam Dumps - CompTIA CloudNetX Exam

Comprehensive and Detailed Explanation From Exact Extract:

Traffic mirroring allows a copy of network traffic — including headers and payloads — to be sent to an analysis tool or appliance for deep packet inspection. This is essential for security analysis, network troubleshooting, and performance diagnostics in cloud environments.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Packet Capture and Network Flow Monitoring”:

“Traffic mirroring enables the capture of full packet data, including payloads, for forensic or performance analysis within cloud networks.”

Other options:

A. Application monitoring focuses on app-level metrics, not packet inspection.

B. Syslog is log-based, not for inspecting packets.

D. Network flows (e.g., NetFlow, VPC flow logs) provide metadata (source, destination, size) but not full packet content.

Comprehensive and Detailed Explanation From Exact Extract:

The Hub-and-Spoke topology is ideal for SD-WAN environments where traffic from branch offices or cloud workloads must route through a central location (the hub) for inspection, monitoring, or security enforcement. This structure centralizes egress and allows for redundant spoke paths via the hub. It also simplifies control and enforces compliance policies.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “SD-WAN Topologies and Cloud Egress Strategies”:

“In a hub-and-spoke topology, spokes (remote offices or cloud nodes) connect through a central hub, allowing for centralized egress, traffic inspection, and simplified routing.”

Other options:

A. Point-to-point doesn’t scale and lacks centralized control.

C. Star topology is similar to hub-and-spoke but is more rigid and less suited for SD-WAN scalability.

D. Partial mesh allows direct spoke-to-spoke communication, bypassing centralized inspection.

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:

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:

A SIEM (Security Information and Event Management) system aggregates logs from various sources, including cloud environments, and provides real-time analytics, threat detection, and automated alerting. It integrates with cloud workloads via agents or APIs and enables centralized visibility and response capabilities.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Security Monitoring and Event Correlation”:

“SIEM solutions consolidate logs from multiple environments, including cloud and on-premises, providing automated detection, alerting, and correlation of security events.”

“A SIEM supports compliance and improves incident response through real-time monitoring.”

Other options:

A. IDS/IPS are used for intrusion detection/prevention but do not provide log consolidation or alert correlation.

C. Data lakes store large volumes of data but lack real-time alerting without additional tools.

D. Syslog is a protocol for log transport, not a detection and alerting mechanism.

Comprehensive and Detailed Explanation From Exact Extract:

Replacing reserved IPs with dynamic ones can lead to IP reuse issues. Dynamic public IPs can be reallocated to other customers once released. If DNS entries or firewall rules still refer to the original IP, this can lead to data leakage or incorrect routing. Also, some services (e.g., NSGs, load balancers) may require persistent IPs.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Public IP Management in Cloud Environments”:

“Dynamic public IPs are subject to reuse after release. Services that rely on IP persistence, such as security groups or load balancers, may encounter unexpected behavior or security risks if replaced with dynamically assigned IPs.”

Other options:

A. Asymmetric routing involves traffic leaving and returning via different paths.

B. IP spoofing is a malicious attack, not related to address reassignment.

C. IP exhaustion relates to resource limits, not dynamic reuse.

 

Comprehensive and Detailed Explanation From Exact Extract:

A mesh topology allows every site to connect directly to every other site, enabling the shortest and lowest-latency path between locations. This is ideal for SD-WAN deployments that must minimize latency for inter-site communication globally. In contrast, hub-and-spoke models force all traffic through a central hub, increasing latency.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “WAN Technologies and Topologies”:

“Mesh topologies offer direct connectivity between all participating sites, reducing latency and avoiding single points of failure. They are optimal for SD-WAN deployments requiring performance and resilience.”

Other options:

A. Star topology routes all traffic through a central node, introducing latency.

B. Spine-and-leaf is used in data center architectures, not global WANs.

D. Hub-and-spoke centralizes routing and increases latency between remote sites.

A full-mesh SD-WAN topology allows each site to establish direct overlays with every other site, minimizing the number of hops and avoiding backhauling through a central hub, thereby delivering the lowest latency paths between Asia, Europe, and the US.

Comprehensive and Detailed Explanation From Exact Extract:

Geofencing allows enforcement of access policies based on the geographic location of the user's IP address. To comply with GDPR and control access based on user region, geofencing should be implemented to restrict or permit access to resources hosted in specific regions like Europe.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Data Sovereignty and Regional Access Control”:

“Geofencing enables organizations to restrict access to data or services based on geographic IP address, aiding in GDPR and other compliance frameworks.”

Other options:

A. SASE is a broader framework, not a direct access control mechanism.

B. NSGs operate at subnet/NIC level and do not interpret geolocation.

C. CDNs cache data globally but don’t control access by region directly.
