Pass the CompTIA CloudNetX CNX-001 Questions and answers with CertsForce

Comprehensive and Detailed Explanation From Exact Extract:

When SSL/HTTPS inspection is enabled on a firewall, it intercepts and decrypts HTTPS traffic. This requires the firewall to present its own trusted certificate to the client device. If that certificate is expired, the client browser will display a certificate error and block access to the application. This is a common misconfiguration that breaks HTTPS communication.

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

“SSL inspection appliances must have valid certificates installed. Expired or untrusted certificates will result in browsers rejecting the HTTPS session and displaying errors to users.”

Other options:

A. Would prevent connection, but not result in certificate errors.

B. Blocked port 443 would prevent any connection, not cause cert errors.

C. Client-side certificates are not required unless mutual TLS is configured, which is not stated here.

Comprehensive and Detailed Explanation From Exact Extract:

Spanning Tree Protocol (STP) is a Layer 2 protocol that prevents loop conditions in redundant switch topologies. It automatically disables redundant links in a controlled way, allowing one active path at a time. When a switch fails, STP recalculates and activates an alternate path. In this case, loops are detected, but no broadcast storms occurred, indicating that STP is not in place or not configured properly. Implementing STP is a low-cost and effective solution to resolve these issues.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Switching Technologies and Loop Prevention”:

“STP prevents switching loops by dynamically identifying and disabling redundant paths. When a link failure occurs, STP re-converges to restore network connectivity.”

“STP is an essential protocol in redundant Layer 2 topologies to avoid broadcast and loop issues.”

Other options:

A. A Layer 3 switch adds routing functionality but does not prevent Layer 2 loops.

B. VLANs segment broadcast domains but do not inherently prevent physical loops.

D. Tagging (e.g., VLAN tagging) helps with segmentation but not with loop prevention.

Comprehensive and Detailed Explanation From Exact Extract:

While resource usage metrics (CPU, memory, disk, network) are important, the missing context here is user demand. Adding "Concurrent users" helps correlate resource utilization spikes with actual user load. For performance monitoring in web applications, concurrent sessions provide crucial insight into whether performance issues are demand-related.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Performance Monitoring and User Metrics”:

“Monitoring user load metrics such as concurrent users provides insight into performance degradation and capacity planning. These are critical for identifying thresholds and auto-scaling requirements.”

Other options:

A. 404 errors indicate broken links but don’t explain performance issues.

C. Number of orders tracks business activity, not system strain.

D. Active incidents belong in an ITSM system, not real-time performance monitoring.

================================================

Comprehensive and Detailed Explanation From Exact Extract:

A SIEM (Security Information and Event Management) solution ingests log data from multiple sources, correlates events, detects anomalies, and generates alerts based on predefined or dynamic rules. This makes SIEM the ideal solution for centralized logging and real-time threat detection.

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

“SIEM platforms aggregate, normalize, and analyze logs from diverse sources, providing real-time alerts and incident response support.”

Other options:

A. Syslog is a transport protocol — it doesn’t correlate or alert.

B. Event log monitoring is limited to individual systems.

C. Log management stores logs but doesn’t perform analysis or alerting.

Comprehensive and Detailed Explanation From Exact Extract:

NetFlow provides flow-level metadata about IP traffic without requiring inline deployment. It summarizes who is talking to whom, for how long, and how much data was exchanged. It’s ideal for behavior monitoring and threat detection when sent to a SIEM for correlation and analysis.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “NetFlow and Network Telemetry”:

“NetFlow provides visibility into traffic patterns, which can be used for anomaly detection and security analysis when integrated with SIEM platforms.”

Other options:

A. Syslog shows event-level data, but not network behavior.

B. SNMP traps monitor device status, not traffic behavior.

C. SSL decryption is complex and requires inline positioning.

Comprehensive and Detailed Explanation From Exact Extract:

To better secure administrative interfaces, the best practice is to isolate them from the production network by connecting the management ports to a separate, dedicated management network. This prevents unauthorized access from devices or users on the production subnet and reduces the attack surface.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Securing Network Infrastructure”:

“Management interfaces should be placed on a separate out-of-band management network, providing physical and logical separation from user and data traffic.”

This ensures that only trusted devices on the management network can access the administrative interfaces.

Other options:

B. Disabling unused ports is good practice but does not address the segregation of management traffic.

C. Placing admin interfaces and production traffic on the same VLAN exposes them to potential internal threats.

D. Firmware upgrades are important for security patches but do not isolate the interface.

Comprehensive and Detailed Explanation From Exact Extract:

A Content Delivery Network (CDN) distributes content across geographically distributed edge locations to provide faster access and higher quality to users, especially in areas with suboptimal connectivity to central data centers. By caching and serving content from edge servers near users, CDNs reduce latency and improve streaming performance globally.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “CDN and Cloud Edge Services”:

“CDNs provide globally distributed edge nodes for content caching and delivery, ensuring low-latency, high-bandwidth access for end users regardless of their location.”

Other options:

A. Reduces quality, contrary to the stated goal.

B. DNS-based routing helps with direction but does not solve content delivery or bandwidth issues.

C. Load balancers help distribute traffic locally, but do not provide edge caching or bandwidth optimization.

Comprehensive and Detailed Explanation From Exact Extract:

Infrastructure as Code (IaC) templates (e.g., Terraform, CloudFormation, ARM templates) allow for automated and repeatable VM deployments with preconfigured settings, includingnetworking, without requiring console access. This approach ensures consistency, security, and compliance.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Infrastructure as Code and Cloud Automation”:

“IaC enables declarative definition of cloud resources, supporting automated deployments that comply with organizational security and configuration policies.”

Other options:

B. SDKs require more complex coding and are less standardized.

C. API scripts are procedural and require manual management.

D. CLI is suitable for one-time use but not for repeatable deployments at scale.

Comprehensive and Detailed Explanation From Exact Extract:

STP (Spanning Tree Protocol) is a Layer 2 standard protocol that prevents switching loops in Ethernet networks by creating a loop-free logical topology. It can automatically block and unblock redundant paths based on network changes, ensuring reliability and avoiding broadcast storms.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Ethernet Loop Prevention and Switching Protocols”:

“STP is a standard Layer 2 protocol used to detect and prevent network loops, enhancing network stability in switched topologies.”

Other options:

B. SIP is a signaling protocol used in VoIP.

C. RTSP is for media streaming control.

D. BGP is a routing protocol, not for Layer 2 loop prevention.

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.”
