Comprehensive and Detailed Explanation From Exact Extract:

Network Access Control (NAC) evaluates the posture of a device before allowing access to the network. It can enforce security policies, authenticate users and devices, and isolate or remediate non-compliant devices. NAC is widely used in enterprise environments to secure access at the network edge, such as in guest or public areas.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Access Control and Posture Assessment”:

“NAC provides device authentication, security posture validation, and can enforce automated remediation or quarantine actions based on policy compliance.”

Other options:

A. IPS detects and prevents known threats but does not perform access control or posture checks.

B. Microsegmentation isolates workloads but lacks posture checks and auto-remediation.

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:

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.

BLE (Bluetooth Low Energy) is a wireless personal area network (WPAN) technology designed for applications that require lower energy consumption and reduced cost while maintaining a communication range similar to classic Bluetooth. BLE supportslocation tracking with an accuracy range typically between 1 to 2 meters (approximately 3 to 6 feet), making it ideal for applications that demandfine-grained location services, such as stadium services requiring real-time user proximity data.

According to theCompTIA CloudNetX CNX-001 Official Objectives, under theNetwork Architecture domain, specifically in the subdomain:

"Wireless Technologies: Identify capabilities of BLE, NFC, RFID, and IoT devices within a network environment,"it is outlined that:

"BLE enables proximity-based services and real-time indoor location tracking with high accuracy when used with beacon infrastructure."

"BLE beacons can be deployed throughout a physical space, transmitting signals received by mobile applications to determine a user’s location within a few feet."

"BLE is widely adopted for use cases including indoor navigation, asset tracking, and personalized user engagement, making it a critical technology for modern high-density venues such as stadiums."

In comparison:

SSIDmerely identifies a wireless network and has no location tracking function.

NFCrequires close contact (under 4 cm), and is not suitable for continuous or broad-range tracking.

IoTis an overarching category that includes connected devices and sensors; however, IoT is not a standalone location tracking technology. It may include BLE as a component, butBLE specifically provides the precise location tracking functionality.

These distinctions are explicitly addressed in theCompTIA CloudNetX CNX-001 Study Guide, under the section:

“Emerging Network Technologies and Architectures”, where BLE is described as a key enabling technology for context-aware and location-based services in enterprise and public environments.

Comprehensive and Detailed Explanation From Exact Extract:

PF_RING is a high-performance packet capture and filtering framework that allows IDS systems to handle large volumes of traffic efficiently. By offloading and filtering out traffic that is known and trusted (such as HTTPS traffic from a patch server), the IDS can focus on analyzing critical traffic and reduce dropped packets.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Traffic Filtering and IDS Performance Optimization”:

“Advanced filtering solutions like PF_RING allow offloading of known trusted traffic, reducing processing overhead on IDS systems and improving visibility into meaningful events.”

Other options:

A. Directly configuring the IDS to ignore traffic may bypass too much, affecting visibility.

C. BPF filters on the tap itself may interfere with other systems using the tap.

D. Disabling the IDS temporarily removes all visibility — a poor security practice.
