CNX-001 Exam Questions Tutorials

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:

Failing to log out of a privileged session on a shared device leaves that session accessible to the next user, potentially granting unauthorized access to administrative functions. This scenario aligns with privilege escalation, where an individual gains access to higher-level permissions than they are authorized to have.

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

“Privilege escalation occurs when a user gains elevated access rights, often due to misconfigurations or negligence, such as unattended administrative sessions.”

Other options:

A. IP spoofing involves falsifying source IP addresses.

B. Zero-day refers to unknown software vulnerabilities.

C. On-path attacks involve intercepting traffic, not session misuse on local devices.

Comprehensive and Detailed Explanation From Exact Extract:

2.4GHz has longer range and better wall penetration than higher frequencies like 5GHz or 6GHz.A patch antenna (a type of directional antenna) focuses the signal in one direction, greatly improving range and reliability over long distances between buildings.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Wireless Deployment and Antenna Selection”:

“2.4GHz offers extended range over 5GHz. Directional antennas such as patch antennas concentrate signals toward a target, improving distance communication.”

Other options:

B & C. Higher frequencies provide faster speeds but shorter range.

D. Omnidirectional antennas spread signal in all directions, not ideal for point-to-point.

F. Built-in antennas are generally low gain and insufficient for building-to-building links.

Comprehensive and Detailed Explanation From Exact Extract:

NAT64 allows IPv6-only devices to communicate with IPv4-only systems. It translates IPv6 addresses to IPv4 and vice versa. This is essential in mixed environments where backward compatibility is needed, and cannot be resolved simply by dual-stacking or bridging.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “IP Version Compatibility and Translation”:

“NAT64 allows seamless communication between IPv6-only clients and IPv4-only servers by translating address formats and protocol headers.”

Other options:

A. Adding IPv6 to internal servers requires changes to all internal devices and does not scale well.

B. Bridging does not handle protocol translation.

C. Changing IPv6 servers back to IPv4 violates the requirement for IPv6-only configuration.
