CNX-001 Exam Dumps : CompTIA CloudNetX Exam

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:

SD-WAN (Software-Defined Wide Area Network) enables private, encrypted connections over public internet links and supports policy-based routing for application-aware traffic steering. It offers centralized management, redundancy, and automatic path selection — all aligned with the stated requirements.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Software-Defined Networking and WAN Optimization”:

“SD-WAN uses secure tunnels over the public internet, supports dynamic path selection, and provides application-aware routing, making it ideal for multi-site enterprise connectivity without dedicated links.”

Other options:

A. MPLS requires dedicated circuits and is costly.

C. Site-to-site VPN provides security but lacks intelligent traffic steering.

D. ExpressRoute is a private connection to Azure, not suited for general internet-based multi-site connectivity.

Comprehensive and Detailed Explanation From Exact Extract:

A 403 Forbidden error indicates that the request was understood by the server but is refusing to fulfill it due to insufficient authorization. The developer is attempting to call a protected API that requires valid credentials such as an access key and signature (often used in HMAC-based APIs), but the values appear as Postman variables (e.g., {{rapyd_access_key}}), which suggests they were not replaced with actual credentials.

This typically means that the request lacks proper authentication or authorization headers, or the keys/signature are incorrect or missing. The presence of access_key, signature, salt, and timestamp in the request implies the API requires authentication, but the variables were not resolved or valid.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “API Security and Authentication”:

“A 403 error typically results from failed authentication or lack of proper authorization. Developers must ensure that tokens or signatures are valid, not missing, and properly injected.”

Other options:

A. 404 is the code for a missing resource, not 403.

C. A firewall rule would block the request entirely (e.g., no response or a 0 status), not result in a 403 from the server.

D. HTTP redirection issues typically result in 3xx codes, not 403.
