CNX-001 Exam Dumps : CompTIA CloudNetX Exam

Comprehensive and Detailed Explanation From Exact Extract:

The best way to prevent unscheduled outages caused by Infrastructure as Code (IaC) changes is to implement automated review and approval gates in the CI/CD pipeline. This ensures that all changes undergo validation, peer review, testing, and possibly approval from stakeholders before being deployed, thus reducing the likelihood of production-impacting issues.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “CI/CD Security and IaC Controls”:

“Incorporating approval gates and automated validation into CI/CD pipelines helps detect misconfigurations and unauthorized changes before deployment, reducing the risk of outages.”

Other options:

A. Making changes directly to the master branch violates best practices.

B. Self-review (by the author) lacks objectivity and fails peer validation.

C. Forking creates a copy but does not introduce formal validation processes.

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.

WAF (Web Application Firewall) protects web applications by inspecting HTTP/S traffic to and from the application. It filters, monitors, and blocks malicious traffic and exploits targeting web application vulnerabilities. WAFs are deployed at the edge, often in conjunction with load balancers, and are ideal for mitigating threats like SQL injection, cross-site scripting, and protocol violations.

NSG (Network Security Group) is a native security feature offered by many cloud providers (such as Azure), functioning similarly to a firewall. NSGs control inbound and outbound traffic at the virtual network interface, subnet, or VM level, allowing engineers to define allowed or denied traffic rules.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide under “Cloud Workload Protection & Security Tools”:

“WAFs are critical for protecting web-facing applications in public cloud environments.”

“Network Security Groups (NSGs) are used to enforce access policies on cloud-based virtual networks, providing filtering and segmentation at the instance or subnet level.”
