CompTIA CNX-001 Dumps

Comprehensive and Detailed Explanation From Exact Extract:

With GitOps, all infrastructure changes are tracked as code and committed to version-controlled repositories. When the main branch is protected, changes should not be committed directly. Instead, best practices require that a new feature or change branch be created, followed by a pull request (PR) for peer review and approval before merging into the protected branch.

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

“In GitOps workflows, changes are made in feature branches, reviewed via pull requests, and merged into protected branches only after validation, ensuring auditability and control over infrastructure deployments.”

Other options:

A. Direct commits to protected branches are restricted and violate GitOps practices.

C. The development branch may exist, but the question specifies main is the default, and the correct process requires a PR.

D. Rebase is for integrating histories, not submitting approved changes.

An Allow List (also known as Whitelisting) is the most restrictive firewall rule approach. It blocks all traffic by default and only permits explicitly defined trusted IPs, URLs, or applications. This minimizes the attack surface and ensures that only known, safe traffic is allowed into the network.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Firewall and Security Rule Configuration”:

“Whitelisting or Allow Listing enforces a default-deny security posture by permitting only specified trusted sources. This approach offers the highest level of control and reduces exposure to unknown threats.”

Other options:

A. URL filtering restricts content access but is not as strict as allow lists.

B. File blocking targets malicious payloads but doesn’t limit traffic sources.

C. Network Security Groups (NSGs) are effective but broader in scope; they use allow/deny rules but may not be as tightly controlled as explicit allow lists.

In the 2.4 GHz Wi-Fi band, channels overlap due to how the frequency spectrum is divided. To prevent co-channel and adjacent-channel interference, only non-overlapping channels should be used. According to the IEEE 802.11 standard and best practices outlined in the CompTIA CloudNetX CNX-001 Study Guide under “Wireless Network Optimization,” the three non-overlapping channels in the 2.4 GHz band are:

Channel 1 (2.412 GHz)

Channel 6 (2.437 GHz)

Channel 11 (2.462 GHz)

These channels are spaced far enough apart to avoid interference, even when operating in close proximity. Using overlapping channels (as in options A, B, and D) causes signal degradation and poor performance due to increased contention and retransmissions.

Relevant Extract from CompTIA CloudNetX CNX-001:

“Wi-Fi networks operating on the 2.4 GHz band should use channels 1, 6, and 11 to ensure maximum throughput and minimal interference in environments with multiple access points.”
