Using an active-active deployment across two regions with at least two Availability Zones (AZs) each provides the highest level of fault tolerance and geographic redundancy. This ensures continuity even if an entire region or multiple zones become unavailable. In regulated sectors such as healthcare, this meets strict availability and disaster recovery requirements.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “High Availability and Multi-Region Design”:

“Active-active configurations across multiple regions and availability zones maximize uptime and ensure failover in the event of localized or regional failures.”

Other options:

B. Active-passive introduces delays in failover.

C. Active-active in one region offers no geographic redundancy.

D. Active-passive in two regions is slower and less efficient during failover.

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:

Spanning Tree Protocol (STP) is a Layer 2 protocol that prevents loop conditions in redundant switch topologies. It automatically disables redundant links in a controlled way, allowing one active path at a time. When a switch fails, STP recalculates and activates an alternate path. In this case, loops are detected, but no broadcast storms occurred, indicating that STP is not in place or not configured properly. Implementing STP is a low-cost and effective solution to resolve these issues.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Switching Technologies and Loop Prevention”:

“STP prevents switching loops by dynamically identifying and disabling redundant paths. When a link failure occurs, STP re-converges to restore network connectivity.”

“STP is an essential protocol in redundant Layer 2 topologies to avoid broadcast and loop issues.”

Other options:

A. A Layer 3 switch adds routing functionality but does not prevent Layer 2 loops.

B. VLANs segment broadcast domains but do not inherently prevent physical loops.

D. Tagging (e.g., VLAN tagging) helps with segmentation but not with loop prevention.

Using a spectrum analyzer to inspect the 6GHz frequency range allows the administrator to confirm the presence and source of interference. This step aligns with the “identify the problem” phase of the CompTIA troubleshooting methodology. Before making changes or documenting channels, the administrator must validate whether interference exists and collect diagnostic data.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Troubleshooting Methodology and Wireless Interference”:

“Spectrum analyzers provide a visual representation of frequency usage and interference in wireless bands, allowing administrators to isolate the root cause of degraded performance before implementing corrective actions.”

Other options:

A. Testing performance (Step 5 in the methodology) comes after identifying and resolving the issue.

C. Documentation is performed during the final step of troubleshooting.

D. Changing channels without evidence may worsen interference if the problem is not confirmed.

Comprehensive and Detailed Explanation From Exact Extract:

Risk transference is a risk management strategy in which the financial impact of a risk is shifted to a third party, such as an insurance company. In this scenario, the purchase of an insurance policy to cover potential damage or loss from a natural disaster is an example of transferring risk, not avoiding, mitigating, or accepting it.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide under “Risk Management Concepts”:

“Risk transference involves moving the responsibility or financial burden of a risk to a third party, often through the purchase of insurance or third-party service agreements.”

This approach is contrasted with mitigation (reducing risk), acceptance (living with the risk), or avoidance (eliminating the risk).

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.”

Comprehensive and Detailed Explanation From Exact Extract:

A Content Delivery Network (CDN) distributes content across geographically distributed edge locations to provide faster access and higher quality to users, especially in areas with suboptimal connectivity to central data centers. By caching and serving content from edge servers near users, CDNs reduce latency and improve streaming performance globally.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “CDN and Cloud Edge Services”:

“CDNs provide globally distributed edge nodes for content caching and delivery, ensuring low-latency, high-bandwidth access for end users regardless of their location.”

Other options:

A. Reduces quality, contrary to the stated goal.

B. DNS-based routing helps with direction but does not solve content delivery or bandwidth issues.

C. Load balancers help distribute traffic locally, but do not provide edge caching or bandwidth optimization.

Comprehensive and Detailed Explanation From Exact Extract:

A collapsed core design combines the core and distribution layers into a single tier, making it ideal for small-scale networks such as satellite campuses or branch offices. It reduces complexity, cost, and footprint while still supporting redundancy and scalability where needed.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Network Design Models”:

“For small to medium-sized deployments, a collapsed core topology reduces hardware and configuration complexity while maintaining essential functionality.”

Other options:

A. Hybrid refers to cloud/physical blends, not network topology.

B. Dual-layer isn’t a standard enterprise architecture reference.

C. Three-tier is overkill for small networks and adds unnecessary complexity.

Comprehensive and Detailed Explanation From Exact Extract:

Jitter refers to the variation in packet delay during transmission. In the ping output shown, the response times fluctuate significantly (11ms, 672ms, 849ms, 34ms), indicating inconsistent network performance. Such variation leads to a poor experience in real-time applications likevideo calls. High jitter causes packets to arrive out of order, resulting in stuttering or choppy audio/video.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Troubleshooting Real-Time Network Services”:

“Jitter is the deviation in packet arrival times and directly affects real-time communications such as VoIP and video conferencing. Consistent latency is tolerable; inconsistent latency (jitter) is disruptive.”

Other options:

A. Throughput refers to bandwidth and would cause consistent slowness.

C. Latency alone, if stable, is acceptable; it's the inconsistency here that causes issues.

D. Loss would be indicated by missing packets; the ping results show replies to all packets.

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.
