Comprehensive and Detailed Explanation From Exact Extract:

This scenario describes a classic example of social engineering. An attacker impersonated the help desk and convinced the user to change their password, likely to one the attacker controlled. Social engineering attacks manipulate human behavior to bypass technical security measures.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Social Engineering Threats”:

“Social engineering involves manipulating individuals to perform actions or divulge confidential information, such as passwords, often by impersonating trusted entities like IT support.”

Other options:

A. Initialization vector relates to encryption vulnerabilities.

B. On-path (formerly man-in-the-middle) requires network interception, which is not described here.

C. Evil twin is a rogue Wi-Fi AP attack, not applicable to this VPN login context.

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:

A Secure Web Gateway (SWG) provides cloud-based traffic filtering, URL filtering, SSL decryption, and content inspection without requiring traffic to be routed through an on-premises data center. It is ideal for both remote and hybrid users, enforcing security policies in a distributed environment.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Cloud-Based Security Solutions”:

“Secure Web Gateways allow cloud-hosted decryption and inspection of web traffic, enabling policy enforcement for remote and on-campus users without backhauling traffic to the data center.”

Other options:

B. Transit gateways connect VPCs and on-prem but don’t decrypt traffic.

C. VPNs provide encrypted tunnels but don’t inspect traffic.

D. IPS inspects traffic but is usually on-prem and not cloud-hosted.

E. NAC is used for access control, not traffic inspection.

Comprehensive and Detailed Explanation From Exact Extract:

When an application is moved from local deployment to a centralized cloud deployment, remote users must connect over the WAN. If the application is sensitive to delays, latency becomes a significant issue, especially across geographically distributed regions. This is a common performance concern for centralized applications serving remote offices.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Cloud Performance and WAN Connectivity”:

“Cloud-hosted applications accessed by remote users may suffer from latency-related performance issues. Optimization strategies may include CDN, caching, or edge deployment.”

Other options:

A. Throttling usually refers to bandwidth or rate-limiting, not general slowness.

B. Overutilization is possible, but infrastructure was said to be centralized and new.

C. Packet loss would likely cause disconnects or failures, not just slowness.

================================================

Comprehensive and Detailed Explanation From Exact Extract:

Reference architectures are pre-defined templates or blueprints provided by vendors, standardsbodies, or industry alliances (e.g., NIST, CIS, vendor frameworks) that define recommended practices for secure and reliable infrastructure design. They help ensure alignment with compliance, security controls, and industry-recognized configurations.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Architecture Standards and Security Best Practices”:

“Reference architectures guide the implementation of secure, scalable, and compliant infrastructure. They embody industry best practices and reduce misconfiguration risks in cloud and hybrid environments.”

Other options:

B. Licensing agreements pertain to software usage rights, not security alignment.

C. SLAs define service expectations, not design standards.

D. MOUs are informal agreements between parties, not technical or security frameworks.

Comprehensive and Detailed Explanation From Exact Extract:

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.”

Comprehensive and Detailed Explanation From Exact Extract:

According to the structured troubleshooting methodology outlined in the CNX-001 objectives, once a potential root cause is identified (in this case, a suspected firmware bug), the next step is to test the theory to confirm the cause before taking action. This helps prevent misdiagnosis and unnecessary configuration changes.

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

“After identifying symptoms and forming a theory of probable cause, the next step is to test the theory to verify it is the actual cause of the problem.”

Other options:

A. Establishing a plan of action comes after confirming the cause.

C. Documenting lessons learned is the final step.

D. Implementing the solution should only occur after the issue is confirmed.

Comprehensive and Detailed Explanation From Exact Extract:

Adding video surveillance that is focused on the cabinet enhances physical security by providing monitoring, deterrence, and forensic evidence in case of unauthorized access. Video surveillance complements existing layered access controls and is a recognized best practice for protecting high-value network assets.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Physical Security Controls”:

“Video surveillance provides 24/7 monitoring and records of physical access to critical infrastructure, supporting audit and incident investigation processes.”

Other options:

A. A statement of work is administrative and does not enhance physical security.

C. CISO accompaniment is impractical and not scalable.

D. Background checks are useful but are generally a prerequisite and not a real-time security control.

Comprehensive and Detailed Explanation From Exact Extract:

Round-robin DNS is a simplistic form of load balancing that does not perform health checks. If one of the four servers is down, DNS will still resolve its IP to 25% of users, resulting in failed connections. This matches the symptom of 25% failure rate — 1 out of 4.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Load Balancing Techniques and Availability”:

“Round-robin DNS distributes requests without regard for health status. Without external health checks, failed servers will continue to receive traffic, leading to partial service disruptions.”

Other options:

B. The percentages do not align with a 25% failure rate.

C. Least-connection algorithms usually have integrated health checks.

D. If health checks are active, the load balancer would not forward requests to a failed server.
