- A. Test the theory to determine cause.
Document lessons learned. - B. Establish a plan of action to resolve the issue.
- C. Implement the solution.
Answer: A
Explanation:
Before taking corrective action, you need to verify that the new firmware is indeed the root cause, such as by rolling back to the previous version in a controlled test or reproducing the failure in a lab, so you're sure your fix addresses the actual problem.
NEW QUESTION # 46
An administrator must ensure that credit card numbers are not contained in any outside messaging or file transfers from the organization. Which of the following controls meets this requirement?
- A. Encryption in transit
- B. Egress filtering
- C. Intrusion detection system
- D. Data loss prevention
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Data Loss Prevention (DLP) solutions scan messages and file transfers for sensitive data patterns, such as credit card numbers or social security numbers. DLP can block, log, or alert when such information is detected attempting to leave the organization.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Data Protection and Compliance Controls":
"DLP systems identify and restrict the transmission of sensitive data such as credit card numbers, enforcing organizational data handling policies." Other options:
* A. IDS detects threats but doesn't enforce data content policies.
* B. Egress filtering restricts destinations but not content.
* D. Encryption protects data in transit, not its content compliance.
NEW QUESTION # 47
A user reports an issue connecting to a database server. The front-end application for this database is hosted on the company's web server. The network engineer has changed the network subnet that the company servers are located on along with the IP addresses of the servers. These are the new configurations:
New subnet for the servers is 10.10.10.64/27
Web server IP address is 10.10.10.101
Database server IP is 10.10.10.93
Which of the following ismostlikely causing the user's issue?
- A. The web application server is not forwarding the requests.
- B. The database server firewall is blocking the port to the database.
- C. The DNS server is not resolving properly.
- D. The web server does not have the correct network configuration.
Answer: D
Explanation:
With a /27 mask on 10.10.10.64/27, valid host addresses run from 10.10.10.65 through 10.10.10.94. The database server's IP (10.10.10.93) is in that range, but the web server's IP (10.10.10.101) falls outside it-so it's mis-configured and cannot reach the database.

- A. Establish a plan of action to resolve the issue.
- B. Implement the solution.
- C. Test the theory to determine cause.
- D. Document lessons learned.
Answer: C
Explanation:
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.
NEW QUESTION # 50
A network administrator must connect a remote building at a manufacturing plant to the main building via a wireless connection. Which of the following should the administrator choose to get thegreatestpossible range from the wireless connection? (Choose two.)
- A. Built-in antenna
- B. 6GHz
- C. 2.4GHz
- D. Omnidirectional antenna
- E. 5GHz
- F. Patch antenna
Answer: C,F
Explanation:
2.4 GHz: The lower-frequency 2.4 GHz band propagates farther and better penetrates obstacles than 5 GHz or
6 GHz, giving you greater link distance.
Patch antenna: A directional (patch) antenna focuses RF energy into a narrow beam, maximizing gain and range between two fixed points - the best for a long-haul wireless link.
NEW QUESTION # 51
A network engineer at an e-commerce organization must improve the following dashboard due to a performance issue on the website:
Which of the following is themostuseful information to add to the dashboard for the operations team's?
- A. 404 errors
- B. Number of orders
- C. Concurrent users
- D. Number of active incidents
Answer: C
Explanation:
Adding a concurrent-user count gives you the key context you're missing: it ties spikes in CPU, memory, disk I/O, and network traffic directly to how many people are actively hitting the site. You can then see whether performance issues align with increases in user load, enabling more targeted capacity planning and troubleshooting.
NEW QUESTION # 52
A company is experiencing Wi-Fi performance issues. Three Wi-Fi networks are available, each running on the 2.4 GHz band and on the same channel. Connecting to each Wi-Fi network yields slow performance.
Which of the following channels should the networks be configured to?
- A. Channel 1, Channel 6, and Channel 11
- B. Channel 3, Channel 5, and Channel 10
- C. Channel 2, Channel 4, and Channel 9
- D. Channel 1, Channel 2, and Channel 3
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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."
NEW QUESTION # 53
A company provides an API that runs on the public cloud for its customers. A fixed number of VMs host the APIs. During peak hours, the company notices a spike in usage that results in network communication speeds slowing down for all customers. The management team has decided that access for all customers should be fair and accessible at all times. Which of the following is the most cost-effective way to address this issue?
- A. Enable throttling on APIs.
- B. Increase the MTU on the VMs.
- C. Increase the number of VMs running APIs.
- D. Use an allow list for customers using APIs.
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
API throttling limits the number of requests a user or system can make in a given time frame. This ensures that no single customer overwhelms the service, maintaining fair access and stability for all users during peak usage periods. It is cost-effective as it avoids unnecessary resource scaling.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "API Management and Traffic Control":
"Throttling allows for controlled usage of APIs, preventing service degradation and ensuring equitable access during high traffic periods." Other options:
* A. Allow lists control access, not traffic volume.
* B. Increasing VMs increases cost and may not scale linearly.
* D. MTU settings affect packet size but not API-level fairness or traffic spikes.
NEW QUESTION # 54
A network security administrator needs to set up a solution to:
Gather all data from log files in a single location.
Correlate the data to generate alerts.
Which of the following should the administrator implement?
- A. Syslog
- B. SIEM
- C. Log management
- D. Event log monitoring
Answer: B
Explanation:
A Security Information and Event Management system centralizes log collection from disparate sources and applies correlation rules to generate actionable alerts.
NEW QUESTION # 55
A company is expanding operations and opening a new facility. The executive leadership team decides to purchase an insurance policy that will cover the cost of rebuilding the facility in case of a natural disaster.
Which of the following describes the team's decision?
- A. Disaster recovery
- B. Business continuity
- C. Memorandum of understanding
- D. Risk transference
Answer: D
Explanation:
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).
NEW QUESTION # 56
A network architect is choosing design options for a new SD-WAN installation that has the following requirements:
* All network traffic from the cloud must pass through inspection devices in a dedicated data center.
* Ensure redundancy.
* Centralize egress traffic.
Which of the following network topologies best meets these requirements?
- A. Point-to-point
- B. Partial mesh
- C. Star
- D. Hub-and-spoke
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The Hub-and-Spoke topology is ideal for SD-WAN environments where traffic from branch offices or cloud workloads must route through a central location (the hub) for inspection, monitoring, or security enforcement.
This structure centralizes egress and allows for redundant spoke paths via the hub. It also simplifies control and enforces compliance policies.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "SD-WAN Topologies and Cloud Egress Strategies":
"In a hub-and-spoke topology, spokes (remote offices or cloud nodes) connect through a central hub, allowing for centralized egress, traffic inspection, and simplified routing." Other options:
* A. Point-to-point doesn't scale and lacks centralized control.
* C. Star topology is similar to hub-and-spoke but is more rigid and less suited for SD-WAN scalability.
* D. Partial mesh allows direct spoke-to-spoke communication, bypassing centralized inspection.
NEW QUESTION # 57
A developer reports errors when trying to access a web application. The developer uses Postman to troubleshoot and receives the following error:
* HTTP Status: 403 Forbidden
* Headers include authentication-related variables such as access_key, signature, salt, and timestamp
* The request is a GET request to a payment methods API
Which of the following is the cause of the issue?
- A. Incorrect HTTP redirection
- B. Too restrictive NGFW rule
- C. Requested element not found
- D. Lack of user authentication
Answer: D
Explanation:
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.

NEW QUESTION # 59
A company has a 40Gbps network that uses a network tap to inspect the traffic using an IDS. The IDS usually performs normally except when the servers are downloading patches from their local update repository
10.10.10.139 using HTTPS. During the patch windows, the IDS cannothandle the extra load and drops a significant number of packets. Which of the following would allow a network engineer to prevent this issue without compromising the network visibility?
- A. Scheduling a cron job to stop the IDS service during the patch window
- B. Using PF_RING offload to filter out "host 10.10.10.139 and port 443"
- C. Adding a "dst host 10.10.10.139" BPF on the tap
- D. Configuring the IDS to ignore traffic from 10.10.10.139
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
PF_RING is a high-performance packet capture and filtering framework that allows IDS systems to handle large volumes of traffic efficiently. By offloading and filtering out traffic that is known and trusted (such as HTTPS traffic from a patch server), the IDS can focus on analyzing critical traffic and reduce dropped packets.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Traffic Filtering and IDS Performance Optimization":
"Advanced filtering solutions like PF_RING allow offloading of known trusted traffic, reducing processing overhead on IDS systems and improving visibility into meaningful events." Other options:
* A. Directly configuring the IDS to ignore traffic may bypass too much, affecting visibility.
* C. BPF filters on the tap itself may interfere with other systems using the tap.
* D. Disabling the IDS temporarily removes all visibility - a poor security practice.
