* C. Static IP allocation does not offer user-based access controls.
* D. MFA enhances security but is not directly aligned with all the listed requirements.
* F. Risk-based authentication evaluates threat levels but does not handle session timeout or location enforcement directly.
NEW QUESTION # 22
A SaaS company's new service currently is being provided through four servers. The company's end users are having connection issues, which is affecting about 25% of the connections. Which of the following is most likely the root cause of this issue?
- A. The service is using weighted load balancing with 40% of the traffic on server A, 20% on server B,
20% on server C, and server D is down. - B. The service is using round-robin load balancing through a DNS server with one server down.
- C. The service is using a least-connection load-balancing method with one server down.
- D. Load balancing is configured with a health check in front of these servers, and one of these servers is unavailable.
Answer: B
Explanation:
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.
NEW QUESTION # 23
A network administrator is configuring firewall rules to lock down the network from outside attacks. Which of the following should the administrator configure to create the most strict set of rules?
- A. URL filtering
- B. File blocking
- C. Network security group
- D. Allow List
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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.
NEW QUESTION # 24
A network load balancer is not correctly validating a client TLS certificate. The network architect needs to validate the certificate installed on the load balancer before progressing. Which of the following commands should the architect use to confirm whether the private key and certificate match?
- A. openssl x509 -noout -modulus -in cert.crt | openssl md5
openssl rsa -noout -modulus -in privkey.txt | openssl md5 - B. openssl-rsa -noout -modulus -in cert.crt | openssl md5
openssl-verify -noout -modulus -in privkey.txt | openssl md5 - C. openssl-list -noout -modulus -in cert.crt | openssl md5
openssl rsa -noout -modulus -in privkey.txt | openssl md5 - D. openssl req -in certificate.csr -verify
openssl-verify -noout -modulus -in privkey.txt | openssl md5
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To verify that the certificate and the private key match, one can extract the modulus from both files and compare their hash values. The correct syntax involves using openssl x509 to extract the modulus from the certificate, and openssl rsa to extract the modulus from the private key, followed by an MD5 hash to ensure they match.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "TLS/SSL Certificate Validation and Troubleshooting":
"To verify that the private key and certificate match, compare the modulus values. A mismatch results in failed TLS handshakes." Other options:
* A & C: Incorrect syntax (openssl-list and openssl-rsa are not valid commands).
* B: The commands shown are used to verify CSRs, not matching keys.

* C. Documenting lessons learned is the final step.
* D. Implementing the solution should only occur after the issue is confirmed.
NEW QUESTION # 31
A network architect must ensure only certain departments can access specific resources while on premises.
Those same users cannot be allowed to access those resources once they have left campus. Which of the following would ensure access is provided according to these requirements?
- A. Configuring geofencing with the IPs of the resources
- B. Enabling MFA for only those users within the departments needing access
- C. Implementing a PKI-based authentication system to ensure access
- D. Configuring UEBA to monitor all access to those resources during non-business hours
Answer: A
Explanation:
By defining an IP-based geofence around the on-premises network addresses where those resources reside, you ensure that only users connecting from inside the campus IP ranges can reach them. As soon as the same users leave that network (and thus fall outside the geofenced IP block), access is automatically denied.

The previous network hardware had administrative interfaces that were plugged into the existing network along with all other server hardware on the same subnet. Which of the following should the engineer do to better secure these administrative interfaces?
- A. Connect the switch management ports to a separate physical network.
- B. Disable unused physical ports on the switches to keep unauthorized users out.
- C. Set the administrative interfaces and the network switch ports on the same VLAN.
- D. Upgrade all of the switch firmware to the latest hardware levels.
Answer: A
Explanation:
Segregating management interfaces onto their own dedicated network ensures that administrative access is isolated from general user and server traffic, greatly reducing the attack surface and preventing lateral movement if the production network is compromised.
NEW QUESTION # 34
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 server does not have the correct network configuration.
- B. The DNS server is not resolving properly.
- C. The web application server is not forwarding the requests.
- D. The database server firewall is blocking the port to the database.
Answer: A
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.
