CNX-001 Exam Dumps - CompTIA CloudNetX Exam

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.

Comprehensive and Detailed Explanation From Exact Extract:

A Web Application Firewall (WAF) is primarily used for inspecting HTTP/HTTPS requests and filtering out malicious traffic, such as SQL injection or cross-site scripting (XSS) attacks. However, WAFs do not restrict access based on geographical location by default.

To control access to the cloud-hosted application based on geographical location, the correct measure is to implement geo-restriction (geo-blocking). This technique limits access to cloud-based resources by using the source IP’s geographical origin. Geo-restriction is typically enforced at the cloud firewall or load balancer level.

Relevant Extract from CompTIA CloudNetX CNX-001 Official Objectives:

“Cloud access control policies can enforce geo-restriction settings, ensuring applications and services are only accessible from authorized geographic regions.”

Also found under “Security Controls in Cloud Deployments” section:

“Geo-restriction uses IP geolocation data to restrict access to services based on geographic criteria, supporting compliance and security requirements.”

A data lake is ideal for aggregating structured and unstructured data at scale. It supports storage and analysis of logs, performance metrics, and other telemetry data from various sources. Data lakes enable advanced analytics and machine learning for decision support.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Data Aggregation and Analytics”:

“Data lakes allow storage and analysis of high-volume, diverse data types, including logs and monitoring data. They support enterprise-wide visibility and strategic decision-making.”

Other options:

A. Relational databases are optimized for structured data and are less scalable for log aggregation.

B. CDNs deliver content, not used for data aggregation.

C. CIEM (Cloud Infrastructure Entitlement Management) governs cloud permissions, not logging.

Firewalls → VPN tunnel down

The IPsec tunnel between on-prem Firewall 1 and cloud Firewall 2 (ipip0/ipip2) is down, so no traffic can traverse to the cloud.

Application NSG → Misconfigured rule

There’s a “block” rule for 10.3.9.0/24 → 192.2.1.0/24, preventing legitimate on-prem clients from reaching Application A.

Comprehensive and Detailed Explanation From Exact Extract:

The traceroute shows that the traffic successfully passes through the application development network (192.168.2.1), to the server segment gateway (192.168.1.1), and reaches the serversegment firewall (192.168.4.1). However, it times out immediately after hitting 192.168.4.1, indicating that the traffic is being dropped or filtered at that firewall.

Because other users (outside of the application development segment) are able to SSH into the database server (192.168.1.9), the issue is not with the database server itself or the core network. This points to the server segment firewall blocking traffic originating from the application development subnet (192.168.2.0/24), which is a common practice in segmented network designs unless proper access rules are defined.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Network Segmentation and Firewall Rules”:

“Firewalls between network segments may enforce security policies that restrict access based on source/destination IP and port. Lack of proper allow rules can result in blocked traffic even if routing is successful.”

Other options:

A. The core firewall is not in the traceroute path; it is irrelevant to this specific flow.

B. NSGs (Network Security Groups) apply to cloud workloads, but the behavior and hop-by-hop flow suggest it is a firewall-level issue, not NSG misconfiguration.

D. Bandwidth issues would typically show packet loss or high latency, not consistent timeouts at a specific hop.
