CompTIA CNX-001 Dumps Questions Answers

Comprehensive and Detailed Explanation From Exact Extract:

Traffic mirroring allows a copy of network traffic — including headers and payloads — to be sent to an analysis tool or appliance for deep packet inspection. This is essential for security analysis, network troubleshooting, and performance diagnostics in cloud environments.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Packet Capture and Network Flow Monitoring”:

“Traffic mirroring enables the capture of full packet data, including payloads, for forensic or performance analysis within cloud networks.”

Other options:

A. Application monitoring focuses on app-level metrics, not packet inspection.

B. Syslog is log-based, not for inspecting packets.

D. Network flows (e.g., NetFlow, VPC flow logs) provide metadata (source, destination, size) but not full packet content.

Comprehensive and Detailed Explanation From Exact Extract:

Since the subnet and IPs were changed recently, and users are accessing the database through a web application, the likely issue is that DNS records have not been updated to reflect the new IP addresses. If DNS is pointing to old IPs, users will fail to reach the services even if they are up and reachable on the new subnet.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “DNS and Network Configuration Troubleshooting”:

“DNS misconfiguration is a common issue following IP address changes. If DNS entries are not updated accordingly, clients will attempt to reach services at outdated IPs.”

Other options:

A. No indication of web server misconfiguration is provided.

B. Firewall issues would affect all users, not just one.

D. The web server has a valid IP in the subnet range; no misconfiguration is indicated.

Comprehensive and Detailed Explanation From Exact Extract:

When SSL/HTTPS inspection is enabled on a firewall, it intercepts and decrypts HTTPS traffic. This requires the firewall to present its own trusted certificate to the client device. If that certificate is expired, the client browser will display a certificate error and block access to the application. This is a common misconfiguration that breaks HTTPS communication.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “TLS/SSL Inspection and Certificate Management”:

“SSL inspection appliances must have valid certificates installed. Expired or untrusted certificates will result in browsers rejecting the HTTPS session and displaying errors to users.”

Other options:

A. Would prevent connection, but not result in certificate errors.

B. Blocked port 443 would prevent any connection, not cause cert errors.

C. Client-side certificates are not required unless mutual TLS is configured, which is not stated here.
