WGU D412 AVN1 – Network Analytics and Troubleshooting, Task 1 2026 Update with complete solutions.

Helpdesk Ticket 1: Scenario: There are multiple reports of employees located in the USER_Net subnet who cannot get to , and they are being redirected to a suspicious site. A help desk technician states that the server team recently installed updates to DMZ_Server_3 which acts as the DNS Server for the organization. Objective (Identify and Resolve): Troubleshoot to identify the problem and take necessary steps to fix the problem. A. Using the information in the scenario for helpdesk ticket 1, do the following: 1. Provide a screenshot(s) that shows the problem has been identified… and resolved. 2. Provide a root cause analysis write-up by doing the following: a. Identify the tool(s) that you used and explain why you chose it to troubleshoot the problem. Clearly explain the tools used to identify why employees are being redirected to a suspicious site and why you chose them. Also describe the steps you took to identify the problem. Ping command was used to test if Windows_Desktop_1 (10.10.40.2) was able to reach DMZ_Server_3 (10.10.20.3). Test failed on both system to reach each other. nslookup was used to find what IP address is given for which was 10.10.20.2. b. Describe your solution to the problem including details of the troubleshooting steps that took place. Clearly explain the tools used to solve the problem and why you chose them. Also describe the steps you took to solve the problem. Helpdesk Ticket 2: Scenario: A complaint came in that a certain organization is hosting an illegal FTP site to download copyrighted software. The security team has provided a pcap file capturing all FTP traffic on the network. They've asked you to identify where the FTP site is being hosted. Objective (Identify): Analyze the PCAP file on the Host desktop (minimize GNS3 and look on the desktop for the file) and report back the IP address of the server and what files were observed being accessed. B. Using the information in the scenario for helpdesk ticket 2, do the following: 1. Provide a screenshot(s) that shows the problem has been identified. 2. Provide a root cause analysis write-up by doing the following: 2 a. Identify the tool(s) that you used and explain why you chose it to troubleshoot the problem. Examining the PCAP file in Wireshark lead to the discovery of the FTP site at 10.10.20.2. by filtering only FTP, you can see the IP requesting services and information is 10.10.60.1 and 10.10.20.2 is the one providing information and services. Helpdesk Ticket 3: Scenario: The host "Ubuntu_Server" can’t get to any of the assigned networks or the internet, which is preventing the server from pulling the required security patches. Objective (Identify): Identify the issue and report back the possible problem that the server/infrastructure team needs to address to allow network traffic to get to and from this device. C. Using the information in the scenario for helpdesk ticket 3, do the following: 1. Provide a screenshot(s) that shows the problem has been identified.
