2V0-41.24 Question 442
Single answerAn administrator is troubleshooting a connectivity issue between two virtual machines (VMs) located on different segments within an NSX-T Data Center environment. The administrator wants to determine where the packet is dropped in the network path using Traceflow. Which step should the administrator perform first?
- A
Select the source and destination VMs, and initiate a Traceflow test.
- B
Check the system's dashboard for any critical alerts related to the virtual network.
- C
Analyze the traffic statistics on the Tier-0 Gateway logical interface.
- D
Verify the firewall rules applied to the segments connected to the VMs.
Show answer and explanation
Correct answer: A
Explanation
Traceflow is a powerful tool in NSX-T Data Center for identifying network connectivity issues. It starts by simulating a packet's path and checks where it is dropped or delayed. The first step in using Traceflow is to select the source and destination VMs, initiate the test, and then analyze the results to pinpoint the issue. Other troubleshooting methods like checking the dashboard or analyzing traffic statistics can be used later if Traceflow does not resolve the issue.
- A. Correct.
This is correct because Traceflow requires the administrator to select the source and destination VMs and initiate the test to identify where the packet is dropped along the path.
- B. Incorrect.
While the dashboard can provide useful insights, it does not directly allow for identifying packet drops along the path between two VMs.
- C. Incorrect.
Analyzing traffic statistics on the Tier-0 Gateway logical interface may help in diagnosing overall traffic issues but does not provide specific packet drop details between two VMs.
- D. Incorrect.
Firewall rule verification is important but is not the first step in using Traceflow to identify where a packet drop is occurring.
