2V0-41.24 Question 293
Select 3You are tasked with validating the logical switching configuration in an NSX-T Data Center environment. Using the network topology feature in the NSX Manager UI, you observe that a logical switch is not receiving traffic from a connected Tier-1 Gateway. What steps should you take to troubleshoot this issue?
- A
Verify that the Tier-1 Gateway is successfully linked to an upstream Tier-0 Gateway.
- B
Ensure that the logical switch is attached to the correct segment port on the Tier-1 Gateway.
- C
Validate that the VMs connected to the logical switch have the correct IP addresses and network configurations.
- D
Check if the Edge Transport Node associated with the Tier-1 Gateway has sufficient resource availability.
- E
Inspect the firewall rules applied to the logical switch to confirm they are not blocking traffic.
Show answer and explanation
Correct answers: B, C, E
Explanation
Validating the logical switching configuration using the network topology involves ensuring that all components are correctly connected and configured. The logical switch must be properly attached to the Tier-1 Gateway, and the VMs connected to it should have accurate network settings. Additionally, firewall rules can block traffic, so these must be checked to confirm they allow traffic flow. These steps help isolate and resolve the issue of the logical switch not receiving traffic.
- A. Incorrect.
While the Tier-1 Gateway must be connected to a Tier-0 Gateway for north-south traffic, this is not directly relevant to verifying traffic flow to the logical switch.
- B. Correct.
If the logical switch is not correctly attached to the Tier-1 Gateway’s segment port, traffic will not flow to or from the logical switch.
- C. Correct.
Incorrect VM IP addresses or misconfigured network settings can prevent traffic from being sent to the logical switch, so this should be validated.
- D. Incorrect.
Resource availability on the Edge Transport Node is important but not directly related to the issue of traffic not reaching the logical switch.
- E. Correct.
Firewall rules applied to the logical switch can block traffic and should be inspected to ensure they allow the intended communication.
