VCP-VMC 2024 Question 197
Select 3A VMware Cloud on AWS deployment is experiencing connectivity issues between virtual machines in different logical networks. The network administrator has verified that the segments are properly configured in NSX-T, but the issue persists. What steps should the administrator take to troubleshoot this internetworking issue?
- A
Verify that the Tier-1 Gateway is properly connected to the Tier-0 Gateway.
- B
Check the firewall rules in NSX-T to ensure they allow traffic between the logical networks.
- C
Confirm that the VMs are correctly assigned to the appropriate network segments.
- D
Validate that the Edge Cluster has sufficient resources for proper routing.
- E
Ensure that the DHCP service is enabled on the logical segments.
Show answer and explanation
Correct answers: A, B, C
Explanation
Internetworking issues in VMware Cloud often stem from misconfigurations in logical routing, firewall rules, or incorrect segment assignments. Routing between segments relies on proper connectivity between the Tier-1 and Tier-0 Gateways, while firewall rules must permit the required traffic. Ensuring VMs are assigned to the correct segments is also essential. However, Edge Cluster resource constraints or DHCP issues are less likely to be the cause in this specific scenario.
- A. Correct.
A misconfigured or unconnected Tier-1 Gateway to the Tier-0 Gateway can break routing between logical networks. This is a critical step in troubleshooting internetworking.
- B. Correct.
Firewall rules in NSX-T can block traffic between logical networks if not configured correctly. Verifying the rules can help identify the root cause.
- C. Correct.
Incorrectly assigning VMs to network segments can result in connectivity issues. This should always be checked during troubleshooting.
- D. Incorrect.
While Edge Cluster resources are important for routing, a lack of resources would likely manifest in degraded performance or errors rather than complete connectivity failure between logical networks.
- E. Incorrect.
DHCP services are unrelated to routing between logical networks. A lack of DHCP would result in IP assignment issues, not inter-network connectivity problems.
