2V0-41.24 Question 313
Select 3An administrator is reviewing the network topology in the NSX Manager UI to validate the Tier-1 gateway configuration for a new application deployment. The application requires connectivity to both an external network and an internal segment. Upon inspection, the administrator notices that the Tier-1 gateway is not forwarding traffic to the external network. Which of the following steps should the administrator take to resolve the issue?
- A
Ensure the Tier-1 gateway is correctly linked to a Tier-0 gateway.
- B
Verify that the Tier-1 gateway is configured with a default route.
- C
Check if the Tier-1 gateway has the necessary firewall rules to allow external traffic.
- D
Ensure the segments attached to the Tier-1 gateway have the correct VLAN tagging.
- E
Confirm that the Tier-1 gateway is in Active-Active mode.
Show answer and explanation
Correct answers: A, B, C
Explanation
In NSX-T, a Tier-1 gateway must be properly linked to a Tier-0 gateway to provide external connectivity. Additionally, the Tier-1 gateway needs a default route to know where to forward traffic destined for external networks. Firewall rules must also be checked to ensure traffic is not blocked at the Tier-1 gateway. While VLAN tagging and Active-Active mode are important for other aspects of network configuration, they are not directly related to validating or troubleshooting external connectivity in this scenario.
- A. Correct.
A Tier-1 gateway must be linked to a Tier-0 gateway to provide connectivity to external networks. Without this linkage, the Tier-1 gateway cannot forward traffic outside the NSX-T environment.
- B. Correct.
A default route on the Tier-1 gateway is required to direct traffic destined for external networks. Without a default route, the gateway will not know how to forward such traffic.
- C. Correct.
Firewall rules on the Tier-1 gateway might block external traffic. Verifying and configuring proper rules are essential to ensure traffic flow.
- D. Incorrect.
VLAN tagging is associated with segments and physical network configurations, but it is not directly related to the Tier-1 gateway's ability to forward traffic to external networks.
- E. Incorrect.
Active-Active mode is a configuration for redundancy and load balancing, but it does not impact the Tier-1 gateway’s ability to forward traffic to external networks.
