2V0-41.24 Question 340
Single answerAn administrator is configuring a VMware NSX environment and needs to establish communication between a Tier-0 and a Tier-1 gateway. The Tier-0 gateway will handle north-south traffic, while the Tier-1 gateway will manage workloads within a specific tenant. Which configuration step is required to successfully connect the Tier-0 and Tier-1 gateways?
- A
Enable BGP on the Tier-0 gateway and set up a BGP neighbor relationship with the Tier-1 gateway.
- B
Establish a Service Interface on the Tier-1 gateway and connect it to the Tier-0 gateway.
- C
Create a Tier-1 Gateway and configure a Tier-0 Gateway as its upstream gateway.
- D
Configure a static route on the Tier-0 gateway pointing to the Tier-1 gateway.
Show answer and explanation
Correct answer: C
Explanation
In VMware NSX, Tier-0 and Tier-1 gateways are connected by defining the Tier-0 gateway as the upstream gateway for the Tier-1 gateway. This logical connection enables the Tier-1 gateway to send and receive traffic through the Tier-0 gateway, facilitating communication between workloads and external networks. Additional configurations like BGP or static routes are not necessary for this specific connection.
- A. Incorrect.
Enabling BGP is not required to connect Tier-0 and Tier-1 gateways. BGP is typically used for external routing configurations.
- B. Incorrect.
Service Interfaces are used for connecting gateways to external services or physical networks, not for connecting Tier-0 and Tier-1 gateways.
- C. Correct.
To connect a Tier-1 gateway to a Tier-0 gateway, the administrator must specify the Tier-0 gateway as the upstream gateway during the Tier-1 configuration. This establishes the logical connection between the two tiers.
- D. Incorrect.
Static routes are not required to establish connectivity between Tier-0 and Tier-1 gateways since the NSX infrastructure handles the routing between these tiers automatically once they are connected.
