2V0-41.24 Question 118
Select 3An organization is deploying a VMware NSX environment to support a multi-tier application. The design requires that a Tier-0 gateway provides the north-south connectivity to the physical network, while a Tier-1 gateway handles routing for the internal application tiers. During the configuration process, what steps must be correctly performed to ensure the Tier-1 gateway communicates with the Tier-0 gateway?
- A
Establish a service interface on the Tier-1 gateway for external connectivity.
- B
Link the Tier-1 gateway to the Tier-0 gateway by configuring the 'Set Gateway' option in the Tier-1 settings.
- C
Enable route redistribution from Tier-1 to Tier-0 for required routes.
- D
Assign static routes on the Tier-0 gateway pointing to the Tier-1 gateway subnets.
- E
Configure a downlink segment on the Tier-1 gateway for internal workload connectivity.
Show answer and explanation
Correct answers: B, C, E
Explanation
To configure a Tier-0 and Tier-1 gateway for proper communication, the Tier-1 gateway must be linked to the Tier-0 gateway, route redistribution must be enabled for route propagation, and downlink segments must be configured on the Tier-1 gateway for internal workload connectivity. These steps establish the hierarchy and enable seamless communication between internal workloads and the external network.
- A. Incorrect.
This is not required because the Tier-1 gateway does not need a service interface for communication with the Tier-0 gateway. Service interfaces are used for specific use cases like NAT or DHCP services.
- B. Correct.
This is correct. Linking the Tier-1 gateway to the Tier-0 gateway is essential to establish the hierarchical routing relationship between the two gateways.
- C. Correct.
This is correct. Route redistribution ensures that routes learned by the Tier-1 gateway are advertised to the Tier-0 gateway, enabling proper north-south routing.
- D. Incorrect.
This is incorrect. Static routes are not required for Tier-0 and Tier-1 gateway communication as the NSX routing model is dynamic once properly configured.
- E. Correct.
This is correct. A downlink segment is necessary on the Tier-1 gateway to provide connectivity to internal workloads, which then communicate via the gateway hierarchy.
