VCP-VCF Administrator 2024 Question 78
Select 3An administrator is preparing to enable Tanzu on a Cloud Foundation workload domain and needs to configure the overlay network. Which requirements must be met to ensure proper functionality of the overlay network?
- A
The NSX-T Edge nodes must have a minimum MTU of 1600 configured.
- B
The overlay network must use the VLAN ID reserved for NSX-T Management traffic.
- C
The BGP protocol must be enabled and configured between the edge nodes and the physical network.
- D
All hosts in the workload domain must have a consistent MTU of at least 1500 configured.
- E
The overlay network must be configured with a unique IP subnet range that does not overlap with other networks.
Show answer and explanation
Correct answers: A, C, E
Explanation
To enable Tanzu on a Cloud Foundation workload domain, the overlay network must meet specific requirements to support NSX-T functionality and connectivity. These include configuring a minimum MTU of 1600 on NSX-T Edge nodes, enabling BGP routing for dynamic connectivity, and ensuring the overlay network has a unique IP subnet range to prevent conflicts. Using a reserved VLAN or an insufficient MTU can lead to misconfigurations and service disruptions.
- A. Correct.
Correct: An MTU of 1600 or higher is required for the NSX-T overlay network to function properly and support Tanzu workloads.
- B. Incorrect.
Incorrect: The overlay network should not use the VLAN ID reserved for NSX-T Management traffic. Each network type (Management, Overlay, etc.) should have a dedicated VLAN.
- C. Correct.
Correct: BGP is required to establish dynamic routing between NSX-T Edge nodes and the physical network, enabling connectivity for the overlay network.
- D. Incorrect.
Incorrect: While a consistent MTU is important, an MTU of 1500 is insufficient for the overlay network. A minimum MTU of 1600 is required.
- E. Correct.
Correct: The overlay network must have a unique IP subnet range to avoid conflicts with other networks and ensure proper routing.
