VCP-VCF Administrator 2024 Question 47
Select 3You are tasked with deploying an NSX Edge cluster in a VMware Cloud Foundation environment. During the setup, you are asked to configure Tunnel Endpoint (TEP) requirements. Which of the following are necessary considerations for TEP configuration to ensure proper deployment?
- A
Ensure that the TEP IP pool or DHCP is configured for the Edge node TEPs.
- B
Assign a VLAN-backed network for the TEP traffic.
- C
Configure TEPs on the same VLAN as the ESXi host TEPs.
- D
Set the MTU size to at least 1500 for TEP networks.
- E
Ensure that the TEP addresses are routable across Edge nodes and ESXi hosts.
Show answer and explanation
Correct answers: A, B, E
Explanation
Tunnel Endpoint (TEP) configuration is critical when deploying an NSX Edge cluster. TEPs enable the overlay networking by encapsulating traffic, and their configuration must include a valid IP pool or DHCP, a VLAN-backed network, and routable addresses. The MTU size must be set to at least 1600 to support encapsulated traffic, and while TEPs must communicate across nodes, they are not required to reside on the same VLAN.
- A. Correct.
Correct. TEPs for NSX Edge nodes must have an IP configuration, which can be provided via a configured IP pool or DHCP.
- B. Correct.
Correct. A VLAN-backed network is required to segregate TEP traffic and ensure proper communication between the Edge nodes and the ESXi hosts.
- C. Incorrect.
Incorrect. While TEPs for Edge nodes and ESXi hosts need to communicate, they are not required to be on the same VLAN, as long as proper routing exists.
- D. Incorrect.
Incorrect. The MTU size for TEP networks must be set to at least 1600, not 1500, to support overlay traffic.
- E. Correct.
Correct. TEP addresses must be routable to ensure communication between Edge nodes and ESXi host TEPs.
