A municipal engineer asks which encapsulation NSX-T uses for overlay traffic. Which protocol should the operator identify?
Select an answer to reveal the explanation.
Short Explanation
NSX-T wraps guest frames in Geneve, not in the old NSX-V VXLAN envelope. Think of Geneve as the labeled mailer the civic hosts use between tunnel endpoints. Horizon GRE and IPsec VPN are different tunnels, not the NSX-T overlay building block.
Full Explanation
NSX-T Data Center uses Geneve to encapsulate overlay frames between transport-node tunnel endpoints. VXLAN is the NSX-V overlay and is a common distractor on this associate exam, not the NSX-T building block. Horizon Unified Access Gateway GRE and IPsec site-to-site VPNs are separate technologies and are not the host overlay encapsulation.
