A NSX-T Data Center administrator wants to ensure that any machine on a public network can communicate with a Web VM running in a NSX-T Data Center environment.
Which NAT type must be created on the Tier-0 or Tier-1 Gateway to achieve this?
A. 1:1 NAT
B. Reverse NAT
C. DNAT
D. SNAT
Verified in ICM guide – C is the answer.
C is the correct answer – Pay attention to the wording – “wants to ensure that any machine on a public network CAN COMMUNICATE WITH a Web VM running in a NSX-T Data Center environment” – this would be Destination NAT.
i think is C
Is B the correct answer for this question?
According to the reference linked above, Reverse NAT is not supported. Support NAT types, DNAT, SNAT and Reflexive NAT: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.4/administration/GUID-73A54BCC-46D5-4A18-9DA6-870F279805BE.html
C (DNAT) would appear to be the correct answer for incoming packets, however it does leave open the question of the return path.
C is correct.
View from perspective of the VDC, if the VDC is the source-NAT used is SNAT, if the VDC is destination-NAT used is DNAT
