An NSX administrator is creating a NAT rule on a Tier-0 Gateway configured in active-active high availability mode.
Which NAT rule type is supported for this configuration?
An NSX administrator is creating a NAT rule on a Tier-0 Gateway configured in active-active high availability mode.
Which NAT rule type is supported for this configuration?
For a Tier-0 Gateway configured in active-active high availability mode, the only supported NAT rule type is reflexive NAT. This is because active-active mode does not support stateful NAT configurations like source NAT (SNAT) or destination NAT (DNAT), as these can cause issues with asymmetrical paths. Reflexive NAT, also known as stateless NAT, is suitable for such configurations.
This question should be choose 3. This is from : https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/administration/GUID-E9B40B40-D0C4-4CC9-9706-E9C153FF1A6C.html Tier-0 NAT A tier-0 logical router in active-standby mode supports source NAT (SNAT), destination NAT (DNAT) and reflexive NAT. A tier-0 logical router in active-active mode supports reflexive NAT only. When a tier-0 logical router is running in active-active mode, you cannot configure stateful NAT where asymmetrical paths might cause issues. For active-active routers, you can configure reflexive NAT (sometimes called stateless NAT).
Answer: reflexive NAT Ref: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.4/administration/GUID-E9B40B40-D0C4-4CC9-9706-E9C153FF1A6C.html Tier-0 NAT A tier-0 logical router in active-standby mode supports source NAT (SNAT), destination NAT (DNAT) and reflexive NAT. A tier-0 logical router in active-active mode supports reflexive NAT only.
answer should be C https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.3/com.vmware.nsxt.admin.doc/GUID-73A54BCC-46D5-4A18-9DA6-870F279805BE.html
C is correct A tier-0 logical router in active-active mode supports reflexive NAT only https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/administration/GUID-E9B40B40-D0C4-4CC9-9706-E9C153FF1A6C.html
C: reflexive NAT
I agree: C "When a tier-0 or tier-1 logical router is running in active-active mode, you cannot configure stateful NAT where asymmetrical paths might cause issues. For active-active routers, you can use reflexive NAT"
