DC sure.
Saw in the ICM 4.0 :
NAT64 is a mechanism for translating IPv6 packets into IPv4 packets:
• NAT64 allows IPv6-only clients to communicate with IPv4 servers.
• Changes are not needed in the IPv6 or IPv4 nodes.
• NAT64 is supported on Tier-0 and Tier-1 gateways.
• NAT64 is stateful and requires the Tier-0 gateway to be deployed in active-standby mode. • NAT64 requires the Tier-1 gateway to be configured with an active-standby edge cluster.
As per VMware's NSX-T lecture manual:
NAT64 is a mechanism for translating IPv6 packets into IPv4 packets:
• NAT64 allows IPv6-only clients to communicate with IPv4 servers.
• Changes are not needed in the IPv6 or IPv4 nodes.
• NAT64 is supported on Tier-0 and Tier-1 gateways.
• NAT64 is stateful and requires the Tier-0 gateway to be deployed in active-passive mode.
• NAT64 requires the Tier-1 gateway to be configured with an active-standby edge cluster.
Therefore, options C & D are correct.
1. NAT64 requires the Tier-1 gateway to be configured in active-active mode: You need to configure the tier-1 gateway in active-active mode to enable NAT64, as this mode supports stateless NAT operations. NAT64 is not supported on tier-1 gateways in active-standby mode, as this mode supports stateful NAT operations.
2. NAT64 is supported on Tier-1 gateways only: You can only configure NAT64 on tier-1 gateways, as they provide local services for segments. NAT64 is not supported on tier-0 gateways, as they provide global services
for routing and connectivity.
