A cloud administrator is tasked with creating a new network segment in the software-defined data center that utilizes the corporate DHCP server to provide IP addresses. What is the proper sequence to create the required network segments?
A.
1. Create a new segment attached to the Tier-0 gateway 2. Configure the segment DHCP ip-helper
B.
1. Create a DHCP server profile 2. Create a new segment attached to the Tier-0 gateway 3. Configure the segment DHCP config to utilize the new DHCP server profile
C.
1. Create a new segment attached to the Tier-1 gateway 2. Configure the segment DHCP ip-helper
D.
1. Create a DHCP relay profile 2. Create a new segment attached to the Tier-1 gateway 3. Configure the segment DHCP config to utilize the new DHCP relay profile
A. Configure segment DHCP ip-helper: An IP helper points to a specific DHCP server within the SDDC itself. This wouldn't be appropriate if you want to utilize an external corporate DHCP server.
B. Create a DHCP server profile: While creating a DHCP server profile is useful for deploying a DHCP server within the SDDC, it's not necessary when using an external corporate DHCP server.
C. Attach segment to Tier-0 gateway: Tier-0 gateways typically handle east-west traffic within the SDDC. For DHCP relay to an external server, attaching the segment to the Tier-1 gateway is more appropriate.
Question said: "corporate DHCP server" - so DHCP already EXISTS. B for sure incorrect. We need to create DHCP relay profile (which contains corp DHCP server IP) and attach to segment. We do this normally at Tier-1 GW (not T0) with NSX 4.x
Key thing here is VMC uses relay profile, so answer is D, you can't configure the T0 gw.

correction : A. 1. Create a new segment attached to the Tier-0 gateway
2. Configure the segment DHCP ip-helper
Explanation:
When you want a segment in the VMware NSX environment to utilize an external DHCP server, you need to create the segment and then set the DHCP relay, which is the DHCP ip-helper. This tells the segment to relay DHCP requests to a specific external DHCP server. In most cases, this would be done on segments attached to the Tier-0 gateway when you're intending to use an external DHCP server.
you dont have access to T0 ... and it's a Relay not a server profile
