HOTSPOT
Your network contains an Active Directory domain named contoso.com. The domain contains a single location
named Site1. The domain contains a server named Server1 that has the DHCP Server server role installed.
All client computers receive their IPv4 configurations dynamically.
The domain will expand to include a second locationnamed Site2. A server named Server2 will be deployed to
Site2. Site1 and Site2 will connect to each other by using a WAN link.
You need to ensure that the clients in both sites receive their IPv4 configurations from Server1.
In the table below, identify which actions must be performed on each server. Make only
one selection in each row. Each correct selection is worth one point.
Answer: 
Explanation:
Server 2 needs a routing protocol called “DHCP relay agent”
Why would you install Remote Access role on Server2 if it’s not configured to be the DHCP relay agent?
Also, the DHCP packets are sent only to Server2 – so Site2 objects will not receive DHCP configurations unless the packets are routed to them … from Server2. Server2 needs routing protocol. Server2 is connected to Server1 and will receive DHCP config automatically.
I think the Routing Protocol belongs to server 2.

Server1, Server2, Server2
Agreed, Create new scope on server 1, add remote access role on Server2 which then allows you to create a new routing protocol called DHCP Relay on Server2 which you point to Server1 – then clients will get their IPs from Server1 across the WAN.
“add a routing protocol” is a very ambiguous name. poor question. shows the quality of the exam creators.
Agree
I would say:
Server1: Create a new scope AND install the Remote Access Server Role
Server2: Add a routing procotol
There is another question in this exam which says ‘you need to configure your DHCP Server, Server1 as a DHCP Relay Agent. Which Server role should you install’ – to which the answer is ‘Remote Access’
