When setting up ExpressRoute, what is a required component?

Connection to Azure AD
Service Key
Replicated Storage Accounts
DNS Resolver

The correct answer is: Service Key

The required component when setting up ExpressRoute is the service key. The service key is essential as it uniquely identifies a specific ExpressRoute circuit. This key is provided by Azure and is used when establishing your circuit with your connectivity provider. It ensures that the connection is properly set up and validated between your on-premises network and Azure. In the context of setting up ExpressRoute, the other options do not play a required role. While Azure AD plays a significant role in managing identity and access in Azure, it is not a direct requirement for establishing an ExpressRoute connection. Similarly, replicated storage accounts relate to data redundancy and availability rather than the ExpressRoute configuration process. Lastly, a DNS resolver is used for domain name resolution and does not directly influence the creation or operation of an ExpressRoute circuit.
