Your network contains a Routing and Remote Access server named RRAS1 and a DHCP server named DHCP1. RRAS1 and DHCP1 are located in different subnets.RRAS1 is configured to support VPN connections from the Internet. DHCP1 has a scope that provides IP addresses for the VPN connections.You need to ensure that VPN clients that connect to RRAS1 can receive IP addresses from DHCP1.What should you do？（）A. On DHCP1, configure a DHCP Relay Agent.B. On DHCP1, install the Routing role service.C. On RRAS1, configure a DHCP Relay Agent.D. On RRAS1, install the Routing role service.

In the open systems interconnection (OSI) reference model, "layer" means one of seven conceptually complete,(71) arranged groups of services, functions, and protocols, that extend across all open systems.Application layer provides means for the application(72) to access the OSI environment. Presentation layer provides for the selection of a common syntax for representing data.(73) layer provides the means necessary for cooperating presentation entities to organize and synchronize their dialog and to manage their data exchange. Transport layer provides a reliable end-to-end data transfer service. Network layer provides for the entities in the transport layer the means for transferring blocks of data, by(74) and switching through the network between the open systems in which those entities reside. Data link layer provides services to transfer data between network layer entities. Physical layer provides the mechanical, electrical, functional, and procedural means to establish, maintain and(75) physical connections for transfer of bits over a transmission medium.A．ranklyB．levellyC．layeredD．hierarchically
