Refer to exhibits 1 and 2. A company uses a Metro Ethernet （Gigabit Ethernet） dedicated circuit to communicate between users （subnet B） and servers （subnet A） as shown in Exhibit 1. Both routers use OSPF to advertise the subnets. During a weekly management meeting， they realize that the WAN link is oversize. They have been using only 2 Mb/s in the worst-case scenario.

The Frame Relay service provider informs them that multicast traffic is not allowed to run over the service provider network. Which one of these options is best to enable the company to establish the OSPF neighbor adjacency？（） Use OSPF network broadcast，because it uses unicast to establish a neighbor relationship.。 Use OSPF network point-to-multipoint，because it uses unicast to establish a neighbor relationship.。 Use OSPF network point-to-point，because it uses unicast to establish a neighbor relationship.。 Use OSPF network point-to-multipoint nonbroadcast，because it establishes a neighbor relationship using unicast packets.。 Use OSPF network nonbroadcast，because it establishes a neighbor relationship using multicast.。
