The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps.

The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running , by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.

RIP has an administrative distance (AD) of 120, while EIGRP has an administrative distance of 90, so the router will discard any route with a higher AD than 90 to that same network.

To stop possible address conflicts , a DHCP client will use gratuitous ARP (broadcast an ARP request for its own IP address) to see if another host responds.

The Transport layer uses virtual circuits to create a reliable connection between two hosts.

Standard IP access lists use the numbers 1 - 99 and 1300 - 1999 and filter based on source IP address only. Option C is incorrect because the mask must be in wildcard format.

The show ip eigrp neighbors command allows you to check the IP addresses as well as the retransmit  interval and queue counts for the neighbors that have established an adjacency.
