?Match each correct item with the statement below. 

A. A number indicating a protocol's reliability, with lower values being given higher priority. This assignment can be changed by a network administrator when one protocol should take precedence over a previously higher-rated protocol on a network.?
B. A globally unique number that identifies an autonomous system. ASNs work similarly to IP addresses that identify individual nodes on a network. Each ASN now consists of 32 bits instead of 16 bits, and they are assigned by IANA.?
C. The router on a network that accepts all unroutable messages from other routers.?
D. ?A router that connects an autonomous system with an outside network-for example, the router that connects a business to its ISP.
E. A router that directs data between networks within the same autonomous system.?
F. ?The delay between the transmission of a signal and its receipt.
G. The largest IP packet size in bytes allowable by routers in a path without fragmentation and excluding the frame size.?
H. A process whereby routers learn about all of the devices on their networks. On IPv4 networks, this process is managed by ARP with help from ICMP. On IPv6 networks, NDP (Neighbor Discovery Protocol) automatically detects neighboring devices and automatically adjusts when nodes fail or are removed from the network.?
I. ?A repeated trial message transmitted by the tracert and traceroute utilities to trigger routers along a route to return specific information about the route.
J. ?Properties of a route used by routing protocols to determine the best path to a destination when various paths are available. Routing metrics may be calculated using any of several variables, including hop count, bandwidth, delay, MTU, cost, and reliability.

A. ?administrative distance 
B. autonomous system number?
C. ?gateway of last resort
D. gateway router?
E. ?interior router
F. latency?
G. ?MTU (maximum transmission unit)
H. neighbor discovery?
I. ?probe
J. routing metric
