that the most efficient path actually goes through additional routers. Each router running OSPF maintains a database of the other routers' links. If OSPF learns of the failure of a given link, the router can rapidly compute an alternate path. This calculation demands more memory and CPU power than RIP would, but it keeps network bandwidth to a minimum and provides a very fast convergence time, often invisible to users. The algorithms used by link-state protocols and their faster convergence time also prevent routing loops. OSPF is supported by all modern routers. Therefore, it is commonly used on autonomous systems that rely on a mix of routers from different manufacturers. Describe the difference between dynamic ARP table entries and static ARP table entries. An ARP table can contain two types of entries: dynamic and static. Dynamic ARP table entries are created when a client makes an ARP request that could not be satisfied by data already in the ARP table. Static ARP table entries are those that someone has entered manually using the ARP utility. ICMP (Internet Control Message Protocol) is a _______ layer core protocol that reports on the success or failure of data delivery. Network Layer IP is an unreliable, connectionless protocol. True IPv4 and IPv6 use the same packet format. False
In IPv6, what field is used to indicate what sequence of packets from one source to one or multiple destinations a packet belongs to? Flow Label In a TCP segment, what field indicates how many bytes the sender can issue to a receiver while acknowledgement for the segment is outstanding? Sliding window List some examples of routing metrics that might be used to determine the best path for data. Routing metrics-Hop count, throrectical bandwidtth and actual throughpout on a potential path, Delay, or latency, on a potential path, which results in slower performance, load or the traffic or processing burden sustained by a router in the path. On IPv4 networks, IGMP operates at the Network layer of the OSI model to manage multicasting. True
