DNS (Domain Name System) - translate a website name to an IP address. RARP (Reverse Address Resolution Protocol) – Dynamic routing protocols include the following except. (RARP, RIP, OSPF, EIGRP) Hub – which network device functions only at Layer 1 of the OSI model? (Hub, NIC, router, switch) A switch tracks MAC addresses of directly-connected devices – how does a switch differ from a hub? Application – which layer of the OSI provides a direct network services to a user? Hyperlink- what do you call an object, can be a picture, a word or phrase, on a web that when you click transfers you to a new webpage? Transport – assigning port numbers to segments of data is responsibility of what OSI layers? Network – where does routing occur within the TCP/IP reference model? -t – to initiate a ping, Click on “Start”, “Run” type in “Command” or Cmd. When a command prompt appears, type ping . In order to monitor the connection continuously, what command must be added to the latter? 48 – Data link layer is responsible for converting the logical identifier (IP address) to physical identifier which is the MAC address. How many bits does a MAC address has? MAC address of 0000.00aa.aaa will be added to the MAC address table/ The frame will be forwarded out fa0/1,fa0/2, and fa0/3. – the ports that are shown are the only active ports on the switch. The MAC address table is shown in its entirety. The Ethernet frame that is shown arrives at the switch. What “two” operations will the switch perform when it receives this frame? Application – what OSI layer is closest to the user? 16 – how many bits are used to represent a port number? Repeaters – what is the name of the network device whose function is simply takes the original signal from an input, amplifies it and deliver to an output? Switch look at routing table in making forwarding decision – advantages of switching over bridge are the following except?...
