Question options: IPv1 IPv4 IPv6 IPv5 ion 29 0 / 1 point 34Which layers of the OSI model are all routers able to interpret? Question options: 1 2 3 4 ion 30 1 / 1 point What two fields below are used by IPv4 and IPv6 respectively to limit the number of times that a packet can be forwarded on a network?
Question options: hop limit TTL max path count total time routing ion 31 1 / 1 point Match each correct item with the statement below. _ 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. The delay between the transmission of a signal and its receipt. 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 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. 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. A repeated trial message transmitted by the tracert and traceroute utilities to trigger routers along a route to return specific information about the route. A router that directs data between networks within the same autonomous system. The largest IP packet size in bytes allowable by routers in a path without fragmentation and excluding the frame size. A router that connects an autonomous system with an outside network—for example, the router 1 . administrative distance 2 . autonomous system number 3 . gateway of last resort 4 . gateway router 5 . interior router 6 . latency 7 . MTU (maximum transmission unit) 8 . neighbor discovery 9 . probe 10 . routing metric
that connects a business to its ISP. _ The router on a network that accepts all unroutable messages from other routers. ion 32 1 / 1 point The receiving host de-encapsulates the message at each layer in _______ order and then presents the payload to the receiving application.
