What is the purpose of a default gateway?physically connects a computer to a networkprovides a permanent address to a computeridentifies the network to which a computer is connectedidentifies the logical address of a networked computer and uniquely identifies it tothe rest of the networkidentifies the device that allows local network computers to communicate withdevices on other networks9.
What type of routing uses information that is manually entered into therouting table?dynamicinteriorstaticstandard10. When the destination network is not listed in the routing table of aCisco router, what are two possible actions that the router might take?(Choose two.)The router sends an ARP request to determine the required next hop address.The router discards the packet.The router forwards the packet toward the next hop indicated in the ARP table.The router forwards the packet to the interface indicated by the source address.The router forwards the packet out the interface indicated by the default route entry.11.
What are the key factors to consider when grouping hosts into acommon network? (Choose three.)gatewayspurposephysical addressingsoftware versiongeographic locationownership12. What is a component of a routing table entry?the MAC address of the interface of the routerthe destination Layer 4 port numberthe destination host addressthe next-hop address13.

Which three statements are true about routes and their use? (Choosethree.)If no route to the destination network is found, the packet is returned to the previousrouter.If the destination network is directly connected, the router forwards the packet tothe destination host.If multiple network entries exist for the destination network, the most general routeis used to forward the packet.If no route exists for the destination network and a default route is present, thepacket is forwarded to the next-hop router.If the originating host has a default gateway configured, the packet for a remotenetwork can be forwarded using that route.If a host does not have a route manually configured for the destination network, thehost will drop the packet.17.

(Choose two.)require no device configurationprovide routers with up-to-date routing tablesrequire less processing power than static routes requireconsume bandwidth to exchange route informationprevent manual configuration and maintenance of the routing table21. What statement describes the purpose of a default route?A host uses a default route to transfer data to another host on the same networksegment.A host uses a default route to forward data to the local switch as the next hop to alldestinations.A host uses a default route to identify the Layer 2 address of an end device on thelocal network.A host uses a default route to transfer data to a host outside the local network whenno other route to the destination exists.comments (1)TOP04:07CCNA 1:Module 4POSTED BY ADMINСтр.
