01. When the destination network is not listed in the routing table of a Cisco 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 addres;
- 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.
- gateways;
- purpose ;
- physical addressing ;
- software version ;
- geographic location ;
- ownership .
- the MAC address of the interface of the router;
- the destination Layer 4 port number;
- the destination host address;
- the next-hop address.
- If no route to the destination network is found, the packet is returned to the previous router;
- If the destination network is directly connected, the router forwards the packet to the destination host;
- If multiple network entries exist for the destination network, the most general route is used to forward the packet;
- If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router;
- If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route;
- If a host does not have a route manually configured for the destination network, the host will drop the packet
- Replace S2 with a router;
- Place all servers on S1;
- Disable TCP/IP broadcasts;
- Subnet the 192.168.0.0 /24 network;
- Disable all unused interfaces on the switches.
- require no device configuration;
- provide routers with up-to-date routing tables;
- require less processing power than static routes require;
- consume bandwidth to exchange route information;
- prevent manual configuration and maintenance of the routing table
- A host uses a default route to transfer data to another host on the same network segment;
- A host uses a default route to forward data to the local switch as the next hop to all destinations;
- A host uses a default route to identify the Layer 2 address of an end device on the local network;
- A host uses a default route to transfer data to a host outside the local network when no other route to the destination exists.
- source and destination MAC;
- source and destination application protocol;
- source and destination port number;
- source and destination IP address .
- The destination is contacted before a packet is sent;
- The destination is not contacted before a packet is sent;
- The destination sends an acknowledgement to the source that indicates the packet was received;
- The destination sends an acknowledgement to the source that requests the next packet to be sent.
- type-of-service;
- identification;
- flags;
- time-to-live ;
- header checksum .
- dynamic;
- interior;
- static;
- standard .
- too few broadcasts;
- performance degradation;
- security issues;
- limited management responsibility;
- host identification;
- protocol compatibility.
- router;
- hub;
- switch;
- firewall;
- access point;
- bridge.
- destination network addres;
- source network address;
- source MAC address;
- well known port destination address.

- host portion;
- broadcast address;
- network portion;
- gateway address.
- physically connects a computer to a network;
- provides a permanent address to a computer;
- identifies the network to which a computer is connected;
- identifies the logical address of a networked computer and uniquely identifies it to the rest of the network;
- identifies the device that allows local network computers to communicate with devices on other networks.
- The host is unable to communicate on the local network;
- The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks;
- The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network;
- There is no impact on communications.
