What else can I help you with?
What are true statements about routes and their use?
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> 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.
Can a packet be forwarded without a route?
No packet can be forwarded without a route. Whether the packet is originating in a host or being forwarded by an intermediary device, the device must have a route to identify where to forward the packet.
What action is taken by a host on an Ethernet network when the host attempts to contact a remote host on another network?
The packet is sent using the IP address and MAC address of the default gateway.
Why does wireshark shows the actual MAC address for the local host but not for the remote host?
Wireshark displays the actual MAC address of the local host because it is directly connected to the network and can access its own hardware address. In contrast, for remote hosts, Wireshark typically shows the MAC address of the last device that forwarded the packet, such as a router, instead of the actual MAC address of the remote host. This is due to the way Ethernet and IP networking function, where MAC addresses are only visible within the same local network segment.
A subnet mask separates?
A submask is designed to separate the network id portion of an IP address from the host or client portion. This helps a router determine whether the packet needs to be forwarded to another network.
How will a packet that is sent from host A to host B be handled by the devices on the network?
C
How does ANDing help an originating host?
An originating host must determine if a packet should be sent directly to a host in the local network or be directed to the gateway.
What does the local host use to determine the destination network ID of a particular packet?
the address Class
When a host on network A sends a message to a host on network B which address does the router look at?
When a host on network A sends a message to a host on network B, the router looks at the destination IP address in the packet’s header to determine where to forward the message. This IP address is used to identify the specific network and host within that network. The router uses its routing table to decide the best path for the packet based on this destination IP address. The MAC address is not used for routing between different networks, as it only applies to the local network segment.
Why Network virtual terminal is needed in remote login?
Network Virtual Terminal, is a software version of a physical terminal and allows a user to log on to a remote host .So the application created emulation of terminal at the remote host .Users computer talks to the software terminal which in turn talks to the host & vice verse .Remote host believes it is communication with one of its own terminals and allow you to log on
Why do routers use anding?
ANDing is used by a router, to see if the host which has to be contacted, is on the local network of the router, or a remote network.
Why does a network host need to broadcast an ARP request?
A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message. Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.
