-routing packets toward the destination -encapsulating PDUs from the transport layer

What are 2 services provided by the OSI network layer?

efficient packet handling

What is one advantage that the IPv6 simplified header offers over IPv4?

create a new layer 2 ethernet frame to be sent to the destination

A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the gigabit 0/1 interface. what will the router do next?

They have to keep their own local routing table that contains a route to the loopback interface, a local network route, and a remote default route.

How do hosts ensure that their packets are directed to the correct network destination?

127.0.0.1

What IPv4 reserved address is used for loop back?

flow label

When transporting data from real-time

Destination IP address

Which information is used by routers to forward a data packet toward its destination?

any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.

Why is NAT not needed in IPv6?

The default gateway address is used to forward packets originating from the switch to remote networks.

Within a production network, what is the purpose of configuring a switch with a default gateway address?

The computer has an invalid default gateway address

a computer can't access devices on other networks. What is the probable cause of this problem?

the packet will be sent directly to the destination host

a computer has to send a packet to a destination host in the same LAN, How will the packet be sent?

protocol

what IPv4 header field identifies the upper layer protocol carried in the packet.

the TCP/IP stack on the device is working correctly

what information does the loopback test provide?

connectionless

what is a basic characteristic of the IP protocol?

remote routes

what routing table entry has a next hop address associated with a destination network?

Time to Live (TTL)

which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?

the lower metric value that is associated with the destination network

which parameter does the route use to choose the path to the destination when there are multiple routes available?

IP relies on upper layer services to handle situations of missing or out-of-order packets.

which statement describes a feature of the IP protocol.
