How does the network layer use the MTU value?

The MTU is passed to the network layer by the data layer.

Which field in an IPv4 packet header will typically stay the same during its transmission?

Destination Address

What information is added during encapsulation at OSI Layer 3?

source and destination IP address.

What was the reason for the creation and implementation of IPv6?

to relieve IPv4 address depletion

Which characteristic describes an IPv6 enhancement over IPv4?​

The IPv6 header is simpler than the IPv4 header is, which improves packet handling.

When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination?

Which field in an IPv6 packet is used by the router to determine if a packet has expired and should be dropped?

Hop Limit

Which statement accurately describes a characteristic of IPv4?

IPv4 has a 32 bit address space

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

The packet will be sent directly to the destination host

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?

Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-layer protocols on the sending host.

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

destination IP address

Which command can be used on a Windows host to display the routing table?
