What information is added during encapsulation at OSI Layer 3?
Source and destination MAC address.
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.
What was the reason for the creation and implementation of IPv6?
To relieve IPv4 address depletion
Which command can be used on a Windows host to display the routing table?
netstat -r
Which IPv4 address can a host use to ping the loopback interface?
127.0.0.1
When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination?
Destination IP address
Which information is used by routers to forward a data packet toward its destination?
Destination IP address
Which field in an IPv4 packet header will typically stay the same during its transmission?
Destination address
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.
Which characteristic describes an IPv6 enhancement over IPv4?
The IPv6 header is simpler, which improves packet handling.
How does the network layer use the MTU value?
The MTU is passed to the network layer by the data link layer
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 data received and can request transmission from the upper-level protocols on the sending host.
