introduction to networks 8-10
Which IPv4 address can a host use to ping the loop back interface
127.0.0.1
Why is NAT not needed in IPv6?
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.
Which statement describes a feature of the IP protocol
IP relies on upper layer services to handle situations of missing or out of order packets
What information does the loop back test provide
The TCP/IP stack on the device is working correctly
A computer can access devices on the same network but cannot access devices on other networks. What is the probable cause of this problem?
The computer has an invalid default gateway address.
Within a production network, what is the purpose of configuring a switch with a default gateway address?
The default gateway address is used to forward packets originating from the switch to remote networks.
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.
Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?
Time to Live
What is a basic characteristics of the IP protocol
connectjonless
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?
create the new Layer 2 ethernet frame to be sent to the destination
Which information is used by routers to forward a data packet to its destination
destination IP adress
What is one advantage that the IPv6 simplified header offers over IPv4
efficient packet handling
What IPv4 header field identifies the upper layer protocol carried in the packet?
protocol
What routing table entry has a next hop address associated with a destination network?
remote routes
What are two services provided by the OSI network layer
routing packets toward the destination encapsulating PDUs from the transport layer
Which parameter does the router use to choose the path to the destination when there are multiple router available
the lower metric value that is associated with the destination network
