Module 8-10 Review Exam Questions With
Correct Answers
A computer can access devices on the same network but cannot access devices on other
networks. What is the probable cause of this problem? - answer✔✔The computer has an invalid
default gateway address.
A feature of the IP protocol - answer✔✔IP relies on upper layer services to handle situations of
missing or out-of-order packets.
Why is NAT not needed in IPv6? - answer✔✔Any host or user can get a public IPv6 network
address because the number of available IPv6 addresses is extremely large.
Which parameter does the router use to choose the path to the destination when there are
multiple routes available? - answer✔✔the lower metric value that is associated with the
destination network
What are two services provided by the OSI network layer? - answer✔✔Routing packets toward
the destination
Encapsulating PDUs from the transport layer
Within a production network, what is the purpose of configuring a switch with a default gateway
address? - answer✔✔The default gateway address is used to forward packets originating from
the switch to remote networks.
What is a basic characteristic of the IP protocol? - answer✔✔connectionless
Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly? -
answer✔✔Time-to-Live (TTL)
What is one advantage that the IPv6 simplified header offers over IPv4? - answer✔✔efficient
packet handling
What IPv4 header field identifies the upper layer protocol carried in the packet? -
answer✔✔Protocol
What information does the loopback test provide? - answer✔✔The TCP/IP stack on the device is
working correctly.
What routing table entry has a next hop address associated with a destination network? -
answer✔✔remote routes

, How do hosts ensure that their packets are directed to the correct network destination? -
answer✔✔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.
When transporting data from real-time applications, such as streaming audio and video, which
field in the IPv6 header can be used to inform the routers and switches to maintain the same path
for the packets in the same conversation? - answer✔✔Flow Label
Which term describes a field in the IPv4 packet header used to identify the next level protocol? -
answer✔✔protocol
Which term describes a field in the IPv4 packet header that contains an 8-bit binary value used to
determine the priority of each packet? - answer✔✔differentiated services
Which term describes a field in the IPv4 packet header that contains a 32-bit binary value
associated with an interface on the sending device? - answer✔✔source IPv4 address
Which term describes a field in the IPv4 packet header used to detect corruption in the IPv4
header? - answer✔✔header checksum
Which term describes a field in the IPv4 packet header that contains a unicast, multicast, or
broadcast address? - answer✔✔destination IPv4 address
Which term describes a field in the IPv4 packet header used to limit the lifetime of a packet? -
answer✔✔TTL
Which term describes a field in the IPv4 packet header that contains a 4-bit binary value set to
0100? - answer✔✔version
What statement describes the function of the Address Resolution Protocol? - answer✔✔ARP is
used to discover the MAC address of any host on the local network.
Under which two circumstances will a switch flood a frame out of every port except the port that
the frame was received on? - answer✔✔The frame has the broadcast address as the destination
address.
The destination address is unknown to the switch.
Which statement describes the treatment of ARP requests on the local link? - answer✔✔They are
received and processed by every device on the local network.
Which destination address is used in an ARP request frame? - answer✔✔FFFF.FFFF.FFFF
A network technician issues the arp -d * command on a PC after the router that is connected to
the LAN is reconfigured. What is the result after this command is issued? - answer✔✔The ARP
cache is cleared.
