Between Networks Exam ACTUAL
QUESTIONS AND CORRECT ANSWERS
What routing table entry has a next hop address associated with a destination network? - Correct
answers✔✔remote routes
What is one advantage that the IPv6 simplified header offers over IPv4? - Correct
answers✔✔efficient packet handling
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? - Correct answers✔✔Flow Label
What are two services provided by the OSI network layer? (Choose two.) - Correct
answers✔✔encapsulating PDUs from the transport layer
routing packets toward the destination
A computer can access devices on the same network but cannot access devices on other
networks. What is the probable cause of this problem? - Correct answers✔✔The computer has an
invalid default gateway address.
What is a basic characteristic of the IP protocol? - Correct answers✔✔connectionless
Which statement describes a feature of the IP protocol? - Correct answers✔✔IP relies on upper
layer services to handle situations of missing or out-of-order packets.
, Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly? -
Correct answers✔✔Time-to-Live
Which parameter does the router use to choose the path to the destination when there are
multiple routes available? - Correct answers✔✔the lower metric value that is associated with the
destination network
What are two potential network problems that can result from ARP operation? (Choose two.) -
Correct answers✔✔Network attackers could manipulate MAC address and IP address mappings
in ARP messages with the intent of intercepting network traffic.
On large networks with low bandwidth, multiple ARP broadcasts could cause data
communication delays.
What is the effect of using the Router# copy running-config startup-config command on a
router? - Correct answers✔✔The contents of NVRAM will change.
What will happen if the default gateway address is incorrectly configured on a host? - Correct
answers✔✔The host cannot communicate with hosts in other networks.
Refer to the exhibit. A user PC has successfully transmitted packets to www.cisco.com. Which IP
address does the user PC target in order to forward its data off the local network? - Correct
answers✔✔172.20.0.254
R1(config)# - Correct answers✔✔service password-encryption
R1> - Correct answers✔✔enable
