New Update
Which characteristic of the network layer in the OSI model allows carrying packets for
multiple types of communications among many hosts? - Answer ✔✔- the ability to
operate without regard to the data that is carried in each packet
What are two characteristics of IP? (Choose two.) - Answer ✔✔- does not require a
dedicated end-to-end connection
operates independently of the network media
When a connectionless protocol is in use at a lower layer of the OSI model, how is
missing data detected and retransmitted if necessary? - Answer ✔✔- Upper-layer
connection-oriented protocols keep track of the data received and can request
retransmission from the upper-level protocols on the sending host.
Which field in the IPv4 header is used to prevent a packet from traversing a network
endlessly? - Answer ✔✔- Time-to-Live
What IPv4 header field identifies the upper layer protocol carried in the packet? -
Answer ✔✔- Protocol
What is one advantage that the IPv6 simplified header offers over IPv4? - Answer ✔✔-
efficient packet handling
Refer to the exhibit. Which route from the PC1 routing table will be used to reach PC2?

Refer to the exhibit. R1 receives a packet destined for the IP address 192.168.2.10. Out
which interface will R1 forward the packet? - Answer ✔✔- Refer to the exhibit. R1
receives a packet destined for the IP address 192.168.2.10. Out which interface will R1
forward the packet?
What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?
- Answer ✔✔- directly connected route
What routing table entry has a next hop address associated with a destination network?
- Answer ✔✔- remote routes
