1. Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts?
· the de-encapsulation of headers from lower layers
· the selection of paths for and direct packets toward the destination
· the ability to operate without regard to the data that is carried in each packet
· the ability to manage the data transport between processes running on hosts
2. What are two characteristics of IP? (Choose two.)
· does not require a dedicated end-to-end connection
· operates independently of the network media
· retransmits packets if errors occur
· re-assembles out of order packets into the correct order at the receiver end
· guarantees delivery of packets
3. When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?
· Connectionless acknowledgements are used to request retransmission.
· Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.
· Network layer IP protocols manage the communication sessions if connection-oriented transport services are not available.
· The best-effort delivery process guarantees that all packets that are sent are received.
4. Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?
· Time-to-Live
· Sequence Number
· Acknowledgment Number
· Differentiated Services
5. What IPv4 header field identifies the upper layer protocol carried in the packet?
· Protocol
· Identification
· Version
· Differentiated Services
6. What is one advantage that the IPv6 simplified header offers over IPv4?
· smaller-sized header
· little requirement for processing checksums
· smaller-sized source and destination IP addresses
· efficient packet handling
7. Refer to the exhibit. Which route from the PC1 routing table will be used to reach PC2?
