a. Protocol

What IPv4 header field identifies the upper layer protocol carried in the packet? a. Protocol b. Identification c. Version d. Differentiated Services

a. does not require a dedicated end-to-end connection b. operates independently of the network media

What are two characteristics of IP? (Choose two.) a. does not require a dedicated end-to-end connection b. operates independently of the network media c. retransmits packets if errors occur d. re-assembles out of order packets into the correct order at the receiver end e. guarantees delivery of packets

d. efficient packet handling

What is one advantage that the IPv6 simplified header offers over IPv4? a. smaller-sized header b. little requirement for processing checksums c. smaller-sized source and destination IP addresses d. efficient packet handling

b. to contain the commands that are used to initially configure a router on startup

What is the purpose of the startup configuration file on a Cisco router? a. to facilitate the basic operation of the hardware components of a device b. to contain the commands that are used to initially configure a router on startup c. to contain the configuration commands that the router IOS is currently using d. to provide a limited backup version of the IOS, in case the router cannot load the full featured IOS

c. remote routes

What routing table entry has a next hop address associated with a destination network? a. directly-connected routes b. local routes c. remote routes d. C and L source routes

c. directly connected route

What type of route is indicated by the code C in an IPv4 routing table on a Cisco router? a. static route b. default route c. directly connected route d. dynamic route that is learned through EIGRP

b. Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary? a. Connectionless acknowledgements are used to request retransmission. b. Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host. c. Network layer IP protocols manage the communication sessions if connection-oriented transport services are not available. d. The best-effort delivery process guarantees that all packets that are sent are received.

b. The IPv6 header is simpler than the IPv4 header is, which improves packet handling.

Which characteristic describes an IPv6 enhancement over IPv4? a. IPv6 addresses are based on 128-bit flat addressing as opposed to IPv4 which is based on 32-bit hierarchical addressing. b. The IPv6 header is simpler than the IPv4 header is, which improves packet handling. c. Both IPv4 and IPv6 support authentication, but only IPv6 supports privacy capabilities. d. The IPv6 address space is four times bigger than the IPv4 address space.

c. the ability to operate without regard to the data that is carried in each packet

Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts? a. the de-encapsulation of headers from lower layers b. the selection of paths for and direct packets toward the destination c. the ability to operate without regard to the data that is carried in each packet d. the ability to manage the data transport between processes running on hosts
