2 Self-Test
True - ANS-The FCS includes a cyclic redundancy check (CRC) that the receiving NIC uses to
verify that the data being sent is correct.
True - ANS-The Open Systems Interconnection (OSI) model works for almost every type of
network, even extremely old and long-obsolete ones.
False - ANS-In a wired network, a charge on a wire represents a zero while no charge
represents a one.
False - ANS-When a frame arrives at the switch, the switch makes an exact copy of the frame
and sends it to every other system on the network.
True - ANS-The Link layer of the TCP/IP model maps to the top three layers of the OSI model.
True - ANS-No two systems on the same network share the same IP address.
True - ANS-When the NIC sends a frame that contains the broadcast address, every NIC on the
network processes that frame.
False - ANS-Two systems on the same network may have NICs with the same MAC address.
True - ANS-The Transport layer of the TCP/IP model uses both connection-oriented and
connectionless protocols.
False - ANS-A NIC reads the data portion of a frame to determine the address of the receiving
system.
False - ANS-The Network Interface layer of the TCP/IP model maps to the Network layer of the
OSI model.
True - ANS-Cabling, hubs, physical addresses, and NICs are included in the Link layer of the
TCP/IP model.
False - ANS-The TCP/IP model consists of six layers.
True - ANS-A network protocol is special software that allows a network to use logical
addressing in order to move data from one subnet to another.
