4.7.4 Module Quiz - Physical Layer
Answers
1. Which standards organization oversees development of
wireless LAN standards?
. IANA
• IEEE
. IOS
< TIA
Explanation: IANA oversees the management of IP
address allocation and domain names. ISO is the largest
developer of international networking standards and is
famous for the Open Systems Interconnection (OSI) model.
TIA focuses on communication standards. The IEEE 802
standards are many, but the ones that affect an entry-level
network professional are Ethernet (802.3), wireless LANs
(802.11), and wireless PANs (802.15).
2, A network administrator is designing a new network
infrastructure that includes both wired and wireless
connectivity. Under which situation would a wireless
connection be recommended?

A D
The end-user device
The end-user device
because of performance requirements.
• The end-user device needs mobility when connecting
to the network. A D
• The end-user device area has a high concentration of RFI.
Explanation: When the end-user devices need mobility to
connect to the network, wireless is recommended. If an
end-user device only has an Ethernet NIC, the user will
only be able to use Ethernet cabling. If RFI is an issue,
wireless is not recommended. An end-user device that
requires a dedicated connection for performance would
perform better with a dedicated Ethernet cable.
3. A network administrator is troubleshooting connectivity
issues on a server. Using a tester, the administrator notices
that the signals generated by the server NIC are distorted
and not usable. In which layer of the OSI model is the error
categorized?
• presentation layer
• network layer
• physical layer
• data link layer
Explanation: The NIC has responsibilities in both Layer 1
and Layer 2. The NIC encodes the frame as a series of
signals that are transmitted onto the local media. This is the
responsibility of the physical layer of the OSI model. The
signal could be in the form of electrical, optical, or radio
waves.

5. Which type of UTP cable is used to connect a PC to a
switch port?
. console
* rollover
a crossover
. straight-through
Explanation: A rollover cable is a Cisco proprietary cable
used to connect to a router or switch console port. A
straight-through (also called patch) cable is usually used to
interconnect a host to a switch and a switch to a router. A
crossover cable is used to interconnect similar devices
together, for example, between two switches, two routers,
and two hosts.
6. What is the definition of bandwidth?
• the measure of the transfer of bits across the media over a
given period of time
• the speed at which bits travel on the network
• the amount of data that can flow from one place to
another in a given amount of time
- the measure of usable data transferred over a given period
of time
