Module 5 Review
Which layer of the OSI model
covers physical media?
• Layer 1
2
Which of the following companies
are responsible for creating and
implementing the first Ethernet LAN
specifications? (Choose three.)
•
•
•
•
•
•
Intel
Digital
Microsoft
Hewlett Packard
Xerox
Cisco
3
Which type of connector supports
100BASE-T Ethernet over
Category 5e UTP?
• RJ-45
4
In which of the following
situations would a straightthrough cable be used?
•
•
•
•
•
•
Note:
switch to PC
router to router
router to switch
router to PC
switch to hub
PC to hub
Count the crossover connections.
You need an odd number of crossover
connections in order to have
communication.
If you have an odd number of
crossover connections to start with,
then you use a straight-through cable.
A PC NIC has a straight-through port.
A hub has crossover ports, except for
the daisy-chain port. A switch has
crossover ports. A router has straight5
through ports.
What are the reasons for the Four
Repeater Rule of 10 Mbps Ethernet?
(Name two.)
• to prevent late collisions
• to limit latency
6
What are 2 major benefits of
wireless networks when compared
to wired networks?
• mobility
• no need to run cables to hosts
7
What are 3 types of hubs?
• active
• passive
• Intelligent
8
What are 2 other
names for a hub?
• concentrator
• multiport repeater
9
What are 3 benefits of peer-topeer networks?
• easy to create
• no centralized equipment
required
• centralized administrator not
required
10
What are 3 advantages of
client/server networks?
• centralized security
• centralized backups
• enhanced network services
11
What is the recommended maximum
number of workstations configured
on a peer-to-peer network?
• 10
12
What are the two basic
functions of a switch?
• switching data frames
• build and maintain tables
13
What must be connected to the
DB-15 AUI port to provide
connectivity for an RJ-45
terminated cable?
• transceiver
14
At which layer of the OSI
model is a NIC classified?
• Data link
15
Which protocol is typically
used to carry data over an
ISDN B channel?
• PPP
16
An ISDN BRI connection is
composed of how many
bearer channels?
•2
Remember the 2B+D rule:
2 bearer channels for voice and
data and 1 D channel for
signaling to carry instructions
17

with a modem to make
configuration changes?

clocking for WAN serial
transmission?
• DCE
• CSU/DSU
20
Which address does a bridge
use to make filtering and
switching decisions?
• destination MAC
21
What are 2 technologies
used in wireless data
transmission?
• IR
– Infrared
• RF
– Radio Frequency
22
In a UTP crossover cable,
which 2 pairs of pins are
crossed?
• 1 and 2
• 3 and 6
23
Which layer of the OSI model
addresses cable and
connector type?
