2
What are three ways that bandwidth is
commonly measured?
• kbps
• Mbps
• Gbps
3
What are typical features that determine
throughput?
• network topology
• number of users on the network

• HTTP
5
Which of the following are data link layer
encapsulation details? (Choose two.)
•
•
•
•
Packets are put into frames.
Data is packaged into a packet.
Data is segmented into segments.
Data is converted for Internet
travel.
• An address is added to identify the
directly connected device.
6

that are geographically separated?
• router
7
Which of the following is the
Layer 4 PDU?
•
•
•
•
bit
frame
packet
segment
8
What is important to remember about the data
link layer of the OSI model when considering
Peer to Peer communication? (Choose three.)
•
•
•
•
It links data to the transport layer.
It encapsulates frames into packets.
It provides a service to the network layer.
It encapsulates the network layer information
into a frame.
• Its header contains a physical address which
is required to complete the data link
functions.
• It encodes the data link frame into a pattern of
1s and 0s (bits) for transmission on the
medium.
9
Which of the following is true regarding
network bandwidth?
•
•
•
•
Bandwidth is free.
Bandwidth has capacity limits.
Bandwidth never increases.
Bandwidth is not a key factor in
analyzing network performance.
10
What is the official name for the address
assigned to each network interface card
(NIC) by its manufacturer?
• MAC address
11
Which physical network topology uses a single
backbone cable and connects all hosts
directly to this cable?
• bus
12
What are the layers of the TCP/IP model?
•
•
•
•
network
internet
transport
application
Nebraska Is Totally Awesome
13
Which OSI and TCP/IP layer appears in
both models yet has different
functions in each?
• application
14
What two topologies are
considered logical
topologies?
• Token-passing
• broadcast
15
During the data encapsulation
process, how is the data broken
down by the transport layer?
• segments
16
In what 2 ways would you
describe a LAN?
• operates within a limited
geographical area
• connects physically adjacent
devices
17
Intranet, extranet and access are
considered valid types of
_____?
• VPNs
18
What physical topology connects all
cables to a central point of
concentration?
• star
19
What is the maximum possible throughput
obtained end to end on this network when the
user on Lab A communicates with the user on
LAB D?
• The maximum possible throughput is based on the
largest connection, the T3.
• The maximum possible throughput is based on the
smallest connection, the T1.
• There is not enough data to determine the maximum
possible throughput.
• The maximum possible throughput is the T1 plus T3
speed divided by 2.
20

Layer 1 PDU?
• bit
21
Which layer of the TCP/IP model
encapsulates TCP segments into
packets?
• internet
22
Which layer of the TCP/IP model
deals with quality-of-service
issues such as reliability, flow
control, and acknowledgement?
• transport
23
What data packaging type is created
at the data link layer during the data
encapsulation process?

packaging type that is created at the
data link layer during the data
encapsulation process.
1. Segments
2. Bits
3. Packets
4. Data
5. Frames
