provide a specific design for communication on the Internet
2
New cards
IP stands for
Internet Protocol
3
New cards
The physical or logical arrangement of a network is called the
topology
4
New cards
What typically happens at the bottommost layer of the OSI model
the wire or air are used to transmit electromagnetic waves
5
New cards
A unique address identifying a device is known as a
MAC address
6
New cards
The most secure WiFi encryption is
WPA2
7
New cards
A hospital implements a wireless network for medical devices. Which combination of characteristics is most critical for this application
high reliability, strong security, and quality of service (QoS) to prioritize critical traffic
8
New cards
Which is NOT an advantage of packet switching on the internet
security of the data sent
9
New cards

Which of the following does NOT describe a VPN network

separates broadcast traffic

10
New cards
Which of the following is a benefit of the fault-tolerant nature of Internet routing
the ability to provide data transmission even when some connections between routers have failed
11
New cards
An organization allows employees to use personal devices (BYOD) on the corporate wireless network. Which security approach provides the best balance of security and usability
network segmentation with separate VLAN for personal devices, WPA3 encryption, and device authentication through certificates
12
New cards
Which of the following is an example of a PAN
Bluetooth
13
New cards
Packet switching is
breaking data into small blocks for transmission
14
New cards

Which of the following is a downside of VPN

work-life balance of employees

15
New cards
Why are international standards essential in network construction
they enable devices from different manufacturers to communicate using a common protocol
16
New cards
Which of the following CANNOT cause data speeds to slow on a network
other users compressing data being sent
17
New cards
Which is an example of a correct order in which to connect devices to access the Internet
Computer, Router, Modem, Internet
18
New cards
When is VPN NOT used
to connect sites on a LAN
19
New cards
A multinational corporation needs to connect offices in Tokyo, London, and New York while allowing business partners limited access to specific resources. Which combination of network types would be most appropriate
a WAN connecting the offices with an extranet for partner access
20
New cards
OSI stands for
Open System Interconnection
21
New cards
What typically happens at the topmost layer of the OSI model
applications generate or respond to requests
22
New cards
The fastest transmission media is
fiber
23
New cards
A streaming service needs to deliver 4K video content to users with varying internet speeds. Why is adaptive compression essential in this scenario
compression allows the service to adjust quality based on available bandwidth, preventing buffering while maximizing quality
24
New cards
TCP stands for
Transmission/Transport Control Protocol
25
New cards
Which of the following describes an extranet
allows a company to share some applications and web pages outside of its LAN
26
New cards
A network packet typically does NOT contain
information about the type of document being sent
27
New cards
When consistent data flow and minimal external interference are critical factors, which is a key advantage of a wired network over a wireless one
lower susceptibility to signal interference
28
New cards
Which of the following is NOT a valid network type
BAN
29
New cards
Which of the following is NOT a rule that may be included in a networking protocol
the organization of layers in the OSI model
30
New cards
Which of the following is true of a LAN
constrained to a small area
31
New cards
Which of the following is the best definition for the Internet
a network of networks
32
New cards
Which scenario best illustrates why flow control is necessary in network protocols
a fast server sending data to a slower client device that cannot process incoming packets quickly enough
33
New cards
Which of the following is a characteristic of a P2P network
network devices connect directly to each other
34
New cards
Which of the following is NOT a benefit of VPN
faster network traffic between sites
35
New cards
Routers typically do NOT provide
control over compression
36
New cards
How are bandwidth and throughput related
the value of bandwidth is higher than throughput
37
New cards
Which protocol is typically used for video conferencing and gaming
UDP
38
New cards
Typically, in WiFi communications, lower frequencies provide higher bandwidth
false
39
New cards
Lossy compression can cause
higher bandwidth in a shared network
40
New cards
Wireless networking can typically be
cheaper than wired networking
41
New cards
Which statement best describes the differences between transmission media
fiber optic cables provide high-speed and secure transmission but are more costly and harder to install
42
New cards
The most reliable transmission media is
fiber
43
New cards
A hospital implements VLANs to separate medical devices, administrative computers, and guest WiFi traffic on the same physical network infrastructure. What is the primary advantage of this approach compared to using separate physical LANs
VLANs reduce hardware costs and improve network management while maintaining logical separation
44
New cards
A user enters a Web address in a browser, and a request for a file is sent to a Web server. Which of the following best describes how the file is sent back to the user
the file is broken into packets and sent over a network, the packets must be reassembled by the user's computer when they are received, if any packets are missing the browser re-requests the missing packets
45
New cards
Which of the following is NOT a part of a VPN solution
LAN connection between end points
46
New cards
A packet traveling from Computer A to Computer B takes Route 1 through three routers, while another packet from the same transmission takes Route 2 through five routers. What does this scenario demonstrate about packet switching
packets can take different paths through the network, with routing decisions based on current network conditions
47
New cards
Which of the following is NOT true of the World Wide Web
it's also known as the internet
48
New cards
A school implements a wireless network covering the entire campus. Students report strong signals but slow speeds in the cafeteria during lunch, while other areas work well. What is the most likely cause
high device density in the cafeteria causes channel congestion and bandwidth sharing among many users
