provide a specific design for communication on the Internet

IP stands for

Internet Protocol

The physical or logical arrangement of a network is called the

topology

What typically happens at the bottommost layer of the OSI model

the wire or air are used to transmit electromagnetic waves

A unique address identifying a device is known as a

MAC address

The most secure WiFi encryption is

WPA2

A hospital implements a wireless network for medical devices. Which combination of characteristics is most critical for this application

Which is NOT an advantage of packet switching on the internet

security of the data sent

Which of the following does NOT describe a VPN network

separates broadcast traffic

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

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

Which of the following is an example of a PAN

Bluetooth

Packet switching is

breaking data into small blocks for transmission

Which of the following is a downside of VPN

work-life balance of employees

Why are international standards essential in network construction

they enable devices from different manufacturers to communicate using a common protocol

Which of the following CANNOT cause data speeds to slow on a network

other users compressing data being sent

Which is an example of a correct order in which to connect devices to access the Internet

Computer, Router, Modem, Internet

When is VPN NOT used

to connect sites on a LAN

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

OSI stands for

Open System Interconnection

What typically happens at the topmost layer of the OSI model

applications generate or respond to requests

The fastest transmission media is

fiber

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

TCP stands for

Transmission/Transport Control Protocol

Which of the following describes an extranet

allows a company to share some applications and web pages outside of its LAN

A network packet typically does NOT contain

information about the type of document being sent

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

Which of the following is NOT a valid network type

BAN

Which of the following is NOT a rule that may be included in a networking protocol

the organization of layers in the OSI model

Which of the following is true of a LAN

constrained to a small area

Which of the following is the best definition for the Internet

a network of networks

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

Which of the following is a characteristic of a P2P network

network devices connect directly to each other

Which of the following is NOT a benefit of VPN

faster network traffic between sites

Routers typically do NOT provide

control over compression

How are bandwidth and throughput related

the value of bandwidth is higher than throughput

Which protocol is typically used for video conferencing and gaming

UDP

Typically, in WiFi communications, lower frequencies provide higher bandwidth

false

Lossy compression can cause

higher bandwidth in a shared network

Wireless networking can typically be

cheaper than wired networking

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

The most reliable transmission media is

fiber

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

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

Which of the following is NOT a part of a VPN solution

LAN connection between end points

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

Which of the following is NOT true of the World Wide Web

it's also known as the internet

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

Which of the following are tasks NOT performed by a server

editing data

Which of the following is NOT a network topology

square
