Question 1

Which of the following devices is most likely owned and provided by the ISP?
A) Router
B) Modem
C) Switch
D) Hub

Accepted Answer

The modem is the device that connects a household or business to the internet service provided by the ISP. The ISP typically provides and owns the modem, as it is necessary for their service to function. Routers, switches, and hubs are networking devices that may be owned and provided by the user or the ISP depending on the specific circumstances.

Question 2

Kabir just bought a new wireless router and wants to make sure his network will be secure from other people using it without his permission.He's working on configuring security settings for the wireless network and is trying to think through all the settings that will help protect his network.What should Kabir configure so no one can change his network's settings?
A) WPA2 encryption
B) A router password

Question 5

Which network type is often used for vendor access?
A) Intranet
B) Intranet.
C) Extranet
D) Wireless network

Accepted Answer

Extranet is a network which allows controlled access to outside vendors, suppliers or customers. Intranet is an internal network used within a company or organization, while wireless network refers to a type of network that allows devices to connect without the use of physical cables. Therefore, the best choice for vendor access is an extranet.

Question 6

Tori is traveling for a business conference and needs to order a computer part so it will arrive at her hotel before her presentation at the end of the week.To do this,she'll need to enter her credit card number over the hotel's wireless network.How can Tori protect her financial information?
A) Choose a wireless network that uses the hotel's name
B) Make sure the website she orders from is secure
C) Use a VPN connection
D) Use a coffee shop's wireless network instead

Accepted Answer

Using a VPN connection will encrypt the traffic between Tori's device and the website she is using to order the computer part, making her financial information more secure. Choosing a wireless network that uses the hotel's name or using a coffee shop's wireless network does not provide any additional security. While it is important to make sure the website is secure, using a VPN connection adds an extra layer of protection.

Question 8

Aisha's boss asked her to order a new NAS device to provide network storage for their office.She knows she needs multiple hard drives for the device.What other feature is important to ensure high performance for this device?
A) High performance CPU
B) High bandwidth NIC
C) Extra RAM
D) An extra UPS

Accepted Answer

A high bandwidth NIC (Network Interface Card) will ensure fast data transfer speeds between the NAS device and the computers accessing the network storage. This is important to achieve high performance for the device. While having a high performance CPU and extra RAM may also contribute to performance, they are not as critical as a high bandwidth NIC for a NAS device. An extra UPS (Uninterruptible Power Supply) is important for protecting the device from power outages but does not directly impact performance.

Question 9

Rachelle is an office manager for an active real estate agency.She's overseeing a transition to a more complete reliance on electronic documents and needs a way to make dozens of files readily available to all office staff.What technology can she use to solve this problem?
A) VPN
B) PAN
C) NAS
D) WAN

Accepted Answer

Rachelle can use a NAS (Network Attached Storage) device to store all the electronic documents in one central location and make them easily accessible to all office staff. They can connect to the NAS through the office network and access the files as needed. A VPN (Virtual Private Network) is a secure way to access the office network from outside the office, but it wouldn't solve the problem of making files readily available to all office staff. A PAN (Personal Area Network) is a network for devices within a single person's workspace and wouldn't be helpful for this scenario. A WAN (Wide Area Network) is used for connecting devices and networks over large distances and wouldn't be necessary for a single office.

Question 10

Sonia works from home and uses the Internet often throughout the day.When they're home,Sonia's husband and children also use her network for gaming,social media,and streaming videos or music.What kind of network best describes Sonia's network?
A) ISP network
B) Business network
C) Internet
D) Home network

Accepted Answer

Sonia's network is a home network as it is used by her and her family at their residence. The other options don't fit as well - an ISP network typically refers to the network owned and managed by an Internet Service Provider, a business network usually refers to a network used within a company or organization, and "Internet" on its own doesn't really capture the fact that Sonia is using her own network at home.

Question 11

Tyler recently discovered that his neighbors have been using his wireless network to stream movies in the evening.This has caused slower network performance for Tyler,who likes to play Internet games after work.What can Tyler do to protect his wireless network from his neighbors?
A) Configure network authentication
B) Add a firewall to the network
C) Change the key on his door
D) Use a VPN

Accepted Answer

Tyler can configure network authentication, such as WPA2 or a stronger encryption method, to require a password to connect to the network. This will prevent unauthorized access to his network and improve performance for his own devices. Adding a firewall and using a VPN may also provide additional security, but they may not directly address the issue of neighbors using his network. Changing the key on his door is not relevant to protecting his wireless network.

Question 12

Mick's computer has been having trouble connecting to his wireless network.Sometimes it will connect and then loses the connection within a few minutes.Sometimes he can't get it to connect at all,even when the wireless router is just a few feet away from the computer.Mick's smartphone connects to the network fine,though.What network device most likely needs to be replaced?
A) NIC
B) Router
C) Ethernet cable
D) Modem

Accepted Answer

The NIC (Network Interface Card) in Mick's computer is most likely the issue, as it is responsible for connecting the computer to the network. Since Mick's smartphone connects without issue, the router, modem, and Ethernet cable (which wouldn't be used for wireless connections) are likely functioning correctly.

Question 13

When an ISP throttles,or slows down,one customer's very busy Internet activity so that other customers don't experience slower Internet service,what concept is being challenged?
A) Social engineering
B) Freedom of choice
C) Net neutrality
D) Network security

Accepted Answer

The concept being challenged in this scenario is net neutrality, which is the idea that all Internet traffic should be treated equally without any discrimination or preference given to certain types of traffic or users. Throttling one customer's Internet activity goes against the principles of net neutrality by giving priority to other customers and potentially limiting access to certain websites or services.

Question 14

Zeke is settling in at a coffee shop for some study time before his next class.He notices the coffee shop's wireless network is secured and not open.What information does he need to ask from the barista so he can access the wireless network and get onto the Internet?
A) User password
B) Rootkit
C) Firewall password
D) Security key

Accepted Answer

The information Zeke needs to ask for is the security key, also known as the network password or Wi-Fi password. This is the code that will allow him to access the secured wireless network and get onto the Internet. The user password is specific to an individual user's account and would not be necessary for accessing the network. A rootkit is a type of malicious software, and a firewall password would be used to access a network's firewall settings, not the wireless network itself.

Question 15

Sandhya is installing a security camera at the entrance to her office.The camera needs power and network access,but there's no power outlet near the door.What technology can Sandhya use to get power to the security camera?
A) Wi-Fi
B) PoE
C) TCP/IP
D) LTE

Accepted Answer

Sandhya can use Power over Ethernet (PoE) technology to power the security camera and provide network access through a single Ethernet cable. This would eliminate the need for a separate power outlet near the door. Wi-Fi, TCP/IP, and LTE technologies do not provide power to the camera.

Question 16

A) Her USB flash drive
B) The library's computer
C) A remote server
D) Her smartphone

Accepted Answer

The question specifically mentions that Liesel saves her file to the cloud, which typically refers to a remote server accessed via the internet. Options A, B, and D are all physical devices, while option C refers to a location for storing and accessing data. Therefore, the best choice is C, a remote server.

Question 17

What kind of cable is connected to a DSL modem on the ISP's side of the device?
A) TV cable
B) Ethernet cable
C) Telephone cable
D) Power cable

Accepted Answer

A DSL modem on the ISP's side is connected to a telephone cable. This is because DSL technology uses existing telephone lines to provide internet connectivity. A TV cable is used for cable internet, while an Ethernet cable is used for fiber optic and some cable internet connections. A power cable is required to power the DSL modem, but it is not the type of cable connected to the ISP's side.
