William is setting up a wireless network in his home and needs a device that will allow his wireless devices to connect to the network. What is an access point?

• A hub that accepts wireless clients through an analog wireless signal

• An electronic device that can be used to increase network connect beyond the standard range

• A device that modulates an analog carrier signal to encode digital information and demodulates the signal to decode the transmitted information

• A network device that connects two similar network segments together

Answer explanation

An access point is a hub that accepts wireless clients through an analog wireless signal, allowing devices to connect to a network wirelessly. This makes the first choice the correct definition.

Olivia is setting up her home internet and needs to understand what a modem is. What is a modem?

• A network device that connects all the segments of a network together in a star topology Ethernet network

• A network device used to connect multiple network segments together

• A device that modulates an analog carrier signal to encode digital information and demodulates the signal to decode the transmitted information

• A hub that accepts wireless clients through an analog wireless signal

Answer explanation

A modem is specifically designed to modulate and demodulate signals, allowing digital data to be transmitted over analog communication lines. This makes the correct choice the one that describes its function accurately.

Aria is setting up a home network and needs to connect multiple devices. Which layer device should she use?

• 1

• 2

• 3

• 4

Answer explanation

A switch operates at Layer 2 of the OSI model, which is the Data Link layer. It uses MAC addresses to forward data within a local network, distinguishing it from Layer 3 devices like routers that handle IP addresses.

Answer explanation

A media converter is a device that enables the conversion of one type of cabling to another, such as from fiber optic to copper, making it the correct choice for this question.

Liam is setting up a new office and needs to manage wireless network access points to allow wireless devices to connect to the network. Which of the following should he use?

• WLC

• LAN

• WLN controller

• WLAN database

Answer explanation

WLC, or Wireless LAN Controller, manages wireless access points, enabling wireless devices to connect to the network. It centralizes control and configuration of multiple access points, making it the correct choice.

In a busy online store managed by David, ______ efficiently distribute incoming network traffic across a group of backend servers.

Answer explanation

Load balancers efficiently distribute incoming network traffic across multiple backend servers, ensuring optimal resource use and improved response times.

Scarlett is trying to access a website, but her request first goes through a(n) ______, which acts as a gateway between her and the server hosting the website.

Answer explanation

A proxy server acts as an intermediary between a client and a server, handling requests and responses. It helps in managing traffic, enhancing security, and improving performance, making it the correct answer for the given question.

During a cybersecurity class, Isla asked if an IDS can drop malicious packets, offer malware protection, and reset the connection of source hosts.

• True

• False

Answer explanation

The statement is false because IDS (Intrusion Detection Systems) primarily monitor and alert on malicious activity but do not actively drop packets or reset connections; those functions are typically associated with IPS (Intrusion Prevention Systems).

In Liam's office, they recently upgraded their phone system. How do most phones in modern offices like Liam's differ from phone lines via the POTS?

• Office phones connect via analog phone line

• Office phones connect over IP

• There are no differences between the two

• Office phones only offer communication methods via Zoom

Answer explanation

Most modern office phones connect over IP (Internet Protocol), allowing for advanced features and integration with other digital services, unlike traditional POTS (Plain Old Telephone Service) which uses analog lines.
