ISC2 Certified in Cybersecurity (CC)Network SecurityEasy
A small office is setting up its first network and wants to ensure that all internal devices can communicate with each other and with the internet securely. They are on a limited budget and need a device that can manage network traffic, assign IP addresses, and provide basic firewall capabilities. Which network device would best meet these requirements?
- AWireless Router
- BHub
- CRepeater
- DModem
Show answer & explanationAnswer & explanation
Correct answer: A. Wireless Router
A wireless router combines the functions of a router (traffic management, IP assignment via DHCP), a switch (connecting multiple devices), and often a basic firewall, making it ideal for a small office with internet connectivity needs.
Why the other options are wrong
- B. A hub simply broadcasts data to all connected devices and offers no security or IP management.
- C. A repeater extends Wi-Fi range but does not provide routing, IP assignment, or firewall functions.
- D. A modem connects the network to the ISP but does not manage internal network traffic or security.
Wireless Router
A network device that combines the functions of a router, a switch, a wireless access point, and often a basic firewall to connect multiple devices to a local network and the internet.
- Connects local devices to the internet.
- Assigns IP addresses using DHCP.
- Provides Wi-Fi connectivity.
- Often includes basic firewall features.
Memory trick: The router is the 'Swiss Army Knife' for a small office network.
