- VLAN
- WPA2
- Port Forwarding
Answer: VLAN (Virtual Local Area Network) separates network traffic for better security and management.
Question 7: Slow Ethernet Connection
A technician troubleshoots a slow Ethernet connection (200 Mbps) on a gigabit switch. What’s the likely issue?
- Weak Wi-Fi Signal
- Slow GPU
- Faulty Sound Driver
- Defective Printer Cable
- Using Cat 5 Cable
Answer: Cat 5 Cable only supports up to 100 Mbps; Cat 5e or higher is needed for gigabit speeds.
Question 8: Wireless Security Protocol
A technician is setting up a home router. Which wireless security protocol should be avoided due to vulnerabilities?
- WEP
- WPA3
- WPA2
- AES
- TKIP
Answer: WEP is outdated and easily cracked, making it insecure for modern networks.
Question 9: Testing Network Speed
A technician needs to test the speed of a wired network connection. What Windows command should they use?
- Speed Test
- Ping
- ipconfig
- netstat
- tracert
Answer: Speed Test measures network speed.
Question 10: Extending Ethernet
A network administrator needs to extend a high-speed Ethernet connection beyond 100m. What’s the best solution?
- Fiber Optic Cable
- Cat 7 Cable
- Wireless Bridge
- Coaxial Cable
- Flat Ethernet Cable
Answer: Fiber Optic Cable supports high-speed connections over long distances without signal degradation.
Question 11: Blocking Devices on Router
A technician wants to prevent specific devices from accessing the network. What should they enable?
- QoS Settings
- MAC Filtering
- Port Forwarding
- DHCP Reservation
- Wi-Fi 6
Answer: MAC Filtering allows administrators to specify which devices can connect to the network.
Question 12: Wi-Fi 6 Frequency Bands
A technician is installing a Wi-Fi 6 access point. Which frequency bands will it operate on?
- 5 GHz Only
- 2.4 GHz Only
- 2.4 GHz, 5 GHz, and 6 GHz
- 1.8 GHz and 3 GHz
- 900 MHz and 1.2 GHz
Answer: Wi-Fi 6E operates on 2.4 GHz, 5 GHz, and 6 GHz bands.
Question 13: Ethernet Connector
What type of connector is used for standard Ethernet cables?
- RJ11
- RJ45
- USB-C

A user reports frequent network drops with an Ethernet cable. What’s the most likely cause?
- Slow Monitor Refresh Rate
- Weak Wi-Fi Signal
- Outdated Sound Driver
- Low Laptop Battery
- Damaged Cable
Answer: A damaged Ethernet cable can cause intermittent network disconnections.
Question 15: Gigabit Ethernet Cable
A technician is setting up a gigabit internet connection. What’s the minimum cable category required?
- Cat 5e
- Cat 3
- Cat 5
- Cat 6a
- Cat 7
Answer: Cat 5e supports gigabit Ethernet (1 Gbps) over standard distances.

What’s the maximum length for a standard Ethernet cable before signal degradation occurs?
- 50m
- 100m
- 200m
- 75m
- 500m
Answer: 100m (328 ft) is the maximum length for Ethernet cables before a repeater is needed.
