CompTIA A+ Certification Core 1 (220-1101) - Network Troubleshooting

The video tutorial covers troubleshooting wired networking issues for the A+ exam, focusing on no connectivity, limited connectivity, intermittent connectivity, and slow transfer speeds. It provides practical advice on checking physical connections, IP addressing, DHCP server issues, and using tools like ping and task manager. The tutorial also highlights the importance of understanding CompTIA exam questions and using QoS settings to manage network performance.

What is the first step to take when experiencing no connectivity in a wired network?

• Check the wireless settings

• Verify the physical connection

• Update the network drivers

• Restart the computer

What might cause limited connectivity in a network?

• A slow network card

• A rogue DHCP server

• A broken cable

• An outdated operating system

What is a common cause of intermittent connectivity in wired networks?

• Incorrect IP configuration

• Interference from nearby equipment

• Outdated network drivers

• A faulty router

What should you check if you suddenly cannot access a network folder you previously could?

• The network's DNS settings

• The router's firmware version

• The computer's firewall settings

• The folder's permissions

What tool can help identify processes consuming excessive network bandwidth?

• Device Manager

• Network Monitor

• Task Manager

• Event Viewer

How can QoS settings be useful in managing network performance?

• By increasing the network speed

• By prioritizing important traffic

• By reducing interference

• By blocking unwanted connections

What is a potential solution for slow transfer speeds in a wired network?

• Switching to a wireless network

• Using a different Ethernet cable

• Adjusting QoS settings

• Disabling the firewall
