What is the TCP/IP Protocol Suite?

• A type of computer software

• A programming language

• A set of protocols that allows computers to communicate over a network.

• A hardware component for network communication

Name three common network topologies.

• mesh

• tree

• point-to-point

• bus, star, ring

What are firewalls and intrusion detection systems used for?

• Network security

• Hardware maintenance

• Software development

• Data storage

How can you secure a wireless network?

• Disable encryption on the network

• Use a weak password for the network

• Follow the steps mentioned in the explanation.

• Broadcast the network name (SSID) to everyone

What are some common network troubleshooting techniques?

• Turning off the computer and turning it back on

• Blowing on the network cables to remove dust

• Checking network cables and connections, restarting network devices, checking network settings, running network diagnostics tools, and updating network drivers.

• Praying for a stable network connection

What are the layers of the TCP/IP Protocol Suite?

• Physical Layer, Data Link Layer, Network Layer, and Transport Layer

• Application Layer, Presentation Layer, Session Layer, and Transport Layer

• Network Layer, Data Link Layer, Transport Layer, and Application Layer

• Network Interface Layer, Internet Layer, Transport Layer, and Application Layer

What is a star network topology?

• A star network topology is a network configuration where all devices are connected to a central hub or switch.

• A star network topology is a network configuration where all devices are connected to a central hub or switch, but the hub or switch is not connected to any other device.

• A star network topology is a network configuration where all devices are connected to multiple central hubs or switches.

• A star network topology is a network configuration where all devices are connected to each other in a circular manner.

What is the purpose of a firewall?

• The purpose of a firewall is to block all incoming and outgoing network traffic.

• The purpose of a firewall is to slow down the network speed.

• The purpose of a firewall is to monitor and record all network activities.

• The purpose of a firewall is to protect a network from unauthorized access and potential threats.

What are some security measures for wireless networks?

• Using no passwords, disabling network encryption, enabling SSID broadcasting, not implementing MAC address filtering, and never updating firmware.

• Using simple passwords, disabling network encryption, enabling SSID broadcasting, not implementing MAC address filtering, and infrequently updating firmware.

• Using weak passwords, disabling network encryption, enabling SSID broadcasting, not implementing MAC address filtering, and rarely updating firmware.

• Using strong passwords, enabling network encryption, disabling SSID broadcasting, implementing MAC address filtering, and regularly updating firmware.

How can you troubleshoot network connectivity issues?

• Check the weather forecast

• Restart the computer

• Unplug the router

• To troubleshoot network connectivity issues, you can follow these steps: Check physical connections, restart devices, check IP configuration, perform a ping test, check firewall settings, update drivers, disable security software, and reset network settings.
