Understanding Computer Threats and Network Topologies - 8x/CsU

What is a network topology?

• A protocol used to secure network traffic

• The physical or logical arrangement of network devices

• A device used to connect different network segments

• The process of assigning IP addresses in a network

Which of the following is a characteristic of a virus?

• It can replicate itself without user intervention

• It spreads across networks without attaching to a program or file

• It does not require a host program to cause damage

• It typically damages hardware components directly

What is the primary difference between a virus and a worm?

• A worm can operate independently, whereas a virus requires a host file to spread

• A virus can spread over networks, whereas a worm cannot

• Worms are less harmful than viruses

• Viruses are designed to steal information, whereas worms are not

Which network topology features a central hub that connects all devices?

• MESH

• Bus

• Star

• Ring

In which topology do data packets travel around in one direction from one device to another?

• MESH

• Bus

• Star

• Ring

What is a common vulnerability in a Bus topology?

• If the central hub fails, the entire network goes down

• It requires more cable than a Star topology

• If one device fails, it can bring down the entire network

• A break in the main cable can disrupt the entire network

Which of the following best describes a MESH topology?

• Devices are connected to a single cable

• Each device is connected to every other device

• Devices are connected in a circular layout

• A central device connects all other devices

What type of network threat involves software pretending to be beneficial while actually causing damage to your system?

• Phishing

• Trojan Horse

• Adware

• Spyware

What is the main purpose of network threats like viruses and worms?

• To improve system performance

• To provide unauthorized access to the system

• To protect data from external threats

• To disrupt normal system operations

Which network topology is this?

• Star
• Mesh
• Ring
• Bus
