Network Part 2

What is the purpose of routing protocols in a network?

• To encrypt all data packets in a network

• To increase network latency

• To determine the best path for data packets in a network.

• To limit the number of devices connected to the network

Name two common routing protocols used in networking.

• OSPF and BGP

• RIP and EIGRP

• VLAN and STP

• IS-IS and MPLS

Explain the concept of network security and why it is important.

• Network security is unnecessary as most cyber threats are not serious.

• Network security is only relevant for large companies, not small businesses.

• Network security is primarily focused on increasing network speed, not protecting data.

• Network security is crucial for protecting data, maintaining network functionality, and preventing unauthorized access or cyberattacks.

What are some common security measures used to protect a network?

• Antivirus software, weak passwords, outdated software

• Firewalls, encryption, strong passwords, multi-factor authentication, regular software updates, intrusion detection systems, security audits

• Physical security measures, biometric authentication, social engineering

• Public Wi-Fi networks, sharing passwords, clicking on unknown links

What are the advantages of wireless networks?

• Limited range

• High security risks

• Incompatibility with certain devices

• Advantages of wireless networks include mobility, easy installation, cost-effectiveness, scalability, and flexibility.

What are some potential security risks associated with wireless networks?

• Unauthorized access, interception of data, rogue access points, denial of service attacks

• Physical security risks, Weather interference, Lack of encryption

How would you troubleshoot a network connectivity issue?

• Ask the network to fix itself

• Perform a rain dance

• Blow on the network cables

• Troubleshoot network connectivity by checking physical connections, restarting devices, verifying settings, addressing software/firewall issues, and testing with other devices.

Explain the concept of network virtualization.

• Network virtualization combines hardware and software resources into a single software-based entity to enable multiple virtual networks on a single physical infrastructure.

• Network virtualization is a process of combining physical and virtual networks into a single entity.

• Network virtualization only involves software resources without any hardware components.

• Network virtualization is a physical network infrastructure that is divided into multiple virtual networks.

What are the benefits of implementing network virtualization?

• Decreased performance, limited scalability

• Increased complexity, higher costs

• Multiple benefits such as resource utilization, flexibility, management ease, security, and cost savings.

• Reduced security, lack of control

What are some common tools used for network troubleshooting?

• SSH

• Ping, Traceroute, Netstat, Nslookup, Wireshark, Telnet

• FTP

• ARP
