90. What is a network access point (NAP)?

A network access point (NAP) is a physical location where multiple networks interconnect to exchange data traffic. It acts as a hub for network interconnections, often used in internet exchange points.

91. What is the purpose of a network disaster recovery plan?

A network disaster recovery plan outlines procedures and strategies for restoring network operations and connectivity in the event of a network failure, natural disaster, or other disruptive events.

92. What is a network load balancer?

A network load balancer distributes incoming network traffic across multiple servers or resources to ensure efficient utilization, high availability, and scalability.

93. What is the purpose of network segmentation?

Network segmentation involves dividing a network into smaller segments or subnets to enhance security, manage traffic, and control access based on user groups or application requirements.

94. What is a network security policy?

A network security policy defines the rules, procedures, and guidelines for securing a network, including access control, authentication, encryption, incident response, and other security measures.

95. What is the purpose of a network vulnerability assessment?

A network vulnerability assessment identifies security weaknesses and vulnerabilities in a network infrastructure by scanning and analyzing network devices, systems, and configurations.

96. What is a network topology?

A network topology refers to the physical or logical arrangement of devices, links, and connections in a network. Common topologies include star, bus, ring, and mesh.

97. What is the purpose of a network access control (NAC) system?

A network access control (NAC) system enforces security policies by authenticating and authorizing devices or users before granting access to a network, ensuring only authorized and compliant devices are allowed.

98. What is a network firewall?

A network firewall is a security device or software that filters and controls incoming and outgoing network traffic based on predefined rules or policies, protecting the network from unauthorized access and threats.

99. What is the purpose of a network protocol analyzer?

A network protocol analyzer, also known as a packet sniffer, captures and analyzes network traffic at the packet level, providing insights into protocols, performance, and security issues.

100. What is a network intrusion detection system (NIDS)?

A network intrusion detection system (NIDS) monitors network traffic for signs of potential intrusions or attacks, providing alerts or taking preventive actions to protect the network from security threats.
