81. What is a network performance monitoring tool?
A network performance monitoring tool continuously collects and analyzes network data to evaluate and optimize network performance, detect bottlenecks, and troubleshoot issues.
82. What is the purpose of a network encryption protocol?
A network encryption protocol encrypts network traffic to ensure confidentiality and protect data from unauthorized access or interception. Examples include SSL/TLS, IPsec, and SSH.
83. What is network segmentation?
Network segmentation refers to dividing a network into smaller subnetworks or segments to improve security, performance, and manageability by isolating different types of traffic or user groups.
84. What is a network proxy server?
A network proxy server acts as an intermediary between clients and servers, forwarding client requests and responses while providing additional services such as caching, content filtering, or anonymization.
85. What is the purpose of a network intrusion prevention system (IPS)?
A network intrusion prevention system (IPS) monitors network traffic, detects and blocks malicious activities or intrusions in real-time, providing an active defense against network-based attacks.
86. What is a network routing protocol?
A network routing protocol determines the optimal path for data to travel in a network, exchanging routing information between routers and updating routing tables accordingly. Examples include OSPF, RIP, and EIGRP.

87. What is the purpose of a network traffic analyzer?
A network traffic analyzer captures and analyzes network traffic at the packet level, providing insights into protocols, performance, security, and troubleshooting.
88. What is a network packet filter?
A network packet filter examines packets at the network or transport layer based on predefined rules, allowing or blocking traffic based on various criteria such as source/destination IP, port, or protocol.
89. What is the purpose of a network bandwidth management technique?
A network bandwidth management technique regulates and controls the allocation of available bandwidth, ensuring fair and efficient distribution among network users or applications.
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.
