Network maintenance is primarily focused on keeping the network up and running smoothly, ensuring that users can access resources and applications without disruptions.

Installing new network equipment is typically not considered a maintenance task, as it involves adding new components to the network rather than maintaining existing ones.

Network troubleshooting involves identifying the root cause of network issues and taking steps to resolve them, restoring network functionality and performance.

Ping, Traceroute, and SNMP are all commonly used network monitoring tools that provide valuable information about network connectivity, performance, and device status.

The frequency of network maintenance tasks can vary depending on the size and complexity of the network, as well as the specific maintenance requirements of the network components. It is generally recommended to perform maintenance tasks as needed, based on monitoring results and identified issues.

Using outdated software and firmware is not a recommended network maintenance practice, as it can introduce security vulnerabilities and compatibility issues. Keeping software and firmware up to date is essential for maintaining network security and performance.

Network optimization involves fine-tuning network configurations, implementing traffic engineering techniques, and optimizing routing protocols to improve network performance, reduce latency, and increase bandwidth utilization.

Load balancing, traffic shaping, and QoS are all common network optimization techniques used to improve network performance and efficiency by distributing traffic load, prioritizing network traffic, and ensuring that critical applications receive the necessary bandwidth and resources.

Implementing multiple layers of security, such as firewalls, intrusion detection systems, and encryption, provides a more comprehensive and effective approach to protecting the network from various threats and vulnerabilities.

Malware, phishing attacks, and DDoS attacks are all common network security threats that can compromise network integrity, disrupt operations, and steal sensitive information.

Network security review involves periodically examining and evaluating network security policies, procedures, and configurations to identify vulnerabilities, ensure compliance with regulations, and make necessary updates to improve overall network security.

Ignoring security alerts and notifications can lead to missed opportunities to address potential security threats and vulnerabilities. It is essential to promptly investigate and respond to security alerts to maintain a secure network.

Using a centralized documentation system, such as a wiki or documentation repository, ensures that all network documentation is stored in a single, easily accessible location, making it easier to find and update information.

Financial statements are not typically considered a type of network documentation, as they are not related to the technical aspects of network maintenance and management.

Network capacity planning aims to forecast future network traffic demands and ensure that the network has the necessary resources, such as bandwidth, equipment, and infrastructure, to meet those demands and support the growing needs of users and applications.
