This module also includes troubleshooting techniques to ensure smooth name resolution across your network. By the end of this module, you’ll be able to configure and manage DNS to ensure reliable domain name resolution and improve network efficiency.

9. NTP and Syslog
In this module, you’ll learn about NTP (Network Time Protocol) and Syslog, two essential services for network monitoring and management. NTP ensures all devices on a network are synchronized with the correct time, which is critical for accurate logging and security. Syslog is used to collect, store, and analyze log messages from different network devices. This module covers the configuration of both services and explains how they help maintain a stable and secure network environment.
