What is the difference between Microsoft Systems Engineer vs Network Administrator?

The Microsoft Systems Engineer primarily focuses on designing and managing Microsoft-based systems and infrastructure, often requiring certifications like Microsoft Certified: Windows Server. In contrast, a Network Administrator concentrates on maintaining and troubleshooting network hardware and connectivity, with certifications like Cisco CCNA. While both roles are essential in IT environments, the Systems Engineer has a broader scope involving system architecture, whereas the Network Administrator specializes in network operations.
