With over a decade of senior-level experience in IT, specializing in network administration and server management, I am confident that I am the right fit for your Secondary Active Directory Server Installation project. Equipped with a Microsoft MCSA 2012 certification, I have an expert understanding of Windows Servers, including your specific Windows Server 2019 setup. My proficiency in setting up backup servers for AD would be highly beneficial for this undertaking, as well.
Apart from AD installations and configurations, my skills extend to networking fundamentals such as routing (RIP, OSPF, EIGRP), VPN configuration (IPSEC/L2TP, GRE/PPTP), and storage area networks (SAN) deployment -- all skills that can synergistically contribute to the smooth implementation of a secondary AD server with real-time synchronization capabilities. My previous engagements involved creating and managing enterprise-scale networks similar to your requirements.
Lastly, I pride myself on my ability to empathetically understand the needs of clients and translate them into efficient solutions. I am eager to bring my seniority, expertise and all-rounded approach to effectively install and configure a secondary AD server to mirror the primary server's functionalities at your main branch. Together, let's ensure uninterrupted AD services even in worst-case scenarios.
