Course Details

FutureLing IT also has a complete Domain Name System (DNS) Online Training which is aimed at IT professionals, network administrators and students who would like to master the backbone of the internet infrastructure. DNS is an essential technology that converts human-readable domain names to IP addresses to facilitate smooth communication between devices and servers across the globe.

This course includes the basic and advanced principles of DNS, such as domain name hierarchy, DNS zones, domain name records (A, CNAME, MX, TXT), authoritative server, recursive server, caching, and security (e.g. DNSSEC). The learners will also be able to acquire practical knowledge in configuring, troubleshooting, and optimization of DNS in enterprise networks and cloud deployment.

The training can be done online, whereby we have flexible learning involving live instructor-learner sessions, interactive demonstrations, and laboratory work. The tasks that the participants will undertake will be based on real-world examples like installing DNS servers, domain administration and efficient DNS solutions. This strategy provides in-depth knowledge of DNS concepts and the building of the practical skills needed in IT operations and network management.

Upon successful completion, students can be ready to receive DNS certification, which is a worldwide recognised title that confirms your capability in the field of network infrastructure and domain management, which would provide you with a competitive advantage in the IT and cybersecurity profession.

FutureLing IT also offers special interview preparation, such as mock interviews, scenario-based questions, and advice on problem-solving exercises.
