DNS Configuration in a Production Environment (Leading to RHCE)

About the Course:

Introduction To DNS(Domain Name Systems) Environments(From A Linux Perspective).

The course is designed to give participants an advanced introduction to DNS(Domain Name System), with configuration of servers (in a production environment) carried out from a Linux perspective. All appliances, servers, and systems have been simulated with virtualization, giving a what-you-see-is-what-you-get experience. The configurations are carried out in real-time, and are an exact depiction of what you would meet/experience in the IT industry, with regard to practices employed by Small-to-Medium Enterprises, and Large-to-Medium Enterprises alike. Participants can also expect comprehensive laboratory practice exercises, and can also opt for PRIVATE lab coaching sessions, which will be conducted in the same virtual production environments, if need be. This is one of the most comprehensive DNS courses participants will undergo, and it is expected that they possess(or, at least, have access to) an advanced IT-related knowledge base(and expertise, if need be). 

Participants can be sure that the level of understanding and comprehension that will be conveyed after the class has been completed will be satisfactory. It is hoped participants will have significant access time to a Personal Computer, as this will significantly enable them to perform ANY additional research that may be required, in order for them to get the best out of the course. With this level of understanding/comprehension, participants will therefore confidently be able to become unrivalled assets to the respective organisations they are able to achieve gainful employment in/with. The course can also be of significant benefit to participants who want to write their RHCSA/RHCE exams.

Course Objectives:

• This course aims to do that by performing DNS configuration on a Linux server with the aim of examining the different types of DNS configuration methods employed in today’s IT industry’s Production Environments, and making a similar deployment in a virtual production environment (a mail server will also be configured and deployed for testing purposes, and as a case study).

Who is the Target Audience?

• Participants who want to write their RHCSA/RHCE exams.
• Candidates preparing for RHCSA/RHCE certification
