Training

Configuring BIG-IP DNS (Formerly GTM) (TRG-BIG-DNS-IL)

Duration

2 days

Race Overview

This course offers network professionals a functional understanding of the BIG-IP DNS system as it is commonly used. The course covers the installation, configuration and management of the BIG-IP DNS system, and includes a combination of conferences, discussions and practical work.

Educational means:
  • Knowledge Verification Pre-Training Quiz (if applicable)
  • Training by a trainer
  • Realizable face-to-face or distancial training
  • Provision of remote labs/lab platform for each participant (if applicable to training)
  • Distribution of official English course materials for each participant
    • It is necessary to have a knowledge of technical English written for the understanding of course materials
Assessment:
  • Knowledge Verification Pre-Training Quiz (if applicable)
  • Formative evaluations during the training, through the practical work done on the labs at the end of each module, QCM, situation...
  • Completion by each participant of a questionnaire and/or upstream positioning questionnaire and at the end of the training for validation of skills acquisition

This course is intended for system and network administrators responsible for the installation, configuration and administration of BIG-IP DNS systems.

There are no F5-technology-specific requirements for this course:

However, completing the following before waiting would be very helpful for students with limited BIG-IP administration and configuration experience:

  • Administering BIG-IP (TRG-BIG-OP-ADMIN) instructor-led race
  • F5 Certified BIG-IP Administrator

The following web-based races, independently optional, will be very helpful for any student with limited BIG-IP administration and configuration experience:

  • Getting Started with BIG-IP web-based training
  • Getting Started with BIG-IP Global Traffic Manager (GTM) web-based training

The following general network technology knowledge and experience are recommended before waiting any F5 Global Training Services instructor-led course:

  • OSI model encapsulation
  • Routing and switching
  • Ethernet and ARP
  • TCP/IP concepts
  • IP addressing and subnetting
  • NAT and private IP addressing
  • Default gateway
  • Network firewalls
  • LAN vs. WAN

The following race-specific knowledge and experience is suggested before waiting this race:

  • DNS resolution process
  • Experience configuring DNS content and resolution servers
  • DNSSEC
  • Provision the BIG-IP system for operation
  • Back up the BIG-IP system configuration for safekeeping
  • Describe how the Domain Name System (DNS) solves host names into IP addresses
