The following course-specific knowledge and experience is suggested before attending this course:

  • DNS resolution process
  • Experience configuring DNS content and resolution servers
  • DNSSEC

Delegates will learn how to

  • BIG-IP initial setup (licensing, provisioning, and network configuration)
  • Overview of the Domain Name System and DNS resolution flow through BIG-IP DNS
  • Configuring DNS listeners
  • Accelerating DNS resolution with DNS Express, DNS cache, and DNS server load balancing
  • Intelligent DNS resolution with wide IPs and wide IP pools
  • Using probes and metrics to assist the intelligent DNS resolution process
  • Intelligent DNS load balancing methods
  • Monitoring intelligent DNS resources
  • Logging GSLB load-balancing decisions
  • Using DNSSEC
  • Integrating iRules in the DNS resolution process
  • Managing BIG-IP DNS sync groups
