This course gives networking professionals a functional understanding of the BIG-IP DNS system as it is commonly used. The course covers configuration and ongoing management of the BIG-IP DNS system, and includes a combination of lecture, discussion, and hands-on labs.

• 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

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