F5 Networks Configuring BIG-IP DNS v14: Domain Name System

Description

F5 Networks Configuring BIG-IP DNS v14: Domain Name SystemThis 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.

 

 

Course Objectives | Configuring BIG-IP DNS

  • Provision the BIG-IP system for operation
  • Back up the BIG-IP system configuration for safekeeping
  • Describe how the Domain Name System (DNS) resolves hostnames into IP addresses
  • Describe how the BIG-IP DNS system can participate in the DNS resolution process
  • Use DNS Express on the BIG-IP DNS system to accelerate DNS resolution
  • Cache DNS query responses on BIG-IP DNS to accelerate DNS resolution
  • Load balance DNS queries to a pool of DNS servers and monitor pool health
  • Configure the key features of the BIG-IP DNS system to perform intelligent DNS resolution
  • Describe the LDNS probes used by BIG-IP DNS to support path-based load balancing
  • Configure a wide IP pool to use a path load balancing method
  • View and confirm DNS resolution behavior using path load balancing methods
  • Use static and dynamic load balancing methods to intelligently resolve DNS queries
  • Use persistence to effectively return one or more clients to the same virtual server on each query
  • Use manual resume to control certain load balancing behavior in the event of an outage
  • Configure and use load balancing decision logs to fine-tune and troubleshoot DNS resolution
  • Configure monitors on the BIG-IP DNS system in support of DNS resolution
  • Configure BIG-IP DNS to participate in the DNSSEC chain of trust
  • Configure limit settings on virtual servers, servers, and wide IP pools to temporarily direct client traffic away from resources that may not be performing at certain thresholds of efficiency
  • Configure iRules on a wide IP to customize intelligent DNS resolution
  • Describe the other wide IP types provided with BIG-IP DNS
  • Configure a BIG-IP DNS sync group
  • Apply all the principles learned throughout the course to configure a BIG-IP DNS system based on hypothetical specifications
