F5 Networks Configuring BIG IP DNS: Domain Name System

Audience:

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

Prerequisites:

Administering BIG-IP; TCP/IP Addressing and Routing, WAN/LAN elements; and Data Center Server redundancy concepts.

Description:

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.

Course Objectives:

After completing this course, students should be able to meet the following course objectives:

• Provision the BIG-IP system for operation
• Back up the BIG-IP system configuration for safekeeping
• Describe how the Domain Name System (DNS) resolves host names 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
