LENGTH: 16 Hours (2 dage)

PRICE: kr 14.900,00


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


Major Course Changes since v14.1

The Configuring DNS v14.1 course presents much of the same content as v13, with very minor additions including an explanation of the new EDNS0 feature.


•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


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