F5 Configuring BIG IP DNS - BIG-DNS
WGAC-F5N-BIG-DNS
Schedule
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.
Audience
This course is intended for system and network administrators responsible for installation, setup, configuration, and
administration of BIG-IP DNS systems.
There are no F5-technology-specific prerequisites for this course: However, completing the following before attending would be helpful for students with limited BIG-IP administration and configuration experience:
Administering BIG-IP instructor-led course or F5 Certified BIG-IP Administrator
The following free web-based courses, although optional, will be very helpful for any student with limited BIG-IP administration and configuration experience.
Getting Started with BIG-IP web-based training
Getting Started with BIG-IP DNS web-based training
The following general network technology knowledge and experience are recommended before attending any F5 Global Training Services
instructor-led course:
OSI model encapsulation
Routing and switching
Ethernet and ARP
TCP/IP concepts
IP addressing and subnetting
NAT and private IP addressing
Default gateway
Network firewalls
LAN vs. WAN
The following course-specific knowledge and experience is suggested before attending this course:
DNS resolution process
Experience configuring DNS content and resolution servers
DNSSEC
Students should be able to:
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
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
