- Given a customer environment, requirements, and constraints, select an appropriate deployment model - Given a customer environment, requirements, and constraints, recognize the use case for DNS Express, Zone Runner, DNS 64, DNSSEC, DNS Cache, various load balancing algorithms, persistence, and/or health monitor |
| Determine performance requirements for a BIG-IP DNS solution |
- Relate the performance characteristics of virtual edition and physical hardware to a specific use case - Employ topology load balancing to optimize user experience - Predict the performance implications pertaining to key DNS features (e.g., DNSSEC, topology LB) |
IMPLEMENT |
|
| Identify configuration options for TMOS and sync groups |
- Create the proper self-IP configuration, routes, and settings for iQuery communications - Ensure proper NTP operation of all sync group members - Create logging profiles for DNS request and/or response |
| Identify configure options for GSLB |
- Differentiate between, and determine when to use, the two tiers of GSLB pool selection and the three tiers of virtual server selection - Recognize the functionality of various load balancing methods (e.g., static, dynamic, and fallback) - Recognize topology load balancing configuration parameters |
| Identify configuration options for non-GSLB DNS components |
- Determine the listener IP and protocol - Configure DNS Express and DNS Cache |
| Identify the necessary network environment for GSLB operations |
- Recognize the significance of source and destination ports for communication between BIG-IP DNS devices - Identify missing/non-functional network configurations when enabling GSLB operation (e.g., iQuery, generic host probing) |
TEST AND TROUBLESHOOT |
|
| Determine when and how to employ the appropriate network and DNS troubleshooting tools |
