4 F5-LOAD BALANCER-2 COURSE TOPICS Section1: Troubleshoot BLUEPRINT basic virtual Server connectivity issues Given a connectivity troubleshooting situation, consider the packet and virtual server processing order Identify the reason a virtual server is not working as expected Identify the reason a pool member has been marked down by health monitors Identify a pool member not in the active priority group Identify traffic diverted due to persistence record Identify the current configured state of the pool member Identify a persistence issue Section 2: Troubleshoot basic hardware issues Perform an End User Diagnostic per F5 documentation and collect the output Interpret the LCD Warning Messages Identify a possible hardware issue within the log files Force an active unit to standby under the appropriate circumstances Understand the relationship between interfaces, trunks, VLANs and their status/statistics Section 3: Troubleshoot basic performance issues Recognize when a packet capture is needed within the context of a performance issue Use BIG-IP tools in order to identify potential performance issues Section 4: Troubleshoot basic device management connectivity issues Verify remote connectivity to the BIG-IP in order to determine the cause of a

5 management connectivity issue Check and interpret port lockdown settings and packet filters in order to determine the cause of a management connectivity issue to a Self-IP Given the use of a remote authentication server, verify proper DNS and NTP settings in order to diagnose a connectivity issue Section 5: Open a support ticket with F5 Identify the appropriate supporting components and severity levels for an F5 support ticket Given an issue, determine the appropriate severity according to F5 guidelines Provide quantitative and relevant information appropriate for a given issue Section 6: Identify and report current device status Review the Network Map in order to determine the status of objects Use the dashboard to gauge the current running status of the system Review log files and identify possible events Use iapps Analytics to gauge the current running status of application services Section 7: Maintain system configuration Create and restore a UCS archive under the appropriate circumstances Identify which high-level tasks can be automated using BIG-IQ Manage software images Given an HA pair, describe the appropriate strategy for deploying a new software image Understand the processes of licensing, license reactivation, and license modification (add-ons) Identify which modules are licensed and/or provisioned Explain how to create a user Explain how to modify user properties

6 Section 8: Manage existing system and application services Modify and manage virtual servers Modify and manage pools
