An F5 administrator is configuring a new virtual server for a critical application and needs to ensure that if the primary persistence method fails, a backup method is used. The primary requirement is Source Address persistence, with a fallback to SSL session ID persistence if no source address match is found. How should this be configured on the virtual server?
A BIG-IP device in a high-availability (HA) pair is rebooted into the End User Diagnostics (EUD) utility to check for potential hardware faults. After the tests complete, the administrator needs to save the results for analysis and for a potential F5 support case. What is the correct procedure to obtain the EUD output?
A web application is experiencing intermittent slowness. The administrator suspects the issue is related to how the BIG-IP is handling HTTP content, possibly with compression or caching. Standard dashboard statistics do not provide enough detail. To investigate further, the administrator decides to use `tcpdump`. Which `tcpdump` flag is essential for viewing the unencrypted HTTP payload on a virtual server that has a Client SSL profile applied?
An administrator cannot access the BIG-IP Configuration Utility (GUI) via a self-IP address that is normally used for management. SSH access to the same self-IP is working correctly. The administrator suspects a Port Lockdown setting is the cause. Where in the Configuration Utility would the administrator verify and modify the Port Lockdown settings for the self-IP?
When preparing to open a support case with F5 for a complex application delivery issue, what is the single most important diagnostic file that should be generated and uploaded to iHealth before contacting support?
An administrator is viewing the Network Map in the BIG-IP Configuration Utility and notices that a pool member is displayed as a blue square. What does this status icon indicate?
An administrator needs to perform a software upgrade on a high-availability (HA) pair of BIG-IP devices with minimal downtime. Which of the following represents the correct, F5-recommended strategy for this operation?
During a maintenance window, an administrator needs to gracefully remove a pool member from service to perform updates on the backend server. The goal is to prevent any new connections from being sent to this member, while allowing existing, persisted connections to complete. Which action should the administrator take on the pool member?
A virtual server is configured with a pool that uses the 'Least Connections (member)' load balancing method. An administrator observes that one pool member, despite being healthy and having a high connection limit, is receiving significantly less traffic than the others. Which of the following is the most likely reason for this behavior?
An administrator is creating a new user account that should only be allowed to view statistics and object statuses, but not make any configuration changes. Which user role should be assigned to this account?
