Which log file should the BIG-IP Administrator check to determine if a specific user tried to log in to the BIG-IP Configuration Utility? (Choose one answer)
On BIG-IP systems, all authentication attempts for administrative access---including logins to the Configuration Utility (GUI)---are logged in /var/log/secure. This log file records:
Successful and failed login attempts
The username used
The authentication method (local, LDAP, RADIUS, etc.)
Access denials and PAM authentication errors
Why the other options are incorrect:
/var/log/pam/tallylog tracks account lockouts and failed attempt counters, not detailed login attempts.
/var/log/ltm logs traffic management events, not administrative authentication.
/var/log/httpd logs web server activity but does not record authentication success or failure for BIG-IP administrative users.
Therefore, the correct log file to verify whether a user attempted to log in to the BIG-IP Configuration Utility is /var/log/secure.
An organization is performing a major release upgrade to its BIG-IP system. The system is under medium load and has enough disk space to perform the upgrade.
Which pre-upgrade task is disruptive to regular system performance and should be performed during a maintenance window? (Choose one answer)
Reactivating a BIG-IP license is a traffic-disruptive operation. During the license reactivation process, the BIG-IP system performs a configuration reload, which results in a temporary interruption of all traffic processing. Because traffic handling is affected, F5 explicitly recommends scheduling license updates during a maintenance window.
This behavior is documented in F5 Knowledge Base articles, which state that license reactivation impacts traffic and must be planned accordingly during upgrades or system changes.
The other options are not considered disruptive:
Creating a QKView is primarily a diagnostic task and does not interrupt traffic.
Running tmsh save sys config only saves the running configuration to disk.
Generating a UCS is resource-intensive but does not reload configuration or interrupt traffic processing.
A BIG-IP Administrator is setting up a new BIG-IP device. The network administrator reports that the interface has an incompatible media speed. The BIG-IP Administrator needs to change this setting manually. From which location should the BIG-IP Administrator perform this task?14
Comprehensive and Detailed Explanation From BIG-IP Administration20 Control Plane Administration documents: Connectivity management involves ensuring that the physical layer matches the networking environment. Interface properties, including media speed, duplex settings, and MTU, are managed at the Control Plane level under the Network menu. To resolve a mismatch with an upstream switch, the administrator must navigate to Network > Interfaces to manually override auto-negotiation settings.
A BIG-IP Administrator needs to update the list of configured NTP servers. In which area of the Configuration Utility should the BIG-IP Administrator perform this update?
NTP (Network Time Protocol) is vital for management connectivity and HA state synchronization. Correct time is required for log timestamping and device trust group communication46. To manage these settings, the administrator navigates to System > Configuration, where general system-level services like NTP and DNS are defined to ensure the Control Plane remains synchronized with the network environment.
A BIG-IP Administrator needs to view the CPU utilization of a particular Virtual Server. Which section of the Configuration Utility should the administrator use for this purpose?
Comprehensive and Detailed Exp11lanation From BIG-IP Administration Control Plane Administration documents: Monitoring specific object health is a core function of the Control Plane. While the dashbo12ard provides a global overview, granular per13formance data---such as the CPU overhead a specific Virtual Server is placing on the Traffic Management Microkernel (TMM)---is found under the Module Statistics. Navigating to Statistics > Module Statistics > Local Traffic > Virtual Servers allows an administrator to report on the current status and resource consumption of individual traffic objects.
