NEW QUESTION # 63
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)
Answer: B
Explanation:
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.
NEW QUESTION # 64
Administrative user accounts have been defined on the remote LDAP server and are unable to log in to the BIG-IP device. Which log file should the BIG-IP Administrator check to find the related messages?
Answer: D
Explanation:
Authentication and authorization events are handled by the system's PAM (Pluggable Authentication Modules). For Control Plane security auditing, all login attempts--whether local or remote (LDAP/RADIUS/TACACS+)--and SSH-related security events are recorded in
/var/log/secure. This is the primary log for troubleshooting administrative access issues
NEW QUESTION # 65
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?
Answer: A
Explanation:
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.
NEW QUESTION # 66
Which file should the BIG-IP Administrator check to determine when a Virtual Server changed its status?
Answer: C
Explanation:
Monitoring and reporting current device status involves tracking the health of traffic objects like Virtual Servers20. The Control Plane logs transition events-such as a Virtual Server moving from 'Available' (green) to 'Offline' (red) due to health monitor failures-in the /var/log/ltm file21212121. While the audit log tracks who changed a configuration, the LTM log tracks system-initiated status changes22222222.
NEW QUESTION # 67
A BIG-IP Administrator needs to restore a UCS file to an F5 device using the Configuration Utility.
Which section of the Configuration Utility should the BIG-IP Administrator access to perform this task? (Choose one answer)
Answer: B
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
In the BIG-IP Configuration Utility, all system backup and restore operations-including UCS (User Configuration Set) file restoration-are performed from the Archives section.
The correct navigation path is:
System > Archives
From this location, the administrator can:
Upload UCS files
Restore UCS backups
Manage system archive files used for backup and recovery
Why the other options are incorrect:
A . System > Configuration is used for general system settings, not backup restoration.
C . Local Traffic > Virtual Servers is used for application traffic objects.
D . Local Traffic > Policies manages traffic policies, not system backups.
Therefore, the correct section to restore a UCS file using the Configuration Utility is System > Archives.
