NEW QUESTION # 34
A configuration change is made on the standby member of a device group. What is displayed as
"Recommended Action" on the Device Management Overview screen?
- A. Synchronize the active member configuration to the group.
- B. Force active member of device group to standby
- C. Synchronize the standby member configuration to the group
- D. Activate device with the most recent configuration
Answer: C
Explanation:
The BIG-IP Control Plane monitors the "Commit ID" of the configuration on all group members. When a change is made on the Standby unit, it becomes the member with the most recent configuration. The
"Recommended Action" in the HA status dashboard will be to synchronize that specific device's configuration to the rest of the group to ensure consistency
NEW QUESTION # 35
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)
- A. Local Traffic > Virtual Servers
- B. System > Configuration
- C. Local Traffic > Policies
- D. System > Archives
Answer: D
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.
NEW QUESTION # 36
What can the BIG-IP Administrator do when restoring BIG-IP configuration files with a UCS archive?
(Choose two answers)
- A. The BIG-IP Administrator can only restore the UCS archive to the same system from which it was saved.
- B. The BIG-IP Administrator can restore a UCS archive on a BIG-IP system on a different platform.
- C. The BIG-IP Administrator can only restore a UCS archive on a BIG-IP system running the same version.
- D. The BIG-IP Administrator can restore a UCS archive on a BIG-IP system running a later software version than the version of software the UCS archive was created on.
Answer: B,D
Explanation:
The User Configuration Set (UCS) is a flexible tool designed by the Control Plane to handle various lifecycle management scenarios, including upgrades and hardware migrations.
* Version Compatibility (Option B): TMOS is designed to be backward compatible. The Control Plane can ingest a UCS file created on an older version of software and automatically upgrade the configuration objects to match the current, later version during the restore process.
* Platform Portability (Option C): While a UCS archive contains platform-specific information, the BIG-IP system allows for "platform-independent" restores. This is a vital procedural concept for migrating from one hardware model to another or from physical hardware to a Virtual Edition (VE).
* Management of State: When restoring to a different platform or a later version, the administrator often uses specific flags (such as no-license or platform-migrate in later versions) to ensure that only the portable configuration data is applied while preserving the new platform's unique identifiers.
NEW QUESTION # 37
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?
- A. Local Traffic > Virtual Servers
- B. System > Configuration
- C. Local Traffic > Policies
- D. System > Archives
Answer: D
Explanation:
Managing the state of a device often involves restoring configuration backups known as User Configuration Set (UCS) files These archives contain the full system configuration, including licenses and SSL certificates.
The Control Plane provides a dedicated management area for these files under System > Archives, where administrators can upload, create, and restore configuration snapshots
NEW QUESTION # 38
Which TMSH command initiates a manual configuration synchronization to the specified device group? (Choose one answer)
- A. tmsh run sys device-group update-config
- B. tmsh load sys config to-group <device_group>
- C. tmsh run cm config-sync to-group <device_group>
- D. tmsh modify sys failover auto-sync enable
Answer: C
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
In a BIG-IP Device Service Cluster (DSC), manual configuration synchronization is performed using the ConfigSync framework. The supported and documented command to manually push the local configuration to a specific device group is:
tmsh run cm config-sync to-group <device_group>
This command:
Initiates a one-time manual ConfigSync
Pushes the local device's configuration to all members of the specified device group Is commonly used when auto-sync is disabled or when the administrator wants explicit control over synchronization timing Why the other options are incorrect:
A is not a valid TMSH command for ConfigSync.
B enables auto-sync but does not perform an immediate synchronization.
D is not a valid or supported TMSH command for device group configuration synchronization.
Therefore, the correct command to manually synchronize configuration to a device group is C.
NEW QUESTION # 39
The BIG-IP Administrator generates a qkview using "qkview -s0" and needs to transfer the output file via SCP. Which directory contains the output file?
- A. /var/config
- B. /var/local
- C. /var/tmp
- D. /var/log
Answer: C
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: A QKView is a comprehensive snapshot of the device's Control Plane state, configuration, and logs used for troubleshooting. By default, the qkview utility stores its generated output file in the /var/tmp/ directory. Administrators must know this path to retrieve the file for upload to F5 iHealth or Support.
NEW QUESTION # 40
A BIG-IP Administrator needs to load a UCS file but must exclude the license file.
How should the administrator perform this task? (Choose one answer)
- A. From the CLI with command tmsh load /sys ucs <ucs filename> no-license
- B. From the GUI, select the UCS file and click Restore
- C. From the GUI, select the UCS file, uncheck the license box, and click Restore
- D. From the CLI with command tmsh load /sys ucs <ucs filename>
Answer: A
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
When restoring a User Configuration Set (UCS) file, BIG-IP allows administrators to selectively exclude the license during the restore process. From the CLI, this is accomplished using the no-license option with the tmsh load /sys ucs command.
The command:
tmsh load /sys ucs <ucs filename> no-license
restores:
System configuration
Certificates and keys
Device and traffic objects
while explicitly excluding the license file, which is required when:
Migrating configurations between devices
Restoring to hardware with a different license
Avoiding license conflicts or overwrites
Why the other options are incorrect:
A does not provide the option to exclude the license.
B restores the UCS including the license, which does not meet the requirement.
D is incorrect because the BIG-IP GUI does not provide a checkbox to exclude the license during UCS restore.
Therefore, the correct and supported method is C.

NEW QUESTION # 42
A BIG-IP Administrator defines a device Self IP. The Self IP is NOT reachable from the network. What should the administrator verify first?
- A. The correct Interface has been selected.
- B. The correct VLAN has been selected.
- C. The correct Trunk has been selected.
- D. Verify if auto last hop is disabled.
Answer: B
Explanation:
Connectivity management requires a proper logical-to-physical mapping within the BIG-IP Control Plane.
* VLAN Association: In TMOS, a Self IP address is not assigned directly to a physical interface. Instead, it is assigned to a VLAN (Virtual Local Area Network) object.
* Procedural Troubleshooting: If a Self IP is unreachable, the primary failure point is often that the IP was associated with the wrong VLAN, or the VLAN itself is not correctly associated with the intended physical interface or trunk.
* Layer 2 Mapping: The Control Plane requires the VLAN to be "up" and "untagged" or "tagged" on a valid interface for traffic to flow. If the administrator selects the incorrect VLAN, the Self IP will exist in the configuration but will be logically isolated from the physical network wire.
NEW QUESTION # 43
One of the two members of a device group has been decommissioned. The BIG-IP Administrator tries to delete the device group, but is unsuccessful.
Prior to removing the device group, which action should be performed? (Choose one answer)
- A. Make sure all members of the device group are in sync
- B. Disable the device group
- C. Remove the decommissioned device from the device group
- D. Remove all members from the device group
Answer: C
Explanation:
A BIG-IP device group cannot be deleted if it still contains device members, even if one of those devices has already been decommissioned or is unreachable. Before deleting the device group, the administrator must explicitly remove the decommissioned device from the device group configuration.
Once the removed or unreachable device is deleted from the device group membership, the BIG-IP system allows the remaining administrator to successfully delete the device group.
Why the other options are incorrect:
* A. Remove all members from the device groupThis is not required; the key requirement is removing the decommissioned device, not all members.
* B. Make sure all members are in syncSynchronization status does not prevent device group deletion.
* D. Disable the device groupDevice groups cannot be disabled; they must be modified or deleted.
Therefore, the correct prerequisite action is to remove the decommissioned device from the device group, making C the correct answer.
NEW QUESTION # 44
A BIG-IP Administrator needs to determine who changed a Virtual Server configuration.
In which log file would the BIG-IP Administrator find this data? (Choose one answer)
- A. /var/log/ltm
- B. /var/log/audit
- C. /var/log/secure
Answer: B
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
The audit log (/var/log/audit) records configuration changes made on the BIG-IP system, including:
Who made the change (user account)
What was changed (for example, a virtual server modification)
When the change occurred
How it was performed (GUI, TMSH, or API)
Why the other options are incorrect:
/var/log/secure logs authentication events such as login successes and failures, not configuration changes.
/var/log/ltm logs traffic-management and runtime LTM events, not administrative configuration modifications.
Therefore, the correct log file for tracking who changed a virtual server is /var/log/audit.
NEW QUESTION # 45
A BIG-IP Administrator reviews the Plane CPU Usage performance chart and discovers a high percentage of Control Plane utilization. Which type of traffic does this indicate a higher usage of?
- A. Accelerated
- B. Administrative
- C. Application
- D. Tunnel
Answer: B
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: F5 architecture distinguishes between the Data Plane (TMM processing application traffic) and the Control Plane (Linux host processing management tasks). High Control Plane CPU utilization typically points to administrative activities such as heavy GUI usage, complex API calls (iControl), large-scale configuration synchronizations, or intensive logging/monitoring tasks rather than the actual switching or load balancing of application data.
NEW QUESTION # 46
A BIG-IP Administrator makes a configuration change to the BIG-IP device. Which file logs the message regarding the configuration change?
- A. /var/log/messages
- B. /var/log/user.log
- C. /var/log/audit
- D. /var/log/secure
Answer: C
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: Audit logging is a specialized feature within TMOS designed to track administrative actions. According to F5 documentation, whenever a system object (like a virtual server, pool, or profile) is created, modified, or deleted, the system records the event. These logs are stored specifically in /var/log/audit. This is essential for control plane administration to track "who did what and when" regarding the device configuration.
NEW QUESTION # 47
A BIG-IP Administrator suspects that one of the BIG-IP device power supplies is experiencing power outages. Which log file should the BIG-IP Administrator check to verify the suspicion?
- A. /var/log/daemon.log
- B. /var/log/ltm
- C. /var/log/audit
- D. /var/log/kern.log
Answer: B
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: Although /var/log/ltm is primarily associated with Local Traffic Manager events, it is also the primary destination for system-level alerts generated by the Control Plane's chmand (Chassis Manager Daemon). Hardware status changes, including power supply failures, fan speeds, and temperature warnings, are logged as "notice" or "critical" events within the LTM log file.
NEW QUESTION # 48
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?
- A. Statistics > Module Statistics > Traffic Summary1
- B. Statistics > Module Statistics > Local Traffic > Virtual Servers567
- C. Statistics > Module Statistics > Local Traffic > Virtual Addresses
- D. Statistics > Analytics > Process CPU Utilization234
Answer: B
Explanation:
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.
NEW QUESTION # 49
One of the two members of a device group has been decommissioned. The BIG-IP Administrator tries to delete the device group, but is unsuccessful. Prior to removing the device group, which action should be performed?
- A. Remove the decommissioned device from the device group
- B. Make sure all members of the device group are in sync
- C. Disable the device group
- D. Remove all members from the device group
Answer: D
Explanation:
To maintain integrity in a High Availability environment, TMOS prevents the deletion of active Devic28e Groups. Procedurally, a device group is a container for synchronization; the Control Plane requires that you first strip the group of all associated members (devices) before the group object itself can be removed from the configuration.
