Which command will provide the BIG-IP Administrator with the current device HA status? (Choose one answer)
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
To determine the current failover (HA) status of a BIG-IP system using tmsh, F5 documentation explicitly states that the administrator should use the following command:
show /cm failover-status
This command displays:
The current failover state (active, standby, or offline)
Detailed failover status information
The operational HA condition of the device within a device group
According to F5 Knowledge Base Article K08452454, the documented procedure for checking failover status is:
Log in to the TMOS Shell (tmsh)
Run show /cm failover-status
Why the other options are incorrect:
A . list /cm failover shows configuration settings, not operational HA status.
B . show /sys failover is not the documented command for checking current failover status and does not align with F5's recommended procedure.
A BIG-IP administrator is troubleshooting inconsistent configuration objects on devices in a device group. The administrator uses the command:
tmsh run /cm watch-devicegroup-device
and observes the following output:
devices
20:21 sync_test bigip_a 3273 bigip_a 14:27:00
20:21 sync_test bigip_b 1745 bigip_b 13:52:34 13:42:04
20:21 sync_test bigip_c 1745 bigip_a 13:52:34 13:42:04
What two conclusions can be made about this output? (Choose two answers)
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
watch-devicegroup-device shows (among other columns) the commit ID (cid.id / shown here as clu_id), the originating device for that commit (cid-orig / shown here as cl_orig), and the time the configuration change was made (cid.time / shown here as cl_time). The highest/newest commit ID and its time represent the most recent configuration change seen among the devices. (clouddocs.f5.com)
bigip_a has the latest configuration (A) because it shows commit ID 3273 at 14:27:00, which is newer than commit ID 1745 at 13:52:34 on bigip_b and bigip_c. (clouddocs.f5.com)
Two devices are out of date (B) because bigip_b and bigip_c are still on the older commit ID 1745, so they do not match the latest commit shown on bigip_a. (clouddocs.f5.com)
Why the other options are not supported by this output:
C is not supported: bigip_c is not showing a newer commit than the others; it's on the older commit (1745), so it's not the source of the most recent change. The output's cid-orig column is what tells you where the change was made. (clouddocs.f5.com)
D/E are incorrect logic: matching cid.time between two devices only indicates they share the same change timestamp/commit, not that it is the correct or latest configuration. The ''latest'' is indicated by the newest commit ID/time (here, bigip_a). (clouddocs.f5.com)
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?
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: 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
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?
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: 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 receives an RMA replacement for a failed F5 device. The Administrator tries to restore a UCS taken from the previous device, but the restore fails. The following error appears in the /var/log/ltm:
insufficient pool members. 01070608:3: License is not operational
(expired, digital signature does not match contents)
What should the BIG-IP Administrator do to avoid this error? (Choose one answer)
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
When restoring a UCS file to replacement hardware (RMA device), the license from the original device is not valid on the new system. If the UCS restore attempts to load the old license, BIG-IP reports license errors such as ''License is not operational'', which can prevent traffic objects (including pools and virtual servers) from loading correctly.
To avoid this issue, F5 documentation recommends restoring the UCS without the license, using the following command:
tmsh load /sys ucs <ucs filename> no-license
This approach:
Restores all configuration objects (LTM, networking, certificates, keys, etc.)
Excludes the invalid license tied to the old hardware
Allows the administrator to activate a new license separately on the replacement device
Why the other options are incorrect:
A . Remove the license information from the UCS archive
Not supported or recommended; UCS files should not be manually modified.
B . Revoke the license prior to restoring
License revocation does not prevent the UCS from attempting to load license data.
D . Reactivate the license on the new device using the manual activation method
This must be done after restoring the UCS and does not prevent the restore failure itself.
Therefore, the correct and supported method to avoid this error is C.
