F5 BIG-IP Administration Install, Initial Configuration, and Upgrade Sample Questions (Q46-Q51):NEW QUESTION # 46
A BIG-IP Administrator is responsible for deploying a new software image on an F5 BIG-IP HA pair and has scheduled a one-hour maintenance window.
With a focus on minimizing service disruption, which of the following strategies is the most appropriate?
  • A. Update the standby node first and reboot it to the newly updated boot location, failover to the newly updated node and verify functionality. Repeat the upgrade procedures on the next node, which is now in standby mode.
  • B. Reset the Device Trust, apply the update to each node separately, reboot both nodes, then re-establish the Device Trust.
  • C. Update the active node first, reboot to the newly updated boot location and verify functionality, then push the update from the active to the standby node and reboot the standby node.
  • D. Update both nodes in the HA pair, then reboot both nodes simultaneously to ensure they run the same software version.
Answer: A
Explanation:
For BIG-IP high-availability (HA) pairs, F5's recommended upgrade workflow prioritizesservice continuity, predictable failover, andminimal downtime. The established best-practice sequence is:
* Upgrade the standby unit first
* Because the standby device is not passing traffic, upgrading and rebooting it does not impact production.
* Boot the standby unit into the newly installed version
* Once online, the administrator verifies basic health, device sync status, cluster communication, and module functionality.
* Perform a controlled failover to the upgraded unit
* Traffic shifts to the newly upgraded device, allowing validation of the configuration and operational behavior under real traffic loads.
* Upgrade the second device (now standby)
* The previously active device becomes standby after failover, allowing it to be safely upgraded and rebooted without interruption.
This phased approach ensures only one device is unavailable at a time, allowing continuous traffic flow throughout the upgrade process.
Why the Correct Answer is C
OptionCexactly matches F5's documented production-safe upgrade method:
* Upgrade thestandbynode first
* Reboot into new image
* Failover to upgraded device
* Validate
* Upgrade the remaining (now-standby) device
This procedure minimizes risk and traffic disruption.
Why the other options are incorrect:
A). Upgrade the active node first
* Upgrading the active device requires removing it from service and failing over abruptly. This is not recommended and increases service disruption risk.
B). Resetting device trust
* Resetting trust is unnecessary and can disrupt configuration sync, peer communication, and cluster operation. It is not part of any standard upgrade workflow.
D). Upgrading and rebooting both nodes simultaneously
* This would causetotal outage, because both HA members would be unavailable at the same time.

NEW QUESTION # 47
A BIG-IP Administrator upgrades the BIG-IP LTM to a newer software version. After the administrator reboots into the new volume, the configuration fails to load.
Why is the configuration failing to load?
  • A. The license needed to be reactivated before the upgrade.
  • B. Connectivity to the DNS server failed to be established.
  • C. The upgrade was performed on the standby unit.
  • D. A minimum of at least two reboots is required.
Answer: A
Explanation:
When upgrading to a newer TMOS software version, BIG-IP validates whether the current license is permitted to run that version.
This is controlled by theService Check Datein the device's license file.
If the Service Check Date is older than the minimum required for the target version:
* The systemboots into the new volume,
* Butfails to load the configuration,
* And will instead present messages indicating that the configuration cannot be applied due to aninvalid or outdated license.
This is a well-known behavior:
An outdated license, not reactivated before upgrade, causes configuration load failure after reboot into the new software.
Why the other options are incorrect:
A). Performed on the standby unit
* Upgrading a standby unit does not cause configuration load failure.
* Standby-only upgrades are standard best practice.
C). Two reboots required
* BIG-IP does not require two reboots during an upgrade.
* One reboot into the new volume is sufficient.
D). DNS connectivity failure
* DNS connectivity does not affect configuration loading.
* DNS is only needed for automatic license activation, not for applying config at boot.
Thus, the configuration failed to load because thelicense was not reactivated before the upgrade, making Option Bcorrect.

NEW QUESTION # 48
An organization is planning to upgrade a BIG-IP system from16.1.xto17.1.x.
For a successful upgrade, theService Check Datemust be equal to or newer than the License Check Date required for 17.1.x.
Which command will show the Service Check Date on the BIG-IP system being upgraded?
  • A. grep "Service check date" /config/bigip.conf
  • B. grep "Service check date" /config/BigDB.dat
  • C. grep "Service check date" /config/svc_chk_date.dat
  • D. grep "Service check date" /config/bigip.license
Answer: D
Explanation:
BIG-IP licensing information, including theService Check Date, is stored in the file:
/config/bigip.license
This file contains all license attributes downloaded from the F5 licensing server, including:
* License key
* Licensed modules
* Useful life date
* Service check date
TheService Check Datedetermines whether the system is eligible for upgrades to specific TMOS versions.
When reviewing upgrade readiness, administrators extract this value directly from the license file with:
grep "Service check date" /config/bigip.license
Why the other options are incorrect:
* /config/bigip.confstores BIG-IP configuration objects, not license metadata.
* /config/svc_chk_date.datisnota valid file in the licensing system; it does not contain license parameters.
* /config/BigDB.datstores internal database values, not licensing attributes.
Thus, only thebigip.licensefile contains the correct licensing information required for verifying upgrade eligibility.

NEW QUESTION # 49
When is theLicense Service Check Dateenforced on a BIG-IP system?
  • A. After editing a virtual server
  • B. During a software install
  • C. During system startup
Answer: B
Explanation:
TheService Check Datedetermines whether a particular software version is allowed to run under the device's license.
* When installing or upgrading TMOS, the installer checks theService Check Datestored in the BIG-IP license file.
* If the license date isolderthan the minimum required for the target version, the software installation is blocked.
* This check happensspecifically during a software install, not during routine device operations.
Editing virtual servers or system startup do not trigger this validation.
Thus, the enforcement happensduring software installation.

NEW QUESTION # 50
Which command will display thecurrent active volumeon a BIG-IP system?
  • A. tmsh list sys software update
  • B. tmsh show sys software status
  • C. tmsh show sys version
Answer: B
Explanation:
To identify which boot volume is currently active on a BIG-IP system, the correct command is:
tmsh show sys software status
This command displays:
* All installed boot volumes (HD1.1, HD1.2, HD1.3, etc.)
* The BIG-IP software version installed on each volume
* TheActivefield, indicating which volume the system is currently booted from
* The installation status ("complete", "in-progress", "allowed")
This is thestandard and authoritativeway to determine the active boot location.
Why the other options are incorrect:
A). tmsh show sys version
* Displays OS version, build, and date.
* Doesnotshow boot locations or which volume is active.
C). tmsh list sys software update
* Shows software update configurations, not boot volume status.
* Does not display which volume is active.
