F5CAB1 Install, Initial Configuration, and Upgrade Practice Question
After upgrading a BIG-IP, the administrator notices that specific traffic management features are now missing. What is the most likely reason?
⚠ Common exam trap
Candidates mistakenly believe that software updates automatically retain all previous module allocations, failing to check module provisioning after completing a major version upgrade.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The modules were not provisioned after the reboot.
Missing features after an upgrade often result from improper provisioning. When upgrading to a newer BIG-IP version, the resource allocation for modules (e.g., LTM, AFM) may be reset or require manual reassignment. If the module is not correctly provisioned to a 'Nominal' or 'Dedicated' level, the associated functionality will not be loaded into the memory, making the features appear absent even though the software version is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The license was invalidated by the upgrade.
Why it's wrong here
Upgrading the software does not inherently invalidate a license. Unless the service contract is expired, the license remains valid. If features are missing, it is almost certainly a configuration issue regarding resource provisioning, not a licensing issue resulting from the upgrade itself.
- ✓
The modules were not provisioned after the reboot.
Why this is correct
After a major upgrade, module provisioning levels can sometimes be reset or require re-confirmation. If a module is not provisioned, the related traffic management services cannot start. The administrator must check the 'Provisioning' menu in the Configuration Utility to ensure the necessary modules are allocated appropriate resources.
- ✗
The configuration file was deleted.
Why it's wrong here
Configuration files are not automatically deleted during an upgrade; they are migrated to the new version. If features are missing, it is a matter of the system not running the necessary service to execute those features, not because the configuration file itself was removed from the system.
- ✗
The browser cache requires clearing.
Why it's wrong here
While browser cache issues can occur, they usually manifest as visual glitches in the GUI. If traffic management features are truly missing, it is a backend service issue (provisioning), not a frontend display issue. Clearing the cache will not restart the required processes on the TMOS kernel.
