Question 1 of 46

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?

Answer choices
Show answer

Correct answer: B

An active license is required for BIG-IP to validate and load the configuration after booting into an upgraded software volume. Reactivating the license before the upgrade ensures that the license contains the current service-check date and is valid for the target software version. Without that update, the new version can boot but may reject the saved configuration. Upgrading the standby unit, performing additional reboots, or DNS reachability does not address license validation.

Question 2 of 46

Which command will display the current active volume on a BIG-IP system?

Answer choices
Show answer

Correct answer: B

The tmsh show sys software status command displays the BIG-IP software volumes and their states, including which volume is currently active. This lets an administrator verify the booted installation and identify inactive or available volumes for upgrades. The version command reports software version details but does not provide the active-volume status.

Question 3 of 46

The Port Lockdown feature prevents unwanted connection attempts to a self-ip.

Which types of three connection attempts are unaffected by the port lockdown settings?

Answer choices
Show answer

Correct answer: C

Defined virtual server traffic, ICMP, and CMI communication remain allowed regardless of a self IP’s Port Lockdown setting. Virtual server traffic must reach the BIG-IP system for configured application delivery services to function, while ICMP supports basic network diagnostics. CMI traffic is required for device trust and high-availability synchronization between BIG-IP devices. SSH is not automatically exempt and must be explicitly permitted when administrative remote access is needed.

Question 4 of 46

Which two items demonstrate the creation of a new volume for software images? (Choose two.)

Answer choices
Show answer

Correct answers: C, E

Creating a new software volume is performed as part of installing a BIG-IP software image. In tmsh, the install command uses the sys software image syntax and includes create-volume to create the specified target volume. In the GUI, Software Management provides the Available Images installation workflow, where a new volume name or number can be entered. Disk Management is not the interface used to create boot volumes for software image installation.

Question 5 of 46

An F5 BIG-IP administrator is asked to report which modules are provisioned on the BIG-IP. In which two ways can this be done? (Choose two.)

Answer choices
Show answer

Correct answers: A, B

The provisioning configuration lists each BIG-IP module and its allocated resource level, such as None, Nominal, Dedicated, or another provisioned setting. The tmsh command “list /sys provision” displays this configured provisioning information from the command line. In the GUI, System > Resource Provisioning > Module Allocation presents the same module allocation settings. The “show” command and module statistics pages focus on status or statistics rather than the configured provisioning allocation.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
