Control Plane Administration questions frequently focus on device trust, failover behavior, and when config sync happens versus when changes are local. Expect scenario questions about adding a device to a cluster or interpreting sync status, study device groups, sync and failover mechanics, and common troubleshooting commands for management plane issues.

Most of my prep was tying data plane concepts to what you actually configure, especially profiles, SNAT behavior, and pool member health checks. That mindset helped on the scenario questions and I managed to pass on the first attempt.

On BIG IP Administration Data Plane Configuration the tricky questions were configuration troubleshooting tasks that ask which setting causes a failed translation or broken backend connectivity. Get hands-on with tmsh and the GUI, practice creating virtual servers, SNATs, and NATs, and memorize how config objects relate so you can spot misconfigurations quickly.

Big IP Administration Data Plane Concepts gave me the hardest questions where you trace a packet through profiles, iRules, and persistence to predict the final action. The exam items often present a packet flow diagram and ask which processing step applies first, so study the processing pipeline diagrams and practice tracing specific scenarios until it feels second nature, I passed and appreciated Pass4Success for a compact question set that sped up my prep.

I just cleared the BIG-IP Administration exam after studying intensively with Pass4Success practice questions, and the real test felt more manageable than I expected; one tricky item focused on VLAN tagging and network segmentation, specifically how to configure selfIP and the corresponding floating IP under a specific VLAN, which I nearly overthought but ultimately nailed through the practice drills—could you explain how a misconfigured selfIP would impact ARP responses in that scenario?

Free F5 Networks F5CAB1 Exam Actual Questions

Note: Premium Questions for F5CAB1 were last updated On Jul. 27, 2026 (see below)

Question #1

Given that BIGIP-.iso and Hotfix-BIGIP--ENG.iso have been uploaded to /shared/images on an F5 device, what is the appropriate tmsh command to prepare and update the BIG-IP device with the hotfix of a software version on a new volume HD1.2?

(Choose one.)

Reveal Solution Hide Solution
Correct Answer: B

When installing a BIG-IP software version with a HotFix on a new boot volume, F5 requires that both the base TMOS image and the HotFix image be installed together as part of the same installation workflow.

The correct process is:

Specify the base TMOS ISO

Specify the HotFix ISO that corresponds to that base version

Instruct the system to create a new boot volume

Install both images into that new volume

This is achieved with the following tmsh syntax:

tmsh install /sys software BIGIP-<version>.iso hotfix Hotfix-BIGIP-<version>-ENG.iso create-volume HD1.2

This command:

Installs the base image first

Applies the HotFix on top of the base image

Creates and installs everything on HD1.2

Leaves the currently active volume untouched for rollback

Why the other options are incorrect

A . Installing only the hotfix

A HotFix cannot be installed by itself on a new volume. A base image must already be present.

C . Using create instead of install

The create keyword is not valid for software installation operations.

D . Using copy

The copy command does not install software images or hotfixes.


Question #2

Which two items demonstrate the creation of a new volume for software images?

(Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, C

In BIG-IP, software images are installed on boot volumes (for example, HD1.1, HD1.2, HD1.3, etc.).

To install software on a new volume, the administrator must instruct the system to create a new boot location before installation.

There are two correct ways to create a new volume:

A . tmsh command (with correct syntax)

tmsh install software image /shared/images/BIGIP-<version>.iso volume HD1.5 create-volume

This syntax correctly includes:

install software image

full path to ISO (/shared/images/...)

volume name (HD1.5)

create-volume keyword

This instructs BIG-IP to create the new boot volume as part of the installation.

C . Using the GUI System > Disk Management

From the Disk Management menu, the administrator can:

Select ''New Volume''

Enter the volume identifier (e.g., HD1.5)

Apply changes

This GUI method is officially supported and explicitly creates a new boot volume before installing the software.

Why the other options are incorrect:

B . Incorrect tmsh syntax

Missing /shared/images/ path

Incorrect command structure

D . Incorrect command structure

Missing required keywords and correct command hierarchy

E . Software Management Install does NOT create volumes

This installs to an existing volume only

The GUI install dialog does not create new boot volumes

Thus, only Option A and Option C properly create a new software volume.


Question #3

A BIG-IP Administrator needs to install a HotFix on a standalone BIG-IP device.

The device currently has HD1.1 as the Active Boot Location.

The administrator has already reactivated the license and created a UCS archive.

In which sequence should the administrator perform the remaining steps?

Reveal Solution Hide Solution
Correct Answer: C

When installing a software upgrade with a HotFix on BIG-IP, the correct workflow requires:

Install the base TMOS image on an unused boot volume

Install the corresponding HotFix onto that same boot volume

Activate the updated boot volume to boot into the new software

This method ensures:

The existing active system (HD1.1) is untouched

The upgrade occurs in a new, clean volume (HD1.2)

The HotFix applies properly to the same base image

The administrator can revert to HD1.1 if issues occur

Option C matches the correct F5 upgrade sequence:

1. Install base image on HD1.2

2. Install HotFix on HD1.2

3. Activate HD1.2

Why the other options are incorrect:

A . Install HotFix before base image

HotFixes must be applied after the base image; not valid.

B . Installing a HotFix on the active boot location (HD1.1)

Not recommended and does not use a clean new volume.

Also does not involve installing the base image.

D . Activating HD1.2 before installing anything

Cannot activate an empty or invalid boot volume.

Thus, Option C is the correct sequence.


Question #4

Which of the following are resource allocation (provisioning) settings for BIG-IP modules?

(Choose two.)

Reveal Solution Hide Solution
Correct Answer: B, C

BIG-IP module provisioning determines how CPU, memory, and disk resources are allocated to each licensed module. F5 defines a specific set of supported provisioning levels.

Valid provisioning (resource allocation) settings

Nominal

Allocates a standard, balanced amount of system resources to a module.

Intended for typical production deployments where multiple modules may be provisioned at the same time.

Dedicated

Allocates all available system resources to a single module.

Used when the BIG-IP device is dedicated to running only one module (for example, ASM-only or APM-only deployments).

No other modules can be provisioned when one is set to Dedicated.

These two options are valid and supported provisioning levels.

Why the other options are incorrect

Maximum

This is not a valid BIG-IP provisioning level.

BIG-IP does not use ''Maximum'' as a resource allocation setting.

Limited

This is also not a supported provisioning level.

BIG-IP uses levels such as None, Minimal, Nominal, and Dedicated (module-dependent), not Limited.


Question #5

Which configuration file can a BIG-IP administrator use to verify the provisioned modules?

Reveal Solution Hide Solution
Correct Answer: C

Provisioning settings define which modules are enabled and how system resources are allocated to them.

These provisioning declarations are stored in:

/config/bigip.conf

This file contains:

Full module provisioning statements

TMSH-equivalent provisioning configurations such as:

sys provision ltm { level nominal }

sys provision asm { level nominal }

It is the primary system configuration file that stores all active provisioning details.

Why the other answers are incorrect

A . /config/bigip.license

Shows licensed modules, not provisioned modules.

B . /config/bigip_base.conf

Stores base networking (VLANs, Self-IPs, routes), not provisioning.

D . config.ucs

A backup archive, not a live configuration file.

Thus, the correct file to review active module provisioning is /config/bigip.conf.
