F5CAB1 Exam Dumps - F5-CA Questions and Answers

The screenshot shown is from the User Administration section of the BIG-IP GUI.

This section controls:

Root and Admin passwords

SSH Access

SSH IP Allow settings

However, it does not contain any controls for restricting access to the WebUI (TMUI) .

BIG-IP does not provide TMUI access restrictions from this part of the GUI.

Access to the web-based Configuration Utility is controlled by the httpd allow list , configured through TMSH:

tmsh modify /sys httpd allow { < IP/subnet > }

This setting is not displayed in the User Administration panel, and in many BIG-IP versions, the httpd allow list is only configurable from the CLI , not the GUI.

Therefore, the administrator cannot find the setting in the screen shown because:

TMUI access restriction is not located in this GUI section

It must be configured using tmsh under /sys httpd allow

This is why Option A is correct.

BIG-IP allocates CPU and memory resources based on module provisioning levels.

To view how much CPU a module is assigned, administrators must check provisioning information from:

C. GUI — System » Resource Provisioning

This page visually displays CPU allocation via color-coded bars.

Hovering over the CPU bar shows:

CPU usage percent per module

Which modules share CPU cycles

The system’s total resource allocation

This is the primary GUI method.

D. tmsh show /sys provision

This command displays detailed module provisioning information including:

Provisioned modules

Their provisioning level

CPU and memory allocation data

It is the authoritative CLI method for resource provisioning status.

Why the other options are incorrect:

A. top

Shows real-time process usage, not provisioned CPU allocation.

B. tmsh show /sys cpu

Displays CPU runtime utilization, not per-module provisioning.

E. Statistics Dashboard

Only shows traffic / system runtime metrics, not provisioning resource allocations.

Therefore, C and D are correct.

The BIG-IP system has built-in licensing enforcement.

If an administrator provisions a module that the device is not licensed to run, the system will still allow the provisioning action to occur initially , but the system detects the mismatch and displays an alert.

What actually happens:

The GUI places a warning banner in the upper-left corner labeled something similar to: “Provisioning Warning”

This appears immediately after provisioning a module that is not included in the active license.

The system remains in an “inconsistent state” until the module is disabled again or the license is updated.

This is the visual cue BIG-IP uses to indicate that a module was provisioned without valid licensing.

Why the other options are incorrect:

A. “A BIG-IP does not allow unlicensed modules to be provisioned.”

Not true. BIG-IP does allow provisioning, but warns afterward.

B. “A warning will appear when provisioning an unlicensed module.”

The warning does not appear during the provisioning step itself.

It appears after provisioning , in the main GUI, as a system banner.

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.
