NEW QUESTION # 46
A BIG-IP Administrator is using Secure Copy Protocol (SCP) to transfer a TMOS image to the BIG-IP system in preparation for an upgrade. To what directory should the file be transferred?
Answer: A
Explanation:
BIG-IP systems require all ISO images (base TMOS images and HotFix images) to be stored in a specific directory used for software installation:
/shared/images/
This directory:
Is the only supported location from which the BIG-IP software installation system validates and installs ISO files Is accessible by both the GUI and TMSH installers Has adequate storage space allocated specifically for images Is part of the shared partition that persists across reboots When transferring images via SCP, the administrator must copy them directly into
/shared/images/ so that:
The GUI (System Software Management Available Images) can detect the image TMSH install software image commands can reference it Other directories such as /local/images/ or /var/images/ are not valid storage paths for software images.
NEW QUESTION # 47
An administrator is in the process of reactivating the license using the interface displayed in the exhibit.
What is the address of the license server to which the BIG-IP device must be able to establish an outbound connection in order to use theAutomatic Activation Method?
Answer: C
Explanation:
When you chooseAutomaticas the activation method in the License Re-activate screen, the BIG-IP device itself contacts F5'slicense activation serviceover the Internet.
For successful automatic activation:
* The BIG-IP must have outbound network connectivity (typically via the management interface).
* DNS resolution and routing must allow it to reach theF5 license activation host(the one shown in option D).
* The device sends its dossier and registration key to that service and receives an updated license file in return, which is then installed automatically.
The other hostnames in the options are not used by BIG-IP for license activation, so they cannot be correct in the context ofAutomatic Activation.
NEW QUESTION # 48
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?
Answer: A
Explanation:
For BIG-IP high-availability (HA) pairs, F5's recommended upgrade workflow prioritizes service continuity, predictable failover, and minimal 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
Option C exactly matches F5's documented production-safe upgrade method:
Upgrade the standby node first
Reboot into new image
Failover to upgraded device
Validate
Upgrade the remaining (now-standby) device
This procedure minimizes risk and traffic disruption.
NEW QUESTION # 49
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.

For BIG-IP high-availability (HA) pairs, F5's recommended upgrade workflow prioritizes service continuity
, predictable failover , and minimal downtime . The established best-practice sequence is:

Option C exactly matches F5's documented production-safe upgrade method:
* Upgrade the standby node 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 cause total outage , because both HA members would be unavailable at the same time.
NEW QUESTION # 50
For security reasons, a BIG-IP Administrator needs to specify allowable IP ranges for access to the Configuration Utility (WebUI).
The exhibit shows the User Administration section of the Configuration Utility.
The administrator could not find any setting that explicitly restricts access to the Configuration Utility.
Which one of the following is a reason for that?
Answer: C
Explanation:
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.
