NEW QUESTION # 51
Given thatBIGIP-<version>.isoandHotfix-BIGIP-<version>-ENG.isohave been uploaded to/shared/images on an F5 device, what is the appropriatetmshcommand to prepare and update the BIG-IP device with the hotfixof a software version on anew volume HD1.2?
(Choose one.)
Answer: A
Explanation:
When installing a BIG-IP software versionwith a HotFixon anew boot volume, F5 requires that both thebase TMOS imageand theHotFix imagebe installed together as part of the same installation workflow.
The correct process is:
* Specify thebase TMOS ISO
* Specify theHotFix ISOthat corresponds to that base version
* Instruct the system tocreate 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 onHD1.2
* 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.
NEW QUESTION # 52
The BIG-IP Administrator needs to update access to the Configuration Utility to include the
172.28.31.0/24 and 172.28.65.0/24 networks. From the TMOS Shell (tmsh), which command should the BIG-IP Administrator use to complete this task?
Answer: C
Explanation:
Access to the BIG-IP Configuration Utility (TMUI) is controlled through the /sys httpd allow list.
This list defines which IP addresses or subnets are allowed to connect to the management web interface.
To allow two new subnets--172.28.31.0/24 and 172.28.65.0/24--the administrator must add both subnets to the existing list without removing current entries.
In tmsh, subnet entries must be specified in network/netmask format, for example:
172.28.31.0/255.255.255.0
The correct tmsh command to append these networks is:
modify /sys httpd allow add { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 }
NEW QUESTION # 53
When logged into the bash shell of a BIG-IP system, which of the following commands will display the management-ip address? (Choose two.)
Answer: A,B
Explanation:
When logged into the bash shell of a BIG-IP system, there are two valid ways to view the management-ip address:
A). tmsh list /sys management-ip
Even from the bash shell, the administrator can enter a tmsh command by typing:
tmsh list /sys management-ip
This displays:
Management IP address
Netmask
Any configured management routes
This is the official tmsh method for viewing the management-ip configuration.
C). ifconfig mgmt
In the underlying Linux OS, the management interface maps to the mgmt interface.
Running:
ifconfig mgmt
displays:
Assigned management IP
Netmask
Link-level status
This is a valid Linux-level method used frequently for troubleshooting.
NEW QUESTION # 54
The BIG-IP Administrator uses Secure Copy Protocol (SCP) to upload a TMOS image to the/shared/images/ directory in preparation for a TMOS upgrade.
After the upload is completed, what will the system dobeforethe image is shown in the GUI under:
System ยป Software Management ยป Image List?
Answer: A
Explanation:
When a TMOS image (.iso file) is uploaded into the/shared/images/directory, the BIG-IP performs an internal validation step before the ISO appears in the GUI.
1. The system verifies the internal checksum
* BIG-IP automatically reads the embedded checksum inside the ISO file
* Verifies integrity of the uploaded image
* Confirms the file is not corrupted or incomplete
* Ensures the image is a valid F5 TMOS software image
Only after this checksum verification succeeds does the image appear under:
System # Software Management # Image List
Why the other options are incorrect:
A). The system performs a reboot into a new partition
* Uploading an ISO file never triggers a reboot.
C). The system copies the image to /var/local/images/
* All valid TMOS images remain in/shared/images/.
* No copying occurs.
NEW QUESTION # 55
A BIG-IP device will be dedicated to functioning as a WAF, requiring only the ASM module to be provisioned.
What provisioning level will ensure that the system allocates all CPU, memory, and disk resources to this module exclusively?
Answer: A
Explanation:
Provisioning defines how BIG-IP allocates system resources to modules.
The provisioning levels include:
* Dedicated - allocates all CPU, memory, and disk resources to a single module
* Nominal - standard resource allocation balanced with other modules
* Minimal - lowest level, used for basic utility needs
* None - module disabled
* Comprehensive / Maximal - not valid TMOS provisioning levels
Why "Dedicated" is correct
When a BIG-IP device is intended to run only ASM (Web Application Firewall), the recommended way to maximize performance is to provision the module at Dedicated level.
With ASM: Dedicated :
* ASM receives the entire hardware capacity
* No other modules can or should be provisioned
* This is explicitly recommended when a device is used solely as a WAF platform Why other options are incorrect B). Comprehensive / C. Maximal
* These are not valid provisioning modes in BIG-IP.
* TMOS supports: Nominal, Minimal, Large (module-specific), and Dedicated.
D). Nominal
* Shares resources with other modules
* Does not provide full system performance
* Not suitable when exclusive resource allocation is required
Thus, Dedicated is the correct provisioning choice.
