質問 # 35
The device is currently onv15.1.2.1.
The BIG-IP Administrator needs to boot the device back tov13.1.0.6to gather data for troubleshooting.
The system shows:
Sys::Software Status
Volume Product Version Build Active Status Allowed
HD1.1 BIG-IP 15.1.2.1 0.0.10 yes complete yes
HD1.2 BIG-IP 13.1.0.6 0.0.3 no complete yes
Which is the correct command-line sequence to boot the device to version13.1.0.6?
正解：C
解説：
To change the boot volume on a BIG-IP system from one installed TMOS version to another, the correct CLI tool is:
switchboot
The correct syntax uses the-bflag:
switchboot -b <volume>
This command marks the specified boot location as the one to be used on the next reboot.
Thus, to boot intoHD1.2which contains13.1.0.6, the sequence is:
* Mark HD1.2 as the next boot location:
* switchboot -b HD1.2
* Reboot the system:
* reboot
This is the standard and officially supported method for selecting a different installed volume.
Why the other options are incorrect:
A). "tmsh reboot HD1.2"
* There is no such tmsh syntax.
* Boot volume cannot be selected by adding a parameter to reboot.
C). switchboot -I HD1.2
* The -I flag is invalid. Only -b is used.
D). "tmsh switchboot HD1.2"
* switchboot isnota tmsh command; it is a system-level shell utility.
Therefore,Option Bis the correct and valid command sequence.
質問 # 36
Which of the following are resource allocation settings for modules? (Pick the 2 correct responses below)
正解：B、D
解説：
When provisioning modules on a BIG-IP system, F5 provides specific resource allocation settings that define how system resources -- CPU, memory, and disk -- are distributed to each licensed module. The two valid and officially recognised allocation settings are Nominal and Dedicated.
Nominal instructs the system to allocate a moderate, balanced share of resources to the module.
It allows the module to function effectively while sharing system resources with other provisioned modules. This is the most commonly used setting in multi-module deployments.
Dedicated allocates the maximum available system resources exclusively to a single module.
When this setting is applied, it is typically the only module provisioned, as it consumes resources at a level that prevents other modules from operating concurrently in a meaningful capacity.
質問 # 37
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?
正解：C
解説：
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 }
質問 # 38
Which two items demonstrate thecreation of a new volumefor software images?
(Choose two.)
正解：A、D
解説：
In BIG-IP, software images are installed onboot volumes(for example, HD1.1, HD1.2, HD1.3, etc.).
To install software on anew 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-volumekeyword
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 anexistingvolume only
* The GUI install dialog does not create new boot volumes
Thus, onlyOption AandOption Cproperly create a new software volume.
質問 # 39
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 do before the image is shown in the GUI under:
System > Software Management > Image List?
正解：B
解説：
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
