問題 #26
How should a BIG-IP Administrator check the provisioned CPU percent for a module? (Choose two.)
答案：B,D
解題說明：
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.
問題 #27
An F5 BIG-IP Administrator is asked to report which modules are provisioned on the BIG-IP. In which two ways can this be done? (Choose two.)
答案：A,B
解題說明：
Provisioning determines:
Which BIG-IP modules are enabled (LTM, ASM, APM, AFM, DNS, etc.)
Their provisioning levels (None, Minimal, Nominal, Dedicated)
Two accurate ways to view provisioning settings are:
A). GUI -- System -> Resource Provisioning -> Module Allocation
This is the primary GUI screen showing:
All modules
Their provisioning level
System resource distribution impact
Administrators commonly use this page to confirm or change module provisioning.
D). TMSH -- list /sys provision
This tmsh command displays each module and its provisioning level:
sys provision ltm { level nominal }
sys provision asm { level none }
...
This is the authoritative CLI method for checking module provisioning configurations.
問題 #28
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.)
答案：B
解題說明：
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.
問題 #29
The Port Lockdown feature prevents unwanted connection attempts to a Self IP.
Which three types of connection attempts areunaffectedby Port Lockdown settings?
答案：C
解題說明：
Port Lockdown controls which ports and protocols aSelf IPwill respond to.
However, certain traffic types bypass Port Lockdown for BIG-IP functionality and routing integrity.
The three types that areNOT affectedby Port Lockdown are:
1. Defined Virtual Server Traffic
Traffic destined to a Self IP that matches aconfigured virtual serveris always accepted by the BIG-IP, regardless of Port Lockdown settings.
This ensures that traffic processing does not break when administrators restrict Self-IP ports.
2. ICMP (Internet Control Message Protocol)
ICMP (such as ping, traceroute responses, etc.) always passes through a Self IP even when Port Lockdown is set to:
* Allow Default
* Allow None
* Allow Custom
F5 allows ICMP for reachability and diagnostic purposes independent of Port Lockdown rules.
3. Centralized Management Infrastructure (CMI)
CMI includes the internal HA services used for:
* Device Trust
* ConfigSync
* Failover
* Mirroring
These essential HA communications bypass Port Lockdown to prevent accidental cluster failure.
The well-known port for this traffic isTCP 4353, which is always permitted.
Why the other options are incorrect:
Option A:SSHisrestricted by Port Lockdown unless explicitly allowed.
Option B:Same issue - SSH does not bypass Port Lockdown.
OnlyDefined VS Traffic,ICMP, andCMIbypass Port Lockdown.
問題 #30
Refer to the exhibit.
An organization has purchased a BIG-IP license that includes all available modules but has chosen to provision only the modules they require.
The exhibit displays the current resource allocation from theSystem # Resource Provisioningpage.
Based on the information provided, which F5 modules have been provisioned?
答案：C
解題說明：
The exhibit shows theCurrent Resource Allocationfor:
* CPU
* Disk
* Memory
In particular, theMemory Allocationbar displays the modules that are currently provisioned.
Memory is the most reliable indicator because BIG-IP allocates memoryonlyto modules that are actively provisioned.
From the exhibit:
* MGMT(Management) - always present
* TMM(Traffic Management Microkernel) - indicatesLTM is provisioned
* GTM- this label indicates that theDNS moduleis provisioned (GTM = Global Traffic Manager, now called DNS)
* APM- explicitly shown, indicatingAccess Policy Manageris provisioned
Therefore, the provisioned modules are:
* LTM(implied by TMM allocation)
* DNS/GTM
* APM
This matchesOption C: LTM, DNS, APM.
