The exhibit shows the configuration of aSelf IPwith:
* Port Lockdown: Allow Custom
* ACustom Listthat includes the following TCP ports:
* 443
* 22
Meaning of these ports:
* TCP 443# HTTPS (TMUI - web-based management)
* TCP 22# SSH (command-line remote access)
No other TCP, UDP, or protocol entries are listed; therefore, only these two services are allowed to reach the BIG-IP via this Self IP.
Evaluating the answer choices:

Thus,SSHis the only traffic permitted through this Self IP configuration.

Licensing the system is the first step to activate the features and allow you to begin configuring the device.

The command shown in the exhibit replaces the SSH allow list with 10.0.0.0/24, which permits any address from 10.0.0.1 through 10.0.0.254; 10.0.0.256 is not a valid IPv4 address, and the
100.0.1.10 / 100.0.0.10 addresses are outside that subnet.

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.

The HTTPD allow list controls which IP addresses or subnets may access the Configuration Utility (TMUI) on the BIG-IP system. The Administrator already has two subnets allowed and needs to add asingle host IPto the existing list.
* The object/sys httpd allowsupports actions such asadd,delete, andreplace-all-with.
* Because the goal is toaddone more entry without removing the existing permitted subnets, the correct command is:
modify /sys httpd allow add { 172.28.32.22 }
This appends the new host to the existing list while preserving the previously configured networks.
Why the other options are incorrect:
* Option A (replace-all-with)wouldoverwritethe entire allow list, removing existing permitted subnets- unacceptable.
* Option B (delete)wouldremovethe existing networks and not add the required host.
Therefore, the correct administrative action is toaddthe jump host's IP.
