An organization is planning to upgrade a BIG-IP system from 16.1.x to 17.1.x.
For a successful upgrade, the Service Check Date must be equal to or newer than the License Check Date required for 17.1.x.
Which command will show the Service Check Date on the BIG-IP system being upgraded?
BIG-IP licensing information, including the Service Check Date, is stored in the file:
/config/bigip.license
This file contains all license attributes downloaded from the F5 licensing server, including:
License key
Licensed modules
Useful life date
Service check date
The Service Check Date determines whether the system is eligible for upgrades to specific TMOS versions. When reviewing upgrade readiness, administrators extract this value directly from the license file with:
grep 'Service check date' /config/bigip.license
Why the other options are incorrect:
/config/bigip.conf stores BIG-IP configuration objects, not license metadata.
/config/svc_chk_date.dat is not a valid file in the licensing system; it does not contain license parameters.
/config/BigDB.dat stores internal database values, not licensing attributes.
Thus, only the bigip.license file contains the correct licensing information required for verifying upgrade eligibility.
The BIG-IP Administrator received a ticket that an authorized user is attempting to connect to the Configuration Utility from a jump host and is being denied.
The HTTPD allow list is configured as:
sys httpd {
allow { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 }
}
The jump host IP is 172.28.32.22.
What command should the BIG-IP Administrator use to allow HTTPD access for this jump host?
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 a single host IP to the existing list.
The object /sys httpd allow supports actions such as add, delete, and replace-all-with.
Because the goal is to add one 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) would overwrite the entire allow list, removing existing permitted subnets---unacceptable.
Option B (delete) would remove the existing networks and not add the required host.
Therefore, the correct administrative action is to add the jump host's IP.

An administrator is in the process of reactivating the license using the interface displayed in the exhibit.
When you choose Automatic as the activation method in the License Re-activate screen, the BIG-IP device itself contacts F5's license activation service over 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 the F5 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 of Automatic Activation.
When logged into the bash shell of a BIG-IP system, which of the following commands will display the management-ip address?
(Choose two.)
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.
Why the other options are incorrect:
B . show mgmt ip
Not a valid bash or tmsh command on BIG-IP.
D . list / sys management-ip
Missing the tmsh prefix.
In bash, this will generate a syntax error.
The correct form requires:
tmsh list /sys management-ip
When using the tmsh shell of a BIG-IP system, which command will display the management-ip address?
Comprehensive and Detailed Explanation (Paraphrased from F5 BIG-IP Administration / Installation / Initial Configuration concepts)
Within the BIG-IP Traffic Management Shell (tmsh), system configuration objects---including the management IP---are organized under the /sys hierarchy. The management IP address is a configurable property stored in the system configuration and can be viewed using the tmsh list command, which displays configuration objects and their currently assigned values.
Why ''list /sys management-ip'' is correct
The list command in tmsh is used to display configured system values, not runtime statistics.
The object that holds the management IP settings on BIG-IP systems is located at:
/sys management-ip
Running the command:
list /sys management-ip
will reveal the settings for the management IP interface, including the address, netmask, and any associated attributes.
This is the standard method used during system setup and verification to confirm the management IP configuration.
This behavior aligns with BIG-IP administration procedures, where configuration information is retrieved using list, while operational data is retrieved using show.
Why the other options are incorrect
A . run /util bash ifconfig mgmt
This command enters the Bash shell, then runs ifconfig to display the management interface.
While this can show the management interface address, it is not a tmsh-native command, and the question specifically asks for a tmsh command.
Administrators use tmsh directly for configuration display rather than leaving the shell.
C . show /sys management-ip
The show command displays statistics or operational data, not configuration values.
The management-ip object does not maintain statistics; therefore show does not return the configuration details required.
Only the list command reveals stored configuration data such as IP address and netmask.
