A BIG-IP Administrator needs to load a UCS file but must exclude the license file.
How should the administrator perform this task? (Choose one answer)
A. From the GUI, select the UCS file and click Restore
B. From the CLI with command tmsh load /sys ucs <ucs filename>
C. From the CLI with command tmsh load /sys ucs <ucs filename> no-license
D. From the GUI, select the UCS file, uncheck the license box, and click Restore
正解:C
解説:
When restoring a User Configuration Set (UCS) file, BIG-IP allows administrators to selectively exclude the license during the restore process. From the CLI, this is accomplished using the no-license option with the tmsh load /sys ucs command.
The command:
tmsh load /sys ucs <ucs filename> no-license
restores:
* System configuration
* Certificates and keys
* Device and traffic objects
while explicitly excluding the license file, which is required when:
* Migrating configurations between devices
* Restoring to hardware with a different license
* Avoiding license conflicts or overwrites
Why the other options are incorrect:
* A does not provide the option to exclude the license.
* B restores the UCS including the license, which does not meet the requirement.
* D is incorrect because the BIG-IP GUI does not provide a checkbox to exclude the license during UCS restore.
Therefore, the correct and supported method is C.

The BIG-IP Administrator runs the command:
netstat -an | grep 443
and sees the following output:
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN
What does this output indicate about the service on port 443? (Choose one answer)
A. The service indicates no connections to the LISTEN port.
B. The service is in a standby state and unable to accept connections.
C. The service is actively listening on all interfaces for HTTPS traffic.
D. The service is actively listening only on the loopback interface.
正解:C
解説:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
In netstat output:
0.0.0.0:443 means the service is bound to all available IPv4 interfaces on the system.
LISTEN indicates the service is actively waiting for incoming connection requests.
Therefore, this output confirms that a service (commonly HTTPS/443, such as the BIG-IP Configuration Utility or an application listener) is actively listening on all interfaces, making B the correct answer.
Why the other options are incorrect:
A would show 127.0.0.1:443 if it were loopback-only.
C is incorrect because LISTEN explicitly indicates readiness to accept connections.
D is unrelated; standby state does not affect socket binding shown by netstat.
Hence, the correct answer is B.
質問 # 63
Which log file should the BIG-IP Administrator check to determine if a specific user tried to log in to the BIG-IP Configuration Utility? (Choose one answer)
A. /var/log/ltm
B. /var/log/httpd
C. /var/log/pam/tallylog
D. /var/log/secure
正解:D
解説:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:
On BIG-IP systems, all authentication attempts for administrative access-including logins to the Configuration Utility (GUI)-are logged in /var/log/secure. This log file records:
Successful and failed login attempts
The username used
The authentication method (local, LDAP, RADIUS, etc.)
Access denials and PAM authentication errors
Why the other options are incorrect:
/var/log/pam/tallylog tracks account lockouts and failed attempt counters, not detailed login attempts.
/var/log/ltm logs traffic management events, not administrative authentication.
/var/log/httpd logs web server activity but does not record authentication success or failure for BIG-IP administrative users.
Therefore, the correct log file to verify whether a user attempted to log in to the BIG-IP Configuration Utility is /var/log/secure.
質問 # 64
An LTM device has a virtual server mapped to www.f5.com. Users report that when they connect to /resources/201.1.2h.l_l.com they are unable to receive content. What is the likely cause of the issue?
A. The virtual address does not have ARP enabled.
B. The pool associated with the virtual server is falling its health check.
C. The virtual address does not have route advertising enabled.
D. The pool associated with the virtual server does not have priority group activation enabled.
正解:A
解説:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: The Control Plane is responsible for ARP (Address Resolution Protocol) management for Virtual Addresses. For a Virtual Server to be reachable, the BIG-IP must respond to ARP requests for that IP. If the "ARP" setting is disabled on the Virtual Address properties, upstream routers cannot resolve the MAC address of the BIG-IP, leading to connectivity failure even if the service itself is "Available."
質問 # 65
In which of the following log files would log events pertaining to pool members being marked "UP" or
"DOWN" by their Health Monitors be written? (Choose one answer)
A. /var/log/monitors
B. /var/log/audit
C. /var/log/ltm
D. /var/log/secure
正解:C
解説:
On BIG-IP systems, Local Traffic Manager (LTM) is responsible for:
* Pool and pool member management
* Health monitor execution
* Marking pool members UP or DOWN based on monitor results
Events related to health monitor status changes, including when pool members transition between UP and DOWN, are logged in /var/log/ltm.
Why the other options are incorrect:
* /var/log/audit records administrative configuration changes, not runtime health status.
* /var/log/secure logs authentication and authorization events.
* /var/log/monitors is not a standard BIG-IP log file.
Therefore, the correct log file for pool member health monitor status events is /var/log/ltm.
