F5CAB4 Exam Dumps : BIG-IP Administration Control Plane Administration (F5CAB4) exam

On a BIG-IP system, remote syslog server configuration is managed through the logging configuration framework. In the Configuration Utility, this is accessed via:

System > Logs > Configuration

This section allows the administrator to:

Define remote syslog destinations

Configure log publishers

Control which log types (system, audit, LTM, ASM, etc.) are forwarded to external syslog servers

Why the other options are incorrect:

A. System > Configuration > Local TrafficUsed for traffic management settings, not logging.

C. System > Logs > AuditDisplays audit log settings and content but does not configure remote syslog destinations.

D. System > Configuration > DeviceUsed for device-level settings such as hostname and platform configuration, not logging.

Therefore, the correct location to reconfigure BIG-IP to send logs to new syslog servers is System > Logs > Configuration.

===========

On a BIG-IP system, NTP (Network Time Protocol) configuration is part of the system-level configuration settings. In the Configuration Utility, NTP servers are configured under the System configuration hierarchy.

The correct navigation path is:

System > Configuration > Device > NTP

This location allows the administrator to:

Add, modify, or remove NTP servers

Ensure accurate system time synchronization

Maintain proper time alignment required for features such as ConfigSync, HA failover, logging, and certificate validation

Why the other options are incorrect:

A. System > Platform is used for hardware-related settings.

B. System > Preferences manages UI and user preferences.

C. System > Services controls system daemons and services, not time configuration.

Therefore, the correct answer is D. System > Configuration.

===========

When BIG-IP is configured to use remote authentication (such as LDAP), all authentication and authorization attempts—including successes and failures—are logged to /var/log/secure.

For LDAP-based administrative login issues, /var/log/secure contains:

LDAP authentication failures

PAM authentication errors

Authorization and access-denied messages

Details explaining why a remote user could not log in

Why the other options are incorrect:

/var/log/user.log is not a standard BIG-IP log file for authentication.

/var/log/ltm logs traffic management events, not user authentication.

/var/log/messages contains general system messages but not detailed authentication failure information.

Therefore, the correct log file to troubleshoot LDAP administrative login failures is /var/log/secure.
