Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:

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 Traffic

Used for traffic management settings, not logging.

C . System > Logs > Audit

Displays audit log settings and content but does not configure remote syslog destinations.

D . System > Configuration > Device

Used 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.

Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:

watch-devicegroup-device shows (among other columns) the commit ID (cid.id / shown here as clu_id), the originating device for that commit (cid-orig / shown here as cl_orig), and the time the configuration change was made (cid.time / shown here as cl_time). The highest/newest commit ID and its time represent the most recent configuration change seen among the devices. (clouddocs.f5.com)

bigip_a has the latest configuration (A) because it shows commit ID 3273 at 14:27:00, which is newer than commit ID 1745 at 13:52:34 on bigip_b and bigip_c. (clouddocs.f5.com)

Two devices are out of date (B) because bigip_b and bigip_c are still on the older commit ID 1745, so they do not match the latest commit shown on bigip_a. (clouddocs.f5.com)

Why the other options are not supported by this output:

C is not supported: bigip_c is not showing a newer commit than the others; it's on the older commit (1745), so it's not the source of the most recent change. The output's cid-orig column is what tells you where the change was made. (clouddocs.f5.com)

D/E are incorrect logic: matching cid.time between two devices only indicates they share the same change timestamp/commit, not that it is the correct or latest configuration. The ''latest'' is indicated by the newest commit ID/time (here, bigip_a). (clouddocs.f5.com)

Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:

In the BIG-IP Configuration Utility, status icons provide immediate health information. A red diamond specifically indicates that the object itself is administratively disabled. When a virtual server is disabled, BIG-IP will not accept or process traffic for that virtual server, regardless of pool or node state.

If all pool members were down, the virtual server would typically show a yellow triangle (available but no resources).

If all pool members were disabled, the virtual server would usually still be enabled but unavailable due to pool status, not shown as a red diamond.

Protocol mismatch (HTTPS sent to HTTP) does not change the administrative status icon of the virtual server.

Therefore, the red diamond clearly indicates the virtual server is disabled, making D the correct answer.

Comprehensive and Detailed Explanation From BIG-IP Administration Con10trol Plane Administration documents: Placing a device in the FORCED_OFFLINE state is a critical procedural concept for HA maintenance111213. 1415Unlike simply being 'Standby16', the FORCED_OFFLINE state ensures tha17t the Control Plane will not participate in failover selection, effectively preventing the device from becoming 'Active' even if the peer fails18. This state also allows the administrator to terminate existing connections to ensure no traffic is being processed during the maintenance window19.

Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:

BIG-IP supports remote authentication by integrating with centralized authentication services through its AAA framework. The supported and commonly used remote authentication servers include:

LDAP (A)

Used to authenticate users against directory services such as Active Directory or other LDAP-compliant directories.

RADIUS (C)

Commonly used for centralized authentication, authorization, and accounting, especially in network and security environments.

Why the other options are incorrect:

OAUTH (B) is an authorization framework, not supported as a direct administrative authentication backend for BIG-IP management access.

SAML (D) is primarily used for single sign-on (SSO) in application authentication scenarios, not for BIG-IP administrative login authentication.

Thus, the correct remote authentication server types are LDAP and RADIUS.
