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Two devices are out of date (B) because bigip_b and bigip_c are still on the older commit ID 1745, so they do not match the latest commit shown on bigip_a.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 Administration20 Control Plane Administration documents: Connectivity management involves ensuring that the physical layer matches the networking environment. Interface properties, including media speed, duplex settings, and MTU, are managed at the Control Plane level under the Network menu. To resolve a mismatch with an upstream switch, the administrator must navigate to Network > Interfaces to manually override auto-negotiation settings.

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.

===========

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.
