20+ practice questions focused on Control Plane Administration — one of the most tested topics on the F5 Certified Administrator: Control Plane Administration exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Control Plane Administration PracticeWhich TWO actions should an administrator perform to properly secure the F5 control plane against unauthorized local user access?
Explanation: Hardening the control plane requires both removing default attack vectors and ensuring robust authentication mechanisms. Disabling the default 'admin' password and using strong authentication ensures that unauthorized users cannot guess credentials, while implementing password complexity policies prevents brute-force success. These steps are fundamental to administrative security, as they protect the system's management credentials from being compromised by automated scripts or persistent attackers looking for default configurations.
An administrator wants to audit all CLI commands executed by users on the BIG-IP system. Which feature should be configured to ensure comprehensive logging of administrative actions?
Explanation: Auditing is a cornerstone of control plane management. By enabling the bash auditing feature, the system logs every command executed in the shell to the syslog facility. This provides a forensic trail of administrative activity. Ensuring these logs are forwarded to a centralized logging server is vital for compliance and incident response, allowing administrators to review activities performed on the system during potential security incidents.
Which THREE items are considered part of the BIG-IP control plane and should be regularly backed up to ensure disaster recovery?
Explanation: Backing up the control plane is vital for recovering from system failure. The UCS file, configuration archives, and SSL certificates represent the core of the system configuration. Without these, restoring a device to its operational state is impossible. Administrators must ensure these are stored securely off-box to meet recovery time objectives, as they contain the identity, security posture, and logical topology required for the unit to function.
Refer to the exhibit. An administrator attempts to run 'tmsh show sys hardware' but receives no output. What is the most likely cause for this behavior?
Explanation: The failure to display hardware information suggests a disruption in the control plane communication with the underlying hardware abstraction layer or the system's management processes. This often indicates a corrupted process or a failure in the communication pipeline between the tmsh CLI and the system hardware monitors. It is a serious indicator that the management plane is degraded, requiring immediate investigation of service health.
Which THREE factors are required to successfully establish trust between BIG-IP systems for device service clustering (DSC)?
Explanation: Establishing a trust relationship is the foundation of HA clustering. It requires a mutual exchange of device certificates, ensuring that each system can verify the identity of its peers. Without proper trust, the systems cannot securely synchronize configurations or perform stateful failover. This process is essential for maintaining a secure and reliable HA cluster, as it prevents unauthorized devices from joining or interfering with the operational cluster.
