A BIG-IP Administrator reviews the Plane CPU Usage performance chart and discovers a high percentage of Control Plane utilization. Which type of traffic does this indicate a higher usage of?

The correct answer is A. Administrative. High Control Plane CPU utilization on a BIG-IP system indicates an increased usage of administrative tasks and management traffic.

Why each option

High Control Plane CPU utilization on a BIG-IP system indicates an increased usage of administrative tasks and management traffic.

AAdministrativeCorrect

The Control Plane on a BIG-IP system is dedicated to managing the device itself, processing administrative tasks, configuration changes, and management traffic, which directly consumes its CPU resources.

BTunnel

Tunnel traffic, particularly user data within tunnels, is generally processed by the Data Plane (TMM) rather than the Control Plane.

CAccelerated ,

Accelerated traffic refers to traffic optimized for fast path processing, which occurs within the Data Plane and offloads work from the Control Plane.

DApplication

Application traffic, when processed for load balancing or security by the BIG-IP, is primarily handled by the Data Plane (TMM).
