An administrator is troubleshooting a BIG-IP that is experiencing intermittent management API timeouts. The `tmsh show sys cpu` command shows the management CPU at 90% utilization, while TMM CPU is at 20%. Which metric should the administrator investigate further?

The hardware acceleration statistics

The rate of configuration sync operations

The number of active TMM connections

The throughput on the data plane interfaces

A BIG-IP administrator is planning to deploy a new iRule that requires a large lookup table to be loaded into memory. The table is used for every request. Which resource should the administrator monitor to ensure the iRule does not cause performance degradation?

The disk I/O on the management partition

A BIG-IP is configured with a high volume of iRules that perform complex string manipulation on every HTTP request. The administrator notices that the management interface becomes sluggish during peak traffic, and `tmsh show sys tmm-info` indicates TMM CPU is at 95%. What is the most likely cause of the management interface sluggishness?

The iRules are consuming control plane CPU for processing

The control plane is performing SSL handshakes for the iRules

The iRules are writing excessive logs to the management partition

TMM CPU saturation is starving the control plane of CPU cycles

A BIG-IP is configured with a large number of SNMP traps and syslog messages being sent to external monitoring systems. The administrator notices that the TMM CPU is at 30% but the management CPU is at 85%. Which action would most effectively reduce the management CPU load?

Increase the logging level to capture more details

Move the SNMP agent to the data plane

Enable hardware acceleration for SNMP processing

Reduce the frequency of SNMP traps and syslog messages

Which resource is specifically used by the data plane on an F5 BIG-IP to accelerate packet processing?

Hardware acceleration (e.g., ASICs or FPGAs)
