Question 14 Discussion
Comments
Selected Answers: A
Selected Answers: B
When a BIG-IP Administrator changes module provisioning (such as adding ASM to a system previously provisioned only for LTM), the Traffic Management Microkernel (TMM) process is restarted.
TMM is responsible for traffic processing (LTM, ASM, AFM, etc.).
Provisioning changes require TMM to reload so the new module can be initialized.
This causes a brief traffic interruption, which is why module provisioning changes should be done during a maintenance window.
Why the other options are incorrect
❌ A. bd – Handles background system daemons, not traffic processing.
❌ C. sshd – Manages SSH access only.
❌ D. httpd – Manages the web-based Configuration Utility (GUI).
📌 Exam tip:
If the question involves traffic modules (LTM, ASM, AFM) → think TMM restart.
Selected Answers: B
When a BIG-IP Administrator changes module provisioning (such as adding ASM to an LTM-only system), the TMM (Traffic Management Microkernel) process restarts. This is because provisioning changes affect how system resources are allocated across modules, and TMM is the core traffic handling process that must be restarted to apply those resource allocation changes.
The BIG-IP system is provisioned for LTM only. The BIG-IP Administrator is tasked with provisioning ASM. What process restarts when the BIG-IP Administrator changes the module provisioning? (Choose one answer)
