Which of the following statements regarding CMM deployment is FALSE?

The statement is false because the Nokia Cloud Mobility Manager (CMM) is a control plane Virtual Network Function (VNF), responsible for signaling and session management (e.g., MME in EPC, AMF in 5GC). These tasks are transaction-intensive but do not involve high-throughput user data packet forwarding. Technologies like SR-IOV (Single Root I/O Virtualization) and DPDK (Data Plane Development Kit) are specifically designed to accelerate data plane packet processing by bypassing the hypervisor and kernel network stacks. In the Nokia Cloud Packet Core solution, these technologies are utilized by the user plane VNF, the Cloud Mobile Gateway (CMG), not the CMM.

A. Hyperthreading and CPU pinning are standard and recommended performance optimization techniques for carrier-grade VNFs, including CMM, to guarantee dedicated CPU resources and prevent performance degradation from "noisy neighbors."
B. An anti-affinity rule is a fundamental high-availability (HA) feature in cloud environments. It is used to ensure that redundant instances of critical components, like the Nokia Elastic Cloud Controller (NECC), are placed on different physical hosts to avoid a single point of failure.
C. For a carrier-grade, geo-redundant deployment, which is a common requirement for production mobile core networks, deploying across two availability zones is a standard architecture to ensure service continuity in case of a site failure.

1. Nokia Cloud Packet Core Solution Description, Document ID: D578100234, Section: "Cloud Mobility Manager (CMM) VNF" and "Cloud Mobile Gateway (CMG) VNF". This document distinguishes the CMM as the control plane function and the CMG as the user plane function. It specifies that the CMG's user plane component (CMG-U) is optimized for high performance packet forwarding, which is where technologies like SR-IOV and DPDK are applied. The CMM's description focuses on signaling capacity and session management, with no mention of data plane acceleration.

2. Nokia Cloud Packet Core VNF and Solution Deployment Guide, Document ID: D578100237, Appendix: "VM Flavors". This guide provides detailed specifications for the virtual machines. The flavors for the CMG user plane (CMG-U) VMs explicitly require SR-IOV ports for data interfaces. In contrast, the flavors for CMM VMs specify standard VirtIO interfaces, confirming they do not use SR-IOV for packet processing.

3. Nokia Cloud Infrastructure (NCI) OpenStack Administrator Guide, Section: "Compute Host Configuration for VNF Workloads". This document details the recommended configuration for compute nodes hosting Nokia VNFs. It specifies enabling CPU pinning (isolcpus, tuned profiles) and managing hyperthreading to achieve the deterministic performance required by VNFs like CMM. It also describes the creation and use of server groups with anti-affinity policies for high-availability VNF deployments.
