The SAP Quick Sizer is the official and mandatory tool provided by SAP for calculating the hardware requirements for SAP applications before installation. When planning a migration to SAP Business Suite on SAP HANA on Azure virtual machines (an IaaS scenario), this tool is used to estimate the necessary CPU (SAPS), memory, and disk resources based on business inputs like user numbers and transaction volumes. This ensures the selected Azure VM types meet the performance and capacity needs of the planned SAP system, which is a critical step in the planning and deployment phase.

A. SAP Quick Sizer for HANA Cloud: This is incorrect because SAP HANA Cloud is a distinct Database-as-a-Service (DBaaS) offering. The question specifies deploying on Azure virtual machines, which is an Infrastructure-as-a-Service (IaaS) model.

B. SAP Cloud Platform Cockpit: This is a management and administration interface for the SAP Business Technology Platform (BTP), not a tool for sizing infrastructure for SAP applications.

C. HANA Cockpit: This is an administration and monitoring tool used after an SAP HANA database has been deployed. It is not used for pre-migration sizing calculations.

" under the "Sizing SAP systems" section

it states

"For sizing of SAP systems

SAP requires using the SAP Quick Sizer tool." This document provides guidance for deploying SAP workloads on Azure

which is the scenario in the question.

but the principle and tool are the same) states

"The SAP Quick Sizer tool has been developed by SAP in close cooperation with its platform partners to help you determine the hardware requirements for your SAP applications."
