iMaster NCE-Campus supports multiple deployment modes to meet the needs of different enterprise customers, including on-premise deployment, MSP-owned cloud deployment, and Huawei public cloud deployment. The choice of deployment mode mainly depends on whether the customer wants to invest in infrastructure, manage the platform independently, or use a fully hosted service.

In this scenario, the supermarket chain explicitlydoes not want to purchase physical servers or software, which means an on-premise deployment is not suitable. On-premise mode requires customers to prepare hardware resources, install software, and maintain the system themselves. Similarly, an MSP-owned cloud deployment typically involves a managed service provider hosting the platform, which may still require contractual dependency on a third party and is not the most straightforward option for enterprises seeking minimal investment and simplified operations.

According to HCIP Datacom Campus Network documentation, theHuawei public cloud deploymentis recommended for customers who want acloud-based, subscription-oriented solution. In this mode, iMaster NCE-Campus is hosted and operated on Huawei Cloud. Customers only need to register and subscribe to the service, without purchasing servers, storage, or management software. Huawei is responsible for system maintenance, upgrades, security, and high availability.

This deployment model is especially suitable forretail chains and multi-branch enterprises, such as supermarkets, because it enables centralized management of geographically distributed branch networks with low initial investment and fast rollout.

Therefore, the recommended deployment mode in this case isHuawei public cloud, making optionCthe correct answer.
