Which of the following sales scenarios does not require a separate maintenance service?

The question asks which scenario does not require a separate maintenance service purchase. This implies the service is included or bundled with the product's initial price. For some of Huawei's Digital Communication products, particularly in the lower to mid-range enterprise networking portfolio, a 1-year basic maintenance service is often included as part of the hardware purchase. This is not sold as a separate line item, simplifying the sales process for these products. The other options describe premium or long-term services that are always sold as separate, optional contracts.

B. Gold+ is a premium service level. It is always an upgrade sold separately from the standard server warranty and is not included by default.
C. Digital Solution products are complex, integrated systems. Their maintenance services are highly customized and are always defined and sold in a separate service contract or Statement of Work (SOW).
D. Storage products handle critical data, and multi-year standard or premium support (Standard+) is essential. These are always sold as separate, mandatory service contracts alongside the hardware.

1. Huawei Enterprise Business Warranty Policy. Section 2, "Warranty Policy for Specific Products." This policy document outlines that while most products have a basic hardware warranty, comprehensive maintenance services (Hi-Care) are sold separately. However, it notes exceptions for certain product lines where a limited service is bundled.

2. Huawei Enterprise Networking Product Data Sheets. Specific data sheets for certain AR G3 routers or S-series switches often list a "1-year basic software updates and support" as an included feature with the hardware purchase, distinct from separately purchased Hi-Care service packs.
