The exact extract asks for the positions included in the Digital Power Partner specialist certification. The selected answer is A, B, C, D because the certification framework covers multiple partner-facing job roles, not only sales. Marketing capability is needed because partners must understand market promotion, customer awareness, campaign execution, and business development. Field capability is included because partner specialists may need practical onsite or execution understanding. Sales capability is required because Huawei partner certification validates whether partners can identify opportunities, position Smart PV solutions, and support commercial conversion. Presales capability is also essential because Smart PV solutions require technical solution design, scenario matching, configuration awareness, and value explanation before the deal is closed. Therefore, all four listed positions belong to the partner specialist certification scope. Reference: Huawei HCSA-Sales-Smart PV V2.0 Partner Policies Outside China training extract.
