Which of the following maintenance service packages provide 7*10*ND spare parts pre-replacement (spare parts first) service? (Multiple choice)

Huawei's maintenance services define specific Service Level Agreements (SLAs) for hardware replacement. The "7x10xND" SLA, which means service requests are handled 7 days a week, 10 hours a day, with spare parts dispatched for Next Day delivery, is a feature of the premier-level service packages. According to Huawei's Hi-Care service descriptions, the Gold Medal (and its on-site variant, Gold+) tier provides this level of advanced hardware replacement. Standard and Silver tiers typically offer slower SLAs, such as 9x5xNBD (Next Business Day).

A, D: The Standard and Standard+ services typically provide a 9x5xNBD (Next Business Day) SLA, which is a lower service level than 7x10xND. B, E: The Silver and Silver+ services offer an intermediate SLA, which is better than Standard but does not typically align with the 7x10xND specification found in the Gold tier.
