Huawei Cloud El builds enterprise intelligence services based on three-tier services. Which of the following options does not belong to Layer 3 services?

Question

Options

• ABasic platform services
• BGeneral domain services
• CIndustry sector services
• DIntegration services

• A
  12% (2)
• B
  6% (1)
• C
  6% (1)
• D
  76% (13)

Explanation

Option D (Integration services) is correct because Huawei Cloud EI's three-tier framework consists specifically of Basic platform services (Tier 1), General domain services (Tier 2), and Industry sector services (Tier 3) - "Integration services" is not one of the defined tiers and does not exist as a named layer in this architecture.

Options A, B, and C are distractors precisely because they are the three legitimate layers: Basic platform services form the foundational AI/ML infrastructure at the base, General domain services sit in the middle providing cross-industry AI capabilities, and Industry sector services sit at the top delivering vertical-specific solutions for sectors like finance, healthcare, and manufacturing.

Memory tip: Think of the three tiers as a pyramid - Basic → General → Industry (bottom to top), or remember the acronym BGI. Any answer that introduces a concept outside this pyramid (like "Integration") is the odd one out.
