Question 7
Domain 2: Implement Knowledge Mining and Azure AI Search SolutionsYour Azure AI Search semantic search implementation is not available even though it's configured. You're using the Basic tier. What is the cause?
Correct answer: B
Explanation
Azure AI Search semantic search is not supported on the Basic tier. Microsoft states that semantic search is available only on the "Standard S1 tier or higher," so a Basic service will not expose that feature even if it is configured.
Why each option is right or wrong
A. Semantic search requires at least 50,000 documents indexed
B. Semantic search is only available on Standard S1 tier or higher
Azure AI Search semantic ranking is a paid feature that is only exposed on Standard S1 and above; the Basic SKU does not include it, so a service on Basic will not surface semantic search at runtime even if the configuration is present. Microsoft’s service tier matrix limits semantic search to Standard S1, S2, S3, and higher-capacity tiers, making the Basic tier the blocking condition here.
C. Semantic search requires vector fields in the index
D. Semantic search must be enabled in the Azure portal settings first
