Start Data Management Services And Vector Search PracticeYou are optimizing an Azure AI Search vector index with millions of documents. Users report high latency during vector queries. You decide to implement vector compression to reduce memory footprint and improve search throughput. Which compression method is natively supported in Azure AI Search?
Explanation: Azure AI Search natively supports Scalar Quantization (SQ) as a vector compression method, which reduces float32 vectors to int8, cutting memory footprint by roughly 4x with minimal recall loss. It is configured via a compression configuration referenced by the vector profile, and the field must be typed Edm.ByteCollection (or use the built-in rescoring/oversampling options) to store the quantized values.
You are developing a retrieval-augmented generation (RAG) solution using Azure AI Search. You need to configure a vector index to store 1536-dimensional embeddings generated by text-embedding-ada-002. Which parameter must you configure in the vector profile's algorithm configuration to use HNSW as the underlying approximate nearest neighbor algorithm?
Explanation: In Azure AI Search, the HNSW approximate nearest neighbor algorithm is selected by naming the algorithm configuration 'hnsw' in the vector profile's algorithm configuration. The vector profile references an algorithm configuration by name, and setting algorithm.name to 'hnsw' tells the search service to use the Hierarchical Navigable Small World graph for ANN search. This is the documented, supported value for enabling HNSW-based vector search.
You are configuring a vector search profile in Azure AI Search. Which TWO parameters are required when defining an algorithm configuration using the HNSW algorithm? (Choose two)
Explanation: When defining an HNSW algorithm configuration in Azure AI Search, the two required tuning parameters are efConstruction (option B) and m (option C). efConstruction sets the size of the dynamic candidate list during index construction, controlling the recall/quality versus build-time tradeoff, and it is a mandatory parameter of the HNSW parameters object. m specifies the number of bi-directional links created for each node in the HNSW graph, directly governing graph connectivity and recall, and it is likewise required. The other options do not belong: vectorDimensions (A) is a property of the vector field definition, not the HNSW algorithm configuration; compressionType (D) relates to vector compression/quantization settings rather than HNSW parameters; and shardCount (E) is a scaling/index-partition setting, not an HNSW algorithm parameter.
You are managing an Azure AI Search index that uses integrated vectorization with Azure OpenAI. When a user sends a query string, you want Azure AI Search to automatically vectorize the query text before performing the vector search. Which feature must you configure in the index schema?
Explanation: Integrated vectorization in Azure AI Search uses a vectorizer configuration connected to Azure OpenAI to automatically convert plain text queries into vector embeddings.
You are designing a multi-tenant AI application using Azure Cosmos DB for NoSQL. Each tenant has their own set of embeddings, and you need to filter vector search results strictly by tenantId while maintaining high query performance. How should you structure your vector index definition?
Explanation: For multi-tenant vector search in Cosmos DB for NoSQL, you should include tenantId in the container's standard indexing policy with a range index and filter using a WHERE clause alongside ORDER BY VectorDistance(). Cosmos DB can combine a scalar filter (tenantId) with the vector search, ensuring results are scoped to the tenant while still using the vector index for similarity ranking. This maintains performance and isolation without duplicating containers.
