Selected Answer: BD

To configure a partition key for container1 in Azure Cosmos DB, prioritizing characteristics that minimize the size of the partition and maintenance effort, you should prioritize the following two characteristics: B. High cardinality: Choosing a partition key with high cardinality means having a large number of unique values distributed across the dataset. This helps in distributing the data evenly across multiple partitions, preventing hotspots and ensuring efficient scalability. D. Static: Selecting a static partition key means choosing a key that does not frequently change. This minimizes the need for updates to the partition key value and reduces maintenance effort. It also helps in maintaining a consistent distribution of data across partitions over time. So, the correct answers are: B. High cardinality D. Static

B,D - considering products have category data, we can expect the category to be a filter, which makes it a good candidate to be a partition key. Categories are static known terms for a given business (values like "Electronics", "Clothing", "Wellness" etc)
