Correct Answer: A

The indexing policy has an includedPaths array that contains only one path:

/product/brand/ . This means that only the properties under /product/brand will be indexed.

The symbol indicates that only scalar values will be indexed, not arrays or objects1.

The excludedPaths array contains a single path: /* .

This means that all other properties will be excluded from indexing.

The * symbol indicates a wildcard that matches any property name1.

Therefore, the paths /product/category , /product/[ ]/category , and /product/brand/tailspin will not be indexed.

Correct Answer: DE

Explanation:

Connecting to a preferred region using the API for NoSQL

The SDKs accept an optional parameter PreferredLocations that is an ordered list of Azure regions.

The SDK will automatically send all writes to the current write region. All reads will be sent to the first available region in the preferred locations list. If the request fails, the client will fail down the list to the next region.

The SDK will only attempt to read from the regions specified in preferred locations. So, for example, if the Azure Cosmos DB account is available in four regions, but the client only specifies two read(non-write) regions within the

PreferredLocations, then no reads will be served out of the read region that is not specified in PreferredLocations. If the read regions specified in the PreferredLocations list are not available, reads will be served out of write region.
