To ensure that all data for the current year is available in Azure Time Series Insights (TSI), you should set a value for the Data retention time setting. Therefore, the correct answer is B.

Azure Time Series Insights is a fully managed analytics, storage, and visualization service that makes it simple to explore and analyze billions of IoT events simultaneously. Data retention time setting is used to define the period for which the data will be stored in the TSI environment. This setting specifies how long data is kept in TSI's warm store, which is a cache of data that can be quickly queried for visualization and analysis.

By default, Azure Time Series Insights keeps data for seven days in the warm store, after which it moves to the cold store. The cold store is designed to store data for long-term retention and is optimized for low-cost storage. Data is kept in the cold store until it expires or is deleted by the user.

To ensure that all data for the current year is available, you should adjust the Data retention time setting to a value that covers the current year. For example, if the current year is 2023, you could set the Data retention time to 365 days (or 366 if it is a leap year) to ensure that all data for the current year is available. This means that data will be kept in the warm store for the entire year, and then move to the cold store for long-term retention.

Options A, C, and D are not directly related to the scenario described in the question. Adding a disaster recovery (DR) strategy, changing the pricing tier, or creating a reference data set may be necessary for other reasons but are not required to ensure that all data for the current year is available in Azure Time Series Insights.
