Salesforce Certified Data Architecture Practice Test

What is the recommended solution for ensuring access to current and historical data from IoT technology implemented by Universal Containers?

1. Create new custom fields for temperature and humidity in the existing Container custom object.

2. Create a new Container Reading custom object that is updated when a measure is received for a specific container.

3. Utilize Salesforce's standard objects to record all temperature and humidity data.

4. Log data updates in an external database to maintain a history.

The correct answer is: Create a new Container Reading custom object that is updated when a measure is received for a specific container.

Creating a new Container Reading custom object that is updated when a measure is received for a specific container is the most effective solution for ensuring access to current and historical data from IoT technology. This approach allows for a structured way to capture and store each measurement as a record in a dedicated object, which is essential for analyzing trends over time and maintaining a clear historical record. By using a custom object, the organization can easily accommodate various data points, such as temperature and humidity, as separate records associated with their respective containers. This design not only ensures that each measurement is stored independently but also allows for easier reporting and querying of historical data. For instance, comparisons between different readings or analysis over specific intervals can be performed efficiently. The other options present limitations. Implementing custom fields within the existing Container custom object would lead to data overcrowding and could complicate the structure, making it less flexible for future data points. Utilizing standard objects may restrict the customization needed to capture and report IoT data effectively. Logging data updates in an external database would complicate data access and consistency since integrating external systems with Salesforce can pose challenges in real-time data synchronization and reporting. By opting for a dedicated Container Reading object, the system design remains clean, organized, and aligned with best
