Refer to the exhibit.

An application design has been proposed for a new infrastructure monitoring system that collects telemetry from infrastructure devices and visualizes it on a dashboard from a central database.

Because of constraints regarding available compute and storage at local sites, the decision has been made to implement a hybrid application design.

Which two changes must be made to the application architecture to improve the high availability and resiliency of the application, specifically to ensure minimal data loss of measurement data that is being collected periodically? (Choose two.)

Select all that apply.

• A

  Implement caching to reduce the amount of data that is sent from the cloud to local sites.

• B

  Implement certificates to ensure that data collection nodes are trusted sources in the application.

• C

  Implement local storage at the data collection layer in case of connectivity loss to the cloud.

• D

  Ensure that the database is replicated across multiple different cloud regions.

• E

  Implement a redundant network at the local sites.
