What is a primary function of backup replicas?

To perform data analysis
To act as an immediate restore option
To improve application performance
To provide an alternative data store

The correct answer is: To provide an alternative data store

A primary function of backup replicas is to provide an alternative data store. Backup replicas create copies of data or systems that can be used in the event of data loss, corruption, or system failure. This ensures that there is a reliable, up-to-date source of data that can be accessed to restore operations swiftly, minimizing downtime and data loss. While providing an alternative data store is key for recovery purposes, the other options do not align with the primary objectives of backup replicas. Performing data analysis typically involves more active datasets that are used for processing and insights rather than for recovery. An immediate restore option can be part of using backup replicas, but the core concept focuses on having a separate, safe copy of data rather than just highlighting its restoration capability. Improving application performance can be influenced by various factors, but it is not the main purpose of backup replicas, which primarily serve as a safeguard for data integrity and availability.
