An e-commerce platform processes customer orders and requires zero data loss in the event of a regional outage. The platform uses a primary database in one Azure region and replicates to a secondary region. Which replication mode should the database administrator choose to guarantee that every committed transaction is available at the secondary site before the primary acknowledges the transaction?

Log shipping with delayed apply

A software development team uses a virtual machine (VM) to test new application builds. Before applying a major configuration change, the team wants to be able to revert the VM to its current state quickly if the change causes problems. The VM is running and cannot be shut down. Which recovery approach should the team use?

Perform a full backup of the VM to a separate storage account

Enable asynchronous replication to another region

Move the VM to a warm disaster recovery site

Create a snapshot of the VM before making the change

A database administrator is restoring a production database from a full backup taken 12 hours ago and a differential backup taken 2 hours ago. After restoring both backups, the database is online, but the administrator notices that transactions from the last 2 hours are missing. What is the most likely cause of the missing transactions?

The differential backup was restored before the full backup

Transaction log backups taken after the differential backup were not restored

The database was restored in simple recovery mode

The full backup was taken after the differential backup

Why is it important to regularly test data recovery strategies?

To reduce the cost of backup storage

To eliminate the need for offsite backups

To guarantee that no data loss will occur during a disaster

To ensure that the recovery plan works and personnel are familiar with their roles

A hospital's electronic health record (EHR) system must have zero data loss in the event of a primary data center failure. The system is hosted on two virtual machines in different availability zones. Which replication strategy should the disaster recovery architect implement for the EHR database?

Daily full backups to the secondary site

Asynchronous replication with a 5-minute replication interval

Snapshot replication every 15 minutes

Synchronous replication to the secondary availability zone
