az-305 Practice Question 1965
Exam: az-305
Domain: Design business continuity solutions
Topic: Design a solution for backup and disaster recovery
Difficulty: medium
Your company operates a global web application with multiple regions. You need to design a backup and disaster recovery solution that ensures an RPO (Recovery Point Objective) of less than 15 minutes and an RTO (Recovery Time Objective) of less than 1 hour. Which Azure services should you use to meet these requirements while minimizing costs and ensuring data is replicated across regions in case of a regional failure?
Answer Options
A
Azure Backup
B
Azure Geo-Replication (GRS) and Azure Recovery Services Vault
C
Azure Site Recovery
D
Azure File Sync
Correct Answer
B: Azure Geo-Replication (GRS) and Azure Recovery Services Vault
Explanation
The correct answer is B. Azure Geo-Replication (GRS) can achieve an RPO of less than 15 minutes by setting the replication interval to 1 minute or less. Azure Recovery Services Vault provides a cost-effective way to manage backups and can be used in conjunction with Geo-Replication to ensure data is replicated across regions. Option A (Azure Backup) alone does not provide cross-region replication, Option C (Azure Site Recovery) is more expensive and complex for this scenario, and Option D (Azure File Sync) is not suitable for disaster recovery purposes.
