   What is the main difference between backup and replication in cloud BCDR?

   • ABackup is only for databases, while replication is for all data types
   • BBackup is automated, while replication requires manual intervention
   • CBackup is used for long-term archival, while replication is used for short-term recovery
   • DBackup creates point-in-time copies for restoration, while replication continuously copies data to a secondary location

   A company runs a multi-tier application in a cloud region. The application uses a load balancer, web servers, and a database. The company wants to automate failover to a secondary region in case of a regional outage. The failover must also ensure that the database is consistent and that no data is lost. Which approach should the company take?

   • AUse a database replication solution with synchronous replication to the secondary region and an orchestration runbook that starts the application stack and updates DNS.
   • BTake hourly backups and restore them in the secondary region, then update DNS automatically.
   • CUse asynchronous replication to the secondary region and manually start the application stack during a disaster.
   • DUse a multi-region load balancer that routes traffic to the secondary region, but keep the database in the primary region.

   How does recovery point objective (RPO) influence BCDR planning?

   • AIt determines the minimum number of backup copies that must be stored offsite
   • BIt determines the maximum acceptable amount of data loss, which influences backup frequency and replication strategy
   • CIt defines the maximum cost that can be spent on backup storage
   • DIt specifies the maximum time allowed to restore services, which influences the choice of recovery site

   Why is disaster recovery (DR) important in a cloud environment?

   • AIt provides a structured approach to restoring cloud services and data after a disruptive event
   • BIt ensures that data is encrypted both at rest and in transit
   • CIt reduces the monthly cost of cloud resources by using reserved instances
   • DIt automatically prevents all service disruptions from occurring

   In cloud disaster recovery, when is a cold site most appropriate?

   • AWhen the application has a moderate RTO and a moderate budget
   • BWhen the application requires immediate failover with zero data loss
   • CWhen the application can tolerate a long recovery time and has a low budget
   • DWhen the application is critical and cannot tolerate any downtime
