A global logistics firm is migrating its supply chain dashboard to Microsoft Azure. The system must meet strict requirements for both performance consistency during high-demand events and business continuity in the event of a severe outage.
Which of the following statements correctly describe how the company should implement reliability, predictability, or disaster recovery in Azure? (Select two)
- Implementing autoscaling to dynamically adjust virtual machine instances helps maintain consistent response times during peak demand, demonstrating performance predictability.Cevap
- BReplicating databases across multiple Availability Zones within the same Azure region is the primary strategy to achieve disaster recovery during a complete region-wide failure.
- Configuring virtual machine replication to a secondary, paired Azure region using Azure Site Recovery ensures business continuity, representing a disaster recovery strategy.Cevap
- DRelying on manual vertical scaling (scaling up) to dynamically adjust server sizes is the primary method used to achieve cloud elasticity for rapidly fluctuating, minute-by-minute traffic spikes.
Cevap
The correct statements are that implementing autoscaling to dynamically adjust virtual machine instances demonstrates performance predictability, and configuring virtual machine replication to a secondary paired region represents a disaster recovery strategy.
The correct design choices involve implementing autoscaling to maintain consistent performance (performance predictability) and replicating workloads to a secondary Azure region (disaster recovery). Autoscaling dynamically adjusts resource count to keep latency stable, ensuring predictable user experience. Replicating resources to a geographically distinct paired region ensures that if the primary region fails entirely, the services can be failed over and restored, which defines disaster recovery.
