A shipping and logistics company is planning to migrate its fleet dispatch portal to Microsoft Azure. The cloud architecture team must meet the following requirements:
1. If a primary Azure region experiences a catastrophic outage, the portal must be restored in a secondary region within two hours.
2. The portal must maintain a consistent user experience with stable latency, even during sudden workload spikes.
Which of the following concepts directly address these requirements? (Select TWO)
- Disaster recovery, which focuses on recovering from a catastrophic outage and restoring operations in a secondary region to meet the Recovery Time Objective (RTO).Answer
- Performance predictability, which ensures that resources scale dynamically to maintain consistent application response times during sudden traffic spikes.Answer
- CHigh availability, which is the primary cloud concept dedicated to replicating virtual machines across different regions to recover from regional natural disasters.
- DPredictability, which is configured by pinning resources to a single Availability Zone to ensure they automatically failover across geographic boundaries.
Answer
Disaster recovery (which restores operations in a secondary region after a catastrophic outage) and performance predictability (which maintains consistent latency and resource availability during traffic spikes) are the correct selections.
The requirement to recover the portal in a secondary region within two hours is addressed by disaster recovery, which relies on metrics like Recovery Time Objective (RTO). The requirement to maintain consistent performance and latency during traffic spikes is addressed by performance predictability.
