A smart home device manufacturer hosts its IoT telemetry collection service on Microsoft Azure. The service must meet the following operational criteria:
1. Telemetry data from devices must be processed with consistent, predictable latency even during peak evening hours when device usage spikes.
2. In the event of a catastrophic disaster that completely disables the primary Azure region, the manufacturer must be able to restore the collection service in a secondary region.
Which two cloud computing concepts or benefits directly address these criteria? (Select two.)
- Performance predictability, to ensure consistent processing latency during peak usage hoursAnswer
- Disaster recovery, to restore the service in a secondary region after a regional outageAnswer
- CHigh availability, to ensure automated recovery and zero data loss across multiple regions
- DAvailability Zones, which replicate data across separate regions to prevent regional data loss
Answer
The correct concepts are performance predictability and disaster recovery.
Performance predictability and disaster recovery are the correct options. Performance predictability ensures consistent response times and processing speed under varying loads. Disaster recovery ensures that services and data can be restored in a secondary geographical location if the primary region becomes unavailable.
