Your production application is hosted in Google Compute Engine in the us-central1-a zone and must be available 24/7. After an outage due to a zone failure and performance issues during peak usage, you're tasked with recommending a cost-effective, scalable solution resilient to zone failures. What's your recommendation?
Your production application is hosted in Google Compute Engine in the us-central1-a zone and must be available 24/7. After an outage due to a zone failure and performance issues during peak usage, you're tasked with recommending a cost-effective, scalable solution resilient to zone failures. What's your recommendation?
Explanation:
The correct answer is A. Distributing resources across multiple zones with Managed Instance Groups (MIGs) and enabling Autoscaling ensures resilience against zone failures and scalability during peak loads. Preemptible instances (option B) are cost-effective but unsuitable for 24/7 applications due to their temporary nature. Single-zone MIGs (option C) lack zone failure resilience. Unmanaged Instance Groups (option D) do not support Autoscaling, making them less ideal for scalable solutions. References: Preemptible VMs, Unmanaged Instance Groups, Regions and Zones, Autoscaler.
