Google Cloud Digital LeaderGeneral knowledge of Google CloudMedium
A multinational corporation needs to deploy applications globally with low latency for users in different continents. They also require robust disaster recovery capabilities, ensuring business continuity even if an entire region experiences an outage. Which aspect of Google Cloud's global infrastructure is most relevant to meet these requirements?
- AMultiple regions with interconnected zones
- BEdge locations for CDN caching
- CVirtual Private Cloud (VPC) networks
- DDedicated interconnects to on-premises data centers
Show answer & explanationAnswer & explanation
Correct answer: A. Multiple regions with interconnected zones
Google Cloud's global infrastructure consists of multiple regions, each containing multiple zones. Deploying applications across multiple regions provides low latency to users worldwide and enables robust disaster recovery by allowing failover if an entire region becomes unavailable.
Why the other options are wrong
- B. Edge locations reduce latency for static content but don't address disaster recovery for applications.
- C. VPC networks define private network topology within a project but don't inherently provide global deployment or disaster recovery across regions.
- D. Dedicated interconnects link on-premises to Google Cloud, not between Google Cloud regions for global deployment or disaster recovery.
Google Cloud Regions and Zones
Google Cloud infrastructure is organized into regions (geographic areas) and zones (isolated locations within a region), providing high availability and disaster recovery.
- Regions are independent geographic areas.
- Zones are isolated failure domains within a region.
- Deploying across multiple regions provides global reach and disaster recovery.
