A company runs a global web application that serves users in North America and Europe. The application is deployed in two cloud regions. The company wants to route users to the region with the lowest latency and automatically fail over to the other region if one region becomes unavailable. Which service should they use?

Use a DNS service with a round-robin record that lists both regions.

Use a global load balancer with latency-based routing and health checks.

Use a regional load balancer in each region and configure users to manually select their region.

Use a content delivery network (CDN) to cache static content and route all traffic to a single region.

A company runs a global e-commerce application with a database that must be available in two regions. The application requires that a user always sees the same data after a write, even if they are immediately routed to the other region. The company is willing to accept higher write latency to achieve this. Which data replication strategy should they use?

Use synchronous replication between the two regions, ensuring that a write is acknowledged only after it is committed in both regions.

Use a single primary database in one region and a read replica in the other region with asynchronous replication.

Use a multi-leader replication strategy with asynchronous replication and a global load balancer that routes users to the region with the most recent data.

Use asynchronous replication with a conflict resolution mechanism, allowing writes to be applied to the local region first.
