   Which statement best describes the architecture of availability zones?

   • AZones are geographically distant regions, each with its own cloud provider
   • BZones are virtual networks that can span multiple data centers
   • CZones are logical partitions within a single data center, sharing all physical resources
   • DEach zone is an independent data center with its own power, cooling, and networking, and zones are connected by low-latency links

   What is the primary purpose of application availability zones in a cloud environment?

   • ATo provide isolated locations within a region that can host application components to improve fault tolerance
   • BTo create a single, highly secure network segment for all application traffic
   • CTo enable automatic scaling of application resources based on demand
   • DTo provide a backup copy of the entire application in a different geographic region

   What is the benefit of deploying an application across multiple availability zones?

   • AThe application will have lower latency for all users
   • BThe application will be protected from all types of failures, including data corruption
   • CThe application will automatically scale to handle more traffic
   • DThe application can continue to operate if an entire zone becomes unavailable

   A company deploys a stateless web application to three availability zones in a single region. A load balancer distributes traffic across all three zones. One zone experiences a complete failure. What is the expected behavior of the application?

   • AThe load balancer automatically provisions new resources in a different region
   • BThe application remains available, but all sessions are lost because the failed zone held the session state
   • CThe load balancer continues to route traffic to the remaining two zones, and the application remains available
   • DThe application becomes unavailable because all three zones must be healthy

   A company deploys a web application across three availability zones. They use a public load balancer to distribute traffic. The load balancer is configured with health probes. What is the role of the health probes in this architecture?

   • ATo detect unhealthy VMs or zones and stop routing traffic to them
   • BTo replicate data between the VMs in different zones
   • CTo encrypt traffic between the load balancer and the VMs
   • DTo scale the number of VMs in each zone based on traffic
