   A company runs a critical application on virtual machines in a single availability zone. The application must be highly available and tolerate the failure of one VM without manual intervention. The company wants to keep costs reasonable. Which solution should the company implement?

   • AUse a single VM with a managed disk and enable geo-redundant storage for the disk.
   • BPlace multiple VM instances in an availability set or spread across multiple availability zones and use a load balancer with health probes.
   • CEnable automatic restart for the single VM instance.
   • DCreate a larger VM instance with more resources to reduce the chance of failure.

   A cloud security team has documented a BCDR plan that includes automated failover to a secondary region. Before the plan is approved, the team must validate that the RTO and RPO are achievable. Which testing method provides the most realistic validation without impacting production traffic?

   • AReview the RTO and RPO metrics in the plan documentation.
   • BRun a backup restoration test in a sandbox environment.
   • CPerform a full failover test during a maintenance window using cloned production data.
   • DConduct a tabletop exercise where team members discuss the plan step by step.

   An e-commerce company deploys a stateless web application across multiple virtual machines behind a load balancer. The application must remain available if an entire availability zone fails. The company also wants to minimize the need for manual intervention during such an event. Which architecture should the company implement?

   • ADeploy VM instances in at least two availability zones and configure an automated health-check-based failover in the load balancer.
   • BDeploy all VM instances in a single availability zone and enable automatic restart on failure.
   • CDeploy instances in two regions and use DNS-based failover with a manual switchover script.
   • DUse a single larger VM instance in one availability zone and rely on the cloud provider's infrastructure redundancy.

   A company has an automated failover system that uses a health check to detect primary region failure. The health check endpoint is hosted in the same region as the primary application. During a regional outage, the health check also fails, and the failover does not trigger. What is the best way to make the failover more reliable?

   • AUse a secondary health check endpoint in the same region but on a different VM.
   • BHost the health check endpoint in a separate region or use a third-party monitoring service.
   • CIncrease the timeout of the health check to avoid false positives.
   • DDisable the health check and rely on manual failover.

   A company operates in a jurisdiction that requires personal data to be stored and processed only within the country's borders. The company is designing a disaster recovery plan and wants to use a secondary region in a neighboring country for failover. Which of the following actions would allow the company to use the neighboring country region?

   • AEncrypt all data before replication and ensure the encryption keys are stored in the home country.
   • BUse a cloud provider that offers a region within the home country for disaster recovery.
   • CAnonymize the data before replicating it to the neighboring country.
   • DObtain explicit consent from all data subjects to store their data in the neighboring country.
