AZ-305 Question #231: Real Exam Question with Answer & Explanation

Question

A company has container-based workloads and asks you to advise how to protect the multi- region AKS deployments from regional outages. What two services would you recommend for the company to implement?

Options

• AAzure Backup
• BAzure VM Scale sets
• CAzure Traffic Manager
• DAzure App Service
• EAzure Load Balancer

Explanation

Azure provides several disaster recovery tools for container-based workloads. To protect the multi-region Azure Kubernetes Service deployments from the regional outages, you need to implement Azure Traffic Manager. Azure Traffic Manager is a global load balancing service based It provides high availability and disaster recovery for container-based workloads. If one region fails, Azure Traffic Manager will direct the traffic to the secondary region. Traffic Manager routes any protocol (not only HTTP/HTTPS as Azure Front Door or Azure Application Gateway does) to the service endpoint's public IP address based on the routing method. Using geographic routing, it will direct the traffic to the closest AKS cluster and application instance. Then, the Load Balancer will take care of data delivery to the AKS. Option A is incorrect because you need to use the Traffic Manager and Load Balancer services for multi-region AKS protection from the regional outages, but not the Azure Backup service. However, the Azure Backup service protects the application data. Your container-hosted application uses Azure Storage disks or file shares, and Azure Backup will be an appropriate data recovery service. Option B is incorrect because you need to use the Traffic Manager and Load Balancer services for multi-region AKS protection from the regional outages, but not the Azure VM Scale sets. However, in case of node failures, Azure Kubernetes Service uses VM Scale sets to protect the Option D is incorrect because you need to use the Traffic Manager service and Load Balancer services for multi-region AKS protection from the regional outages, but not the Azure App Service. Azure App Service is a fully managed web application hosting platform. https://docs.microsoft.com/en-us/azure/aks/operator-best-practices-multi-region#use-azure- traffic-manager-to-route-traffic https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-configure-geographic- https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-configure-geographic-
