Domain 3.2: Design for high availability

You are designing the global routing architecture for a public-facing e-commerce web application. The application is hosted on Azure App Service in three regions: East US, West Europe, and Southeast Asia. Requirements: - Route users to the closest region to minimize latency. - Provide SSL/TLS termination at the edge. - Protect the application from common web vulnerabilities (SQL injection, XSS) using a Web Application Firewall (WAF). - Cache static content (images, CSS) at the edge. Which Azure service should you recommend?

You are deploying a cluster of 6 Azure Virtual Machines for a critical application. You need to ensure the highest possible availability within a single Azure region. The architecture must protect against datacenter-level failures (e.g., power, cooling, or network outages affecting an entire building). Which THREE statements regarding Availability Zones are correct? (Select THREE)

A company is designing a storage architecture for a new application. The application requires high availability for its data. If an entire Azure datacenter goes offline due to a fire, the application must continue to read and write data without any manual intervention or configuration changes. However, the company wants to avoid the costs associated with replicating data to a completely different geographic region. Which storage redundancy option should you recommend?

You are designing a global e-commerce web application hosted in three Azure regions (East US, West Europe, Southeast Asia). The application serves dynamic HTTP/HTTPS content. You need to design a load balancing solution that routes users to the closest region to minimize latency, provides SSL offloading, and includes a Web Application Firewall (WAF) to protect against SQL injection attacks. Which service should you recommend?

You are deploying a critical 3-tier application to Azure Virtual Machines in the East US region. You need to ensure the application remains available even if an entire Azure datacenter loses power or network connectivity. The solution must provide a 99.99% SLA for the virtual machines. How should you deploy the virtual machines?

You are designing a highly available architecture for an internal web application. The application is hosted on Azure Virtual Machines spread across three Availability Zones in the West Europe region. You need to deploy an Azure Application Gateway to load balance traffic to these VMs. The Application Gateway itself must survive a zone failure. Which TWO configurations are required for the Application Gateway? (Select TWO)
