Question 2mediummultiple choice
Full question →A company is designing private access to a PaaS database from workloads in a VNet. The database should not be reachable over its public endpoint. What should be recommended?
Question 3hardmultiple choice
Full question →A data platform must support analytical queries over petabytes of files in a data lake, while preserving hierarchical namespaces and fine-grained ACLs. Which storage service should you design around?
Question 4mediummultiple choice
Full question →A database workload has an RPO of 15 minutes and an RTO of 4 hours. Cost is more important than near-zero data loss. Which design is usually more appropriate than synchronous multi-region replication?
Question 5hardmultiple choice
Full question →A multinational company uses Microsoft Entra ID and several Azure subscriptions. Security administrators need to review privileged role assignments every month and require justification for continued access. Which design should be recommended?
Question 6mediummultiple choice
Full question →A company is deploying a web application on Azure App Service. They need to guarantee that all traffic from the internet goes through a Web Application Firewall (WAF) before reaching the app. The solution must be cost-effective for a single application. Which Azure service should they place in front of the App Service?
Question 7easymultiple choice
Full question →A company has Azure virtual networks (VNets) in three different Azure regions (West US, East US, and West Europe). They also have an on-premises data center connected to the East US region via ExpressRoute. They need to connect all VNets to each other and to the on-premises network. The solution must support transitive routing between all sites and provide centralized management of connectivity and routing policies. Which Azure service should they use?
Question 8easymultiple choice
Full question →A company plans to deploy a web application on Azure VMs across multiple availability zones. They need to distribute incoming HTTP traffic across the VMs and provide health probes. Which Azure load balancing solution should they use?
Question 9hardmultiple choice
Full question →A company runs a large-scale write-intensive application that requires a horizontally scalable relational database. They need to distribute data across multiple nodes to handle high write throughput while supporting SQL queries, including joins and transactions. The solution must be fully managed and provide elastic scaling. Which Azure database service should they choose?
Question 10hardmultiple choice
Full question →A company runs an SAP HANA database on Azure large instances (HLI) in the West US region. The database is critical for business operations. They need a disaster recovery solution with a recovery point objective (RPO) of near zero (seconds) and a recovery time objective (RTO) of less than 30 minutes in the event of a region-wide outage. The solution must automatically replicate data to a secondary region (East US) and support automated failover. Which design should they implement?
Question 11easymultiple choice
Full question →A company has multiple branch offices and needs to connect them to Azure and to each other using a scalable, managed solution that simplifies network architecture. The solution should support automatic routing and integration with ExpressRoute and VPN. Which Azure service should they use?
Question 12hardmultiple choice
Full question →A business-critical App Service application must survive a full regional outage. The recovery design should fail over automatically based on endpoint health and avoid DNS-cache delay where possible. Which service should front the regional deployments?
Question 13mediummultiple choice
Full question →A company is building a customer-facing web application. They want to allow users to sign in using their existing social accounts (Microsoft, Google, Facebook) or create a local account. The solution must be fully managed and support custom branding. Which Azure service should they use?
Question 14easymultiple choice
Full question →A company deploys a web application across multiple Azure VMs in a single region. They want to distribute incoming HTTP traffic evenly across the VMs, offload SSL encryption, and provide a fixed public IP address for clients. Which Azure load balancing solution should they use?
Question 15mediummultiple choice
Full question →A company deploys a web application on multiple Azure VMs in a single region. They need to distribute incoming HTTP and HTTPS traffic across the VMs, offload SSL/TLS termination, and maintain session persistence (sticky sessions) so that all requests from a user session go to the same backend VM. Which Azure load balancing solution should they use?
Question 16easymultiple choice
Full question →A company deploys a web application on multiple Azure virtual machines (VMs) in a single region. The application receives HTTP and HTTPS traffic. They need to distribute the traffic across the VMs, offload SSL/TLS termination, and ensure that client requests from the same user session are always sent to the same backend VM (session persistence). Additionally, they need to route requests based on URL paths (e.g., /api/* to one pool, /images/* to another). Which Azure load balancing solution should they use?
Question 17easymultiple choice
Full question →A company deploys a web application on Azure VMs across availability zones. They need to distribute HTTPS traffic, offload SSL termination, and maintain session persistence. They do not require traffic inspection. Which Azure load balancing solution should they use?
Question 18hardmultiple choice
Full question →A company is designing a hub-spoke network topology in Azure. The hub contains a third-party network virtual appliance (NVA) for inspection. Spokes need to communicate with each other, and all inter-spoke traffic must be routed through the NVA in the hub. Which configuration should they use?
Question 19mediummultiple choice
Full question →A company manages a fleet of millions of IoT devices that send telemetry data every minute. The data must be stored for 10 years to meet compliance requirements. For the first 30 days, data is accessed frequently for real-time dashboards and alerting. After 30 days, data is only accessed occasionally for historical analysis and reporting. The solution must be cost-effective and support high ingestion rates. Which Azure service should the company use to store and query this data?
Question 20easymultiple choice
Full question →A company is designing a virtual network architecture for a three-tier application (web, application, database). They want network isolation between tiers and secure access from the internet to the web tier only. Which Azure networking solution should they use?
