- A payments platform must process each account's transactions strictly in arrival order, prevent a publisher's retries from creating duplicate charges, and sustain several million messages a day with predictable throughput. Which messaging service fits?Medium
- A governance team wants a workflow that starts whenever a resource is created or deleted anywhere in a subscription, and also fans out one custom business event to three separate handler services, each retried on failure. Which combination of services should you use?Easy
- A payments team's application servers sit in a spoke network and must reach an Azure SQL logical server while keeping every packet on private addressing and off Microsoft's public endpoints. Which feature gives the database an address inside the team's own subnet?Medium
- A logistics platform has order-service microservices that publish status updates. Updates for the same order must be processed strictly in the sequence they were sent, and no update may be lost if a consumer crashes mid-processing. Which Azure messaging capability should you choose?Medium
- A regulated bank wants every packet that leaves a workload subnet for the internet to pass through a central inspection point that logs flows and applies threat rules. Which configuration achieves this?Medium
- Two manufacturing plants each have a private ExpressRoute circuit to Microsoft. They want their plant networks to exchange data directly across Microsoft's private backbone, with no internet path and no extra VPN appliances. Which feature enables this?Hard
- A public API handles bursts of short requests that go quiet for hours at a time. The team wants new instances to appear within seconds during a spike, capacity to drop to zero when idle, and billing only for the executions and resources actually used. Which compute option is the most cost-effective?Easy
- A software vendor hosts one internal service inside its virtual network and must let a handful of customer networks reach that service over private addresses. Customers must not see the rest of the vendor's network, and the service must stay off the public internet. Which approach fits these constraints?Hard
