A research organization runs a batch processing workload that requires high-performance computing (HPC) to simulate molecular dynamics. The workload is parallelizable and runs for several hours. The organization wants to use Azure for this workload and needs to minimize the time to complete the simulation. What should you recommend?

Use a single large VM with many vCPUs.

Use Azure Container Instances with GPU-enabled containers.

Use Azure Functions to run the simulation in parallel.

Use Azure Batch with a pool of HPC-optimized VMs.

A company runs a SQL Server database on a VM. The workload is predictable with steady CPU usage. The company wants to reduce costs by using Azure Hybrid Benefit and reserved capacity. What should you recommend?

Use a VM in the B-series with a reserved instance.

Use a Compute Optimized VM with Azure Hybrid Benefit and pay-as-you-go pricing.

Use a General Purpose VM with Azure Hybrid Benefit and a reserved instance.

Use a Burstable VM series and enable autoscale to handle peak loads.

A company processes incoming IoT telemetry messages. Each message triggers a short-lived function that enriches the data and writes it to Azure Cosmos DB. The workload is spiky and unpredictable. The team wants to pay only for actual executions and avoid managing servers. What should you recommend?

Use a Virtual Machine Scale Set running a custom listener that polls Event Hubs.

Use Azure Container Instances with a container that reads from Event Hubs.

Use an Azure Functions Consumption plan with an Event Hubs trigger.

Use Azure Kubernetes Service with a Kafka-based event-driven autoscaler.
