A company runs a high-performance computing (HPC) workload that requires InfiniBand interconnect for tightly coupled MPI jobs. The workload also has a less critical, loosely coupled component that can run on regular Ethernet. The team wants to minimize cost while meeting the performance requirements. What should you recommend?

Use Azure Batch with a single pool of InfiniBand-enabled VMs for both components.

Use a single VM size that supports InfiniBand for both components.

Use a VM size with high CPU but no InfiniBand for the MPI jobs.

Use two VM sizes: one with InfiniBand for the MPI jobs and a cheaper size for the loosely coupled component.

A company runs a stateful legacy application that requires a fixed IP address and low latency to an on-premises database. The application is not containerized and must run on a dedicated VM. What should you recommend?

Use a VM in a VNet with a private IP and connect to the database via ExpressRoute.

Use Azure Functions with a virtual network integration and connect to the database.

Use Azure Container Instances with a static IP and connect to the database via VPN.

Use a VM with a static public IP and connect to the database over the internet.

A workload consists of multiple independent microservices that need to communicate asynchronously via messages. The solution should scale each microservice independently and minimize infrastructure management. Which Azure serverless computing approach should the architect recommend?

Azure Virtual Machines with a message queue

Azure Functions with Azure Service Bus

Azure Container Instances with a message queue

A solution architect is designing a container-based solution that requires automatic scaling, service discovery, and rolling updates for a microservices application. Which Azure service should the architect recommend?

Azure Container Instances (ACI)

A workload requires running a containerized application that must scale automatically based on HTTP traffic, but the organization wants to avoid managing the underlying Kubernetes infrastructure. Which Azure service should the architect recommend?

Azure App Service for Containers

Azure Container Instances (ACI)
