A financial services firm is architecting a distributed transaction processing platform on Azure Virtual Machines. The platform requires high-speed inter-node communication with sub-millisecond latency. To meet compliance and business continuity mandates, the compute infrastructure must guarantee an uptime SLA of at least $99.99\%$ and withstand the failure of an entire datacenter facility within a region.

Which two actions should you include in the design? (Select two.)

A logistics company is designing a new cloud-native fleet tracking solution on Azure. The solution requires hosting two distinct workloads:

* A real-time telemetry service that processes GPS events from delivery vehicles. This service must scale out dynamically based on the number of pending messages in an Azure Service Bus queue using KEDA.
* A route optimization batch job that runs once per day, processes historical route data to completion, and then terminates.

The solution must minimize administrative effort.

Which of the following compute and storage deployment strategies should you recommend to meet these requirements?

You are designing the serverless compute architecture for a telemetry processing solution. The solution must support two workloads:

* Workload 1: An HTTPS ingestion endpoint that receives telemetry data in unpredictable spikes. The endpoint must scale to zero when idle, support outbound virtual network (VNet) integration to connect to a private backend database, and minimize cold-start latency.
* Workload 2: A batch processing job that runs whenever a new raw data file is uploaded to Azure Blob Storage. Each execution performs complex transformations and takes approximately $15$ minutes to complete.

Which two hosting plans should you recommend to meet the requirements for the workloads? (Select two.)

A retail logistics company is designing the compute infrastructure for a new real-time inventory routing engine. The system has the following requirements:
- Must run continuously 24/7 as a steady-state production workload with a guaranteed virtual machine uptime SLA of 99.99%.
- Requires memory-optimized compute resources offering at least 8 GB of RAM per vCPU.
- Requires high-performance storage capable of sustaining at least 50,000 IOPS.
- Must ensure that data is encrypted in memory during execution to comply with strict internal data security standards.

Which compute and storage architecture should you recommend to meet these requirements?

A healthcare provider ingests patient monitoring telemetry into an Azure Blob Storage account. The storage solution must remain resilient against a primary datacenter outage. The data lifecycle and access patterns are defined as follows:

* The telemetry is highly active and requires sub-second retrieval latency for the first $14$ days.
* From day $15$ through day $90$, the telemetry is accessed infrequently but must be available for immediate, sub-second querying.
* After $90$ days, the telemetry is only accessed for regulatory compliance audits that tolerate a retrieval latency of up to $15$ hours.
* All telemetry must be retained for $7$ years ($2,555$ days) and then deleted.

You need to design a storage and lifecycle management strategy that meets these requirements at the lowest possible cost.

A healthcare provider is deploying a regional medical records synchronization service on virtual machines in a single Azure region. The service requires low-latency TCP communication on port 5000, does not require SSL/TLS termination, and does not require URL-based routing. To distribute traffic, the provider attempts to configure an Azure Standard Load Balancer. However, the deployment fails because the backend virtual machines are associated with Basic SKU public IP addresses.

Which action should you recommend to resolve the deployment failure while meeting all service requirements?

An enterprise is designing a disaster recovery and business continuity solution for a web application deployed across the East US and West US regions. The application consists of an HTTPS-based frontend and an Azure SQL Database backend.

- Offload SSL/TLS decryption from the backend web servers to a centralized global entry point.
- Provide automatic failover for the database layer with a single connection string that automatically redirects write operations to the new primary server.
- Ensure that the primary web application can survive a regional outage with minimal manual intervention.
