Cevap: Deploy two Azure Dedicated Hosts of the Esv5-family (one in Availability Zone 1 and one in Availability Zone 2). Deploy one E32s v5 virtual machine on each host, and configure the database log volume using Premium SSD v2 disks.

Cevap

Deploy two Azure Dedicated Hosts of the Esv5-family (one in Availability Zone 1 and one in Availability Zone 2), deploy one E32s v5 virtual machine on each host, and configure the database log volume using Premium SSD v2 disks.
Deploying two Azure Dedicated Hosts of the Esv5-family across two Availability Zones, running E32s v5 virtual machines with Premium SSD v2 disks, is correct. Esv5-series hosts and VMs provide the exact 1:8 CPU-to-memory ratio needed (32 vCPUs and 256 GiB RAM), avoiding the higher costs of overprovisioning. Azure Dedicated Hosts satisfy the physical isolation requirement at the host level. Placing the hosts and VMs in two different Availability Zones ensures the 99.95% VM availability SLA is met. Finally, Premium SSD v2 provides the required 20,000 IOPS and sub-millisecond latency for database logs cost-effectively.

Adım Adım Çözüm

1
Analyze compliance and hardware isolation requirements.
Azure Dedicated Hosts are required because the workload requires physical isolation at the hardware host level.
Dedicated Hosts provide physical servers dedicated to a single Azure subscription, satisfying physical isolation compliance.
2
Determine the optimal VM series based on the CPU-to-memory ratio.
Select the Esv5-series (specifically E32s v5) which offers a 1:8 vCPU-to-GiB RAM ratio (32 vCPUs and 256 GiB RAM).
General-purpose Dsv5-series (1:4 ratio) would require overprovisioning to 64 vCPUs to get 256 GiB RAM, which increases licensing and compute costs.
3
Design the architecture to meet the 99.95% availability SLA.
Provision two Dedicated Hosts distributed across two Availability Zones (Zone 1 and Zone 2) and deploy one VM on each host.
To achieve the 99.95% (or 99.99%) VM availability SLA, VM instances must be distributed across different fault domains or Availability Zones.
4
Select the storage disk type for the database log drive.
Configure the log drive with Premium SSD v2.
Premium SSD v2 supports sub-millisecond latency and can be provisioned with up to 80,000 IOPS, meeting the 20,000 IOPS database log requirements cost-effectively.

Cevap: Deploy the nightly batch processing job on Azure Spot Virtual Machines.; Deploy the customer-facing API on standard Azure Virtual Machines distributed across multiple Availability Zones.

Cevap

Deploy the nightly batch processing job on Azure Spot Virtual Machines, and deploy the customer-facing API on standard Azure Virtual Machines distributed across multiple Availability Zones.
Deploying the batch processing job on Spot Virtual Machines leverages idle Azure capacity at deep discounts, which is ideal because the workload can tolerate interruptions. Deploying the customer-facing API on standard Virtual Machines across multiple Availability Zones ensures that the production workload meets its 99.9% uptime SLA and remains highly available.

Adım Adım Çözüm

1
Analyze the requirements for the nightly batch processing workload.
The workload is non-critical, can tolerate interruptions, and must be highly cost-optimized. This makes it a perfect fit for Azure Spot VMs.
Spot VMs offer up to 90% cost savings compared to pay-as-you-go rates in exchange for the risk of eviction.
2
Analyze the requirements for the customer-facing API.
The API is critical, must run continuously, and requires a 99.9% SLA, which rules out Spot VMs.
Production workloads with strict SLAs require standard VMs with guaranteed runtimes.
3
Identify the high availability solution for the API VM deployment.
Deploying the standard VMs across multiple Availability Zones ensures protection against datacenter failures and meets the high availability SLA.
A single Availability Zone deployment does not protect against localized zone failures.

Cevap: Azure Reserved Virtual Machine Instances to reduce compute costs for the predictable workload.; Azure Virtual Machines deployed across multiple Availability Zones to meet the 99.99% availability SLA.

Cevap

Select Azure Reserved Virtual Machine Instances to reduce compute costs for the predictable workload, and deploy Azure Virtual Machines across multiple Availability Zones to meet the 99.99% availability SLA.
Azure Reserved Virtual Machine Instances are ideal for steady-state workloads running continuously, as they offer significant discounts for a committed term. To achieve the 99.99% availability SLA, Azure requires virtual machines to be deployed across multiple Availability Zones in a region.

Adım Adım Çözüm

1
Analyze the availability requirement.
The application requires a 99.99% availability SLA.
Azure guarantees a 99.99% uptime SLA for virtual machines only when two or more instances are deployed across two or more Availability Zones in the same region.
2
Analyze the cost optimization requirement for a 24/7 steady-state workload.
Azure Reserved Virtual Machine Instances (RIs) should be used.
Reserved Instances allow you to commit to a one-year or three-year plan, providing deep discounts for predictable, continuous compute workloads.
3
Evaluate and rule out incorrect options based on constraints.
Spot VMs and single zone deployments are ruled out.
Spot VMs can be evicted at any time and offer no SLA, making them unsuitable for production workloads. A single zone deployment cannot provide the 99.99% availability SLA.

A financial services company is designing a new payment processing application on Azure. The architecture consists of a transaction processing API tier and a stateful database tier. The application design must satisfy the following requirements:

* The database tier requires at least 256 GB of memory and high temporary storage throughput. To minimize SQL Server core-based licensing costs, the operating system must only see 8 vCPUs, while the database continues to utilize the memory and I/O performance of a 32-core virtual machine size.
* The transaction processing API tier handles highly sensitive financial data in transit. It must run in a secure, hardware-isolated execution environment that protects data in memory from external access, including the host operating system, hypervisor, and cloud administrators.
* The database tier must remain highly available and survive a primary datacenter outage without unexpected interruptions or evictions.

Cevap: Deploy the database tier on E32-8ds_v5 constrained vCPU virtual machines; Deploy the transaction processing API tier on DC-series or EC-series confidential virtual machines

Cevap

Deploy the database tier on E32-8ds_v5 constrained vCPU virtual machines and deploy the transaction processing API tier on DC-series or EC-series confidential virtual machines.
Deploying the database tier on E32-8ds_v5 constrained vCPU virtual machines provides the required 256 GB of memory and storage throughput of the E32ds_v5 size while limiting active vCPUs to 8, which minimizes SQL Server licensing costs. Deploying the transaction processing API tier on DC-series or EC-series confidential virtual machines meets the security requirement by encrypting memory in use at the hardware level using AMD SEV-SNP or Intel SGX, preventing access from the hypervisor and cloud operators.

Adım Adım Çözüm

1
Analyze the database core licensing constraint.
Determine that a constrained vCPU virtual machine size is required to provide high memory (256 GB) and high I/O throughput while limiting the OS-visible vCPUs to 8 to minimize licensing costs.
Azure offers constrained vCPU VM sizes (such as E32-8ds_v5) specifically for database workloads where memory and storage performance are needed but licensing costs are bound to core counts.
2
Analyze the secure execution environment requirement for the API tier.
Determine that confidential virtual machines (such as DC-series or EC-series) are required to protect data in memory from external access, including the hypervisor and administrators.
Confidential computing uses hardware-based Trusted Execution Environments (TEEs) to encrypt memory in use.
3
Evaluate the database tier availability requirements.
Rule out Azure Spot VMs due to eviction risks, and rule out single-zone deployments due to lack of resilience against datacenter outages.
Production database workloads must run on standard VM tiers across multiple availability zones to satisfy high availability SLAs.

Cevap: Deploy Workload 1 on Azure Dedicated Hosts allocated across multiple availability zones.; Deploy Workload 2 on Azure Spot Virtual Machines.

Cevap

Deploy Workload 1 on Azure Dedicated Hosts allocated across multiple availability zones, and deploy Workload 2 on Azure Spot Virtual Machines.
Deploying the core transaction processing system on Azure Dedicated Hosts across multiple availability zones satisfies both the physical hardware isolation requirement and the zone-level high availability requirement. Deploying the batch risk-modeling application on Azure Spot Virtual Machines leverages the cost-savings of unused Azure capacity for workloads that are highly tolerant of interruptions.

Adım Adım Çözüm

1
Analyze the requirements for Workload 1.
Workload 1 requires 24/7 steady-state operation, zone-level high availability, and physical isolation at the hardware level.
This establishes that multi-tenant Azure virtual machines (even with Reserved Instances) and Spot VMs are ruled out, requiring dedicated physical hardware (Azure Dedicated Hosts) configured across multiple availability zones.
2
Analyze the requirements for Workload 2.
Workload 2 runs on weekends, is highly parallelizable, can handle interruptions, and must be highly cost-effective.
This aligns perfectly with Azure Spot VMs, which utilize excess Azure capacity at a significant discount with the trade-off of potential eviction.
3
Evaluate the proposed options against the findings.
The strategy of deploying Workload 1 on Dedicated Hosts across zones and Workload 2 on Spot VMs satisfies all constraints.
This completes the selection of the correct two options while discarding options that violate high availability, physical isolation, or workload stability constraints.

Cevap: Azure Reserved Virtual Machines using Esv5-series VMs distributed across multiple Availability Zones for the telemetry ingestion engine; Azure Spot Virtual Machines using Fsv2-series VMs for the route-optimization analysis job

Cevap

The correct configurations are to use Azure Reserved Virtual Machines using Esv5-series VMs distributed across multiple Availability Zones for the telemetry ingestion engine, and Azure Spot Virtual Machines using Fsv2-series VMs for the route-optimization analysis job.
The correct configurations combine Azure Reserved Virtual Machines using Esv5-series VMs distributed across multiple Availability Zones for the telemetry ingestion engine with Azure Spot Virtual Machines using Fsv2-series VMs for the route-optimization analysis job. The telemetry engine is a continuous, steady-state workload requiring a memory-optimized series and a high SLA (99.99%99.99\%), which is achieved by deploying across multiple Availability Zones. Reserved instances reduce cost for this continuous running resource. The route-optimization job runs for a short duration and can tolerate interruptions, making Spot VMs the most cost-effective option.

Adım Adım Çözüm

1
Analyze the requirements for the telemetry ingestion engine.
The engine is a steady-state workload requiring continuous performance, a memory-optimized profile, and high availability (99.99%99.99\% SLA).
This establishes that we need a memory-optimized VM series (like Esv5-series) deployed in a zone-redundant configuration with a purchasing model suitable for continuous operations (like Reserved Instances to minimize cost).
2
Analyze the requirements for the route-optimization analysis job.
The job runs for 44 hours daily, is compute-intensive, can tolerate interruptions, and needs the lowest cost.
This indicates that Spot VMs (which provide deep discounts for interruptible workloads) paired with a compute-optimized VM series (like Fsv2-series) are the best fit.
3
Evaluate the distractors against these requirements.
Using Spot VMs for the telemetry engine risks eviction and violates the SLA. Deploying the telemetry engine in a single Availability Zone lacks redundancy. Azure Functions Consumption plan times out after 1010 minutes, failing the 4-hour runtime requirement.
This confirms that only the selected options meet all performance, SLA, and duration constraints.

Cevap: Azure Dedicated Hosts deploying Esv5-series virtual machines distributed across multiple Availability Zones, using Premium SSD v2 storage.

Cevap

Azure Dedicated Hosts deploying Esv5-series virtual machines distributed across multiple Availability Zones, using Premium SSD v2 storage.
The correct option satisfies all constraints: Azure Dedicated Hosts provide the required physical hardware isolation; the Esv5-series VM size provides the minimum 88 GiB of RAM per vCPU; Premium SSD v2 supports 10,00010,000 IOPS and allows independent performance scaling without disk resizing; and distributing VMs across multiple Availability Zones meets the 99.99%99.99\% availability SLA requirement.

Adım Adım Çözüm

1
Analyze the tenant isolation and workload characteristics.
Single-tenant physical host isolation requires Azure Dedicated Hosts, which rules out public multi-tenant virtual machines and Spot VMs.
Regulatory compliance demands dedicated hardware, and the steady-state nature rules out Spot VMs due to eviction risk.
2
Determine the memory and virtual machine series requirements.
A memory-to-vCPU ratio of 88 GiB requires a memory-optimized VM family like the Esv5-series, which is supported on Azure Dedicated Hosts.
General-purpose (D-series) or compute-optimized (F-series) families do not meet the minimum 88 GiB per vCPU requirement.
3
Evaluate storage performance and scaling capabilities.
Premium SSD v2 is selected because it supports provisioning up to 80,00080,000 IOPS and allows independent tuning of IOPS and throughput without resizing the disk.
Standard SSDs do not scale to 10,00010,000 IOPS, and Standard/Premium SSD v1 requires expanding disk size to increase performance limits.
4
Validate the SLA and high availability design.
Distribute the Azure Dedicated Hosts and corresponding virtual machines across at least two Availability Zones.
A 99.99%99.99\% SLA for Azure VMs requires instances to be deployed across two or more Availability Zones in the same region.

Cevap: A Virtual Machine Scale Set utilizing DCasv5-series Virtual Machines deployed across three Availability Zones, with Premium SSD v2 disks for database transaction logs.

Cevap

A Virtual Machine Scale Set utilizing DCasv5-series Virtual Machines deployed across three Availability Zones, with Premium SSD v2 disks for database transaction logs.
The correct option combines a Virtual Machine Scale Set (VMSS) with confidential computing (DCasv5-series) for hardware-based memory encryption. Distributing these VMs across three Availability Zones ensures a 99.99% SLA. Utilizing Premium SSD v2 satisfies the sub-millisecond write latency and high IOPS required for database transaction logs.

Adım Adım Çözüm

1
Analyze security requirements for memory encryption.
Identify that confidential computing (DC-series, such as DCasv5) is required to provide hardware-based virtualization and memory encryption for sensitive data in use.
Standard virtual machines do not encrypt data in memory during processing.
2
Analyze availability requirements for SLA.
Select a multi-zone deployment strategy across at least two (ideally three) Availability Zones to qualify for the 99.99% Virtual Machine SLA.
Single Availability Zone deployments only guarantee up to a 99.9% SLA.
3
Determine compute orchestration and scaling requirements.
Select Virtual Machine Scale Sets (VMSS) to support automatic scaling rules.
Individual virtual machines require manual scaling configuration and do not group instances uniformly out-of-the-box.
4
Select storage tier for database transaction logs.
Choose Premium SSD v2 to achieve sub-millisecond write latency and support high IOPS.
Standard HDD disks are slow, high-latency, and unsuitable for database write-intensive workloads.

Cevap: Azure Spot Virtual Machines for Workload 1; Azure Dedicated Hosts for Workload 2

Cevap

Azure Spot Virtual Machines for Workload 1 and Azure Dedicated Hosts for Workload 2
Azure Spot Virtual Machines are correct for the video rendering workload because they allow the customer to take advantage of unused Azure capacity at significant cost savings, which is ideal for workloads that are non-urgent and can be interrupted. Azure Dedicated Hosts are correct for the licensing service because they provide physical servers dedicated to a single Azure subscription, satisfying the physical isolation requirement, and support zone-redundant deployments to meet the 99.99% SLA.

Adım Adım Çözüm

1
Analyze the requirements for Workload 1.
Identify that the workload consists of background, non-urgent, interruptible tasks where minimizing cost is the primary goal.
This establishes that the workload is suitable for transient compute models.
2
Evaluate compute solutions for Workload 1.
Determine that Azure Spot Virtual Machines offer the lowest cost for workloads that can tolerate eviction.
This matches the low-cost and interruptible nature of the video rendering jobs.
3
Analyze the requirements for Workload 2.
Identify that the workload requires physical hardware isolation for regulatory compliance and a 99.99% availability SLA.
This dictates the need for non-shared physical infrastructure and high-availability design.
4
Evaluate compute solutions for Workload 2.
Determine that Azure Dedicated Hosts provide physical isolation at the host level and can be placed across multiple availability zones to meet the 99.99% SLA.
This fully addresses the compliance and availability constraints.

Cevap: Deploy Azure Dedicated Hosts for Ev5-series virtual machines across at least two Availability Zones, and provision standard virtual machines on these hosts.

Cevap

Deploy Azure Dedicated Hosts for Ev5-series virtual machines across at least two Availability Zones, and provision standard virtual machines on these hosts.
Deploying Azure Dedicated Hosts provides physical servers dedicated to a single Azure subscription, satisfying the hardware isolation requirement. To achieve a 99.99%99.99\% availability SLA, Dedicated Hosts must be deployed across at least two Availability Zones in a region. Standard virtual machines (such as the memory-optimized Ev5-series) running on these hosts ensure steady-state, continuous execution without the eviction risk associated with Spot instances.

Adım Adım Çözüm

1
Identify the hardware isolation requirement.
Requires the use of Azure Dedicated Hosts to ensure the physical servers are dedicated to a single Azure subscription.
Standard multi-tenant virtual machines do not satisfy the hardware isolation compliance rule.
2
Determine the availability SLA requirement.
Requires deploying the Dedicated Hosts across at least two Availability Zones in the selected Azure region.
An availability SLA of 99.99%99.99\% for virtual machines requires multi-zone deployment. A single zone deployment only provides a lower SLA.
3
Evaluate the workload continuity and eviction constraints.
Requires provisioning standard (non-Spot) virtual machines.
Azure Spot VMs are subject to eviction at any time when capacity is needed, which violates the requirement to run continuously without unexpected evictions or interruptions.
4
Match the compute memory requirement.
Configure Ev5-series virtual machines on the Dedicated Hosts.
Ev5-series virtual machines are memory-optimized and satisfy the high memory-to-vCPU ratio constraint.

Cevap: Deploy ECesv5-series confidential virtual machines across two or more Availability Zones with Premium SSD v2 storage.

Cevap

Deploy ECesv5-series confidential virtual machines across two or more Availability Zones with Premium SSD v2 storage.
The correct architecture uses ECesv5-series VMs which utilize AMD SEV-SNP technology to encrypt data in use, satisfying the security requirement, and provide 8 GB RAM per vCPU, satisfying the memory-optimized requirement. Distributing these VMs across multiple Availability Zones guarantees a 99.99% uptime SLA. Attaching Premium SSD v2 disks easily meets the 50,000 IOPS threshold.

Adım Adım Çözüm

1
Analyze security and memory requirements.
Identify that the system requires confidential computing (in-memory encryption) and memory-optimized resources (8 GB RAM per vCPU). The ECesv5-series meets both criteria.
This filters out general-purpose options like DCesv5-series and standard non-confidential options.
2
Analyze SLA and availability requirements.
To meet the 99.99% virtual machine uptime SLA, the virtual machines must be deployed across two or more Availability Zones in the same region. Deploying in a single zone or using Spot VMs is ruled out.
Single zone deployments offer up to 99.9% SLA, and Spot VMs offer no SLA due to eviction risk.
3
Analyze storage performance requirements.
Verify that Premium SSD v2 can sustain the required 50,000 IOPS.
Standard SSDs cannot scale to 50,000 IOPS, which eliminates options using lower-tier storage.
