Question 370
A legacy finance application requires a full Windows Server guest with installed proprietary software. Which implementation step would best fulfill the stated requirement?
- Configure the VPN gateway, local network gateway and tunnel settings.
- Deploy the runtime on an eligible chosen compute platform.
- Connect the function to a compatible trigger with appropriate rights.
- Provision a compatible Windows VM with needed disk and network settings.
Explanation
Correct Answer
D:Provision a compatible Windows VM with needed disk and network settings. The implementation operationalizes this design choice: Choose Azure Virtual Machines for guest OS and application control. Acceptance should demonstrate: The proprietary software installs and runs under the customer's guest administration.
Incorrect Answers
A:This setup is relevant to another workload: A company needs encrypted site-to-site connectivity from its existing office to an Azure VNet. The current configuration must instead achieve: The proprietary software installs and runs under the customer's guest administration.
B:That action implements a different requirement: A developer wants to host a Linux application with a custom runtime not supported by a managed web tier. It does not establish the required result in this case: The proprietary software installs and runs under the customer's guest administration.
C:This change would be appropriate under a different condition: A data collector runs short tasks when messages arrive, and demand varies sharply. Here it would not validate: The proprietary software installs and runs under the customer's guest administration.
Question 371
A legacy finance application requires a full Windows Server guest with installed proprietary software. Which result would best demonstrate successful implementation?
- VNet clients resolve internal hostnames to private addresses.
- Authorized users open their virtual desktop sessions remotely.
- The VMs communicate over their approved private network.
- The proprietary software installs and runs under the customer's guest administration.
Explanation
Correct Answer
D:The proprietary software installs and runs under the customer's guest administration. That directly tests the stated requirement: A legacy finance application requires a full Windows Server guest with installed proprietary software. It contrasts with the observed failure: The application host does not permit required guest OS changes.
Incorrect Answers
A:This observation is evidence for a separate scenario: A private VNet workload needs internal name resolution not exposed to public DNS. It does not test the necessary outcome here: The proprietary software installs and runs under the customer's guest administration.
B:That check tests another control: A company wants hosted Windows desktops accessed by employees from different locations. The decisive result for this workload is: The proprietary software installs and runs under the customer's guest administration.
C:The test is relevant when a security team needs to place two front-end VMs on the same isolated Azure network. It cannot establish the specified acceptance result: The proprietary software installs and runs under the customer's guest administration.
Question 372
A legacy finance application requires a full Windows Server guest with installed proprietary software. The team observes: The application host does not permit required guest OS changes. What should the team identify as the primary mechanism behind the problem?
- The application lacked a consistent containerized dependency package.
- A managed app service was chosen despite the need for VM-level control.
- The network filtering rules were missing or excessively permissive.
- No event/schedule-triggered managed execution was configured.
Explanation
Correct Answer
B:A managed app service was chosen despite the need for VM-level control. That explains the symptom: The application host does not permit required guest OS changes. The targeted corrective action is: Provision a compatible Windows VM with needed disk and network settings.
Incorrect Answers
A:This cause is consistent with a different issue: A program works on one machine but fails because libraries differ. It does not account for the reported symptom here: The application host does not permit required guest OS changes.
C:That explanation belongs to a different fault pattern: A VM has a public IP and every management port accepts traffic. It does not explain why the application host does not permit required guest OS changes.
D:This cause is consistent with a different issue: The program runs only if an operator manually logs into a server. It does not account for the reported symptom here: The application host does not permit required guest OS changes.
Question 373
A retail API must automatically add identical VM workers during holiday traffic. Which design choice best fits the stated business constraint?
- Use an Azure Virtual Network as the logical private networking boundary.
- Use subnets and appropriate network controls within the VNet.
- Evaluate an Azure availability set where it meets the workload's resilience needs.
- Use Azure Virtual Machine Scale Sets for repeatable VM instance scaling.
Explanation
Correct Answer
D:Use Azure Virtual Machine Scale Sets for repeatable VM instance scaling. The governing requirement is: A retail API must automatically add identical VM workers during holiday traffic. This solution specifically supports the outcome that worker count rises when qualifying demand increases.
Incorrect Answers
A:This design is appropriate for a different requirement: A security team needs to place two front-end VMs on the same isolated Azure network. Here the decisive outcome must instead be: Worker count rises when qualifying demand increases.
B:That concept addresses this separate situation: A three-tier app must isolate database traffic from front-end workload traffic. It does not by itself establish the result required here: Worker count rises when qualifying demand increases.
C:This option solves a different planning problem: Two critical VMs in one region need separation from common host hardware maintenance faults. The current acceptance criterion is specific: Worker count rises when qualifying demand increases.
Question 374
A retail API must automatically add identical VM workers during holiday traffic. Which Azure setup action best follows from this scenario?
- Choose the appropriate VM SKU and compatible driver stack.
- Deploy a scale set with autoscale and a suitable image configuration.
- Create an AKS cluster and configure supported node and network settings.
- Provide a supported subnet, NIC and managed OS disk to the VM.
Explanation
Correct Answer
B:Deploy a scale set with autoscale and a suitable image configuration. The implementation operationalizes this design choice: Use Azure Virtual Machine Scale Sets for repeatable VM instance scaling. Acceptance should demonstrate: Worker count rises when qualifying demand increases.
Incorrect Answers
A:This setup is relevant to another workload: A video encoder needs GPU-accelerated processing inside a customer-controlled guest. The current configuration must instead achieve: Worker count rises when qualifying demand increases.
C:This change would be appropriate under a different condition: A business needs a managed Kubernetes control plane for many containerized services. Here it would not validate: Worker count rises when qualifying demand increases.
D:This setup is relevant to another workload: A firm deploys a Linux Azure VM and asks what supporting Azure resources it requires. The current configuration must instead achieve: Worker count rises when qualifying demand increases.
Question 375
A retail API must automatically add identical VM workers during holiday traffic. Which verification outcome should the team expect from the right design?
- The chosen service exposes the required host-OS control or abstracts it as specified.
- Planned maintenance does not remove both members at once in the validated model.
- Worker count rises when qualifying demand increases.
- The service runs with the same packaged dependencies in test and production.
Explanation
Correct Answer
C:Worker count rises when qualifying demand increases. That directly tests the stated requirement: A retail API must automatically add identical VM workers during holiday traffic. It contrasts with the observed failure: Operators manually create each VM during every traffic spike.
Incorrect Answers
A:This observation is evidence for a separate scenario: A batch team must distinguish a VM scale set from Azure App Service autoscale. It does not test the necessary outcome here: Worker count rises when qualifying demand increases.
B:That check tests another control: Two critical VMs in one region need separation from common host hardware maintenance faults. The decisive result for this workload is: Worker count rises when qualifying demand increases.
D:This observation is evidence for a separate scenario: A team must package a microservice and its libraries consistently across environments. It does not test the necessary outcome here: Worker count rises when qualifying demand increases.
Question 376
A retail API must automatically add identical VM workers during holiday traffic. The team observes: Operators manually create each VM during every traffic spike. Which underlying mistake most directly explains the reported symptom?
- The design ignored a suitable event-driven managed service.
- An individual unmanaged VM was used instead of a scalable instance group.
- A managed app service was chosen despite the need for VM-level control.
- The VM was assigned a public IP despite private-only requirements.
Explanation
Correct Answer
B:An individual unmanaged VM was used instead of a scalable instance group. That explains the symptom: Operators manually create each VM during every traffic spike. The targeted corrective action is: Deploy a scale set with autoscale and a suitable image configuration.
Incorrect Answers
A:This cause is consistent with a different issue: A full-time VM waits idle for rare messages. It does not account for the reported symptom here: Operators manually create each VM during every traffic spike.
C:That explanation belongs to a different fault pattern: The application host does not permit required guest OS changes. It does not explain why operators manually create each VM during every traffic spike.
D:This cause is consistent with a different issue: A security review finds an unnecessary internet-reachable address. It does not account for the reported symptom here: Operators manually create each VM during every traffic spike.
Question 377
Two critical VMs in one region need separation from common host hardware maintenance faults. What is the most appropriate cloud concept or service for this need?
- Use network security group rules to filter allowed inbound network traffic.
- Use a container image for portable application packaging.
- Consider Azure Container Apps for eligible managed application containers.
- Evaluate an Azure availability set where it meets the workload's resilience needs.
Explanation
Correct Answer
D:Evaluate an Azure availability set where it meets the workload's resilience needs. The governing requirement is: Two critical VMs in one region need separation from common host hardware maintenance faults. This solution specifically supports the outcome that planned maintenance does not remove both members at once in the validated model.
Incorrect Answers
A:This design is appropriate for a different requirement: A security administrator wants to allow HTTPS but block unsolicited remote management to a VM. Here the decisive outcome must instead be: Planned maintenance does not remove both members at once in the validated model.
B:That concept addresses this separate situation: A team must package a microservice and its libraries consistently across environments. It does not by itself establish the result required here: Planned maintenance does not remove both members at once in the validated model.
C:This option solves a different planning problem: A developer wants a simple containerized web API without managing a Kubernetes cluster. The current acceptance criterion is specific: Planned maintenance does not remove both members at once in the validated model.
Question 378
Two critical VMs in one region need separation from common host hardware maintenance faults. What should the team configure or perform to implement the correct approach?
- Create the required public DNS zone and supported record set.
- Deploy the supported web runtime and set application configuration.
- Place the appropriate VMs in one availability set with separate fault/update domains.
- Select VMSS for guest-managed worker images and App Service for eligible web apps.
Explanation
Correct Answer
C:Place the appropriate VMs in one availability set with separate fault/update domains. The implementation operationalizes this design choice: Evaluate an Azure availability set where it meets the workload's resilience needs. Acceptance should demonstrate: Planned maintenance does not remove both members at once in the validated model.
Incorrect Answers
A:This setup is relevant to another workload: An administrator wants hostnames in a company's own domain to resolve to Azure services. The current configuration must instead achieve: Planned maintenance does not remove both members at once in the validated model.
B:That action implements a different requirement: An e-commerce team has a simple website and does not want to patch guest OS hosts. It does not establish the required result in this case: Planned maintenance does not remove both members at once in the validated model.
D:This setup is relevant to another workload: A batch team must distinguish a VM scale set from Azure App Service autoscale. The current configuration must instead achieve: Planned maintenance does not remove both members at once in the validated model.
Question 379
Two critical VMs in one region need separation from common host hardware maintenance faults. Which evidence best confirms the requirement is being met?
- Authorized HTTPS requests work while prohibited management attempts fail.
- The client resolves and reaches the database via private address.
- Planned maintenance does not remove both members at once in the validated model.
- VNet clients resolve internal hostnames to private addresses.
Explanation
Correct Answer
C:Planned maintenance does not remove both members at once in the validated model. That directly tests the stated requirement: Two critical VMs in one region need separation from common host hardware maintenance faults. It contrasts with the observed failure: Both critical VMs are interrupted by a shared maintenance event.
Incorrect Answers
A:This observation is evidence for a separate scenario: A security administrator wants to allow HTTPS but block unsolicited remote management to a VM. It does not test the necessary outcome here: Planned maintenance does not remove both members at once in the validated model.
B:That check tests another control: An internal application must reach an Azure PaaS database by private IP without public service exposure. The decisive result for this workload is: Planned maintenance does not remove both members at once in the validated model.
D:This observation is evidence for a separate scenario: A private VNet workload needs internal name resolution not exposed to public DNS. It does not test the necessary outcome here: Planned maintenance does not remove both members at once in the validated model.
Question 380
Two critical VMs in one region need separation from common host hardware maintenance faults. The team observes: Both critical VMs are interrupted by a shared maintenance event. What is the most likely cause of the observed failure?
- It conflated endpoint resource types and their accessibility semantics.
- The deployment included a VM object without required supporting resources.
- They used public exposure instead of private hybrid network connectivity.
- They were not placed in the intended availability-set fault/update separation.
Explanation
Correct Answer
D:They were not placed in the intended availability-set fault/update separation. That explains the symptom: Both critical VMs are interrupted by a shared maintenance event. The targeted corrective action is: Place the appropriate VMs in one availability set with separate fault/update domains.
Incorrect Answers
A:This cause is consistent with a different issue: The design treats a private endpoint as an internet-accessible public IP. It does not account for the reported symptom here: Both critical VMs are interrupted by a shared maintenance event.
B:The alternate mechanism would more directly produce this other failure: A VM declaration fails because essential network/disk prerequisites are absent. The current incident instead involves: Both critical VMs are interrupted by a shared maintenance event.
C:That explanation belongs to a different fault pattern: Administrators publish the internal service on a public endpoint for office access. It does not explain why both critical VMs are interrupted by a shared maintenance event.
