Question 186

You have an Azure application that uses the services shown in the following table. How should you calculate the composite SLA for the application?

A. 0.999 * 0.9999 = 0.9989001 = 99.89001%

B. 0.999 / 0.9999 = 0.9991 = 99.91%

C. Max(0.999, 0.9999) = 0.9999 = 99.99%

D. Min(0.999, 0.9999) = 0.999 = 99.9%

Show Answer

Correct Answer: A

Explanation:
For an application composed of dependent services in series, the composite SLA is calculated by multiplying the individual SLAs. Here, 99.9% (0.999) × 99.99% (0.9999) = 0.9989001, which equals 99.89001%. This reflects that the application is available only when all components are available.

Question 187

You need to purchase a third-party virtual security appliance that you will deploy to an Azure subscription. What should you use?

A. Azure subscriptions

B. Azure Security Center

C. Azure Marketplace

D. Microsoft Store

Show Answer

Correct Answer: C

Explanation:
A third-party virtual security appliance for Azure is purchased and deployed through Azure Marketplace, which hosts certified third-party solutions designed to integrate directly with Azure subscriptions. The other options do not provide a way to buy third-party virtual appliances.

Question 188

What can you use to identify underutilized or unused Azure virtual machines?

A. Azure Advisor

B. Azure Cost Management + Billing

C. Azure reservations

D. Azure Policy

Show Answer

Correct Answer: A

Explanation:
Azure Advisor analyzes resource utilization using telemetry and machine-learning–based insights to provide optimization recommendations. It explicitly identifies underutilized or unused virtual machines and recommends actions such as resizing or shutting them down. Azure Cost Management + Billing focuses on cost and spend analysis rather than utilization optimization, while Azure Reservations and Azure Policy do not identify underutilized VMs.

Question 190

Your company plans to migrate all on-premises data to Azure. You need to identify whether Azure complies with the company's regional requirements. What should you use?

A. the Knowledge Center

B. Azure Marketplace

C. the MyApps portal

D. the Trust Center

Show Answer

Correct Answer: D

Explanation:
To verify whether Azure meets regional, regulatory, and compliance requirements, you should use the Microsoft Trust Center. It provides detailed information about Azure’s compliance with global, regional, and industry-specific standards, certifications, and data residency commitments.

Question 191

You have an Azure Sentinel workspace. You need to automate responses to threats detected by Azure Sentinel. What should you use?

A. adaptive network hardening in Azure Security Center

B. Azure Service Health

C. Azure Monitor workbooks

D. adaptive application controls in Azure Security Center

Show Answer

Correct Answer:

Explanation:
Automated responses in Microsoft Sentinel are implemented using playbooks, which are built on Azure Logic Apps. Azure Monitor Workbooks are for visualization and reporting only, not automation. Azure Service Health is unrelated, and adaptive network hardening or adaptive application controls belong to Azure Security Center/Defender for Cloud, not Sentinel response automation. Therefore, none of the provided options correctly address automating responses to Sentinel-detected threats.

Question 192

What is the most severe failure from which an Azure Availability Zone can be used to protect access to Azure service?

A. a physical server failure

B. an Azure region failure

C. a storage failure

D. an Azure data center failure

Show Answer

Correct Answer: D

Explanation:
Azure Availability Zones are physically separate locations within an Azure region, each made up of one or more datacenters with independent power, cooling, and networking. They are designed to maintain service availability if a single datacenter fails. They do not protect against an entire region failure, which would impact all zones. Therefore, the most severe failure an Availability Zone protects against is a datacenter failure.

Show Answer

Correct Answer: Microsoft Privacy Statement Online Services Terms Data Protection Addendum

Explanation:
The Microsoft Privacy Statement explains what personal data is collected and how it is used. The Online Services Terms are the legal agreement defining obligations between Microsoft and customers for processing and security of customer and personal data. The Data Protection Addendum further defines detailed data processing and security terms for online services, including disclosure, transfer, retention, and deletion.

Question 195

HOTSPOT - For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:

Show Answer

Correct Answer: No No Yes

Explanation:
Public clouds do not accept a customer’s own physical servers; they provide provider-owned infrastructure. A private cloud may be internet-connected; isolation is logical, not mandatory disconnection. A hybrid cloud by definition includes a public cloud component.

Question 196

HOTSPOT - Select the answer that correctly completes the sentence. Hot Area:

Show Answer

Correct Answer: is a distinct separate instance of Microsoft Azure.

Explanation:
Azure China is physically and logically isolated from Azure Global and is operated independently (by 21Vianet) to comply with Chinese regulations, so it is not operated by Microsoft directly and does not have full feature parity.
