How many copies of data are maintained by an Azure Storage account that uses geo-redundant storage (GRS)?
A. 3
B. 4
C. 6
D. 9
Show Answer
Correct Answer: C
Explanation: Geo-redundant storage (GRS) stores three locally redundant copies in the primary region and asynchronously replicates them to a secondary region, where three more locally redundant copies are maintained. This results in a total of six copies of the data.

Correct Answer: perimeter layer
Explanation: In Azure's Defense in Depth model, Azure DDoS Protection is categorized as a perimeter-layer control that helps stop large-scale attacks before they reach internal resources. Although DDoS mitigates Layer 3/4 traffic technically, the exam refers to the Defense in Depth layers, not the OSI model.
Question 167
You have an accounting application named App1 that uses a legacy database.
You plan to move App1 to the cloud.
Which service model should you use?
A. platform as a service (PaaS)
B. infrastructure as a service (IaaS)
C. software as a service (SaaS)
Show Answer
Correct Answer: B
Explanation: IaaS is the best fit for migrating an existing application that depends on a legacy database because it provides full control over the operating system, virtual machines, storage, and networking. This supports a lift-and-shift migration with minimal changes. PaaS typically requires adapting the application or using managed platform services, while SaaS is a complete software solution rather than a hosting model.
Question 168
What are two benefits of cloud computing? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. enables the rapid provisioning of resources
B. has increased administrative complexity
C. has the same configuration options as on-premises
D. shifts capital expenditures (CAPEX) to operating expenditures (OPEX)
Show Answer
Correct Answer: A, D
Explanation: Cloud computing enables rapid provisioning and scaling of resources on demand, reducing deployment time. It also changes spending from upfront capital investments (CAPEX) to pay-as-you-go operating expenses (OPEX). Increased administrative complexity is not a benefit, and cloud services do not necessarily have the same configuration options as on-premises environments.
Question 169
HOTSPOT -
You plan to use Azure to host two apps named App1 and App2. The apps must meet the following requirements:
✑ You must be able to modify the code of App1.
✑ Administrative effort to manage the operating system of App1 must be minimized.
✑ App2 must run interactively with the operating system of the server.
Which type of cloud service should you use for each app? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Show Answer
Correct Answer: App1: Platform as a Service (PaaS)
App2: Infrastructure as a Service (IaaS)
Explanation: PaaS lets you deploy and modify application code while the platform manages the operating system, minimizing OS administration. IaaS provides control over the server operating system, allowing applications to interact directly with it.

Correct Answer: disaster recovery
Explanation: Azure Site Recovery (ASR) is Microsoft's disaster recovery as a service (DRaaS) solution. It replicates and orchestrates failover/recovery of virtual machines; it does not provide fault tolerance or high availability.
Question 171
HOTSPOT -
You create a resource group named RG1 in Azure Resource Manager.
You need to prevent the accidental deletion of the resources in RG1.
Which setting should you use? To answer, select the appropriate setting in the answer area.
Hot Area:
Show Answer
Correct Answer: Locks
Explanation: Use a resource lock (Delete lock/CanNotDelete) on the resource group to prevent accidental deletion of the resource group and its resources.

Show Answer
Correct Answer: Yes
Yes
No
Explanation: Azure Policy can automatically add or modify tags through policy effects. A resource can have multiple tags. Resources do not automatically inherit tags from their resource group; inheritance requires Azure Policy.
Question 173
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 services connected in series where the application depends on all components being available, the composite SLA is the product of the individual SLAs. Thus, 0.999 × 0.9999 = 0.9989001, or 99.89001%. This is lower than either individual SLA because any component outage can make the application unavailable.
