Question 30

You need to migrate an on-premises server by using a lift-and-shift migration. To which type of cloud service should you migrate?

A. infrastructure as a service (IaaS)
B. software as a service (SaaS)
C. platform as a service (PaaS)
Show Answer
Correct Answer: A
Explanation:
A lift-and-shift migration (also called rehosting) moves existing servers and workloads to the cloud with minimal or no changes. This approach maps directly to Infrastructure as a Service (IaaS), where you migrate on‑premises servers to cloud-based virtual machines while retaining control over the OS, applications, and configurations. SaaS and PaaS require application redesign or replacement, which contradicts lift‑and‑shift.

Question 31

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.

Illustration for AZ-900 question 31
Show Answer
Correct Answer: No Yes No
Explanation:
Azure resources can have multiple tags as key-value pairs. Tags can be defined and applied through Azure Resource Manager (ARM) templates. Tags are for organization and categorization; naming standards are enforced using Azure Policy, not tags.

Question 33

DRAG DROP - Match the Azure compute services to the appropriate descriptions. To answer, drag the appropriate compute service from the column on the left to its description on the right. Each service may be used once, more than once, or not at all. NOTE: Each correct match is worth one point.

Illustration for AZ-900 question 33
Show Answer
Correct Answer: Provides software emulation of a physical computer: Azure Virtual Machine Scale Sets Provides operating system virtualization: Azure Container Instances
Explanation:
Virtual machines emulate physical hardware (CPU, memory, disks), which is provided by Azure Virtual Machine Scale Sets. Containers virtualize the operating system layer, which is provided by Azure Container Instances.

Question 36

You have an Azure Storage account named storage1. You need to ensure that containers can be created in, but not deleted from, storage1. What should you do?

A. Create a ReadOnly lock for storage1.
B. Create a delete lock for storage1.
C. Enable container soft delete.
D. Enable blob soft delete.
Show Answer
Correct Answer: B
Explanation:
An Azure resource delete lock (CanNotDelete) prevents deletion of the storage account or its child resources while still allowing normal operations such as creating containers. A ReadOnly lock would block all changes, and soft delete options apply to data recovery after deletion rather than preventing deletion.

Question 38

HOTSPOT - Select the answer that correctly completes the sentence.

Illustration for AZ-900 question 38
Show Answer
Correct Answer: for data that is accessed infrequently and stored for at least 30 days.
Explanation:
The Azure Blob Storage Cool access tier is designed for infrequently accessed data with a minimum storage duration of 30 days, offering lower storage costs than Hot but higher access costs.

Question 39

In the software as a service (SaaS) cloud service, which responsibility is shared between Microsoft and the customer?

A. identity and directory infrastructure management
B. application management
C. information and data management
D. operating system updates
Show Answer
Correct Answer: A
Explanation:
In the SaaS shared responsibility model, Microsoft manages the application, operating system, and underlying infrastructure, while the customer manages their users and access. Identity and directory infrastructure management (such as user accounts, roles, and access control) is therefore shared between Microsoft and the customer. Application management and OS updates are handled by Microsoft, and information and data management is the customer’s responsibility alone.

Question 40

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.

Illustration for AZ-900 question 40
Show Answer
Correct Answer: Same subscription: No Different regions: No Different subscriptions: No
Explanation:
Azure Storage account names must be globally unique across all of Azure because the name is part of the public service URL. Therefore, the same name cannot be reused in the same subscription, across regions, or across different subscriptions.

Question 41

HOTSPOT - Select the answer that correctly completes the sentence.

Illustration for AZ-900 question 41
Show Answer
Correct Answer: Azure Service Health
Explanation:
Azure Service Health provides a global view of the health status of Azure services, regions, and specific resources, including outages, incidents, and planned maintenance.

Question 42

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.

Illustration for AZ-900 question 42
Show Answer
Correct Answer: No No Yes
Explanation:
Adding RAM to a VM is vertical scaling, not horizontal. Adding another VM is horizontal scaling, not vertical. Horizontal scaling can be performed either manually or automatically (autoscale).
