AZ-104 Exam Dumps - Microsoft Azure Administrator

As App1 is public-facing we need an incoming security rule, related to the access of the web servers.

Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers: a SQL database, a web front end, and a processing middle tier.

Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only.

Box 1: Selected

Only selected users should be able to join devices

Box 2: Yes

Require Multi-Factor Auth to join devices.

From scenario:

Ensure that only users who are part of a group named Pilot can join devices to Azure AD

Ensure that when users join devices to Azure Active Directory (Azure AD), the users use a mobile phone to verify their identity.

In Azure, Load Balancers distribute network traffic across multiple virtual machines (VMs) to ensure high availability and reliability. To add virtual machines to the backend pool of an Azure Load Balancer, the following key conditions must be met according to the Microsoft Azure Administrator documentation:

All VMs in the backend pool must be connected to the same virtual network (VNet) as the Load Balancer.

The Load Balancer (in this case, LB1) is configured for internal load balancing on VNET1/Subnet1 as per the technical requirements of the case study.

The backend pool can include network interfaces (NICs) from VMs within the same region and VNet.

Step-by-step analysis:

—

Observation:

VM1 is already connected to VNET1/Subnet1, where the internal Load Balancer LB1 is also deployed.

VM2, however, is connected to VNET1/Subnet2, which is a different subnet within the same virtual network.

According to Microsoft Learn (“Configure backend pools in Azure Load Balancer”):

“All network interfaces in the backend pool must be within the same virtual network as the load balancer. You cannot add VMs connected to different VNets or subnets not associated with the load balancer’s front-end configuration.”

Therefore, before you can add VM2 to the backend pool, you must ensure that its network interface is attached to VNET1/Subnet1, the same subnet used by LB1.

Only after this step will both VMs (VM1 and VM2) be eligible for inclusion in LB1’s backend pool.

Incorrect Option Analysis:

A. Create a new NSG and associate the NSG to VNET1/Subnet1.

❌ Not required. Network Security Groups control traffic filtering, not backend pool configuration.

C. Redeploy VM1 and VM2 to the same availability zone.

❌ Availability Zones only matter for redundancy and failover, not for backend pool eligibility in a basic internal load balancer.

D. Redeploy VM1 and VM2 to the same availability set.

❌ Basic Load Balancers can distribute traffic across VMs in the same availability set, but both VMs must already reside in the same VNet/Subnet first.

Final Verified Answer:

✅ B. Connect VM2 to VNET1/Subnet1

In this scenario, App1 consists of three distinct tiers — web front end, processing middle tier, and SQL database — each containing five virtual machines. The technical requirement specifies that the company must minimize the number of open ports between the App1 tiers, move all tiers of App1 to Azure, and ensure that all VMs are protected by backups.

According to Microsoft Azure architecture best practices for multi-tier applications (from Azure Architecture Center and the Azure Administrator curriculum), the optimal design involves:

Deploying all tiers of App1 into a single virtual network (VNet).

This allows all components of the application to communicate securely using private IP addresses.

Keeping all tiers within a single VNet simplifies management, security, and monitoring while supporting Network Security Groups (NSGs) for inter-tier traffic control.

Microsoft Documentation Extract:

“Use a single virtual network to host multi-tier applications. Divide the virtual network into multiple subnets, each representing a tier, and use network security groups (NSGs) to control traffic flow between tiers.”

(Source: Microsoft Learn – Design and implement virtual networks in Azure)

Creating separate subnets for each application tier (3 total).

Subnet 1: Web tier (internet-facing, HTTPS traffic)

Subnet 2: Application/Processing tier (internal communication only)

Subnet 3: Database tier (private, no internet access)

Using NSGs, administrators can explicitly allow or deny traffic between subnets, thus minimizing open ports between tiers and meeting the security requirement.

Microsoft Documentation Extract:

“Subnets provide isolation and segmentation within a virtual network. Each tier of an application should be deployed in its own subnet to apply network security policies and control exposure.”

(Source: Microsoft Learn – Azure virtual network design best practices)

Backups and Storage Requirements:

All VMs can use Azure Backup integrated with Recovery Services Vaults, which supports VM-level backup in a single VNet environment.

The blueprint files are stored in Azure Blob Storage with the archive tier, ensuring compliance with the storage and access control requirements.

By using one virtual network and three subnets, Contoso ensures efficient management, minimized administrative overhead, secure isolation of application tiers, and full compliance with Azure governance and security recommendations.

✅ Final Verified Answer:

Number of virtual networks: 1

Number of subnets: 3

A Recovery Services vault is a logical container that stores the backup data for each protected resource, such as Azure VMs. When the backup job for a protected resource runs, it creates a recovery point inside the Recovery Services vault.

Scenario:

There are three application tiers, each with five virtual machines.

Move all the virtual machines for App1 to Azure.

Ensure that all the virtual machines for App1 are protected by backups.

Active Directory Federation Services is a feature and web service in the Windows Server Operating System that allows sharing of identity information outside a company’s network.

Scenario: Technical Requirements include:

Prevent user passwords or hashes of passwords from being stored in Azure.

Statement 1: Yes

Contoso is moving the existing product blueprint files to Azure Blob storage which will ensure that the blueprint files are stored in the archive storage tier.

Use unmanaged standard storage for the hard disks of the virtual machines. We use Page Blobs for these.

Statement 2: No

Azure Table storage stores large amounts of structured data. The service is a NoSQL datastore which accepts authenticated calls from inside and outside the Azure cloud. Azure tables are ideal for storing structured, non-relational data. Common uses of Table storage include:

1. Storing TBs of structured data capable of serving web scale applications

2. Storing datasets that don ' t require complex joins, foreign keys, or stored procedures and can be denormalized for fast access

3. Quickly querying data using a clustered index

4. Accessing data using the OData protocol and LINQ queries with WCF Data Service .NET Libraries

Statement 3: No

File Storage can be used if your business use case needs to deal mostly with standard File extensions like *.docx, *.png and *.bak then you should probably go with this storage option.

In this scenario, Contoso Ltd. must designate a new user named Admin1 as the service administrator of the Azure subscription and ensure that Admin1 receives email alerts about service outages.

In Azure, there are three classic administrative roles associated with subscriptions:

Account Administrator – The individual who created the subscription and manages billing.

Service Administrator – The primary contact responsible for managing services and resources in the subscription.

Co-Administrator – Has the same management privileges as the Service Administrator but cannot change subscription associations.

According to Microsoft Azure Administrator documentation, to change the Service Administrator, you must perform the following steps:

In the Azure portal, navigate to Subscriptions.

Select the specific subscription.

Under Settings, choose Properties.

In the Service Administrator field, update the name and email address to that of the new administrator (in this case, Admin1).

This modification ensures that Admin1 becomes the Service Administrator, and Azure will automatically send service-related notifications and outage alerts to that user’s registered email address, as defined by Microsoft’s subscription notification process.

Option B (IAM settings) is used for Role-Based Access Control (RBAC) and assigning Azure Resource Manager roles such as Owner, Contributor, or Reader. However, RBAC roles do not change the Service Administrator at the subscription level — that’s only done through the Properties blade.

Options C (AAD Properties) and D (AAD Groups) are unrelated to subscription-level administrative settings.

Therefore, the verified and Microsoft-documented answer is:

✅ A. From the Subscriptions blade, select the subscription, and then modify the Properties.

Final Verified Answer: ✅ A. From the Subscriptions blade, select the subscription, and then modify the Properties.
