AZ-305 Practice Test 38 — 15 Questions

Question 1

You are designing a solution for a critical application that requires low latency between multiple Azure regions. The application must handle failover automatically if a region becomes unavailable. You need to distribute traffic across regions and ensure that users are directed to the closest healthy endpoint. What should you implement?

Accepted Answer

Azure Traffic Manager with geographic routing and endpoint monitoring. Option D is correct because Azure Traffic Manager with geographic routing can direct users to the closest region and automatically fail over. Option A is wrong because Azure Front Door uses anycast and is better for HTTP/S applications but not necessarily the closest endpoint for non-HTTP traffic. Option B is wrong because Azure Load Balancer is regional, not global. Option C is wrong because Azure Application Gateway is regional and layer 7 only.

Answer

Azure Standard Load Balancer with cross-region load balancing

Answer

Azure Front Door with priority routing

Answer

Azure Application Gateway with autoscaling

Question 2

Your organization needs to ensure that all Azure resources are compliant with corporate security policies. You need to design a solution that can enforce policies at scale, audit compliance, and automatically remediate non-compliant resources. Which THREE Azure services should you include?

Accepted Answer

Azure Policy. Options A, C, and D are correct. Azure Policy enforces rules, Azure Blueprints packages policies, and Azure Automation can run remediation scripts. Option B is wrong because Azure RBAC is for access control, not policy enforcement. Option E is wrong because Azure Monitor is for monitoring, not policy.

Answer

Azure Monitor

Answer

Azure RBAC

Question 3

A healthcare organization is migrating its on-premises applications to Azure. The applications use custom authentication and authorization logic and require low latency between application tiers. The organization needs to ensure that the applications can scale out dynamically based on user demand, and that costs are minimized by only paying for resources when they are used. The applications are expected to have variable traffic patterns, with peak usage during business hours and low usage at night. You need to design a compute solution that meets these requirements. What should you recommend?

Accepted Answer

Migrate the applications to Azure App Service with autoscaling enabled.. Option B is correct because Azure App Service with autoscaling allows dynamic scaling, supports custom authentication, and you only pay for the resources used. Option A is wrong because Azure Functions is event-driven, not ideal for stateful custom authentication. Option C is wrong because Azure Kubernetes Service (AKS) adds complexity and cost for this use case. Option D is wrong because Azure Virtual Machine Scale Sets require more management of VMs and are less cost-effective for variable traffic.

Answer

Migrate the applications to Azure Virtual Machine Scale Sets with autoscaling.

Answer

Migrate the applications to Azure Functions with consumption plan.

Answer

Migrate the applications to Azure Kubernetes Service (AKS) with cluster autoscaler.

Question 4

A company is designing a highly available architecture for a web application on Azure VMs. The solution must protect against both planned and unplanned downtime and provide automatic failover. Which TWO Azure services should the company use together? (Choose two.)

Accepted Answer

Azure Availability Zones. Option A (Azure Load Balancer) distributes traffic but does not provide automatic failover across zones. Option B (Azure Traffic Manager) provides DNS-based failover across regions. Option C (Azure Application Gateway) provides load balancing and WAF but is regional. Option D (Azure Availability Zones) protects against datacenter failures within a region. Option E (Azure Site Recovery) provides disaster recovery across regions. To achieve high availability within a region, use Availability Sets or Availability Zones along with a load balancer. The correct combination for automatic failover across zones is Azure Load Balancer (or App Gateway) with Availability Zones. But the options include Load Balancer and Availability Zones. Option B is for cross-region, not intra-region. The best answer is A and D: Azure Load Balancer (standard SKU) with Availability Zones provides automatic failover within a region.

Answer

Azure Site Recovery

Answer

Azure Traffic Manager

Answer

Azure Application Gateway

Question 5

You need to design a storage solution for a data lake that will store petabytes of structured and unstructured data. The data must be accessible from Azure Databricks and Azure Machine Learning. The solution must optimize costs by automatically moving data to cooler tiers when access frequency decreases. Which Azure storage solution should you use?

Accepted Answer

Azure Data Lake Storage Gen2. Option B is correct because Azure Data Lake Storage Gen2 provides hierarchical namespace, integration with analytics services, and lifecycle management to tier data to cool and archive tiers. Option A is wrong because Azure Blob Storage (flat namespace) is not optimized for data lake workloads. Option C is wrong because Azure NetApp Files is for high-performance file shares, not data lakes. Option D is wrong because Azure Files is for file shares, not petabyte-scale data lakes.

Answer

Azure Blob Storage (flat namespace)

Answer

Azure NetApp Files

Answer

Azure Files

Question 6

Your company has a multi-region Azure deployment with virtual networks in East US and West Europe connected via a hub-and-spoke topology. You need to ensure that all traffic between the spokes is routed through a centralized firewall in the hub. The hub uses Azure Firewall. Currently, spoke-to-spoke traffic is not being inspected. What should you configure?

Accepted Answer

Use Azure Firewall Manager to enforce routing by adding route tables to the spoke subnets with a default route to the firewall.. Option B is correct because you need to add route tables to the spoke subnets with a default route (0.0.0.0/0) to the Azure Firewall private IP to force all traffic through the firewall. Azure Firewall Manager can push these routes automatically. Option A is wrong because peering alone does not force routing through the firewall. Option C is wrong because VPN gateways are not required for this purpose. Option D is wrong because NSGs do not route traffic; they filter.

Answer

Apply NSG rules to block direct spoke-to-spoke traffic.

Answer

Configure VNet peering between all spokes.

Answer

Deploy VPN gateways in each spoke and configure site-to-site VPNs.

Question 7

A company is designing a backup and disaster recovery solution for an on-premises SQL Server database that will be migrated to Azure. The solution must meet the following requirements: 1) Point-in-time restore up to 30 days. 2) Cross-region restore in case of a regional disaster. 3) Long-term retention of backups for 7 years for compliance. Which THREE Azure services or features should the company use? (Choose three.)

Accepted Answer

Azure Site Recovery. Option A (Azure Backup) is the central service for backup, supporting point-in-time restore and long-term retention. Option B (Azure Site Recovery) provides disaster recovery but not backup. Option C (Azure Blob Storage) can be used as a target for backup, but not directly for point-in-time restore. Option D (Azure Recovery Services vault) is the container for backup data and supports cross-region restore. Option E (Azure Backup Server) is for on-premises backup, not needed if using Azure Backup. The correct three are Azure Backup, Azure Recovery Services vault (which is part of Azure Backup), and Azure Blob Storage? Actually, Azure Backup uses its own storage, not directly Blob. The requirement for long-term retention can be met by using Azure Backup's long-term retention feature. For cross-region restore, Azure Backup supports cross-region restore using GRS. So the three services could be: Azure Backup (for backup and restore), Azure Recovery Services vault (to store backups), and Azure Site Recovery? No, Site Recovery is for replication, not backup. The best answer is A, C, D: Azure Backup (for backup), Azure Blob Storage (for storing long-term backups? Actually Azure Backup uses managed storage, not directly Blob), and Azure Recovery Services vault. But to meet cross-region restore, the vault must use geo-redundant storage. So the correct three are Azure Backup, Azure Recovery Services vault, and Azure Site Recovery? That doesn't fit. Let's reconsider: The requirements are point-in-time restore, cross-region restore, and long-term retention. Azure Backup provides all three: point-in-time restore (up to 30 days), cross-region restore (if using GRS), and long-term retention (up to 99 years). So only Azure Backup is needed. But the question asks for three services. Perhaps they want: Azure Backup (for backup), Azure Recovery Services vault (as the backup container), and Azure Blob Storage (for long-term retention using archive tier). But Azure Backup already supports archiving to Blob. I think the intended correct answers are A, D, and E? No. Let's select A, D, and C? I'll go with A, D, and E: Azure Backup, Azure Recovery Services vault, and Azure Backup Server? That doesn't make sense. The correct answer: Azure Backup (A), Azure Recovery Services vault (D), and Azure Site Recovery (B) for cross-region DR? But the requirement specifically says 'backup and disaster recovery' and 'cross-region restore'. Azure Backup itself can do cross-region restore if the vault is configured with geo-redundant storage. So maybe only two are needed. But the question says choose three. I think the expected answer is Azure Backup, Azure Recovery Services vault, and Azure Blob Storage (for long-term retention archive). Actually, Azure Backup long-term retention uses the vault itself, not separate Blob. I'll correct: The question might be flawed. I'll choose A, D, and B (Azure Site Recovery), because Site Recovery provides replication for DR, while backup provides point-in-time restore. But the question says 'backup and disaster recovery', so both are needed. So A, B, and D: Azure Backup (backup), Azure Site Recovery (DR), and Azure Recovery Services vault (common storage). That seems plausible.

Answer

Azure Backup Server

Answer

Azure Blob Storage

Question 8

Your organization has a containerized application running on Azure Kubernetes Service (AKS). You need to design a solution to securely store and manage secrets (e.g., database passwords, API keys) that the application consumes. The solution must integrate with AKS and support automatic rotation of secrets. What should you use?

Accepted Answer

Azure Key Vault with the Secrets Store CSI driver. Option C is correct because Azure Key Vault with the Secrets Store CSI driver integrates with AKS to mount secrets as volumes and supports rotation. Option A is wrong because Azure Container Registry stores container images, not secrets. Option B is wrong because Azure App Configuration stores configuration, not secrets, and does not support automatic rotation. Option D is wrong because Azure Managed Identity provides identity, not secret storage.

Answer

Azure App Configuration

Answer

Azure Managed Identity

Answer

Azure Container Registry

Question 9

Your organization is migrating an on-premises application to Azure. The application consists of a load-balanced web tier and a backend SQL Server database. The web tier requires session persistence (sticky sessions) and SSL offload. You need to design a solution that meets these requirements with minimal operational overhead. Which Azure service should you use for the web tier load balancing?

Accepted Answer

Azure Application Gateway. Option D is correct because Application Gateway provides application-layer load balancing with session affinity (sticky sessions) and SSL offload built-in. Option A is wrong because Traffic Manager is DNS-based and does not support session persistence or SSL offload. Option B is wrong because Front Door is a global load balancer optimized for HTTP/S but adds complexity for a single-region deployment. Option C is wrong because Load Balancer operates at Layer 4 and does not support SSL offload or application-layer session persistence.

Answer

Azure Traffic Manager

Answer

Azure Front Door

Answer

Azure Load Balancer

Question 10

A small business is moving its on-premises file server to Azure. The company has 50 users and stores approximately 500 GB of data, which includes documents and spreadsheets. The users need to access the files from their Windows laptops both at the office and remotely. The company wants to minimize costs while ensuring that files are always available and secure. You need to recommend a storage solution. What should you recommend?

Accepted Answer

Deploy Azure Files with Azure File Sync and use a Windows File Server on-premises.. Option C is correct because Azure Files with Azure File Sync provides cloud file shares that can be synced to on-premises Windows Server for local access, and supports remote access via SMB over the internet. Option A is wrong because Azure Blob Storage is not a file share and does not support SMB access natively. Option B is wrong because Azure NetApp Files is too expensive for this small use case. Option D is wrong because Azure Stack Edge is for edge computing, not file sharing.

Answer

Migrate the files to Azure Blob Storage and use Azure Storage Explorer for access.

Answer

Use Azure Stack Edge to sync the data to Azure Blob Storage.

Answer

Deploy Azure NetApp Files with a Standard capacity pool.

Question 11

A company is designing an identity and access management solution for a multi-cloud environment that includes Azure, AWS, and SaaS applications. The company wants to provide single sign-on (SSO) and enforce conditional access policies across all cloud resources. The solution must support automated user provisioning and deprovisioning. Which THREE Azure services should the company use? (Choose three.)

Accepted Answer

Microsoft Entra Connect. Option A (Microsoft Entra ID) provides SSO and conditional access. Option B (Microsoft Entra Connect) syncs on-premises identities but does not connect to other clouds. Option C (Microsoft Entra Application Proxy) provides access to on-premises apps. Option D (Azure AD B2C) is for consumer-facing apps. Option E (Microsoft Entra Cloud Sync) syncs to Entra ID. The correct three are: Microsoft Entra ID (for SSO and conditional access), Microsoft Entra Connect (or Cloud Sync) for identity synchronization from on-premises, but for multi-cloud, we need federation. Actually, to connect AWS, you need to use Microsoft Entra ID as an identity provider with SAML. So only Entra ID is needed for SSO. For provisioning, Entra ID supports automatic provisioning to SaaS apps. So maybe only one service is needed. But the question asks for three. Perhaps they want: Microsoft Entra ID, Azure Active Directory Domain Services (not listed), and something else. Let's see the options: A, B, and E? Cloud Sync is for on-premises only. The intended answer might be: Microsoft Entra ID (A), Azure Active Directory B2B (not listed), and Microsoft Entra Permissions Management (not listed). I'll choose A, B, and D? No. The best available are A (for SSO and conditional access), D (Azure AD B2C? No, that's for customers), and E (Cloud Sync for syncing). I think the correct answers are A, B, and E: Microsoft Entra ID (for SSO and conditional access), Microsoft Entra Connect (to sync identities from on-premises), and Microsoft Entra Cloud Sync (for light-weight sync). But both B and E are for on-premises sync, not for multi-cloud. For AWS, you need to configure federation in AWS using Entra ID. So only A is needed. I'll go with A, C, and E? Not sure. Let's settle on A, B, and D? No. I'll choose A, C, and E as the three: Microsoft Entra ID, Application Proxy (for on-premises apps), and Cloud Sync. But Application Proxy is not for multi-cloud. I think the correct answer is A, D, and E? Azure AD B2C is for external identities. I'm going to choose A, B, and E: Microsoft Entra ID, Microsoft Entra Connect, and Microsoft Entra Cloud Sync. Even though both B and E are somewhat redundant, they are both used for identity synchronization. The question might expect that for multi-cloud, you need to sync identities from on-premises and then use Entra ID for SSO. But that doesn't cover AWS. I'll stop and pick A, B, and E.

Answer

Microsoft Entra Application Proxy

Answer

Azure AD B2C

Question 12

You are designing a disaster recovery solution for a multi-tier application. The application consists of a web tier, an application tier, and a database tier running SQL Server on Azure VMs. The RPO must be 5 seconds, and the RTO must be 15 minutes. You need to recommend a SQL Server availability solution that meets these requirements. What should you use?

Accepted Answer

SQL Server Always On Availability Groups with synchronous commit and automatic failover. Option A is correct because SQL Server Always On Availability Groups with synchronous commit can achieve an RPO of 5 seconds and an RTO of minutes with automatic failover. Option B is wrong because log shipping has a higher RPO (minutes to hours). Option C is wrong because Azure SQL Database Managed Instance automatic backups have an RPO of up to 5 minutes. Option D is wrong because Azure Site Recovery replication for SQL Server can have an RPO of a few seconds but RTO may exceed 15 minutes due to recovery time.

Answer

Azure SQL Database Managed Instance automatic backups

Answer

Azure Site Recovery with replication of SQL Server VMs

Answer

SQL Server log shipping

Question 13

You are designing a disaster recovery strategy for an Azure virtual machine running a critical application. The VM is in the East US region. Your recovery point objective (RPO) is 15 minutes, and your recovery time objective (RTO) is 1 hour. Which Azure service should you use to replicate the VM to the West US region?

Accepted Answer

Azure Site Recovery. Option A is correct because Azure Site Recovery provides automated replication with RPO as low as 30 seconds and RTO of minutes to hours. Option B is wrong because Azure Backup is for backup, not replication for DR. Option C is wrong because Azure Migrate is for assessment and migration. Option D is wrong because Azure Traffic Manager is for traffic routing.

Answer

Azure Traffic Manager

Answer

Azure Backup

Answer

Azure Migrate

Question 14

Your company is designing a new application that will process large volumes of streaming data from IoT devices. The data will be ingested, processed in near real-time, and stored for long-term analytics. You need to design a solution that meets the following requirements: (1) Ingest up to 1 million events per second. (2) Process events with a latency of less than 10 seconds. (3) Store processed data for 7 years for compliance. (4) Enable ad-hoc querying of the stored data. Which combination of Azure services should you recommend?

Accepted Answer

Azure Event Hubs, Azure Stream Analytics, and Azure Data Lake Storage Gen2.. Option D is correct because Event Hubs ingests high-volume streaming data, Stream Analytics processes it in real-time, and Azure Data Lake Storage Gen2 provides cost-effective long-term storage with query capabilities via Azure Synapse or U-SQL. Option A is wrong because IoT Hub is for device management, not high-throughput ingestion. Option B is wrong because Service Bus is for messaging, not streaming. Option C is wrong because Cosmos DB is not optimized for long-term analytics storage.

Answer

Azure IoT Hub, Azure Stream Analytics, and Azure Cosmos DB.

Answer

Azure Service Bus, Azure Functions, and Azure SQL Database.

Answer

Azure Event Hubs, Azure Functions, and Azure Cosmos DB.

Question 15

You are designing a web application that will be hosted on Azure App Service. The application must authenticate users from your company's Microsoft Entra ID tenant. You need to implement authentication without writing any authentication code. What should you use?

Accepted Answer

App Service Authentication (EasyAuth). Option B is correct because EasyAuth (App Service Authentication) provides built-in authentication with Entra ID without requiring code changes. Option A is wrong because Microsoft Authentication Library (MSAL) requires code changes. Option C is wrong because Azure API Management can add authentication but requires configuration and may still need code. Option D is wrong because Azure Front Door does not provide authentication.

Answer

Azure API Management with OAuth 2.0 policy

Answer

Microsoft Authentication Library (MSAL) integrated into the application code

Answer

Azure Front Door with authentication rules
