AZ-305 Practice Test 5 — 10 Questions

Question 1

A company plans to migrate a legacy web application to Azure. The application runs on multiple Windows virtual machines (VMs) in an availability set. The VMs must be exposed to the internet via a single endpoint that performs SSL termination and health checks. The load-balancing solution must preserve the original client IP address for logging purposes. Which Azure service should the company use?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Azure Application Gateway v2. Azure Application Gateway v2 is the correct choice because it is a Layer 7 load balancer that supports SSL termination, health probes, and provides a single public endpoint. It preserves the original client IP address by inserting the X-Forwarded-For header in the HTTP request, which the backend VMs can read for logging. This meets all requirements: single internet-facing endpoint, SSL offload, health checks, and client IP preservation.

Answer

Azure Load Balancer (Standard)

Answer

Azure Traffic Manager

Answer

Azure Front Door

Question 2

A company is designing a virtual network architecture for a three-tier application (web, application, database). They want network isolation between tiers and secure access from the internet to the web tier only. Which Azure networking solution should they use?

Accepted Answer

Azure Virtual Network with subnets for each tier and Network Security Groups.. Deploying each tier in its own subnet within an Azure Virtual Network and applying Network Security Groups (NSGs) allows granular inbound/outbound rule enforcement. NSGs can restrict traffic so that only the web tier is reachable from the internet (via a public IP or Azure Load Balancer), while the application and database tiers are isolated from direct internet access and can only communicate with the adjacent tier as defined by NSG rules.

Answer

Azure Virtual Network with a single subnet and application security groups.

Answer

Azure Virtual Network with subnets and Azure Firewall.

Answer

Azure Virtual Network with subnets and a network virtual appliance (NVA).

Question 3

A company wants to allow remote users to access an internal web application hosted on-premises without opening inbound firewall ports. They need seamless single sign-on (SSO) using Microsoft Entra ID credentials. Which Azure service should they use?

Accepted Answer

Microsoft Entra ID Application Proxy. Microsoft Entra ID Application Proxy provides secure remote access to on-premises web applications without requiring inbound firewall ports. It works by establishing an outbound connection from the on-premises Application Proxy connector to the Entra ID service, then routing user traffic through that tunnel. It integrates with Entra ID for pre-authentication and supports seamless SSO using the user's existing Entra ID credentials via Kerberos constrained delegation (KCD) or header-based authentication.

Answer

Microsoft Entra ID B2C

Answer

Microsoft Entra ID Domain Services

Answer

Microsoft Entra ID Connect

Question 4

A company runs a critical application on Azure VMs in the West US region. They need to protect against a regional disaster using Azure Site Recovery. The VMs use unmanaged disks. The recovery point objective (RPO) must be 15 minutes and the recovery time objective (RTO) must be 1 hour. Additionally, they must be able to perform quarterly disaster recovery drills that do not affect the production environment. Which configuration should they use in Azure Site Recovery?

Accepted Answer

Set up replication with a 15-minute snapshot frequency and perform test failover for drills.. Azure Site Recovery supports replication of Azure VMs with unmanaged disks, and a 15-minute snapshot frequency meets the RPO requirement. Test failover allows quarterly disaster recovery drills without impacting the production environment, as it creates isolated copies of VMs in a separate network for validation.

Answer

Use Azure Backup for VM replication and perform restore drills.

Answer

Configure a recovery plan with a pre-script to take a snapshot every 15 minutes.

Answer

Enable multi-VM consistency group with a 15-minute consistency frequency.

Question 5

Your company, Fabrikam Inc., operates a global Software-as-a-Service (SaaS) application that provides real-time analytics. The application runs on Azure Kubernetes Service (AKS) with a microservices architecture. The data tier uses Azure Cosmos DB (Core SQL API) with multi-region writes. The application also uses Azure Event Hubs for event ingestion. The business requires a Recovery Time Objective (RTO) of 10 seconds and a Recovery Point Objective (RPO) of 0 for the entire platform. The solution must support active-active configuration across multiple Azure regions. You have been asked to recommend the disaster recovery design. Which option should you recommend?

Accepted Answer

Deploy AKS in three regions with Azure Front Door. Use Azure Cosmos DB with multi-region writes. Use Azure Event Hubs with geo-disaster recovery and active-active pattern. Use Azure Cache for Redis Enterprise with active geo-replication.. It meets the strict RTO of 10 seconds and RPO of 0 by using Azure Front Door for global load balancing with health probes, Azure Cosmos DB multi-region writes for zero data loss, Azure Event Hubs with geo-disaster recovery and active-active pattern for continuous event ingestion, and Azure Cache for Redis Enterprise with active geo-replication for synchronized caching across regions. This combination ensures that all components support active-active configuration and can fail over instantly without data loss.

Answer

Deploy AKS in three regions with Azure Traffic Manager. Use Azure Cosmos DB with multi-region writes. Use Azure Event Hubs with geo-disaster recovery. Use Azure Cache for Redis Enterprise with active geo-replication.

Answer

Deploy AKS in two regions with Azure Front Door. Use Azure Cosmos DB with single write region and auto-failover. Use Azure Service Bus with geo-disaster recovery. Use Azure Cache for Redis Enterprise with active geo-replication.

Answer

Deploy AKS in two regions with Azure Front Door. Use Azure SQL Database with auto-failover groups. Use Azure Event Hubs with geo-disaster recovery. Use Azure Cache for Redis Enterprise with active geo-replication.

Question 6

You are designing a connectivity solution for a hybrid network. The company has an on-premises network connected to an Azure virtual network via ExpressRoute. They also have a site-to-site VPN to the same Azure virtual network as a backup. When the ExpressRoute connection fails, traffic should automatically fail over to the VPN. How should you configure the routes to ensure automatic failover?

Accepted Answer

Ensure the ExpressRoute connection has a lower BGP metric than the VPN connection; Azure automatically prefers lower metric.. B is correct because when both ExpressRoute and VPN connections use BGP to advertise routes to Azure, Azure automatically selects the route with the lowest BGP metric (MED). By configuring the ExpressRoute connection with a lower BGP metric than the VPN connection, Azure will prefer the ExpressRoute path under normal conditions. If the ExpressRoute fails, its routes are withdrawn, and Azure falls back to the VPN routes, providing automatic failover.

Answer

Configure Azure Traffic Manager with a priority routing method to direct traffic to ExpressRoute first.

Answer

Set the BGP metrics (local preference) on the ExpressRoute connection to be higher than the VPN connection.

Answer

Configure Azure Route Server to propagate routes with a lower metric for the VPN connection.

Question 7

Your company plans to migrate a large number of on-premises virtual machines to Azure. You need to assess the current environment and migrate the workloads with minimal downtime. Which THREE Azure services or tools should you use? (Choose three.)

Accepted Answer

Azure Data Box. Azure Data Box is correct because it enables large-scale offline data transfer for environments with limited network bandwidth, allowing you to migrate terabytes of VM data to Azure without relying on slow or unstable connections. This service is ideal for the initial bulk copy of on-premises VM disks, which can then be used with Azure Migrate for assessment and Azure Site Recovery for ongoing replication with minimal downtime.

Answer

Azure App Service

Answer

Azure Import/Export Service

Question 8

A company is designing a disaster recovery solution for a critical application that runs on Azure VMs in a single region. The RTO is 4 hours, and the RPO is 1 hour. The application uses Azure SQL Database. The company wants to minimize the cost of the disaster recovery solution while meeting the RTO and RPO. You need to recommend a solution. What should you recommend?

Accepted Answer

Use Azure Site Recovery to replicate VMs to a secondary region and Azure SQL Database geo-replication for the database.. Azure Site Recovery provides orchestrated replication and failover for Azure VMs, meeting the 4-hour RTO with automated recovery plans. Azure SQL Database active geo-replication (or failover groups) enables continuous data synchronization with an RPO of 1 hour. This combination minimizes cost by using only the necessary replication services without over-provisioning resources.

Answer

Use Azure SQL Database active geo-replication for the database and Azure Backup for VMs.

Answer

Use Azure Backup to back up VMs and Azure SQL Database to a secondary region.

Answer

Use Azure Traffic Manager to distribute traffic to VMs in multiple regions and Azure SQL Database failover groups.

Question 9

Your company runs a mission-critical application on Azure Virtual Machines in a single region. You need to design a monitoring solution that provides proactive alerts for performance degradation and allows the operations team to analyze historical trends. The solution must minimize cost and operational overhead. You have an existing Log Analytics workspace. What should you include in the design?

Accepted Answer

Enable Azure Monitor on all VMs using the Azure Monitor agent. Create metric alerts for high CPU and memory usage. Use Log Analytics to query and analyze historical performance data.. It uses the Azure Monitor agent to collect performance data from VMs, enabling metric alerts for proactive notification of high CPU and memory usage, while leveraging the existing Log Analytics workspace for cost-effective historical analysis. This approach minimizes operational overhead by using a single agent and native Azure Monitor features without additional services or complex configurations.

Answer

Enable VM insights in Azure Monitor and use its live map and performance views for historical analysis.

Answer

Configure Azure Autoscale for the VMs based on CPU metrics and use Azure Monitor for logging.

Answer

Deploy Application Insights on each VM and use its built-in alerts for performance.

Question 10

You run the above PowerShell script to upload a blob to Azure Storage. The script fails with an error: 'The specified container does not exist.' What should you do first to resolve the issue?

Accepted Answer

Create the container using New-AzStorageContainer.. The error 'The specified container does not exist' indicates that the target container has not been created in the Azure Storage account. The PowerShell script uses the `Set-AzStorageBlobContent` cmdlet, which requires an existing container as the destination. Therefore, the first corrective action is to create the container using `New-AzStorageContainer` before uploading the blob.

Answer

Use a different connection string with a SAS token.

Answer

Grant the storage account key access to the user.

Answer

Change the -StandardBlobTier parameter to Cool.
