Azure Files

Answer

Azure Cosmos DB

Question 5

A company is deploying a multi-tier web application on Azure VMs. The web tier must be accessible from the internet, while the application and database tiers must be isolated within the virtual network. The solution must provide SSL termination, web application firewall (WAF) capabilities, and URL-based routing. Which Azure service should they use to expose the web tier?

Accepted Answer

Use Azure Application Gateway with WAF, and configure NSGs to restrict traffic between tiers.. Azure Application Gateway is a Layer 7 load balancer that provides SSL termination, a web application firewall (WAF), and URL-based routing, making it ideal for exposing a web tier to the internet. By placing the gateway in front of the web tier and configuring network security groups (NSGs) on the application and database subnets, you can isolate internal tiers while meeting all stated requirements.

Answer

Use an Azure Load Balancer and configure NSGs on each subnet.

Answer

Use Azure Firewall to inspect all traffic and allow internet traffic to the web tier.

Answer

Use Azure Front Door to expose the web tier and NSGs for internal isolation.

Question 6

A company is building a petabyte-scale data lake for analytics. They need a storage solution that supports a hierarchical namespace, POSIX-like permissions (ACLs), and is optimized for big data analytics workloads using Apache Spark and Hive. The data must be accessible over the Azure Blob Storage API. Which Azure data service should they use?

Accepted Answer

Azure Data Lake Storage Gen2. Azure Data Lake Storage Gen2 (ADLS Gen2) is the correct choice because it combines a hierarchical namespace with POSIX-like ACLs and is natively optimized for big data analytics workloads like Apache Spark and Hive. It exposes data through the Azure Blob Storage API, meeting all stated requirements for petabyte-scale analytics.

Answer

Azure Blob Storage (with flat namespace)

Answer

Azure NetApp Files

Answer

Azure HPC Cache

Question 7

A company runs a mission-critical SQL Server database on an Azure virtual machine using SQL Server Standard Edition. They need a disaster recovery solution that replicates the database to a secondary Azure region with a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour. The solution must support non-disruptive disaster recovery drills. The company cannot modify the SQL Server configuration or use Always On features due to licensing constraints. Which Azure service should they use?

Accepted Answer

Azure Site Recovery. Azure Site Recovery (ASR) replicates the entire VM (including the SQL Server database) to a secondary Azure region, meeting the RPO of 15 minutes and RTO of 1 hour. It supports non-disruptive disaster recovery drills by allowing test failovers in an isolated network without affecting the production environment. ASR does not require any changes to SQL Server configuration or licensing, as it operates at the hypervisor level using continuous replication.

Answer

SQL Server log shipping to a VM in the secondary region

Answer

Azure Backup with cross-region restore

Answer

Azure SQL Database geo-replication

Question 8

A company stores unstructured data such as documents and images in Azure Blob Storage. The data is accessed frequently for the first month, then only rarely for the next year, and after that must be retained for 10 years for compliance. The company wants to minimize storage costs by automatically moving data to the most cost-effective storage tiers. Which Azure Blob Storage feature should they implement?

Accepted Answer

Lifecycle management policies. Lifecycle management policies in Azure Blob Storage allow you to automatically transition blobs to cooler tiers (e.g., from Hot to Cool, then to Archive) based on age or last modification time. This directly matches the requirement to move data from frequent access (first month) to rare access (next year) and then to long-term retention (10 years) while minimizing costs.

Answer

Azure Data Lake Storage access tiers

Soft delete

Answer

Immutability policies

Question 9

A company runs a critical application on Azure VMs and an Azure SQL Managed Instance in a single region. They need a disaster recovery solution with a Recovery Point Objective (RPO) of 5 minutes for the database and a Recovery Time Objective (RTO) of 2 hours for the entire stack. They want to minimize cost and use native Azure services. Which combination should they implement?

Accepted Answer

Azure Site Recovery for VMs and auto-failover groups for the database. Option C is correct because Azure Site Recovery (ASR) provides orchestrated replication and failover for Azure VMs, meeting the 2-hour RTO for the entire stack, while auto-failover groups for Azure SQL Managed Instance enable automatic, synchronous or asynchronous replication with an RPO as low as 5 minutes using the built-in distributed availability groups feature. This combination uses native Azure services without manual scripting, minimizing cost and complexity.

Answer

Azure Backup for VMs and auto-failover groups for the database

Answer

Deploy a second region with VMs and database replicas manually configured and Azure Traffic Manager

Question 10

A company runs a critical multi-tier application on Azure VMs. The application includes a database tier that requires recovery across multiple VMs at the same point in time. The company uses Azure Site Recovery (ASR) for disaster recovery to a secondary region. The recovery point objective (RPO) is 15 minutes and the recovery time objective (RTO) is 1 hour. The database VMs have a high data change rate, and the company wants to minimize replication costs. Which combination of ASR configurations should they implement?

Accepted Answer

Use multi-VM consistency groups and set the replication frequency to 15 minutes.. Option A is correct because multi-VM consistency groups in Azure Site Recovery ensure that all VMs in the group are recovered to the same crash-consistent point in time, which meets the requirement for cross-VM recovery. Setting the replication frequency to 15 minutes aligns with the 15-minute RPO while minimizing replication costs by avoiding more frequent replication (e.g., 5 minutes) that would increase bandwidth and storage costs.

Answer

Enable application-consistent recovery for all VMs and use ExpressRoute.

Answer

Use standard recovery plans and default replication policy.

Answer

Configure a single recovery plan with manual failover and use Premium SSD managed disks.
