Q4 : A company uses Azure SQL Managed Instance for the application data.
What two parameters would you set up to ensure that the instance will scale to meet the workload demands?
A. Define the maximum of CPU cores
B. Define the maximum of the allocated storage
C. Define the maximum of the resources per database
D. Define the maximum resource limit per group of databases
Correct Answers: A and B
Explanation
Azure provides dynamic scalability for the Azure SQL Databases and Azure Managed Instances.
Azure SQL Database service offers two purchasing models: DTU-based and vCore-based. Azure Managed instance service is based only on the vCore purchasing model. This model allows you to select two scalability parameters for managed instance: the maximum CPU cores and the maximum allocated storage.
(Number 1): When you create a SQL Managed instance or change the resources for an existing instance, you use the Compute + storage panel.
(Number 2): Because Azure SQL Managed Instance uses only the vCore model, you need to select one of the model’s Service tier options, General Purpose and Business Critical. These tiers define the storage latency: fast or super fast.
Then, using sliders, you set or change the instance resources: the number of vCores (Number 3) and the storage size (Number 4).
The default values are 8 CPU cores and 256 GB of storage. Azure SQL Managed Instance service will dynamically scale within these parameters to meet the workload demands. All databases in the Azure SQL Managed instance will share the assigned resources.
Option C is incorrect because you need to define a maximum of the resources per database to scale Azure SQL Database for both purchasing models dynamically but not for the Azure SQL Managed Instance scaling.
Option D is incorrect because you need to define a resource limit per group of databases to scale Azure SQL Database Elastic pools dynamically but not for the Azure SQL Managed Instance scaling.
For more information about solutions for database scalability, please visit the below URLs: https://docs.microsoft.com/en-us/azure/azure-sql/database/scale-resources, https://docs.microsoft.com/en-us/azure/azure-sql/managed-instance/sql-managed-instance-paas-overview, https://docs.microsoft.com/en-us/azure/azure-sql/managed-instance/service-tiers-managed-instance-vcore?tabs=azure-portal
Domain : Design business continuity solutions
Q5 : A company has container-based workloads and asks you to advise how to protect the multi-region AKS deployments from regional outages.
What two services would you recommend for the company to implement?
A. Azure Backup
B. Azure VM Scale sets
C. Azure Traffic Manager
D. Azure App Service
E. Azure Load Balancer
Correct Answers: C and E
Azure provides several disaster recovery tools for container-based workloads. To protect the multi-region Azure Kubernetes Service deployments from the regional outages, you need to implement Azure Traffic Manager. Azure Traffic Manager is a global load balancing service based on DNS.
It provides high availability and disaster recovery for container-based workloads. If one region fails, Azure Traffic Manager will direct the traffic to the secondary region. Traffic Manager routes any protocol (not only HTTP/HTTPS as Azure Front Door or Azure Application Gateway does) to the service endpoint’s public IP address based on the routing method. Using geographic routing, it will direct the traffic to the closest AKS cluster and application instance. Then, the Load Balancer will take care of data delivery to the AKS.
Option A is incorrect because you need to use the Traffic Manager and Load Balancer services for multi-region AKS protection from the regional outages, but not the Azure Backup service. However, the Azure Backup service protects the application data. Your container-hosted application uses Azure Storage disks or file shares, and Azure Backup will be an appropriate data recovery service.
Option B is incorrect because you need to use the Traffic Manager and Load Balancer services for multi-region AKS protection from the regional outages, but not the Azure VM Scale sets. However, in case of node failures, Azure Kubernetes Service uses VM Scale sets to protect the nodes.
Option D is incorrect because you need to use the Traffic Manager service and Load Balancer services for multi-region AKS protection from the regional outages, but not the Azure App Service. Azure App Service is a fully managed web application hosting platform.

Which of the following would you implement for this requirement?
A. Azure Data Factory
B. Data Migration Assistant
C. Microsoft SQL Server Migration Assistant (SSMA)
D. AzCopy
Correct Answer: A
Explanation
Azure Data Factory is managed cloud service for extract-transform-load (ETL), extract-load-transform (ELT), and data integration operations. With Azure Data Factory, you can create a data pipeline. A data pipeline is a logical group of activities (steps) that perform a unit of work. Each activity consists of tasks. You can implement the data pipeline to transfer data from Azure Blob storage to an Azure SQL database. It can also run based on a schedule.
Option B is incorrect because Data Migration Assistant helps assess compatibility issues when upgrading your data store to a newer version of SQL Server or Azure SQL database.
Option C is incorrect because Microsoft SQL Server Migration Assistant (SSMA) helps automate the database migration to SQL Server from Microsoft Access, DB2, MySQL, Oracle, and SAP ASE.
Option D is incorrect because AzCopy helps to copy data between Azure storage accounts.

Q10 : Your organization has multiple Azure Cosmos DB accounts. You need to recommend what API to use for applications functionality.
Which of the following API would you use to host graph-based data?
A. SQL
B. Table
C. Gremlin
D. Cassandra
E. MongoDB
Correct Answer: C
Explanation
Azure Cosmos DB is a multi-model globally distributed NoSQL database. Cosmos DB stores data in atom-record-sequence (ARS) format. It unites under one roof several data management systems and exposes them in the form of APIs. You can select between the Core (SQL) API and MongoDB API (document model), Cassandra API (column-oriented model), Gremlin API (graph model), and Table API (key-value model). You should select the default Cosmos DB API: Core (SQL) for the new projects. If you have an existent database in formats that Cosmos DB API supports and do not want to deal with application migration, the best way is to bring the data to Cosmos DB and use provided APIs for your application. For example, suppose you have a MongoDB database with the purchase orders in different formats that are suitable for your customers. In that case, you can bring data to Cosmos DB with native MongoDB tools, like mongodump and mongorestore. And use all MongoDB queries in your apps for the data access now in Cosmos DB. But if the business logic of your application will get better data representation, for example, in a graph, you should use Gremlin API in your applications instead of the Core.
The graph model presents the data as vertex (an individual database item) and edge (a connection between items). To query the data, Gremlin API uses Apache Tinkerpop’s Gremlin language. The data model is useful for e-commerce or fraud detection when you need to track the relation between different types of information like customers, billings, delivery addresses, payments, order history, etc.

There is a requirement to ensure that an IT administrator gets an email whenever the following operations are performed on the Virtual Machine.
- Restart of the machine
- Whenever the machine is deallocated
- Whenever the machine is powered off
You need to decide on the minimum number of rules and actions groups required in Azure Monitor for this requirement. Choose two answers from the options given below.
A. Three rules
B. One rule
C. One action group
D. Three action groups
Correct Answers: A and C
Explanation
To monitor the three events in Azure Monitor, you need to create 3 separate rules for each requirement. When you open from Azure Monitor blade the Alerts screen and select the “New Alert Rule” link, the Azure portal opens the “Create alert rule” screen (Number 1). You need to fill the sections on this panel. First, you select a scope for the monitoring (Number 2): your VM, subscription, and resource group. Then, you choose the Activity Log event (signal) to trigger the alert (Number 3) under the Condition section. You can create only one alert per event (Number 4). Next, you add an Action group that will send a notification email (Number 5), provide a rule name, and create it.
After creating three alert rules, you can review them on the “Alert rules” screen.
And you can review the Action group on the “Manage actions” screen as well.
In the end, you have three rules and one action group.
All other options are incorrect.

Q12 : Your company wants to deploy a new Azure web application. The web application will use Azure blob storage for storage of static content. The Web application uses a large number of JavaScript files along with cascading style sheets. The users of the web application are located across the world. You have to ensure the time to load individual pages is minimized. Which of the following would you recommend for this requirement?
A. Make use of Azure Redis Cache
B. Make use of Azure Content Delivery Network
C. Make use of the Azure Load Balancer
D. Make use of the Azure Application Gateway
Correct Answer: B
Explanation
To distribute static web content to users across the world, you should use the Azure CDN service. Azure Content Delivery Network (CDN) service caches the web content on the edge servers and delivers it to point-of-presence (POP) locations. It uses the distributed network of the servers. The network cuts content delivery time to the end-users by serving the cached data from the closest servers instead of the origin server. CDN delivers static web content and, leveraging the POPs, accelerates the dynamic content that cannot be cached.
All other options are incorrect.

Q14 : A company wants to migrate workloads from on-premises to the cloud.
What are the three main migration effort phases that you would advise the company to prepare for?
A. Release workloads
B. Load workloads
C. Deploy workloads
D. Assess workloads
E. Test workloads
Correct Answers: A, C and D
Explanation
Migration efforts based on Azure Cloud Adoption Framework include the incremental approaches to the workloads. Each migration iteration is a batch of migration waves — the smallest workload that produces tangible results. Usually, the iteration consists of the three phases:
- Assess workloads — these workloads help to evaluate costs, architecture, and deployment tools.
- Deploy workloads — these workloads replicate the current functionality in a cloud using lift and shift, lift, and optimize approaches.
- Release workloads — these workloads provide test, optimization, documentation, and release of the cloud migration efforts.
All other options are incorrect.
