• Question 222:

  You plan to store 20 TB of data in Azure. The data will be accessed infrequently and visualized by using Microsoft Power BI.

  You need to recommend a storage solution for the data.

  Which two solutions should you recommend? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. Azure Data Lake

  You can use Power BI to analyze and visualize data stored in Azure Data Lake and Azure SQL Data Warehouse.

  Azure Data Lake includes all of the capabilities required to make it easy for developers, data scientists and analysts to store data of any size and shape and at any speed, and do all types of processing and analytics across platforms and languages. It removes the complexities of ingesting and storing all your data while making it faster to get up and running with batch, streaming and interactive analytics. It also integrates seamlessly with operational stores and data warehouses so that you can extend current data applications.

• Question 224:

  HOTSPOT

  Which cloud deployment solution is used for Azure virtual machines and Azure SQL databases?

  To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  Box 1:

  Azure virtual machines are Infrastructure as a Service (IaaS).

  Infrastructure as a Service is the most flexible category of cloud services. It aims to give you complete control over the hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems). Instead of buying hardware, with IaaS, you rent it.

  Box 2:

  Azure SQL databases are Platform as a Service (Paas).

  Azure SQL Database is a fully managed Platform as a Service (PaaS) Database Engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement. Azure SQL Database is always running on the latest stable version of SQL Server Database Engine and patched OS with 99.99% availability. PaaS capabilities that are built-in into Azure SQL database enable you to focus on the domain specific database administration and

  optimization activities that are critical for your business.

• Question 225:

  What is the function of a Site-to-Site VPN?

  A. provides a secure connection between a computer on a public network and the corporate network
  B. provides a connection from an on-premises VPN device to an Azure VPN gateway
  C. provides a dedicated private connection to Azure that does NOT travel over the internet
  B. provides a connection from an on-premises VPN device to an Azure VPN gateway

• Question 226:

  HOTSPOT

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Box: High availability

  High availability ensures access to cloud resources in the event of a service failure.

  High availability is a quality of computing infrastructure that is important for mission-critical systems. High availability permits the computing infrastructure to continue functioning, even when certain components fail.

  High availability ensures access to cloud resources in the event of a service failure.

• Question 227:

  You have a resource group named RG1.

  You plan to create virtual networks and app services in RG1.

  You need to prevent the creation of virtual machines only in RG1.

  What should you use?

  A. a lock
  B. an Azure role
  C. a tag
  D. an Azure policy
  D. an Azure policy

  ---

  Azure policies can be used to define requirements for resource properties during deployment and for already existing resources. Azure Policy controls properties such as the types or locations of resources.

  Azure Policy is a service in Azure that you use to create, assign, and manage policies. These policies enforce different rules and effects over your resources, so those resources stay compliant with your corporate standards and service level agreements.

  In this question, we would create a Azure policy assigned to the resource group that denies the creation of virtual machines in the resource group.

  You could place a read-only lock on the resource group. However, that would prevent the creation of any resources in the resource group, not virtual machines only. Therefore, an Azure Policy is a better solution.

• Question 228:

  HOTSPOT

  To complete the sentence, select the appropriate option in the answer area.

  

  

  Explanation:

  An organization that hosts its infrastructure in the public cloud no longer requires a data center.

• Question 229:

  You need to identify which Azure feature provides DDoS mitigation automatically for all public IP resources at no additional cost. What should you use?

  A. Azure Firewall
  B. Azure Front Door
  C. DDoS Protection Basic
  D. DDoS Protection Standard
  C. DDoS Protection Basic

  ---

  All Azure public IPs include DDoS Protection Basic by default at no cost. Standard is paid and provides enhanced protection. Firewall and Front Door are different security services.

• Question 230:

  DRAG DROP

  Match the Azure Cloud Services benefit to the correct description.

  Instructions: To answer, drag the appropriate benefit from the column on the left to its description on the right. Each benefit may be used once, more than once, or not at all.

  NOTE: Each correct match is worth one point.

  Select and Place:

  

  

  Explanation:

  Box 1:

  Fault tolerance is the ability of a service to remain available after a failure of one of the components of the service. For example, a service running on multiple servers can withstand the failure of one of the servers.

  Box 2:

  Disaster recovery is the recovery of a service after a failure. For example, restoring a virtual machine from backup after a virtual machine failure.

  Box 3:

  Dynamic scalability is the ability for compute resources to be added to a service when the service is under heavy load. For example, in a virtual machine scale set, additional instances of the virtual machine are added when the existing virtual machines are under heavy load.

  Box 4:

  Latency is the time a service to respond to requests. For example, the time it takes for a web page to be returned from a web server. Low latency means low response time which means a quicker response.
