• Question 341:

  DRAG DROP

  Match the cloud model to the correct advantage.

  Instructions: To answer, drag the appropriate cloud model from the column on the left to its advantage on the right. Each cloud model 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: Public Cloud

  With a public cloud, there is no capital expenditure on server hardware etc. You only pay for cloud resources that you use as you use them.

  Box 2: Private Cloud

  A private cloud exists on premises, so you have complete control over security.

  Box 3: Hybrid Cloud

  A hybrid cloud is a mix of public cloud resources and on-premises resources. Therefore, you have a choice to use either.

• Question 342:

  Your company plans to deploy several million sensors that will upload data to Azure.

  You need to identify which Azure resources must be created to support the planned solution.

  Which two Azure resources should you identify? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Azure Data Lake
  B. Azure Queue storage
  C. Azure File Storage
  D. Azure IoT Hub
  E. Azure Notification Hubs
  A. Azure Data Lake
  D. Azure IoT Hub

  ---

  IoT Hub (Internet of things Hub) provides data from millions of sensors. IoT Hub is a managed service, hosted in the cloud, that acts as a central message hub for bi-directional communication between your IoT application and the devices it manages. You can use Azure IoT Hub to build IoT solutions with reliable and secure communications between millions of IoT devices and a cloud- hosted solution backend. You can connect virtually any device to IoT Hub.

  There are two storage services IoT Hub can route messages to -- Azure Blob Storage and Azure Data Lake Storage Gen2 (ADLS Gen2) accounts. Azure Data Lake Storage accounts are hierarchical namespace-enabled storage accounts built on top of blob storage. Both of these use blobs for their storage.

• Question 344:

  This question requires that you evaluate the BOLD text to determine if it is correct.

  The Azure Standard support plan is the lowest cost option to receive 24x7 access to support engineers by phone.

  A. No change is needed
  B. Developer
  C. Basic
  D. Professional Direct
  A. No change is needed

  ---

  The Basic support plan is free so is therefore the cheapest. The Developer support plan is the cheapest paid-for support plan. The order of support plans in terms of cost ranging from the cheapest to most expensive is: Basic, Developer, Standard, Professional Direct, Premier.

  However, 24/7 access to technical support by email and phone is only available for Standard, Professional Direct, Premier plans.

• Question 346:

  You need to collect and automatically analyze security events from Azure Active Directory(Azure AD). What should you use?

  A. Azure Sentinel
  B. Azure Synapse Analytics
  C. Azure ADConnect
  D. Azure Key Vault
  A. Azure Sentinel

  ---

  Why the other answers are wrong:

  Azure Synapse Analytics:

  Used for data analytics and big data processing.

  It is not a security monitoring tool.

  Azure AD Connect:

  Used for synchronizing identities between on-premises Active Directory

  and Azure AD. It does not analyze security events.

  Azure Key Vault:

  Used to store secrets and encryption keys.

  It does not analyze logs or security events.

• Question 347:

  HOTSPOT

  Autoscaling is an example of: _______________

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  An Azure virtual machine scale set can automatically increase or decrease the number of VM instances that run your application. This automated and elastic behavior reduces the management overhead to monitor and optimize the performance of your application.

  Also: Azure elasticity as a service is referred to a cloud service that enables in automatically scaling Azure hosted resources in par with the demand and configured parameters. It provides Azure Administrators with the ability to auto scale Azure infrastructure and resources as and when needed.

• Question 348:

  Which Azure service is an example of serverless computing?

  A. Azure dedicated hosts
  B. Azure Virtual Machines
  C. Azure Functions
  D. Azure storage account
  C. Azure Functions

  ---

  Azure Functions is a serverless compute service that allows you to run small pieces of code (functions) without managing servers. You are billed only for the compute resources consumed while the code runs.

  Serverless computing automatically scales based on demand and abstracts infrastructure management from the user.

  Reasons why other options are incorrect: Azure Dedicated Hosts: Provides dedicated physical servers in Azure; not serverless.

  Azure Virtual Machines: Requires managing virtual machines and scaling; not serverless.

  Azure Storage Account: Provides storage services, not compute; does not execute code like serverless functions.

  A. Azure Monitor
  B. Azure Activity Log
  C. Azure Advisor
  D. Azure Cost Management
  A. Azure Monitor
