• Question 192:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  Box 1: Yes

  In azure active directory premium, at least 99.9 percent availability is guaranteed.

  Microsoft guarantee at least 99.9% availability of the Azure Active Directory Basic and Premium services. The services are considered available in the following scenarios:

  1. Users are able to login to the service, login to the Access Panel, access applications on the Access Panel and reset passwords.

  2. IT administrators are able to create, read, write and delete entries in the directory or provision or de-provision users to applications in the directory.

  Box 2: No

  No SLA is provided for the Free tier of Azure Active Directory.

  Box 3: Yes

  You can claim credit if the availability falls below the SLA. The amount of credit depends on the availability. For example: You can claim 25% credit if the availability is less than 99.9%, 50% credit for less than 99% and 100% for less than 95% availability.

  Physically separate locations across two continents: Incorrect; zones exist only within a single region.

  Within multiple Azure regions:

  Incorrect; multiple regions are handled by paired regions, not zones.

  Within a single Azure datacenter:

  Incorrect; a zone can consist of a full datacenter or group of datacenters, not just a single datacenter.

  Explanation:

  Box 1:

  Azure AI bot provides a digital online assistant that provides speech support.

  Bots provide an experience that feels less like using a computer and more like dealing with a person or at least an intelligent robot. They can be used to shift simple, repetitive tasks, such as taking a dinner reservation or gathering profile information, on to automated systems that may no longer require direct human intervention. Users converse with a bot using text, interactive cards, and speech. A bot interaction can be a quick question and answer, or it can be a sophisticated conversation that intelligently

  provides access to services.

  Box 2:

  Azure Machine Learning uses past trainings to provide predictions that have high probability.

  Machine learning is a data science technique that allows computers to use existing data to forecast future behaviors, outcomes, and trends. By using machine learning, computers learn without being explicitly programmed.

  Forecasts or predictions from machine learning can make apps and devices smarter. For example, when you shop online, machine learning helps recommend other products you might want based on what you've bought.

  Box 3:

  Azure Functions provides serverless computing functionalities.

  Azure Functions is a serverless compute service that lets you run event-triggered code without having to explicitly provision or manage infrastructure.

  Box 4:

  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.

• Question 200:

  HOTSPOT

  You plan to deploy a critical line-of-business application to Azure.

  The application will run on an Azure virtual machine.

  You need to recommend a deployment solution for the application. The solution must provide a guaranteed availability of 99.99 percent.

  What is the minimum number of virtual machines and the minimum number of availability zones you should recommend for the deployment? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  You need a minimum of two virtual machines with each one located in a different availability zone. Minimum number of virtual machines: 2 Availability Zones is a high-availability offering that protects your applications and data from datacenter failures. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there's a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures. Zone-

  redundant services replicate your applications and data across Availability Zones to protect from single-points-of-failure. With Availability Zones, Azure offers industry best 99.99% VM uptime SLA.
