A company deploys Azure Active Directory (Azure AD) Connect to synchronize identity information from their on-premises Active Directory Domain Services (AD DS) directory to their Azure AD tenant The identity information that is synchronized includes user accounts, credential hashes for authentication (password sync), and group memberships. The company plans to deploy several Windows and Linux virtual machines (VMs) to support their applications. The VMs have the following requirements: * Support domain join. LDAP read. LDAP rand. NTLM and Kerberos authentication and Group Policy. * Allow users to sign in to the domain using their corporate credential and connect remotely to the VM by using Remote Desktop. You need to support the VM deployment Which service should you use?
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have an Azure Storage account that contains two 1-GB data files named File1 and File2. The data files are set to use the archive access tier. You need to ensure that File1 is accessible immediately when a retrieval request is initiated. Solution: You move File1 to a new storage account. For File1, you set Access tier to Archive. Does this meet the goal?
Correct Answer: B
Instead use the hot access tier. The hot access tier has higher storage costs than cool and archive tiers, but the lowest access costs. Example usage scenarios for the hot access tier include: * Data that's in active use or expected to be accessed (read from and written to) frequently. * Data that's staged for processing and eventual migration to the cool access tier.

Overview Contoso, Ltd, is a US-based financial services company that has a main office in New York and a branch office in San Francisco. Existing Environment. Payment Processing System Contoso hosts a business-critical payment processing system in its New York data center. The system has three tiers: a front-end web app, a middle-tier web API, and a back-end data store implemented as a Microsoft SQL Server 2014 database. All servers run Windows Server 2012 R2. The front-end and middle-tier components are hosted by using Microsoft Internet Information Services (IIS). The application code is written in C# and ASP.NET. The middle-tier API uses the Entity Framework to communicate to the SQL Server database. Maintenance of the database is performed by using SQL Server Agent jobs. The database is currently 2 TB and is not expected to grow beyond 3 TB. The payment processing system has the following compliance-related requirements: * Encrypt data in transit and at rest. Only the front-end and middle-tier components must be able to access the encryption keys that protect the data store. * Keep backups of the data in two separate physical locations that are at least 200 miles apart and can be restored for up to seven years. * Support blocking inbound and outbound traffic based on the source IP address, the destination IP address, and the port number. * Collect Windows security logs from all the middle-tier servers and retain the logs for a period of seven years. * Inspect inbound and outbound traffic from the front-end tier by using highly available network appliances. * Only allow all access to all the tiers from the internal network of Contoso. Tape backups are configured by using an on-premises deployment of Microsoft System Center Data Protection Manager (DPM), and then shipped offsite for long term storage. Existing Environment. Historical Transaction Query System Contoso recently migrated a business-critical workload to Azure. The workload contains a .NET web service for querying the historical transaction data residing in Azure Table Storage. The .NET web service is accessible from a client app that was developed in-house and runs on the client computers in the New York office. The data in the table storage is 50 GB and is not expected to increase. Existing Environment. Current Issues The Contoso IT team discovers poor performance of the historical transaction query system, as the queries frequently cause table scans. Requirements. Planned Changes Contoso plans to implement the following changes: * Migrate the payment processing system to Azure. * Migrate the historical transaction data to Azure Cosmos DB to address the performance issues. Requirements. Migration Requirements Contoso identifies the following general migration requirements: * Infrastructure services must remain available if a region or a data center fails. Failover must occur without any administrative intervention. * Whenever possible, Azure managed services must be used to minimize management overhead. * Whenever possible, costs must be minimized. Contoso identifies the following requirements for the payment processing system: * If a data center fails, ensure that the payment processing system remains available without any administrative intervention. The middle-tier and the web front end must continue to operate without any additional configurations. * Ensure that the number of compute nodes of the front-end and the middle tiers of the payment processing system can increase or decrease automatically based on CPU utilization. * Ensure that each tier of the payment processing system is subject to a Service Level Agreement (SLA) of 99.99 percent availability. * Minimize the effort required to modify the middle-tier API and the back-end tier of the payment processing system. * Payment processing system must be able to use grouping and joining tables on encrypted columns. * Generate alerts when unauthorized login attempts occur on the middle-tier virtual machines. * Ensure that the payment processing system preserves its current compliance status. * Host the middle tier of the payment processing system on a virtual machine Contoso identifies the following requirements for the historical transaction query system: * Minimize the use of on-premises infrastructure services. * Minimize the effort required to modify the .NET web service querying Azure Cosmos DB. * Minimize the frequency of table scans. * If a region fails, ensure that the historical transaction query system remains available without any administrative intervention. Requirements. Information Security Requirements The IT security team wants to ensure that identity management is performed by using Active Directory. Password hashes must be stored on-premises only. Access to all business-critical systems must rely on Active Directory credentials. Any suspicious authentication attempts must trigger a multi-factor authentication prompt automatically.
Question 3
You are planning an Azure Storage solution for sensitive dat a. The data will be accessed daily. The data set is less than 10 GB. You need to recommend a storage solution that meets the following requirements: * All the data written to storage must be retained for five years. * Once the data is written, the data can only be read. Modifications and deletion must be prevented. * After five years, the data can be deleted, but never modified. * Data access charges must be minimized What should you recommend? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Correct Answer:
Question 4
You have an Azure subscription that contains the resources shown in the following table. You need to archive the diagnostic data for VNET1 for 365 days. The solution must minimize costs. Where should you archive the data?
Correct Answer: B
Note: The workspace is the top-level resource for Azure Machine Learning, providing a centralized place to work with all the artifacts you create when you use Azure Machine Learning. Reference: https://docs.microsoft.com/en-us/azure/machine-learning/concept-workspace
Question 5
You have five .NET Core applications that run on 10 Azure virtual machines in the same subscription. You need to recommend a solution to ensure that the applications can authenticate by using the same Azure Active Directory (Azure AD) identity. The solution must meet the following requirements: * Ensure that the applications can authenticate only when running on the 10 virtual machines. * Minimize administrative effort. What should you include in the recommendation? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
