Contoso, Ltd. is a global manufacturing company with headquarters in Dallas. All sales users are located at the
headquarters. Currently all Contoso, Ltd. users use the following on-premises services:
Microsoft Exchange Server 2016
Microsoft Skype for Business Server 2015
Active Directory Domain Services (AD DS) domain for contoso.com
Many temporary workers are hired and terminated on a regular basis at the Dallas location, Contoso, Ltd.
purchases two other manufacturing companies, Fabrikam, Inc. and A. Datum Corporation. Fabrikam, Inc. is
based in London. Fabrikam, Inc. has an on-premises third-party email system that uses @fabrikam.com for all
email addresses. Fabrikam, Inc. does not have an Active Directory domain.
ADatum Corporation is based in Paris. The company is in the process of migrating users to Exchange Online.
They plan to migrate users to Microsoft OneDrive for Business for file storage and sharing. All A. Datum
Corporation account identities will be cloud based.
You deploy Microsoft Office 2016 client apps to all corporate devices.
In preparation for the deployment of Office 365 services, you set up the latest version of Azure Active Directory
(Azure AD) Connect for the contoso.com domain. The application runs on Server1.contoso.com and uses a
Microsoft SQL Server database instance that runs on Server2.contoso.com. The sync schedule is configured to
synchronize every two hours.
You purchase the following four servers for future needs: Server3, Server4, Server5, and Server6. All new
servers for the contoso.com domain must run Windows Server 2012 R2.
Business Requirements
Contoso, Ltd. users must be able to store and share personal documents that are accessible from any web
browser or mobile device. Fabrikam, Inc. users must be able to send individual instant messages as well as
use group chat workspaces.
Office 365
New services should be implemented in Office 365 when possible. There is also a strong push to move existing
services to Office 365, but there is currently no money in the budget for data migration. The least expensive
Office 365 plan must be used whenever possible.
Password policies
You must implement the following password policies for ADatum Corporation users.

Contoso Sync
You receive reports that new users are not granted access to Office 365 resources fast enough. You must
ensure that new accounts are provisioned as quickly as possible.
You observe that the accounts for many temporary workers have not been deprovisioned correctly. You need to
ensure terminated users have their access and accounts removed. You must ensure that up to 1,000 accounts
can be deleted correctly during each Azure AD Connect sync cycle. You must ensure that deletions of over
1,000 accounts at a time cannot occur.Single Sign-On
Contoso.com users need to start using sign-on (SSO) for Office 365 resources so they can authenticate against
the on-premises Active Directory. Any solution needs to be redundant. Any Internet-facing servers need to
reside in the perimeter network.
Problem Statements
Authentication Fallback
Sales users report that they were not able to access any Office 365 resources. Contoso.com users must be
able to access Office 365 resources if the on-premises authentication resources are down or unavailable. You
also need to quickly resume SSO authentication when on-premises servers are available again.
ADatum Corporation users report issues sending and receiving emails. Some business partners report that
emails from ADatum Corporation are rejected because the receiving server cannot validate that emails come
from an authorized messaging server.
You need to create a DNS record to resolve the email issues for A. Datum Corporation users.
How should you configure the DNS record? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
