Question No. 1

Your network contains two on-premises Active Directory forests named contoso.com and fabrikam.com. Fabrikam.com contains one domain and five domain controllers. Contoso.com contains the domains shown in the following table.

You need to sync all the users from both the forests to a single Azure Active Directory (Azure AD) tenant by using Azure AD Connect.

What is the minimum number of Azure AD Connect sync servers required?

Show Answer Hide Answer
Correct Answer: A

You can have only one active Azure AD Connect server synchronizing accounts to a single Azure Active Directory (Azure AD) tenant. You can have 'backup' Azure AD Connect servers, but these must be running in 'staging' mode. Staging mode means the Azure AD Connect instance is not actively synchronizing users but is ready to be bought online if the active Azure AD Connect instance goes offline.

When you have multiple forests, all forests must be reachable by a single Azure AD Connect sync server. The server must be joined to a domain. If necessary, to reach all forests, you can place the server in a perimeter network (also known as DMZ, demilitarized zone, and screened subnet).

Correct Answer: C

When you configure conditions for a label, you can automatically assign a label to a document or email. In this case, we would create a label to label all email messages that contain the word ProjectX. We would then create a label policy to preserve a copy of all message that have the label assigned.

Please wait while the virtual machine loads. Once loaded, you may proceed to the lab section. This may take a few minutes, and the wait time will not be deducted from your overall test time.

When the Next button is available, click it to access the lab section. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design.

Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.

Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.

Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.

You may now click next to proceed to the lab.
