Microsoft - MS-203: Microsoft 365 Messaging

Sample Questions

Question: 278
Measured Skill: Secure the messaging environment (20-25%)

You have a Microsoft Exchange Online tenant that contains a user named User1.

You need to grant User1 the Send on Behalf permission for 20 mailboxes.

Which PowerShell cmdlet should you use?

AAdd-MailboxPermission
B Add-MailboxFolderPermission
C Set-Mailbox
D Add-RecipientPermission

Correct answer: C

Explanation:

In Exchange Server, you can use the Exchange admin center (EAC) or the Exchange Management Shell to assign permissions to a mailbox or group so that other users can access the mailbox (the Full Access permission), or send email messages that appear to come from the mailbox or group (the Send As or Send on Behalf permissions). The users that are assigned these permissions on other mailboxes or groups are called delegates.

Send on Behalf allows the delegate to send messages from the mailbox or group. The From address of these messages clearly shows that the message was sent by the delegate (" <Delegate> on behalf of <MailboxOrGroup>"). However, replies to these messages are sent to the mailbox or group, not to the delegate.

You use the GrantSendOnBehalfTo parameter on the various mailbox and group Set- cmdlets to manage the Send on Behalf permission for mailboxes and groups:

  • Set-Mailbox

  • Set-DistributionGroup: Distribution groups and mail-enabled security groups.

  • Set-DynamicDistributionGroup

The basic syntax for these cmdlets is:

<Cmdlet> -Identity <MailboxOrGroupIdentity> -GrantSendOnBehalfTo <Delegates>

Reference: Use the Exchange Management Shell to assign the Send on Behalf permission to mailboxes and groups



Question: 279
Measured Skill: Plan and manage the mail transport architecture (20-25%)

You have a Microsoft Exchange Online tenant that uses a third-party email hygiene system named Service1. Service1 blocks all encrypted email.

All external email is routed through Service1 by using a connector.

Users classify email by using sensitivity labels. Emails classified as Secret are encrypted automatically.

You need to ensure that the users can send emails classified as Secret to external recipients.

Which two items should you create?

(Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.)

AA remote domain
B A connector
C A data loss prevention (DLP) policy
D A mail flow rule
E A label policy

Correct answer: B, D

Explanation:

As the first stept, we should create a new send connector that sends email messages directly to the internet to bypass the third-party email hygiene system.

As the second step, we should create a mail flow rule that applies to messages classified as Secret and redirects the messages to the new connector.

Correct answer: C

Explanation:

Malware filter policies contain the malware settings and a list of domains to which those settings apply. A domain can't belong to more than one malware filter policy.

The Action parameter specifies the action to take when malware is detected in a message. Valid values are:

  • DeleteMessage: Handles the message without notifying the recipients. This is the default value. In Exchange Server, the message is deleted. In the cloud-based service, the message is quarantined.
  • DeleteAttachmentAndUseDefaultAlert: Delivers the message, but replaces all attachments with a file named Malware Alert Text.txt that contains the default alert text. In the cloud-based service, the message with the original attachments is also quarantined.
  • DeleteAttachmentAndUseCustomAlert: Delivers the message, but replaces all attachments with a file named Malware Alert Text.txt that contains the custom alert text specified by the CustomAlertText parameter. In the cloud-based service, the message with the original attachments is also quarantined.

The BypassInboundMessages parameter enables or disables malware filtering on incoming messages (messages entering the organization). Valid values are:

  • $true: Malware filtering is disabled on inbound messages.
  • $false: Malware filtering is enabled on inbound messages. This is the default value.

The Priority parameter of a transport agent specifies the priority of the transport agent. The priority of the transport agent controls the order in which the transport agents process email messages. The priority must be a value between 0 and the maximum number of transport agents. The default behavior is to append a new transport agent to the end of the priority list. Transport agents with a priority closest to 0 process email messages first.

Note that the malware agent is disabled. To ensure that incoming messages are scanned for malware, the agent must be activated.

Question: 281
Measured Skill: Plan and implement a hybrid configuration and migration (20-25%)

You have a hybrid deployment between a Microsoft Exchange Online tenant and an on-premises Exchange Server 2013 organization.

The deployment contains the public folders shown in following table.



You need to configure the deployment to meet the following requirements:
  • Exchange Server 2013 mailbox users must be able to access PF2.
  • Exchange Online mailbox users must be able to access PF1.
Which PowerShell script should you run from an Exchange Server 2013 server to meet each requirement?

(To answer, drag the appropriate scripts to the correct requirements. Each script may be used once, more than once, or at all. NOTE: Each correct selection is worth one point.)

www.cert2brain.com

AEnable Exchange Server 2013 mailbox users to access PF2: Sync-MailPublicFoldersCloudToOnprem-ps1 , Import-PublicFolderMailboxes.ps1
Enable Exchange Online mailbox users to access PF1: Sync-ModernMailPublicFolders.ps1
B Enable Exchange Server 2013 mailbox users to access PF2: Sync-MailPublicFolders.ps1 , Sync-ModernMailPublicFolders.ps1
Enable Exchange Online mailbox users to access PF1: Import-PublicFolderMailboxes.ps1
C Enable Exchange Server 2013 mailbox users to access PF2: Sync-MailPublicFoldersCloudToOnprem-ps1 , Sync-MailPublicFolders.ps1
Enable Exchange Online mailbox users to access PF1: Sync-ModernMailPublicFolders.ps1
D Enable Exchange Server 2013 mailbox users to access PF2: Sync-ModernMailPublicFolders.ps1, Import-PublicFolderMailboxes.ps1
Enable Exchange Online mailbox users to access PF1: Sync-MailPublicFoldersCloudToOnprem-ps1

Correct answer: A

Explanation:

To enable on-premises mailbox users to access cloud-based public folders, first we have to run the following command to synchronize mail-enabled public folders from Exchange Online, Microsoft 365, or Office 365 to our local on-premises Active Directory.

Sync-MailPublicFoldersCloudToOnprem.ps1 -Credential (Get-Credential)

Second, we have to run the following command to import public folder mailbox objects from the cloud to our on-premises Active Directory. The script will also configure the imported objects as remote public folder mailboxes.

Import-PublicFolderMailboxes.ps1 -Credential (Get-Credential)

Third, we have to enable the Exchange 2013 on-premises organization to access the Exchange Online public folders by running the following cmdlet.

Set-OrganizationConfig -PublicFoldersEnabled Remote

To enable cloud-based mailbox users to access on-premises public folders, we have to synchronize mail-enabled public folders from our local on-premises Active Directory to Office 365 by running the following script.

.\Sync-ModernMailPublicFolders.ps1 -CsvSummaryFile:sync_summary.csv

Where CsvSummaryFile is the path to where you would like to log synchronization operations and errors, in .csv format.

Question: 282
Measured Skill: Manage organizational settings and resources (30-35%)

You have a Microsoft Exchange Online tenant.

Users report that they cannot view attachments from Outlook on the web from their home computer.

The Outlook Web App policy has the following settings.



You need to ensure that the users can view attachments when they access Outlook on the web from their home computer.

How should you complete the command?

(To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.)

www.cert2brain.com

ASet-OWAMailboxPolicy -Identity OwaMailboxPolicy-Default -ActionForUnknownFileAndMIMETypes Allow
B Set-OWAMailboxPolicy -Identity OwaMailboxPolicy-Default -ConditionalAccessPolicy False
C Set-OWAMailboxPolicy -Identity OwaMailboxPolicy-Default -ForceWebReadyDocumentViewingFirstOnPublicComputer True
D Set-OWAMailboxPolicy -Identity OwaMailboxPolicy-Default -MessagePreviewsDisabled ReadOnly
E Set-OWAMailboxPolicy -Identity OwaMailboxPolicy-Default -MessagePreviewsDisabled ForceSave
F Set-OWAMailboxPolicy -Identity OwaMailboxPolicy-Default -OWALightEnabled True

Correct answer: A

Explanation:

In Exchange Online, Outlook on the web mailbox policies control the availability of settings and features in Outlook on the web (formerly known as Outlook Web App). A mailbox can only have one Outlook on the web mailbox policy applied to it. You can create different policies for different types of users in your Exchange Online organization.

Every Exchange Online organization has a default Outlook on the web mailbox policy named OwaMailboxPolicy-Default that's applied to all user mailboxes.

We have to set the ActionForUnknownFileAndMIMETypes parameter to the default value Allow. The ActionForUnknownFileAndMIMETypes parameter specifies how to handle file types that aren't specified in the Allow, Block, and Force Save lists for file types and MIME types. Valid values are:

  • Allow (This is the default value.)
  • ForceSave
  • Block

Note: The ForceWacViewingFirstOnPrivateComputers parameter specifies whether private computers must first preview an Office file as a web page in Office Online Server (formerly known as Office Web Apps Server and Web Access Companion Server) before opening the file in the local application. The parameter is only valid in Exchange Server.
