MS-102 Deploy and manage a Microsoft 365 tenant Practice Test 7 — 15 Questions

Question 1

A newly hired administrator needs to manage user accounts, licenses, and reset passwords. Which portal should they access?

Accepted Answer

Microsoft 365 admin center. The Microsoft 365 admin center (admin.microsoft.com) is the primary portal for day-to-day user administration tasks such as creating and managing user accounts, assigning licenses, and resetting passwords. It provides a unified interface for these common identity and license management operations within a Microsoft 365 tenant.

Answer

Microsoft Entra admin center

Answer

Microsoft 365 Defender

Answer

Azure Active Directory admin center

Question 2

An administrator has created a new user account in Microsoft Entra ID. To ensure the user has a mailbox in Exchange Online, what is the next step?

Accepted Answer

Assign an Exchange Online license to the user. In Microsoft 365, a user must be assigned an Exchange Online license (part of an E3, E5, or standalone plan) before a mailbox is automatically provisioned in Exchange Online. Without a license, the user object exists in Entra ID but has no mailbox; the license assignment triggers the mailbox creation process within 24 hours.

Answer

Create an Exchange mailbox manually

Answer

Run the Microsoft 365 Setup wizard

Answer

Configure DNS records for the domain

Question 3

An organization has registered the domain contoso.com and added it to their Microsoft 365 tenant. What is the next step to use this domain for user email addresses?

Accepted Answer

Add a DNS TXT record provided by Microsoft to the domain registrar. After adding a custom domain to Microsoft 365, the domain's ownership must be verified by adding a specific DNS TXT record provided by Microsoft at the domain registrar. This verification proves you control the domain and is a prerequisite before you can assign user email addresses or configure other DNS records like MX. Without this step, Microsoft 365 will not trust the domain for email routing.

Answer

Create user accounts with the new domain

Answer

Configure Exchange Online connectors

Answer

Set up MX records for email routing

Question 4

A company has recently signed up for Microsoft 365 Business Premium. They want to change the default domain from onmicrosoft.com to a custom domain they own. Which step must be completed first before the custom domain can be used for user email addresses?

Accepted Answer

Add the custom domain in the Microsoft 365 admin center. Before a custom domain can be used for user email addresses in Microsoft 365, the domain must first be added to the tenant in the Microsoft 365 admin center. This step creates a domain object in Microsoft Entra ID that allows Microsoft to associate the domain with your tenant and prepare for ownership verification. Without adding the domain first, subsequent steps like DNS verification or user creation cannot proceed because the system has no record of the domain.

Answer

Verify domain ownership by adding a TXT record to the domain's DNS

Answer

Create user accounts with the new domain as their primary email

Answer

Configure email exchange records (MX)

Question 5

An organization has just purchased Microsoft 365 subscriptions and wants to add their custom domain 'fabrikam.com' to the tenant. Which record must they add to their DNS provider to verify domain ownership?

Accepted Answer

TXT record. To verify domain ownership in Microsoft 365, you must add a TXT record provided by the Microsoft 365 admin center to your DNS hosting provider. This TXT record contains a unique verification string that Microsoft checks to confirm you control the domain. MX, CNAME, and SRV records are used for mail routing, service aliasing, and service location, respectively, but they do not serve the purpose of domain ownership verification.

Answer

MX record

Answer

CNAME record

Answer

SRV record

Question 6

A company plans to migrate their email from an on-premises Exchange server to Exchange Online. They want to ensure that during the migration, mail sent to users who have already been migrated is delivered to Exchange Online, while mail for non-migrated users is delivered to on-premises. Which type of domain configuration should they use?

Accepted Answer

Split domain. A split domain configuration is required when some mailboxes reside on-premises and others in Exchange Online during a migration. It uses MX records pointing to Exchange Online Protection (EOP) and internal mail flow connectors to route messages for migrated users to Exchange Online and non-migrated users to on-premises, ensuring each mailbox receives mail at its current location.

Answer

Coexistence domain

Answer

Shared domain

Answer

Forwarding domain

Question 7

An organization has just purchased Microsoft 365 Business Standard licenses. The administrator adds a new user through the admin center. By default, does the new user receive a welcome email with sign-in instructions?

Accepted Answer

Yes, if the administrator does not clear the 'Send welcome email' checkbox during user creation.. When an administrator adds a new user through the Microsoft 365 admin center, the default behavior is to send a welcome email containing the user's sign-in name and temporary password. The administrator can opt out by clearing the 'Send welcome email in email' checkbox during the creation process. Therefore, the user receives the email unless the administrator explicitly deselects that option.

Answer

Yes, always, regardless of how the user is created.

Answer

No, the administrator must manually send the welcome email using a script.

Answer

No, welcome emails are only sent when using the 'Add multiple users' option.

Question 8

A company has purchased Microsoft 365 Business Standard and added the custom domain 'fabrikam.com' to the tenant. The company wants all new users to have 'fabrikam.com' as their default email domain instead of the onmicrosoft.com domain. How should the administrator achieve this?

Accepted Answer

In the admin center, go to Settings > Domains, select the custom domain, and click 'Set as default'.. The Microsoft 365 admin center provides a dedicated setting under Settings > Domains to mark a custom domain as the default email domain. Once set as default, all new users will automatically receive a primary email address using that domain instead of the initial onmicrosoft.com domain, without requiring manual changes or additional configuration.

Answer

Update the MX record in the DNS to point to Microsoft 365 with the custom domain.

Answer

Use the Exchange admin center to set the default email address policy to use the custom domain.

Answer

For each new user, manually add an email alias with the custom domain and remove the onmicrosoft.com alias.

Question 9

An organization has just purchased Microsoft 365 Business Standard licenses and has added the custom domain 'contoso.com' to the tenant. The administrator wants all new user email addresses to use '@contoso.com' instead of the default '@contoso.onmicrosoft.com'. How can this be achieved?

Accepted Answer

Set the default domain in the Microsoft 365 admin center to contoso.com. Setting the default domain to 'contoso.com' in the Microsoft 365 admin center ensures that all newly created users automatically receive an email address with the custom domain as their primary SMTP address. This is the standard method because the default domain setting controls the domain appended to new user accounts during creation, eliminating the need for manual changes.

Answer

Change the primary SMTP address for each user manually after creation

Answer

Remove the onmicrosoft.com domain from the tenant

Answer

Edit the user creation PowerShell script to specify the domain

Question 10

A company has purchased Microsoft 365 Business Premium and added a custom domain 'contoso.com' to the tenant. They want all new users to have email addresses like user@contoso.com instead of the default onmicrosoft.com domain. What should the administrator do in the Microsoft 365 admin center?

Accepted Answer

Set the custom domain as the default domain in the Domains settings.. Setting the custom domain as the default domain in the Domains settings ensures that any new user created in the Microsoft 365 admin center automatically receives an email address ending with @contoso.com instead of the default @<tenant>.onmicrosoft.com. This is the correct administrative action because the default domain setting controls the domain suffix applied to new user principal names (UPNs) and email addresses during user creation.

Answer

Add a DNS TXT record for the custom domain.

Answer

Change the primary domain in the tenant's organization profile.

Answer

Update the MX record for the custom domain to point to Exchange Online.

Question 11

An organization has just signed up for Microsoft 365 E3 with the initial domain 'contoso.onmicrosoft.com'. They need to create the first user accounts. What will be the default email address format for these new users if no custom domain is added yet?

Accepted Answer

user@contoso.onmicrosoft.com. When a new Microsoft 365 tenant is created with the initial domain 'contoso.onmicrosoft.com' and no custom domain has been added, the default email address format for new users is user@contoso.onmicrosoft.com. This is because the onmicrosoft.com domain is the default tenant domain provisioned by Microsoft Entra ID, and all user principal names (UPNs) and email addresses are automatically assigned this suffix until a custom domain is verified and set as the primary domain.

Answer

user@contoso.com

Answer

user@microsoft.com

Answer

user@contoso.microsoft.com

Question 12

A company has just purchased Microsoft 365 Business Standard and added the custom domain 'fabrikam.com' to the tenant. They want to verify domain ownership. Which DNS record type must they add to their DNS provider?

Accepted Answer

TXT record. To verify domain ownership in Microsoft 365, you must add a TXT record containing a unique verification string provided by the Microsoft 365 admin center. The TXT record is the standard DNS record type used for domain validation because it can store arbitrary text data without affecting email routing or other services. Microsoft 365 checks for this specific TXT record to confirm you control the domain.

Answer

MX record

Answer

CNAME record

Answer

SPF record

Question 13

A company wants to display a custom help desk phone number and email on the Microsoft 365 sign-in page so that users can contact support easily. Which area of the Microsoft 365 admin center should the administrator use to configure this?

Accepted Answer

Settings > Org settings > Organization profile. The custom help desk contact information (phone number and email) for the Microsoft 365 sign-in page is configured under Settings > Org settings > Organization profile, specifically in the 'Custom branding' section. This setting allows administrators to add custom support contact details that appear on the sign-in page, enhancing user self-service and support accessibility.

Answer

Settings > Org settings > Security & privacy

Answer

Billing > Licenses

Answer

Health > Service Health

Question 14

An administrator wants to add custom branding to the Microsoft 365 sign-in page, including company logo and colors. Which section of the Microsoft 365 admin center should they navigate to?

Accepted Answer

Settings > Org settings > Organization profile. The custom branding for the Microsoft 365 sign-in page, including company logo and colors, is configured under Settings > Org settings > Organization profile in the Microsoft 365 admin center. This section provides a dedicated 'Custom branding' tab where administrators can upload a logo, set a background image, and choose accent colors that are applied to the sign-in page for all users in the tenant.

Answer

Users > Active users

Answer

Admin centers > Azure Active Directory

Answer

Billing > Licenses

Question 15

A company purchases Microsoft 365 E5 licenses for 500 users. The administrator wants to automatically assign licenses to new users based on their group membership. Which method should the administrator use?

Accepted Answer

Configure group-based licensing in Microsoft Entra ID. Group-based licensing in Microsoft Entra ID (formerly Azure AD) allows automatic assignment and removal of licenses based on group membership. When a user is added to a licensed group, the license is automatically assigned; when removed, the license is revoked. This eliminates manual effort and ensures consistent licensing for all 500 users.

Answer

Run a PowerShell script to assign licenses individually

Answer

Manually assign licenses in the Microsoft 365 admin center for each user

Answer

Use a volume licensing product key to activate licenses
