MS-102 Deploy and manage a Microsoft 365 tenant Practice Test 2 — 15 Questions

Question 1

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'.. Option B is correct because 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 2

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 3

An administrator needs to delegate the ability to manage user licenses, assign admin roles, and reset passwords to a group of users, but these users should not be able to modify tenant-level settings or billing. Which built-in role should be assigned?

Accepted Answer

User Administrator. The User Administrator role is the correct choice because it grants the necessary permissions to manage user licenses, assign admin roles (except for a few high-privilege roles like Global Administrator), and reset passwords, while explicitly excluding access to tenant-level settings and billing. This role is designed for delegated user management without granting broader administrative control.

Answer

Global Administrator

Answer

Helpdesk Administrator

Answer

License Administrator

Question 4

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 5

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 Azure AD, 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 6

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 7

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. Option B is correct because 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 8

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 9

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

Question 10

A company adds and verifies the custom domain 'contoso.com' in their Microsoft 365 tenant. However, emails sent to new users at user@contoso.com bounce back. The existing MX record for contoso.com points to the on-premises mail server. What is the most likely cause of the bounce?

Accepted Answer

The MX record must be updated to point to Exchange Online. B is correct because the MX record for contoso.com still points to the on-premises mail server. When a user is created in Exchange Online with the domain contoso.com, inbound email is routed according to the MX record. Since the MX record directs mail to the on-premises server, which does not have a mailbox for the new user, the message bounces. To deliver mail to Exchange Online, the MX record must be updated to point to Exchange Online (e.g., contoso-com.mail.protection.outlook.com).

Answer

The domain verification failed and needs to be repeated

Answer

Users must be added to the domain in the admin center

Answer

The SPF record is missing or misconfigured

Question 11

An administrator needs to delegate the ability to view service health and manage service requests to a helpdesk team, without granting permissions to reset passwords, manage users, or access billing. Which built-in Microsoft 365 admin role should be assigned?

Accepted Answer

Service Support Administrator. The Service Support Administrator role is the correct built-in role because it grants the specific permissions needed to view service health and manage service requests in the Microsoft 365 admin center, while explicitly excluding permissions to reset passwords, manage users, or access billing. This role is designed for helpdesk teams that need to handle service incidents without broader administrative access.

Answer

Helpdesk Administrator

Answer

Service Administrator

Answer

Security Reader

Question 12

An administrator needs to open a Microsoft 365 support request because a critical service issue is affecting all users. Which two pieces of information should the administrator have readily available before contacting support? (Choose two.)

Accepted Answer

Tenant ID. The Tenant ID (A) is a unique, immutable identifier for the Microsoft 365 tenant, required by Microsoft Support to locate the tenant in their systems and verify administrative access. The current service health status (C) is critical because the support engineer will first check the Microsoft 365 Service Health Dashboard (admin.microsoft.com/Adminportal/Home?source=applauncher#/servicehealth) to confirm the issue is a known service incident; having this information ready avoids redundant troubleshooting and speeds up the creation of a service request.

Answer

User principal names of affected users

Answer

Billing contact information

Question 13

A company has just signed up for Microsoft 365 Business Standard without adding a custom domain. An administrator needs to create the first user accounts. What will be the default email address format for these new users?

Accepted Answer

username@.onmicrosoft.com. When a Microsoft 365 tenant is created without adding a custom domain, the default domain is the `.onmicrosoft.com` domain. New user accounts are automatically assigned an email address in the format `username@.onmicrosoft.com`, as this is the initial domain provisioned for the tenant. Option C correctly reflects this default behavior.

Answer

username@contoso.com

Answer

username@onmicrosoft.com

Answer

username@microsoftonline.com

Question 14

After adding a custom domain name to a Microsoft 365 tenant, what is the first step the administrator must complete before users can sign in using the custom domain?

Accepted Answer

Verify domain ownership by adding a DNS TXT record. Before a custom domain can be used for user sign-ins or email routing in Microsoft 365, the administrator must prove ownership of the domain. This is done by adding a specific DNS TXT record provided by the Microsoft 365 domain setup wizard. Until the TXT record is verified, the domain remains unverified and cannot be used for any Microsoft 365 services.

Answer

Add the domain as an accepted domain in Exchange Online

Answer

Set the custom domain as the default domain for new users

Answer

Create user accounts with usernames ending with the custom domain

Question 15

An administrator needs to delegate the ability to view sign-in logs, audit logs, and security recommendations to a junior admin without granting any other administrative permissions. The junior admin should not be able to reset passwords or modify settings. Which built-in Microsoft Entra role should the administrator assign?

Accepted Answer

Security Reader. The Security Reader role in Microsoft Entra ID is specifically designed to grant read-only access to security-related data, including sign-in logs, audit logs, and security recommendations, without allowing any write operations such as password resets or configuration changes. This makes it the correct choice for delegating visibility into security monitoring without administrative control.

Answer

Global Reader

Answer

Reports Reader
