Tutorial / Cram Notes
Microsoft 365 Identity and Services, designated by the exam code MS-100, is a critical certification for IT professionals who wish to validate their skills in managing and implementing Microsoft 365 services, including planning a tenant. A tenant in the context of Microsoft 365 is essentially a dedicated instance of Azure AD, Office 365, and other related services. It’s where all the user accounts, groups, subscriptions, and data reside.
When planning a tenant for your organization, there are several considerations to keep in mind:
Tenant Name and Domain
Choosing a tenant name and domain is your first step. This name is used in your organization’s SharePoint URL (https://yourtenantname.sharepoint.com) and will be part of your default onmicrosoft.com domain. The name should be unique and identifiable to your organization.
Licensing and Subscriptions
You need to understand the different Microsoft 365 licenses and what each offers. There are several license types available: Business, Enterprise, Education, and more, each with different features and services. Understanding your organization’s needs is key to choosing the right subscription.
| License Type | Target Organization Size | Include Office Apps | Advanced Security |
|---|---|---|---|
| Business Basic | Small to medium | No | Basic |
| Business Standard | Small to medium | Yes | Basic |
| E3 | Large | Yes | Advanced |
| E5 | Large | Yes | Most Advanced |
User Identity and Authentication
When planning your tenant, consider how users will be managed and authenticated. Will you use cloud-only identities, or will you synchronize accounts from an on-premise Active Directory using tools like Azure AD Connect? Also, consider if you require additional security measures such as Multi-Factor Authentication (MFA).
Data Migration and Services
If migrating from another system, plan for data migration and integration with existing on-premise services. This could involve moving email from an on-premise exchange or migrating documents from other storage solutions to SharePoint Online or OneDrive for Business.
Compliance and Security
Microsoft 365 offers various compliance and security features. Identify the necessary compliance standards for your industry (GDPR, HIPAA, etc.) and plan to use Microsoft 365’s compliance tools accordingly. Also, assess which security features like Advanced Threat Protection (ATP) or Azure Information Protection (AIP) are needed for your tenant.
Examples of Planning a Tenant
Imagine a scenario where a medium-sized business chooses Microsoft 365 Business Standard licenses for its employees to have access to Office applications and Teams for collaboration. They decide on the name “northwindtraders365” for their tenant, resulting in a domain of northwindtraders365.onmicrosoft.com. They opt to use Azure AD Connect to synchronize their on-premise Active Directory, enabling users to have single sign-on (SSO) access to Microsoft 365 services. They also turn on MFA to increase their security posture and plan to migrate their email services from an in-house Exchange server to Exchange Online.
In another example, a larger enterprise opts for the E5 license, allowing them to take advantage of advanced security features and analytics tools. They set up multiple domains to reflect their different business units but have a primary domain for consistent branding across their Microsoft 365 services. They use Microsoft’s compliance center to manage the various regulatory requirements they face, including data retention policies and eDiscovery.
In summary, planning a Microsoft 365 tenant requires careful consideration of your organization’s unique requirements. An effective plan includes proper selection of tenant name, license type, user management strategy, migration planning, and an outline of necessary security and compliance measures. Each decision will lay the groundwork for how well Microsoft 365 services integrate into your organization’s IT infrastructure and how effectively users can collaborate and be productive.
Practice Test with Explanation
True or False: When planning a Microsoft 365 tenant, considering compliance requirements is unnecessary.
- False
Compliance requirements are crucial when planning a Microsoft 365 tenant as they affect how the tenant should handle data protection, privacy, and regulatory standards.
True or False: You need to buy separate licenses for each service in Microsoft
- False
Microsoft 365 offers bundled licenses that include access to multiple services such as Office 365, Windows 10, and Enterprise Mobility + Security.
When planning a Microsoft 365 tenant, which of the following should be considered? (Select all that apply)
- a) Network infrastructure
- b) Regulatory compliance needs
- c) On-premise server hardware
- d) Email migration paths
Answer: a, b, d
Network infrastructure, regulatory compliance needs, and email migration paths are all important considerations when planning a Microsoft 365 tenant. On-premise server hardware may be relevant for hybrid configurations but is not a factor for the tenant itself.
Which of the following is responsible for managing user identities and permissions in a Microsoft 365 tenant?
- a) Microsoft Support
- b) Tenant administrator
- c) Internet service provider
- d) Microsoft account
Answer: b
The tenant administrator is responsible for managing user identities, permissions, and overall tenant configuration in a Microsoft 365 environment.
True or False: In a Microsoft 365 tenant, custom domain names can be used in place of the onmicrosoft.com domain.
- True
Custom domain names can be added to a Microsoft 365 tenant to personalize the user experience and email addresses.
True or False: License management in Microsoft 365 does not allow for mixing and matching different license types to fit user needs.
- False
License management in Microsoft 365 is flexible, and administrators can mix and match different license types depending on the needs of each user.
True or False: You can set up multiple Microsoft 365 tenants for your organization if needed.
- True
Organizations can have multiple Microsoft 365 tenants, which can be useful for large corporations, multinational organizations, or for accommodating different business units with separate needs.
When planning a Microsoft 365 tenant, which factor is NOT a part of tenant-level settings?
- a) Custom domain configuration
- b) End-user device compliance policies
- c) Organization profile settings
- d) Personal OneDrive storage space
Answer: d
Personal OneDrive storage space is not a part of tenant-level settings, as it’s configured at the user level, not the tenant level.
Which of the following services is NOT included in all Microsoft 365 enterprise plans?
- a) Exchange Online
- b) SharePoint Online
- c) Microsoft Defender for Endpoint
- d) Microsoft Teams
Answer: c
Microsoft Defender for Endpoint is not included in all Microsoft 365 enterprise plans and may require additional licensing.
True or False: As part of planning a Microsoft 365 tenant, it is important to assess the organization’s existing IT infrastructure to determine compatibility.
- True
Assessing the existing IT infrastructure is critical to ensure compatibility and to plan for potential migration and integration efforts.
True or False: Multi-factor authentication (MFA) settings are managed at the tenant level by default in Microsoft
- True
MFA settings are managed at the tenant level by default but can be configured for individual users or groups as needed.
True or False: It is possible to integrate on-premise Active Directory with a Microsoft 365 tenant using Azure AD Connect.
- True
Azure AD Connect allows organizations to integrate their on-premises Active Directory with Azure Active Directory and hence with their Microsoft 365 tenant for a seamless identity management experience.
