Microsoft Security Administration(MS-500) Case Study-2

Overview

Litware, Inc. is a financial company that has 1,000 users in its main office in Chicago and 100 users in a branch office in San Francisco.

Existing Environment

Internal Network Infrastructure

The network contains a single domain forest. The forest functional level is Windows Server 2016.
Users are subject to sign-in hour restrictions as defined in Active Directory.
The network has the IP address ranges shown in the following table:

The offices connect by using Multiprotocol Label Switching (MPLS).
The following operating systems are used on the network:
Windows Server 2016
Windows 10 Enterprise
Windows 8.1 Enterprise
The internal network contains the systems shown in the following table:

Litware uses a third-party email system.

Cloud Infrastructure

Litware recently purchased Microsoft 365 subscription licenses for all users.
Microsoft Azure Active Directory (Azure AD) Connect is installed and uses the default authentication
settings. User accounts are not yet synced to Azure AD.
You have the Microsoft 365 users and groups shown in the following table.

Requirements

Planned Changes

Litware plans to implement the following changes:
Migrate the email system to Microsoft Exchange Online
Implement Azure AD Privileged Identity Management

Security Requirements

Litware identifies the following security requirements:

Create a group named Group3 that will be used for publishing sensitivity labels to pilot users. Group3
must only contain user accounts
Use Azure Advanced Threat Protection (ATP) to detect any security threats that target the forest
Prevent users locked out of Active Directory from signing in to Azure AD and Active Directory
Implement a permanent eligible assignment of the Compliance administrator role for User1
Configure domain-joined servers to ensure that they report sensor data to Microsoft Defender ATP
Prevent access to Azure resources for the guest user accounts by default
Ensure that all domain-joined computers are registered to Azure AD
Multi-factor authentication (MFA) Requirements
Security features of Microsoft Office 365 and Azure will be tested by using pilot Azure user accounts.
You identify the following requirements for testing MFA:
Pilot users must use MFA unless they are signing in from the internal network of the Chicago office.
MFA must NOT be used on the Chicago office internal network.
If an authentication attempt is suspicious, MFA must be used, regardless of the user location.

Any disruption of legitimate authentication attempts must be minimized.

General Requirements

Litware wants to minimize the deployment of additional servers and services in the Active Directory forest

How should you configure Group3? To answer, select the appropriate options in the answer area.

Select an answerA Microsoft 365 group in Microsoft 365 Admin CenterA security group in Active Directory users and computersA security group in Azure Active Diretory Admin Center

Office 365 Group in Microsoft 365 admin center. Here is what it says right on the Policy config screen: "Select which users or groups get this policy. Groups must be email-enabled." Security groups will NOT show up in the list of available groups

Correct Answer. Here is what it says right on the Policy config screen: "Select which users or groups get this policy. Groups must be email-enabled." Security groups will NOT show up in the list of available groups

2 / 3

You need to create Group3.
What are two possible ways to create the group?

a Microsoft 365 group in the Microsoft 365 admin center

a mail-enabled security group in the Microsoft 365 admin center

. a security group in the Microsoft 365 admin center

a distribution list in the Microsoft 365 admin center

This is about getting members from a group to assign labels. The only requirement is that the group has an email address, so a distribution list works.

3 / 3

Which IP address space should you include in the Trusted IP MFA configuration?

131.107.83.0/28

192.168.16.0/20

172.16.0.0/24

192.168.0.0/20

A is the answer. The trusted IPs can include private IP ranges only when you use MFA Server. For cloud-based Azure Multi-Factor Authentication, you can only use public IP address ranges. https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-mfa-mfasettings#mfa-service-settings

This is the requirement: Pilot users must use MFA unless they are signing in from the internal network of the Chicago office. MFA must NOT be used on the Chicago office internal network. This means you need to add a named location. Named locations can be configured by IP range or by country/region. If you go to Conditional Access -> Named locations, it's pretty clear you need to add a public IP range. Even the example given by MS is a public IP range: "Add a new IP range (ex: 40.77.182.32/27)".
