SC-900 Describe the capabilities of Microsoft Entra Practice Question
A company wants to prevent users from using common passwords like 'Password123' and custom banned passwords such as 'Contoso2024' during sign-up or password change. They also need to apply a common list of banned passwords across tenant-wide. Which Microsoft Entra feature should they configure?
⚠ Common exam trap
Many candidates confuse Conditional Access (which controls access conditions) with password protection policies, or assume Identity Protection handles password bans when it actually focuses on risk detection, not password content enforcement.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra ID Password Protection
Microsoft Entra ID Password Protection allows administrators to enforce both a global banned password list (Microsoft-managed) and a custom banned password list (tenant-specific). This feature blocks weak passwords like 'Password123' and custom entries like 'Contoso2024' during sign-up or password change operations, making it the correct choice for tenant-wide password policy enforcement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Conditional Access
Why it's wrong here
Conditional Access policies are used to enforce organizational access requirements based on conditions like user location, device compliance, or sign-in risk. While they can block access for high-risk sign-ins or require MFA, they operate *after* a password has been entered and validated. They do not possess the capability to inspect or reject a password during the creation or reset process based on a banned list, making them unsuitable for preventing weak password choices.
- ✓
Microsoft Entra ID Password Protection
Why this is correct
Microsoft Entra ID Password Protection directly addresses the challenge of weak and commonly used passwords by integrating a global banned password list and enabling administrators to create custom banned lists specific to their organization. This service actively checks passwords during creation, reset, or change operations against these lists, preventing users from setting easily guessable or compromised credentials. It ensures stronger password hygiene by proactively blocking known weak patterns, directly fulfilling the requirement to prevent common passwords.
- ✗
Identity Protection
Why it's wrong here
Microsoft Entra ID Protection focuses on detecting and remediating identity-based risks, such as leaked credentials, impossible travel, or anomalous sign-in activities, often by triggering MFA or blocking access. While it identifies *risks associated with* compromised credentials, it does not directly enforce password creation policies or maintain lists of banned passwords. Its role is reactive to potential threats, not proactive in preventing the initial selection of weak passwords.
- ✗
Multifactor Authentication (MFA)
Why it's wrong here
Multifactor Authentication (MFA) significantly enhances security by requiring users to provide two or more verification factors to gain access, such as a password combined with a code from an authenticator app or a biometric scan. While MFA makes it much harder for attackers to compromise an account even if they know the password, it operates independently of the password creation process. MFA does not prevent users from choosing weak or common passwords; it merely adds an additional layer of protection *after* the password has been selected.
