The AB-650 certification is an essential milestone in your Azure journey. Our practice tests simulate the real exam format, helping you build confidence and identify knowledge gaps. Review the detailed explanations provided after each question to deeply understand the underlying cloud concepts.
Sample AB-650 Practice Questions
Question 1
You are configuring custom domain verification for a new secondary domain, hr-contoso.com, in your Microsoft 365 tenant. The production web services for this domain are active on third-party servers. Which DNS record should you add at the registrar to verify domain ownership without interrupting web or existing mail traffic?
- A TXT record containing the MS=ms verification code
- An MX record pointing directly to mail.protection.outlook.com
- A CNAME record for autodiscover.contoso.com
- An SRV record for SIP federation
Adding a TXT record with the MS=ms verification string verifies ownership directly without altering IP routing, MX priorities, or existing web traffic.
Question 2
You need to assign an administrative role to a helpdesk engineer who only needs to reset passwords for standard users and monitor Microsoft 365 service health. Following the principle of least privilege, which role should you assign?
- Helpdesk Administrator
- Global Administrator
- User Administrator
- Security Administrator
The Helpdesk Administrator role allows resetting passwords for non-administrators and monitoring service health without granting global directory permissions.
Question 3
Your organization is enabling Microsoft 365 Backup for high-speed recovery against ransomware. Which workloads can be natively backed up using the Microsoft 365 Backup service in the admin center?
- SharePoint Online, OneDrive, and Exchange Online
- Azure SQL databases and on-premises Hyper-V hosts
- Endpoint physical hard drives and BIOS firmware
- Third-party Salesforce databases only
Microsoft 365 Backup natively protects SharePoint Online document libraries, OneDrive user accounts, and Exchange Online mailboxes within the tenant boundary.
