Question 3

A company's security policy requires that all data transferred between the corporate data center and the cloud must be protected from unauthorized access during transmission. They use encryption protocols such as TLS to achieve this. Which security goal is primarily being addressed?

Accepted Answer

Confidentiality. Confidentiality is the security goal that ensures data is not disclosed to unauthorized entities. By using encryption protocols such as TLS, the data in transit is rendered unreadable to any party that intercepts the traffic, directly protecting against unauthorized access during transmission.

Answer

Integrity

Answer

Availability

Answer

Non-repudiation

Question 4

A company stores critical financial reports in a SharePoint Online library. To ensure that the reports have not been tampered with, the security team compares a calculated hash of each file against a stored baseline. This verification process primarily protects which security goal?

Accepted Answer

Integrity. The verification process uses hash comparison to detect unauthorized changes to files, which directly protects data integrity. Integrity ensures that data has not been altered or tampered with during storage or transit. In SharePoint Online, hashing (e.g., SHA-256) creates a unique fingerprint; if the calculated hash matches the stored baseline, the file is unchanged.

Answer

Confidentiality

Answer

Availability

Answer

Non-repudiation

Question 5

A company stores sensitive customer data in an Azure SQL database. To protect this data, the database files are encrypted at rest using Transparent Data Encryption (TDE). Additionally, all network traffic between the application and the database is encrypted using TLS. Which security goal is primarily addressed by these encryption measures?

Accepted Answer

Confidentiality. Transparent Data Encryption (TDE) encrypts data at rest, meaning the database files on disk are encrypted so that unauthorized access to the physical storage cannot read the data. TLS encrypts data in transit between the application and the database, preventing eavesdropping or interception over the network. Together, these measures primarily ensure that sensitive customer data remains secret and inaccessible to unauthorized parties, which is the core goal of confidentiality.

Answer

Integrity

Answer

Availability

Answer

Non-repudiation

Question 6

A company's security team has adopted a strategy that assumes a breach has already occurred. They implement network segmentation, apply strict least privilege access, continuously verify all access requests, and never trust users or devices solely because they are inside the network perimeter. This approach best describes which security model?

Accepted Answer

Zero Trust. The scenario explicitly describes the core tenets of the Zero Trust model: assume breach, enforce least privilege, segment networks, and never trust any user or device based solely on network location. Zero Trust, as defined by NIST SP 800-207, mandates continuous verification of every access request, treating every request as if it originates from an untrusted network, which directly matches the company's strategy.

Question 7

A company stores financial reports in SharePoint Online that contain credit card numbers. The compliance team needs to automatically apply a sensitivity label that encrypts the documents when they detect credit card data. Which Microsoft Purview solution should they configure?

Accepted Answer

Information Protection. Microsoft Purview Information Protection (A) is the correct solution because it enables the creation of auto-labeling policies that can automatically apply a sensitivity label with encryption when credit card numbers are detected in SharePoint Online documents. This directly addresses the requirement to classify and protect sensitive data at rest based on content inspection.

Question 8

A company uses a cloud-based email service. The service provider ensures that the physical data centers are secure and that the email platform is patched and available. The company is responsible for managing user accounts and ensuring that employees use strong passwords. This division of responsibilities is an example of which concept?

Accepted Answer

Shared responsibility model. The scenario describes a clear division of security responsibilities between the cloud service provider (securing physical data centers, patching the platform) and the customer (managing user accounts, enforcing strong passwords). This is the core definition of the shared responsibility model, which is a foundational concept in cloud computing (as defined by NIST SP 800-145 and adopted by major providers like Microsoft 365). The model explicitly delineates that the provider is responsible for 'security of the cloud' (physical hosts, network, hypervisor) while the customer is responsible for 'security in the cloud' (user identities, data, client endpoints).

Answer

Answer

Zero Trust

Answer

Principle of least privilege

Question 9

A company uses Azure virtual machines for a production database. The security team wants to minimize the attack surface by blocking all inbound RDP (port 3389) traffic. However, administrators occasionally need to connect for maintenance. The team needs a solution that allows administrators to request temporary access to the RDP port, which is automatically revoked after a specified time. Which Microsoft Defender for Cloud feature should they use?

Accepted Answer

Just-in-time (JIT) VM access. Just-in-time (JIT) VM access is the correct feature because it specifically addresses the need to block inbound RDP (port 3389) traffic by default while allowing administrators to request temporary, time-bound access. When a request is approved, JIT dynamically modifies the network security group (NSG) to open the port for a specified duration, then automatically reverts the rule to deny all inbound traffic after the time expires. This directly minimizes the attack surface by eliminating persistent open management ports.

Question 12

A company uses Microsoft Entra ID (Microsoft Entra ID) for identity management. They want to automatically block sign-ins from users whose credentials have been compromised and require them to change their password before access is granted. Which Microsoft Entra ID capability should they use?

Accepted Answer

Microsoft Entra ID Protection. Microsoft Entra ID Protection is the correct capability because it automatically detects compromised credentials by analyzing telemetry from Microsoft's Threat Intelligence and the wider ecosystem. When a user's credentials are found in a known leak, Entra ID Protection can enforce a policy that blocks sign-in and requires the user to change their password via an integrated remediation workflow, directly addressing the scenario.
