Question 2

A company uses digital signatures to ensure that a sender cannot later deny having sent a message. Which security principle does this primarily address?

Accepted Answer

Non-repudiation. Digital signatures use asymmetric cryptography (e.g., RSA or ECDSA) to bind a signer's identity to a message. The signature is created with the sender's private key and verified with their public key, providing cryptographic proof of origin. This directly enforces non-repudiation because the sender cannot plausibly deny having signed the message, as only they possess the private key.

Question 3

A legal team is preparing for a lawsuit and needs to perform a detailed investigation of user activities across Microsoft 365 services. They need to view the 'before' and 'after' values whenever a critical item in SharePoint or Exchange is updated or deleted. The investigation requires high-volume export performance and the ability to search by specific activities like 'MailboxFolderAccess' and 'Send'. Which Microsoft Purview solution should be enabled and configured to meet these advanced auditing requirements?

Accepted Answer

Microsoft Purview Audit (Premium). Microsoft Purview Audit (Premium) is required because it captures detailed 'before' and 'after' values for critical updates and deletions in SharePoint and Exchange, supports high-volume export performance, and allows searching for specific activities like 'MailboxFolderAccess' and 'Send'. These capabilities go beyond the Standard audit log, which only records basic event metadata without the old/new values and lacks the advanced search and export throughput needed for litigation.

Question 6

A security analyst is using Microsoft 365 Defender to investigate a sophisticated multi-stage attack. The analyst needs to query data across endpoints, email, and identity logs to identify the attacker's behavior patterns and correlate events. Which Microsoft 365 Defender capability should the analyst use?

Accepted Answer

Advanced hunting. Advanced hunting is the correct capability because it provides a Kusto Query Language (KQL)-based query interface that allows the security analyst to perform custom, cross-domain searches across data from endpoints (Microsoft Defender for Endpoint), email (Microsoft Defender for Office 365), and identity logs (Microsoft Defender for Identity). This enables the correlation of events and identification of attacker behavior patterns across a multi-stage attack, which is not possible with the other options.

Question 8

A company's security team implements a system where every access attempt to sensitive data is recorded, including who accessed the data and when. The logs are regularly reviewed to detect unauthorized access and to hold users accountable for their actions. Which security goal is primarily being addressed by this logging practice?

Accepted Answer

Non-repudiation. Non-repudiation ensures that a user cannot deny having performed an action. By recording who accessed sensitive data and when, the logging practice creates an audit trail that can prove a specific user accessed the data at a specific time, thereby preventing the user from denying that access. This directly addresses the security goal of non-repudiation.

Question 10

Refer to the exhibit. You are reviewing a Microsoft Defender for Cloud Apps alert. Based on the evidence, which action should you take first?

Accepted Answer

Request file upload for analysis. The alert evidence shows a suspicious file upload activity, which could indicate a potential malware or data exfiltration attempt. Requesting file upload for analysis (Option D) is the correct first action because it allows Defender for Cloud Apps to perform deep content inspection and threat detection before taking any disruptive actions like suspending the user or isolating the device, ensuring that the response is proportionate and evidence-based.

Answer

Mark the alert as benign

Answer

Suspend the user account

Answer

Isolate the device immediately

A security administrator uses Microsoft Entra ID Protection to identify and respond to identity-based risks. Which two types of risk detections can be reviewed in Microsoft Entra ID Protection? (Choose two.)

Accepted Answer

Sign-in risk. Microsoft Entra ID Protection evaluates identity-based risks by analyzing two primary detection types: sign-in risk and user risk. Sign-in risk assesses the probability that a specific authentication attempt is unauthorized, while user risk evaluates the likelihood that a user account has been compromised based on aggregated suspicious activities.

Answer

Application permission risk

Answer

Device compliance risk

Question 12

A financial services organization needs to prevent communication between its research analysts and investment bankers to comply with regulatory requirements. Which Microsoft Purview solution should the compliance team implement?

Accepted Answer

Information Barriers. Information Barriers (IB) in Microsoft Purview is specifically designed to prevent communication and collaboration between certain user groups to comply with regulatory requirements, such as those in financial services that require separation between research analysts and investment bankers.

Question 15

A user receives an encrypted email from their bank. They use their private key to decrypt the message. After reading it, they verify that the message content has not been altered during transit. Which security principle is primarily demonstrated by the verification that the content was not altered?

Accepted Answer

Integrity. The verification that the message content has not been altered during transit directly demonstrates the principle of integrity. Integrity ensures that data remains unchanged from its source to its destination, typically enforced through cryptographic hashing or digital signatures. In this scenario, the user's ability to confirm that the email content was not tampered with relies on a hash or signature verification mechanism, which is the core function of integrity protection.
