SC-200 Practice Test 28 — 15 Questions

Question 1

A threat hunter wants to use Microsoft Sentinel to hunt for signs of brute-force attacks against Azure AD (now Microsoft Entra ID). Which data connector should be enabled to ingest sign-in logs?

Accepted Answer

Microsoft Entra ID. Microsoft Entra ID (formerly Azure AD) connector. This connector ingests sign-in logs, which contain authentication attempts and can be used to detect brute-force attacks. Option A (Windows Security Events via AMA) captures on-premises Windows security events, not cloud sign-ins. Option B (DNS Preview) ingests DNS query logs, not sign-in logs. Option C (Microsoft Entra ID Audit Logs) captures audit logs (e.g., user management, configuration changes), not authentication sign-in logs. Therefore, only Option D provides the necessary sign-in log data for hunting brute-force attacks.

Answer

Windows Security Events via AMA

Answer

DNS (Preview)

Answer

Microsoft Entra ID Audit Logs

Question 2

A security analyst needs to identify incidents in Microsoft Sentinel that are related to IP addresses known to be associated with a specific threat actor. The analyst has a CSV file containing a list of these IP addresses. Which feature should the analyst use to make this list available for queries in Sentinel?

Accepted Answer

Watchlist. A Watchlist in Microsoft Sentinel allows you to import a CSV file containing IP addresses and use it directly in KQL queries via the _GetWatchlist() function. This is the correct feature because it is specifically designed for storing and querying static reference data, such as known threat actor IPs, without requiring custom ingestion or transformation.

Answer

Custom Log

Answer

Threat Intelligence indicator

Answer

Bookmark

Question 3

A threat hunter wants to proactively identify devices that may have been compromised by a known adversary using DLL side-loading techniques. Which Microsoft Sentinel solution or feature should the hunter leverage to create custom detection rules based on the latest threat intelligence?

Accepted Answer

Threat Intelligence integration with analytics rules. Microsoft Sentinel's Threat Intelligence integration allows you to import threat indicators (IOCs) from various sources and use them in analytics rules to detect known adversary techniques like DLL side-loading. By creating custom analytics rules that reference threat intelligence data, the hunter can proactively identify compromised devices based on the latest intel. This directly addresses the requirement to leverage threat intelligence for custom detection.

Answer

User and Entity Behavior Analytics (UEBA)

Answer

Automation rules with playbooks

Answer

Custom workbooks

Question 4

Which THREE indicators of compromise (IOCs) are commonly used in Microsoft Sentinel to detect advanced persistent threats (APTs)? (Choose THREE.)

Accepted Answer

Suspicious domains and URLs.. Option A is correct because suspicious domains and URLs are classic network-based IOCs that Microsoft Sentinel ingests via threat intelligence connectors and matches against DNS, proxy, and firewall logs to surface APT beaconing or phishing infrastructure. Option C is correct because SHA256 file hashes of known malware are high-fidelity, atomic IOCs that Sentinel uses in scheduled analytics rules and the Threat Intelligence matching rule to detect malicious binaries on endpoints and in file events. Option E is correct because IP addresses of known command-and-control servers are standard network IOCs that Sentinel correlates with CommonSecurityLog, Azure Firewall, and DNS data to identify active C2 communication. Option B is not an IOC but a vulnerability assessment artifact describing exposure rather than evidence of compromise, and Option D is a normal operational event (e.g., Event ID 4624) that only becomes suspicious in context, not a standalone IOC.

Answer

Vulnerability scan results.

Answer

Windows event IDs for successful logins.

Question 5

A company uses Microsoft Defender for Cloud with Defender for Servers enabled. The security team wants to integrate a third-party vulnerability assessment solution (e.g., Qualys) and have findings appear in the Defender for Cloud recommendations. What must be done?

Accepted Answer

Install the Qualys agent on the VMs and configure the vulnerability assessment solution in Defender for Cloud.. To integrate a third-party vulnerability assessment solution like Qualys with Microsoft Defender for Cloud, you must install the Qualys agent on the VMs and then configure the vulnerability assessment solution in Defender for Cloud. This allows Defender for Cloud to receive and display the vulnerability findings from Qualys as part of its security recommendations. Without this explicit configuration, Defender for Cloud cannot ingest third-party scanner data.

Answer

Enable the built-in Microsoft Defender Vulnerability Management (MDVM) solution; it automatically integrates with any third-party scanner.

Answer

Set up automatic provisioning of the Log Analytics agent and enable vulnerability assessment in the regulatory compliance dashboard.

Answer

Nothing; Defender for Cloud automatically scans all Azure VMs for vulnerabilities using the integrated Qualys scanner.

Question 6

A company has multiple Azure subscriptions under a management group. They want to ensure that all VMs across all subscriptions have Microsoft Defender for Cloud's vulnerability assessment solution (using the Microsoft Defender Vulnerability Management engine) enabled. They also want to automatically remediate any non-compliant VMs by enabling the VA solution when a VM is missing it. Which combination of policy initiatives and automation should they use?

Accepted Answer

Assign the 'Configure machines to receive a vulnerability assessment provider' policy with 'DeployIfNotExists' effect and set it to auto-remediate at the management group-level scope.. The 'Configure machines to receive a vulnerability assessment provider' policy with the 'DeployIfNotExists' effect directly deploys the Microsoft Defender Vulnerability Management (MDVM) extension to any VM that lacks it. By assigning this policy at the management group scope and enabling automatic remediation, the policy will automatically remediate non-compliant VMs without requiring additional runbooks or scripts, fulfilling both the detection and automatic remediation requirements.

Answer

Assign the 'Azure Security Benchmark' initiative at the management group, enable automatic remediation for the 'Vulnerability assessment should be enabled on your virtual machines' policy.

Answer

Assign the 'Defender for Cloud' initiative with the 'Configure machines to receive a vulnerability assessment provider' policy, and configure a remediation task with a deployment script.

Answer

Assign the 'Azure Security Benchmark' initiative and create an Azure Automation runbook triggered by a compliance alert to enable VA.

Question 7

A security analyst needs to connect a Palo Alto Networks firewall to Microsoft Sentinel to ingest logs. The firewall supports Syslog and Common Event Format (CEF). Which data connector should the analyst use?

Accepted Answer

Palo Alto Networks (via Syslog CEF). The Palo Alto Networks firewall supports sending logs in Common Event Format (CEF) over Syslog, and Microsoft Sentinel provides a dedicated data connector specifically for Palo Alto Networks (via Syslog CEF). This connector parses the CEF-formatted syslog messages using a Log Analytics agent or AMA, normalizing fields into the CommonSecurityLog table for seamless ingestion. Using the vendor-specific connector ensures proper field mapping and schema alignment, unlike a generic CEF connector which may not handle Palo Alto's specific CEF extensions correctly.

Answer

Common Event Format (CEF) via Syslog (generic)

Answer

Syslog (without CEF)

Answer

Custom Text Logs

Question 8

A security analyst is investigating a sophisticated attack that involved multiple devices. The analyst needs to create a custom detection rule in Microsoft 365 Defender that triggers when a process with a specific SHA256 hash is executed on any device AFTER an attacker-controlled file is created on another device. Which approach should the analyst use to build this detection?

Accepted Answer

Create a custom detection rule using an advanced hunting query that joins DeviceFileEvents and DeviceProcessEvents, and schedule it in Microsoft 365 Defender.. The requirement is to correlate two distinct events (file creation on one device and process execution on another) across time and devices. An advanced hunting query in Microsoft 365 Defender can join DeviceFileEvents and DeviceProcessEvents tables using a common indicator (e.g., attacker-controlled file hash) and schedule the query as a custom detection rule. This is the only native Microsoft 365 Defender approach that supports multi-device, multi-event correlation with scheduled evaluation.

Answer

Use the Microsoft 365 Defender incident creation rule to generate an incident when the behavior is observed.

Answer

Use Microsoft Sentinel analytics rules with a data connector to Microsoft 365 Defender.

Answer

Use Microsoft Defender for Cloud's workload protection alerts.

Question 9

A SOC team uses Microsoft Sentinel and wants to ingest custom log events from an on-premises Linux application that writes to a local file. The team sets up the Log Analytics agent on the Linux server and configures a data connector. Which of the following is the necessary configuration step to collect the custom log file?

Accepted Answer

Use the Custom Logs feature in the Log Analytics workspace to specify the path to the application log file and define the log type name.. The Custom Logs feature in the Log Analytics workspace is specifically designed to ingest text-based log files from on-premises Linux servers via the Log Analytics agent. You must specify the exact file path (e.g., /var/log/myapp.log) and define a custom log type name (e.g., MyApp_CL) to parse the file and send the data to a custom table in the Log Analytics workspace. This is the only method that directly collects custom application log files without requiring syslog or API-based ingestion.

Answer

Create a Syslog data connector and specify the facility and severity to filter the application logs from /var/log.

Answer

Configure the Log Analytics agent to collect performance counters for the application process.

Answer

Deploy a Log Analytics gateway and configure the application to write directly to the gateway using the HTTP Data Collector API.

Question 10

A company runs SQL Server on Azure Virtual Machines (IaaS). The security team wants to enable Advanced Threat Protection (ATP) to detect threats like SQL injection against these SQL Server instances. Which single action is required to achieve this?

Accepted Answer

Enable Microsoft Defender for SQL on the Azure subscription or at the SQL Server resource level.. To enable Advanced Threat Protection (ATP) for SQL Server on Azure VMs, you must enable Microsoft Defender for SQL at the Azure subscription or SQL Server resource level. This activates the SQL-specific threat detection capabilities, including alerts for SQL injection, anomalous access patterns, and suspicious activities. Without this, the SQL Server instances lack the dedicated security monitoring that ATP provides.

Answer

Install the SQL Server IaaS Agent extension on each virtual machine.

Answer

Enable just Microsoft Defender for Servers on the subscription.

Answer

Configure an Azure SQL firewall rule to allow only trusted IP addresses.

Question 11

A security team wants to automatically block an IP address in Azure Firewall when Microsoft Sentinel detects a high number of failed logins from that IP. Which automation approach should they use?

Accepted Answer

Create an automation rule that triggers on incident creation and runs a playbook that uses the Azure Firewall connector to add a rule.. It uses an automation rule triggered on incident creation to run a playbook, which can leverage the Azure Firewall connector to add a blocking rule. This approach directly integrates Sentinel's detection of a high number of failed logins with automated remediation in Azure Firewall, ensuring a real-time response without manual intervention.

Answer

Create an automation rule that triggers a playbook directly.

Answer

Create a scheduled analytics rule that runs a playbook.

Answer

Configure a Logic App to poll Sentinel alerts and block IPs.

Question 12

A SOC analyst is creating an automation rule in Microsoft Sentinel to trigger a playbook when a new incident is created. The analyst wants the rule to apply only to incidents that have a severity of 'High' and where the 'User' entity is present. Which condition configuration should the analyst use?

Accepted Answer

Set 'Incident severity equals High' and 'Entity type contains User'. Microsoft Sentinel automation rules evaluate conditions at the incident level, not the alert level. The 'Incident severity equals High' condition filters by incident severity, and 'Entity type contains User' checks that the incident's entities include a User entity, which is required for the playbook to receive entity context.

Answer

Set 'Incident severity equals High' and 'Incident tag contains User'

Answer

Set 'Alert severity equals High' and 'Alert entity type contains User'

Answer

Set 'Incident provider equals Microsoft Sentinel' and 'Entity type contains User'

Question 13

Your security operations center (SOC) uses Microsoft Sentinel. An incident is created from a fusion alert. What does Fusion technology do?

Accepted Answer

Correlates alerts from different products to detect multi-stage attacks. Microsoft Sentinel's Fusion technology is a correlation engine that stitches together low-fidelity alerts and signals from multiple sources (Microsoft and third-party products) into high-fidelity incidents representing multi-stage attacks. It uses machine learning models built on attack kill-chain patterns to detect sequences like a suspicious sign-in followed by anomalous resource creation. This is why Fusion incidents are typically high severity and span multiple products.

Answer

Uses machine learning to detect suspicious user behavior

Answer

Runs queries at scheduled intervals to detect threats

Answer

Detects unusual patterns in Azure activity logs

Question 14

You are configuring Microsoft Defender for Cloud Apps session controls for a SharePoint site containing sensitive data. Which condition must be met to apply real-time monitoring?

Accepted Answer

Users must be configured with Conditional Access policies from Microsoft Entra ID.. Microsoft Defender for Cloud Apps session controls for SharePoint require users to be routed through the Cloud App Security proxy, which is invoked by Conditional Access policies in Microsoft Entra ID. Conditional Access app controls apply session policies to traffic when users access SharePoint, enabling real-time monitoring. The Microsoft Entra ID application proxy is designed for on-premises apps, not for SaaS apps like SharePoint Online. Therefore, the correct prerequisite is having Conditional Access policies configured.

Answer

The SharePoint site must be added as a custom app in Defender for Cloud Apps.

Answer

Users must access the site through Microsoft Entra ID application proxy.

Answer

A browser extension must be installed on all client devices.

Question 15

A cloud security administrator needs to ensure that all Azure virtual machines have the Microsoft Defender for Cloud agent (Log Analytics agent) installed automatically when they are provisioned. Which configuration should be set in Microsoft Defender for Cloud?

Accepted Answer

Enable auto-provisioning in the Defender for Cloud environment settings.. Microsoft Defender for Cloud includes an auto-provisioning setting that, when enabled, automatically installs the Log Analytics agent (Microsoft Monitoring Agent) on all existing and newly provisioned Azure virtual machines. This setting is configured in the Defender for Cloud environment settings under 'Auto provisioning' and ensures seamless coverage without manual intervention or additional policy management.

Answer

Deploy a custom Azure Policy to install the agent on all VMs.

Answer

Use an Azure Automation runbook to install the agent on newly created VMs.

Answer

Enable Azure Update Management on the VMs.
