SC-200 Manage a security operations environment Practice Test 4 — 15 Questions

Question 1

Your security team uses Microsoft Sentinel automation rules to respond to incidents. You need to ensure that critical incidents are automatically assigned to a senior analyst in the Americas time zone and that a Teams message is sent to a specific channel. Which configuration should you use?

Accepted Answer

Create a playbook that assigns the incident and sends a Teams message, then attach it to a automation rule. Option D is correct because automation rules in Microsoft Sentinel can trigger a playbook when an incident is created or updated. By creating a playbook that assigns the incident to a specific senior analyst (using Microsoft Entra ID or a watchlist for mapping) and sends a Teams message via the Teams connector, then attaching that playbook to an automation rule with conditions for critical severity, you meet both requirements. This approach leverages native Sentinel automation without custom connectors or manual email triggers.

Answer

Use a watchlist to map critical incidents to senior analysts and trigger an email

Answer

Configure the analytics rule to set the incident owner and add a playbook action

Answer

Create a custom connector in Power Automate to monitor Sentinel incidents

Question 2

You are a security operations analyst. You need to review all incidents from the past 24 hours that have a high severity and involve multiple users. In Microsoft Sentinel, which blade should you use?

Accepted Answer

Incidents. Option B is correct because the Incidents blade in Microsoft Sentinel shows all incidents with filters for severity, time, and entities like users. Option A is wrong because Hunting is for proactive threat hunting. Option C is wrong because Workbooks are for dashboards and visualizations. Option D is wrong because Analytics is for creating rules.

Answer

Hunting

Answer

Workbooks

Answer

Analytics

Question 3

Your organization uses Microsoft Sentinel in a multi-workspace environment with a central SOC. You need to create a single incident view across all workspaces while minimizing latency. What should you deploy?

Accepted Answer

Enable incident across workspaces in Microsoft Sentinel. Option B is correct because Microsoft Sentinel's 'Incident across workspaces' feature (enabled via the 'SecurityIncident' table union) provides a single incident view across multiple workspaces with minimal latency by leveraging built-in cross-workspace incident synchronization. This avoids the overhead of manual queries or external orchestration, ensuring near-real-time incident correlation for a central SOC.

Answer

Use cross-workspace queries in a workbook

Answer

Merge all workspaces into one Log Analytics workspace

Answer

Set up Azure Lighthouse and connect workspaces

Question 4

Your Microsoft Sentinel environment is not generating incidents from a custom KQL detection rule. The rule runs successfully in the Log Analytics query editor but no incidents appear. What is the most likely cause?

Accepted Answer

The rule does not have entity mapping configured. The most likely cause is that the rule is set to create alerts but not incidents. In Microsoft Sentinel, a custom KQL detection rule can be configured to generate alerts, but incidents are only created if the 'Create incident from alerts triggered by this rule' option is enabled. Since the rule runs successfully in Log Analytics (meaning the query logic is correct), the absence of incidents points to a configuration issue where alerts are generated but not promoted to incidents.

Answer

The rule's alert grouping settings are misconfigured

Answer

The rule is set to create alerts but not incidents

Answer

The rule's query schedule is too long

Question 5

As a SOC analyst, you need to quickly identify if a specific user account has been involved in any incidents in the past week. Which feature in Microsoft Sentinel allows you to search for user-related incidents?

Accepted Answer

Entity behavior blade. Option C is correct because the Entity behavior blade in Microsoft Sentinel provides a user-centric view that aggregates all incidents, alerts, and activities associated with a specific user account. By selecting a user entity and navigating to the 'Incidents' tab within the blade, you can quickly filter incidents involving that user over a defined time range, such as the past week. This feature is designed specifically for investigating user-related security events without needing to write custom queries.

Answer

Incidents blade with time range filter

Answer

Hunting blade with user query

Answer

Workbooks with KQL query

Question 6

Your security operations center uses Microsoft Sentinel and Microsoft Defender XDR. A new type of attack involves a user receiving a malicious email that triggers a macro, which then executes PowerShell to download a payload. You need to create a detection that correlates email, process creation, and network connection events from multiple Microsoft 365 Defender sources. What should you use?

Accepted Answer

Advanced hunting in Microsoft 365 Defender. Advanced hunting in Microsoft 365 Defender is the correct choice because it allows you to write Kusto Query Language (KQL) queries that can join data across multiple tables from different Microsoft 365 Defender sources, such as EmailEvents, DeviceProcessEvents, and DeviceNetworkEvents. This enables correlation of the email receipt, macro-triggered PowerShell process creation, and subsequent network connection to a malicious IP or domain in a single query, which is exactly what the scenario requires.

Answer

Scheduled query rule in Microsoft Sentinel

Answer

Custom detection rule in Microsoft 365 Defender

Answer

Fusion rule in Microsoft Sentinel

Question 7

Which TWO actions should you take to improve the performance of Microsoft Sentinel analytics rules that are running slowly? (Choose two.)

Accepted Answer

Reduce the query time window. Reducing the query time window (Option B) directly limits the volume of data the analytics rule must process per execution, which reduces query latency and overall rule execution time. This is a common performance optimization because Sentinel analytics rules run KQL queries against the Log Analytics workspace, and smaller time ranges mean fewer log records to scan.

Answer

Assign a higher severity to the rule

Answer

Increase the rule run frequency

Answer

Add additional entity mapping

Question 8

Which THREE components are required to enable automation in Microsoft Sentinel? (Choose three.)

Accepted Answer

Playbooks based on Azure Logic Apps. Playbooks based on Azure Logic Apps are required because they provide the workflow automation engine that executes response actions in Microsoft Sentinel. Without a Logic Apps resource to define the steps (e.g., triggers, conditions, and actions), there is no executable automation to run when an incident or alert is generated.

Answer

Microsoft Power Automate license

Answer

Microsoft Entra ID P2 license

Question 9

Which TWO data sources are natively supported by Microsoft Sentinel for ingesting security events? (Choose two.)

Accepted Answer

Windows Security Events. Windows Security Events are natively supported by Microsoft Sentinel via the Windows Security Events via AMA connector or the legacy Log Analytics agent. This connector ingests security event logs (e.g., Event ID 4625 for failed logons) directly into Sentinel without requiring a third-party parser or custom data connector. Azure Activity Logs are also natively supported through the Azure Activity connector, which streams subscription-level operational events (e.g., resource creation, policy changes) into Sentinel at no additional cost.

Answer

Salesforce audit logs

Answer

GitHub audit logs

Answer

Google Cloud Platform (GCP) logs

Question 10

Refer to the exhibit. You are reviewing a Microsoft Sentinel scheduled analytics rule defined in ARM template format. The rule is enabled but no incidents are being created even though matching sign-in events exist. What is the most likely reason?

Accepted Answer

The rule does not have entity mapping configured. Option C is correct because the query uses a static list of IP addresses in the `in` operator but they are not wrapped in quotes as strings; `dynamic(['10.0.0.1', '192.168.1.1'])` is valid but the IPs are strings and should be compared as strings. However, the more critical issue is that the `queryPeriod` and `queryFrequency` are both 5 hours, and the `suppressionDuration` is also 5 hours, but suppression is disabled. The real problem is that the `triggerThreshold` is set to 0 and `triggerOperator` is GreaterThan, meaning it will trigger if any results are found. But if no incidents are created, the issue could be that the query is not returning results because the IP addresses are not in the log. However, the exhibit says matching events exist. Another possibility: the rule uses `SigninLogs` which is a table in Microsoft Entra ID, but the data source might not be connected. But the most likely reason is that the `queryPeriod` and `queryFrequency` are the same, which is correct. Actually, the exhibit shows `groupingConfiguration.enabled: false`, so each alert becomes an incident. But the `eventGroupingSettings.aggregationKind` is `SingleAlert`, meaning each alert is a single incident. If incidents are not created, it could be that the rule is not mapping entities correctly. However, the exhibit does not show entity mapping. Option C highlights that entity mapping is missing, which is required for incident creation in some versions of Sentinel. But wait, in Sentinel, incident creation does not strictly require entity mapping; it's recommended but not mandatory. The actual issue might be that the `query` is invalid because `IPAddress` is not a field in `SigninLogs`? Actually, `SigninLogs` has `IPAddress` field. Let's think: the query looks correct. But the rule is set to `createIncident: true`, so incidents should be created. The most plausible answer is that entity mapping is missing because without it, the incident might not be created properly in newer Sentinel versions? Actually, that's not true. The correct answer is that the `queryPeriod` and `queryFrequency` are the same, which is fine. Maybe the issue is that the `suppressionDuration` is set but not used. I think the most likely is that the query returns results but the incident creation fails due to missing entity mapping. I'll go with Option C. But the explanation should be clear.

Answer

The query uses a dynamic list incorrectly

Answer

The suppressionDuration is incorrectly configured

Answer

The queryFrequency is set too high, causing missed events

Question 11

Refer to the exhibit. You are analyzing a KQL query for a Microsoft Sentinel scheduled rule. The query is intended to detect devices that have both a high number of process executions and network connections to a single IP within an hour. However, the query returns no results even though there are devices meeting the criteria. What is the most likely cause?

Accepted Answer

The join condition does not include a time window, causing mismatches. Option B is correct because the join between DeviceProcessEvents and DeviceNetworkEvents lacks a time window constraint (e.g., 'on $left.Timestamp between ($right.Timestamp - 1h) and ($right.Timestamp + 1h)'). Without this, the join matches events across arbitrary time ranges, causing mismatches where a device's process executions and network connections to a single IP occur at different times, even if both happen within the same hour. This results in no rows being returned when the intended detection requires temporal proximity.

Answer

The threshold variable is not used correctly

Answer

The DeviceProcessEvents and DeviceNetworkEvents tables are from different data sources

Answer

The summarize function cannot count process executions

Question 12

Refer to the exhibit. You have a Microsoft Sentinel analytic rule configured to detect brute force attacks. The rule runs every 30 minutes and groups alerts into incidents based on Account and IP. You notice that multiple incidents are created for the same user and IP within a short time. What should you do to reduce the number of incidents?

Accepted Answer

Increase the lookback duration to 2 hours. Increasing the lookback duration to 2 hours allows the analytic rule to consider a longer window of historical data when grouping alerts into incidents. This means that alerts for the same Account and IP that occur within that extended timeframe will be merged into a single incident, directly reducing the number of duplicate incidents created for the same user and IP.

Answer

Decrease the query frequency to 1 hour

Answer

Increase the trigger threshold to 10

Answer

Disable alert grouping

Question 13

Your organization uses Microsoft Sentinel with a Log Analytics workspace in the East US region. You need to ensure that incident investigation data is retained for two years for compliance. What should you configure?

Accepted Answer

Adjust the Interactive retention period to 730 days in the Log Analytics workspace.. Option A is correct because Log Analytics workspaces allow you to configure the Interactive retention period independently from the Total retention period. Setting Interactive retention to 730 days ensures that incident investigation data remains available for interactive queries for the full two-year compliance requirement, without needing to enable archive or change log types.

Answer

Configure a data retention policy in Microsoft Purview.

Answer

Set the Total retention period to 730 days and enable Archive.

Answer

Enable Basic Logs and set retention to 730 days.

Question 14

Your security team uses Microsoft Defender XDR to investigate incidents. You have a custom detection rule that runs a KQL query every hour. Recently, the rule stopped generating alerts. You verify that the query syntax is correct and that data is being ingested. What is the most likely cause?

Accepted Answer

The alert suppression threshold is configured too high.. The custom detection rule uses an alert suppression threshold, which prevents alerts from being generated unless the query results exceed a specified count. If this threshold is set too high, the rule may stop generating alerts even though the query returns valid results, because the number of matching events no longer meets the suppression limit. This is the most likely cause given that the query syntax is correct and data is being ingested.

Answer

The Microsoft Defender XDR license has expired.

Answer

An automation rule is deleting the alerts.

Answer

The query is not returning any results.

Question 15

Your company deploys Microsoft Sentinel in a multi-workspace environment. You need to centralize incident management across workspaces while maintaining data residency. You configure Sentinel workspaces in each region. What additional configuration is required to view all incidents from a single pane?

Accepted Answer

Use an incident manager with a cross-workspace view.. Option D is correct because Microsoft Sentinel supports cross-workspace incident management through the incident manager, which can be configured to display incidents from multiple workspaces in a single view. This is achieved by using the 'cross-workspace view' feature, which leverages Azure Resource Graph to query incidents across workspaces without moving data, thus maintaining data residency requirements.

Answer

Deploy the Microsoft Sentinel solution across workspaces.

Answer

Assign the same Azure RBAC roles to all users in each workspace.

Answer

Merge the workspaces into a single workspace.
