Free Practice Questions for Google Security-Operations-Engineer Exam

Comprehensive and Detailed Explanation

The correct answer is Option C. The prompt specifies two critical, simultaneous requirements: immediate containment and preservation of forensic data.

Immediate Containment: The server is actively scanning the network, so it must be taken offline to prevent lateral movement and further compromise.

Forensic Preservation: The suspicion of persistence mechanisms means a full investigation is required. This investigation relies on volatile data (running processes, memory, active network connections) that must not be destroyed.

Option C is the only action that satisfies both requirements. Using a Google SecOps SOAR playbook to trigger the EDR integration's "quarantine" action instructs the EDR agent on the server to block all its network connections. This immediately contains the threat. However, the server itself remains running, which preserves all volatile forensic data for the investigation.

Option B (reboot) is incorrect because it is an eradication step that would destroy all volatile forensic evidence. Options A and D are incomplete containment or investigation steps that do not fully isolate the compromised host.

Exact Extract from Google Security Operations Documents:

Incident Response and Containment: When a critical asset is compromised, the first priority is containment. Google SecOps SOAR playbooks integrate with Endpoint Detection and Response (EDR) tools to automate this step.

EDR Integration Actions: The most common containment action is "Quarantine Host" or "Isolate Asset." This action instructs the EDR agent on the endpoint to block all network communications, effectively isolating it from the rest of the network. This step immediately stops the threat from spreading or communicating with a C2 server. A key benefit of this approach, as opposed to a shutdown or reboot, is that the host remains powered on, which preserves volatile memory and process data for forensic investigation.

The correct configuration is Option A. This answer addresses two key requirements from the question: the identity mechanism (Cloud Identity) and the required permission level (read-only access including detection rules).

Identity Mechanism (Google Group vs. Workforce Pool):

The prompt explicitly states the organization uses Cloud Identity as its identity provider (IdP). When Cloud Identity or Google Workspace is the IdP, the standard practice is to manage access using Google Groups. Users are added to a group, and IAM roles are granted to that group. Workforce identity federation (which uses workforce pools) is the mechanism used when integrating with a third-party IdP, such as Okta or Azure AD. Since the IdP is Cloud Identity, creating a Google Group is the correct approach. This eliminates options C and D.

Permission Level (roles/chronicle.viewer vs. roles/chronicle.limitedViewer):

The prompt requires "read-only access to all resources, including detection engine rules." The predefined Google SecOps IAM roles are specific about this distinction:

roles/chronicle.viewer (Chronicle API Viewer): Provides "Read-only access to Google SecOps application and API resources." This role includes permissions to view detection rules and retrohunts.

roles/chronicle.limitedViewer (Chronicle API Limited Viewer): Provides "Grants read-only access to Google SecOps application and API resources, excluding detection engine rules and retrohunts."

Therefore, roles/chronicle.limitedViewer (Option B) is incorrect because it excludes access to detection engine rules, which violates the prompt's requirement. The correct role is roles/chronicle.viewer (Option A), as it grants the necessary comprehensive read-only access.

Comprehensive and Detailed Explanation

The correct solution is Option B. This question requires a low-latency (5 minutes) notification for a silent source.

The other options are incorrect for two main reasons:

Dashboards vs. Notifications: Options C and D are incorrect because dashboards (both in Looker and Google SecOps) are for visualization, not active, real-time alerting. They show you the status when you look at them but do not proactively notify you of a failure.

Metric-Absence vs. Metric-Value: Google SecOps streams all its ingestion health metrics to Google Cloud Monitoring, which is the correct tool for real-time alerting. However, Option A is monitoring the "total ingested log count." This metric would require a threshold (e.g., count < 1), which can be problematic. The specific and most reliable method to detect a "silent source" (one that has stopped sending data entirely) is to use a metric-absence condition. This type of policy in Cloud Monitoring triggers only when the platform stops receiving data for a specific metric (grouped by collector_id) for a defined duration (e.g., five minutes).

Exact Extract from Google Security Operations Documents:

Use Cloud Monitoring for ingestion insights: Google SecOps uses Cloud Monitoring to send the ingestion notifications. Use this feature for ingestion notifications and ingestion volume viewing... You can integrate email notifications into existing workflows.

Set up a sample policy to detect silent Google SecOps collection agents:

In the Google Cloud console, select Monitoring.

Click Create Policy.

Select a metric, such as chronicle.googleapis.com/ingestion/log_count.

In the Transform data section, set the Time series group by to collector_id.

Click Next.

Select Metric absence and do the following:

Set Alert trigger to Any time series violates.

Set Trigger absence time to a time (e.g., 5 minutes).

In the Notifications and name section, select a notification channel.

The correct answer is Option C. The prompt asks for the most efficient and automated solution for handling SCCE findings and integrating with a ticketing system. This is the primary use case for Google Security Operations SOAR.

The native workflow is as follows:

SCCE detects a finding.

The finding is automatically ingested into Google SecOps SIEM, which creates an alert.

The alert is automatically sent to SecOps SOAR, which creates a case.

The SOAR case automatically triggers a playbook.

Option C describes this process perfectly. An administrator would disable the default playbook and enable a specific playbook that uses a pre-built integration (from the Marketplace) for the organization's ticketing system (e.g., ServiceNow, Jira). This playbook would contain an automated step to generate a ticket, thus fulfilling the requirement efficiently.

Option B is a manual process. Options A and D describe complex, custom-built data engineering pipelines, which are far less efficient than using the built-in SOAR capabilities.

Exact Extract from Google Security Operations Documents:

SOAR Playbooks and Integrations: Google SecOps SOAR is designed to automate and orchestrate responses to alerts. When an alert from a source like Security Command Center (SCC) is ingested and creates a case, it can be configured to automatically trigger a playbook.

Ticketing Integration: A common playbook use case is integration with an external ticketing system. Using a pre-built integration from the SOAR Marketplace, an administrator can add a step to the playbook (e.g., Create Ticket). This action will automatically generate a ticket in the external system and populate it with details from the alert, such as the finding, the affected resources, and the recommended remediation steps. This provides a seamless, automated workflow from detection to ticketing.

Comprehensive and Detailed Explanation

The correct answer is Option A. This question is about entity context enrichment and aliasing.

Endpoint telemetry from EDR and Windows Event Logs (like 4624) identifies users by their Windows Security Identifier (SID) (e.g., S-1-5-21-12345...). However, detection rules are more effective when they match on a human-readable and consistent identifier, like an email address or username, which is stored in principal.user.userid.

To "connect the dots" between the SID found in endpoint events and the userid, Google SecOps must ingest an authoritative user context data source. In a modern Windows environment, this source is Microsoft Entra ID (formerly Azure AD) or on-premises Active Directory.

Ingesting Entra ID logs as a USER_CONTEXT feed populates the SecOps entity graph. This allows the platform to automatically alias the SID from an endpoint log to the corresponding userid (e.g., jsmith@company.com) at ingestion time. This ensures the principal.user.userid field is correctly populated, allowing the detection rules to match.

Options B, C, and D are all additional event sources (like EDR) and would provide more SIDs, but they do not provide the central directory data needed to perform the aliasing.

Exact Extract from Google Security Operations Documents:

UDM enrichment and aliasing overview: Google Security Operations (SecOps) supports aliasing and enrichment for assets and users. Aliasing enables enrichment. For example, using aliasing, you can find the job title and employment status associated with a user ID.

How aliasing works: User aliasing uses the USER_CONTEXT event type for aliasing. This contextual data is stored as entities in the Entity Graph. When new Unified Data Model (UDM) events are ingested, enrichment uses this aliasing data to add context to the UDM event. For example, an EDR log might contain a principal.windows_sid. The enrichment process queries the entity graph (populated by your Active Directory or Entra ID feed) and populates the principal.user.userid and other fields in the principal.user noun.

This scenario describes an automated external approval, which is a key feature of Google Security Operations (SecOps) SOAR. The solution that "minimizes the effort required by the SOC analyst" is one that is fully automated and does not require the analyst to wait for an email and then manually resume the playbook.

The correct method (Option D) is to use the platform's built-in capabilities (often part of the "Flow" or "Siemplify" integration) to generate a unique approval link (or "Approve" / "Deny" links). These links are tokenized and tied to the specific playbook's execution. This link is then inserted as a placeholder into the email that is sent to the non-SecOps user via the "Send Email" (Gmail integration) action.

The playbook is then configured with conditional logic (e.g., a "Wait for Condition") to pause execution until one of the links is clicked. When the external user clicks the "Approve" or "Deny" link in their email, it sends a secure signal back to the SOAR platform. The playbook automatically detects this response and continues down the appropriate conditional path (e.g., "if approved, execute endpoint containment"). This process is fully automated and requires zero analyst intervention, perfectly meeting the requirements.

Options A, B, and C all require manual analyst action, which violates the core requirement of minimizing analyst effort.

To achieve improved coverage and reduced false positives "as quickly as possible," the correct action is to enable curated detections. These are pre-built rules managed entirely by Google, removing the need for internal development time.2

According to Google Security Operations documentation, Curated Detections are "built by our Google Cloud Threat Intelligence (GCTI) team, and are actively maintained to reduce manual toil in your team."3 The documentation explicitly highlights their speed and fidelity: "Our detections provide security teams with high quality, actionable, out-of-the-box threat detection content...4 This release helps understaffed and overstressed security teams... quickly identify threats."5

Furthermore, Curated Detections are categorized into "Precise" and "Broad" types to directly address false positive concerns.6 The documentation states: "Precise rules: Find malicious behavior with a higher degree of confidence with fewer false positives due to the more specific nature of the rule."7 By enabling these, an organization immediately gains high-fidelity coverage without the lead time required to "Develop" or "Design" custom YARA-L rules (Options C and D) or the potential noise of raw TIP data (Option B).8

The correct, low-impact solution for augmenting a Google-managed parser is to use a parser extension. The problem states that the base parser is still working, but needs to be supplemented to map two new fields.

Copying the entire parser (Option A) is a high-impact, high-maintenance solution ("Customer Specific Parser"). This action makes the organization responsible for all future updates and breaks the link to Google's managed updates, which is not a minimal-impact solution.

The intended, modern solution is the parser extension. This feature allows an engineer to write a small, targeted snippet of Code-Based Normalization (CBN) code that executes after the Google-managed base parser. This extension code can access the raw_log and perform the specific logic needed to extract the two unmapped fields and assign them to their proper Universal Data Model (UDM) fields.

This approach is the fastest to deploy and minimizes change management impact because the core parser remains managed and updated by Google, while the extension simply adds the custom logic on top. Option B, "Extract Additional Fields," is a UI-driven feature, but the underlying mechanism that saves and deploys this logic is the parser extension. Option D is the more precise description of the technical solution.
