C1000-175 Sample Questions & Answers
SIEM fundamentals, QRadar's architecture, event ingestion, and writing rules and building blocks carry equal top weight, alongside the user interface, app extensions, flow sources, offense handling, AQL search, asset data, tuning, and user roles.

- Question 1Intermediate
Events · Describe the processes of data ingestion
Review the following diagram of the QRadar event pipeline:
flowchart LR A[Event Collection] --> B[Event Parsing/Normalization] B --> C[Traffic Analysis/Autodetection] C --> D[Coalescing] D --> E[?] E --> F[Magistrate/CRE]Which component or process correctly fills the position labeled 'E' in the pipeline before the data is sent to the Magistrate for correlation?
Show answer & explanation
Correct answer: B
In the event pipeline, after coalescing, events are processed by the Custom Rule Engine (CRE) on the Event Processor. The CRE evaluates events against rules. If a rule triggers, it may generate an offense which is then managed by the Magistrate. The diagram shows the flow towards the Magistrate/CRE complex; technically the CRE processes it before the Magistrate creates the offense.
- Question 2Beginner
Reporting and Dashboards · Manage reports
A security analyst needs to create a report that shows the top 10 source IPs generating 'Login Failed' events over the last 24 hours. Which QRadar tab is the primary location for creating and scheduling this report?
Show answer & explanation
Correct answer: C
The Reports tab is specifically designed for creating, scheduling, and managing reports. While searches start in Log Activity, the actual report definition and scheduling happen in the Reports tab.
- Question 3Intermediate
Rules and Building Blocks · Understand rules tests
When defining a new custom rule in QRadar, an administrator wants to ensure that the rule only triggers if a specific sequence of events occurs within a 5-minute window. Which rule test logic operator is required to define this sequence?
Show answer & explanation
Correct answer: B
To detect a specific sequence, the rule must use the 'and when these events occur in order' test options. This allows the administrator to define the exact flow of events (e.g., Event A followed by Event B) required to trigger the rule.
- Question 4Intermediate
Flows · Explain the basic use case for QNI versus QIF
An organization is using QRadar Network Insights (QNI) to inspect traffic. The security team needs to identify data exfiltration attempts where sensitive documents are being transferred. They require visibility into the actual file content, not just the metadata. Which QRadar component is best suited for deep forensic reconstruction of the session to view the transferred files?
Show answer & explanation
Correct answer: B
While QNI provides deep packet inspection and metadata extraction (Layer 7 visibility), QRadar Incident Forensics (QIF) is designed for full packet capture and session reconstruction, allowing analysts to replay sessions and view/recover actual transferred files.
- Question 5Intermediate
Working with Offenses · Describe the basic offense lifecycle
A SOC analyst is reviewing an offense that has a high Magnitude. The Magnitude is calculated based on three weighted characteristics. If the 'Severity' is high but the 'Credibility' is low, how does this affect the overall Magnitude?
Show answer & explanation
Correct answer: B
Magnitude is a calculated value based on Severity (how bad is the attack?), Credibility (how reliable is the source?), and Relevance (does it impact a critical asset?). A low Credibility score significantly drags down the overall Magnitude, even if Severity is high.
- Question 6Advanced
Search, Filtering, and AQL · Utilize different search types
Which AQL query syntax is correct for selecting the source IP and the count of events, grouped by source IP, for the last 10 minutes?
Show answer & explanation
Correct answer: A
This is the correct AQL syntax. It selects the field 'sourceip' and the aggregate function 'COUNT(*)', specifies the database 'FROM events', groups the results 'GROUP BY sourceip', and sets the time range 'LAST 10 MINUTES'.
