C1000-175 Sample Questions

  1. Question 1

    Intermediate

    QRadar Architecture · Understand the logical components of QRadar

    A security architect is designing a distributed QRadar deployment for a multinational corporation. The organization requires long-term retention of event data for compliance but needs to minimize the load on the primary console during heavy search operations. Which architectural component should be introduced to scale storage and search performance without adding correlation load?

    Answer and explanation

    Correct answer: C

    Data Nodes are designed specifically to add storage and search processing power to a deployment. They attach to Event Processors or Flow Processors to distribute the data, allowing for faster search execution and extended retention without performing event correlation themselves.

  2. Question 2

    Beginner

    Events · Describe the processes of data ingestion

    While investigating a potential data exfiltration incident, an analyst observes that multiple similar events from the same source IP are occurring rapidly. QRadar is displaying these as a single line item in the Log Activity tab with a 'Count' greater than 1. What process is responsible for this behavior, and what is the primary benefit?

    Answer and explanation

    Correct answer: D

    Coalescing is the process where QRadar groups events that have the same properties (Source IP, Destination IP, Destination Port, Username, and Event ID) occurring within a short time window. This significantly reduces the number of records written to disk.

  3. Question 3

    Advanced

    Events · Event parsing

    A QRadar administrator is troubleshooting a custom log source that is not parsing correctly. The administrator opens the DSM Editor to adjust the parsing logic. Which of the following elements is primarily responsible for mapping a raw event to a specific QRadar Identifier (QID)?

    Answer and explanation

    Correct answer: D

    In the DSM Editor, the combination of the extracted 'Event ID' and 'Event Category' is used to map the incoming raw event to a specific QID in the QRadar taxonomy. If this mapping is incorrect or missing, the event appears as 'Unknown'.

  4. Question 4

    Intermediate

    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?

    Answer and explanation

    Correct answer: C

    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.

  5. Question 5

    Beginner

    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?

    Answer and explanation

    Correct answer: D

    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.

  6. Question 6

    Intermediate

    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?

    Answer and 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.
