IBM Certification Security QRadar, Associate Analyst 2 — Questions and Answers
Question 1: Which QRadar component is responsible for collecting raw event data from log sources and normalizing it into a standard format?
- Event Collector (Correct answer)
- Flow Processor
- Magistrate
- Ariel Query Engine
Correct answer: Event Collector
The Event Collector gathers raw events from log sources and passes them to the Event Processor for normalization via DSMs.
Question 2: In QRadar, what does AQL stand for and what is its primary use?
- Ariel Query Language, used to search event and flow data (Correct answer)
- Advanced Query Logic, used to create correlation rules
- Automated Query Listener, used to poll log sources
- Ariel Queue Language, used to manage data pipelines
Correct answer: Ariel Query Language, used to search event and flow data
AQL (Ariel Query Language) is QRadar's SQL-like language used to query the Ariel database for events and flows.
Question 3: What is the purpose of a DSM (Device Support Module) in IBM QRadar?
- It parses and normalizes raw log data from specific devices into QRadar's standard event format (Correct answer)
- It monitors disk space on QRadar appliances
- It manages user authentication and access controls
- It generates compliance reports for auditors
Correct answer: It parses and normalizes raw log data from specific devices into QRadar's standard event format
A DSM maps raw log messages from a specific device type into QRadar's normalized event fields, enabling correlation.
Question 4: An analyst notices a QRadar offense has a magnitude of 8. What does magnitude primarily reflect?
- The overall severity combining relevance, credibility, and severity scores (Correct answer)
- The number of unique source IPs involved in the offense
- The total byte count of network flows associated with the offense
- The number of rules that triggered to create the offense
Correct answer: The overall severity combining relevance, credibility, and severity scores
Offense magnitude is a composite score (1–10) calculated from relevance, credibility, and severity of the contributing events.
Question 5: Which QRadar feature allows you to store a list of values (such as known malicious IPs) that can be referenced by rules and searches?
- Reference Set (Correct answer)
- Custom Property
- Building Block
- Log Source Extension
Correct answer: Reference Set
Reference Sets store collections of values (IPs, usernames, etc.) that rules and searches can dynamically look up to trigger or filter events.
Question 6: In QRadar, what is the role of the 'Magistrate' component?
- It applies rules against normalized events and flows to create or update offenses (Correct answer)
- It stores raw event data in the Ariel database
- It collects NetFlow data from network devices
- It manages the QRadar console web interface
Correct answer: It applies rules against normalized events and flows to create or update offenses
The Magistrate evaluates correlation rules against incoming events and flows and is responsible for generating and managing offenses.
Question 7: What does it mean when a QRadar log source is in 'Parsing Failure' status?
- QRadar is receiving events from the device but cannot parse them with the assigned DSM (Correct answer)
- The log source device is offline and not sending any data
- QRadar has exceeded its event-per-second license limit
- The log source was manually disabled by an administrator
Correct answer: QRadar is receiving events from the device but cannot parse them with the assigned DSM
A Parsing Failure status means events are arriving but the DSM cannot correctly interpret the log format, often due to a custom or unsupported format.
