Question 1

What QRadar application can help you ensure that IBM GRadar is optimally configured to detect threats accurately throughout the attack chain?



Answer : D

The IBM QRadar Use Case Manager application assists in tuning QRadar to ensure it is optimally configured for accurate threat detection throughout the attack chain. This application provides guided tips to help administrators adjust configurations, making QRadar more effective in identifying and mitigating security threats. The QRadar Use Case Manager plays a significant role in maintaining the effectiveness of the QRadar deployment.


Question 2

Which kind of information do log sources provide?



Answer : A


Question 3

The Use Case Manager app has an option to see MITRE heat map.

Which two (2) factors are responsible for the different colors in MITRE heat map?



Answer : C, D

The MITRE heat map in the Use Case Manager app within QRadar uses several factors to determine the colors displayed, among which the number of rules mapped to MITRE ATT&CK tactics and techniques and the level of mapping confidence are crucial. These factors help visualize the coverage and reliability of rule mappings against the comprehensive MITRE ATT&CK framework, aiding in the identification of potential gaps or areas for improvement in threat detection capabilities.


Question 4

On which lab can an analyst perform a "Flow Bias" Quick Search?



Answer : D

A 'Flow Bias' Quick Search can be performed from the Network Activity tab in QRadar, providing insights into network flows and potential anomalies or biases in the traffic patterns.


Question 5

How can adding indexed properties to QRadar improve the efficiency of searches?



Answer : A

Adding indexed properties to QRadar can significantly improve the efficiency of searches by reducing the size of the data set required to locate matches for non-indexed search values. Indexing creates references to unique terms in the data and their locations, which means that the search engine can filter the data set by indexed properties first, eliminating irrelevant portions of the data set and thereby reducing the overall volume of data that needs to be searched.


Question 6

When examining lime fields on Event Information, which one represents the time QRadar received the raw event?



Answer : C

The 'Start Time' timestamp represents when an event is received by a QRadar Event Collector, marking the moment QRadar first becomes aware of the event. This is crucial for understanding the timing of event processing and potential delays in the event pipeline.


Question 7

Which type of rule should you use to test events or (lows for activities that are greater than or less than a specified range?



Answer : D

Threshold rules in QRadar are designed to test events or flows for activities that are greater than or less than a specified range. These rules are particularly useful for detecting significant changes such as bandwidth usage variations, failed services, changes in the number of connected users, and large outbound data transfers. By setting acceptable limits within threshold rules, administrators can effectively monitor for and respond to abnormal activities within the network.
