C1000-162 IBM Security QRadar SIEM V7.5 Analysis Free Practice Exam Questions (2025 Updated)

Here's a breakdown of reference data collections in QRadar:

Primary Types:

Reference Set: Holds a list of unique values (e.g., IPs, domain names).

Reference Map: Maps a unique key to a single value.

Reference Map of Sets: Maps a unique key to a set of values.

Here's why "Am I Affected" is the most suitable answer among the given options:

Am I Affected (AIA): The "Am I Affected" feature on the IBM X-Force Exchange is designed specifically to help you determine if your systems have observed Indicators of Compromise (IOCs) related to a specific threat or campaign.

COVID-19 IOCs: If you have a set of IOCs (e.g., IP addresses, domain names, file hashes) associated with COVID-19-themed attacks, you can use the AIA feature to query QRadar and see if any were detected within your network.

Reasons Why Other Options Are Less Ideal:

TAXII Automatic Updates: This focuses on automatically pulling threat intelligence feeds into QRadar, not retrospective searches for past IOC presence.

STIX Bundle: A STIX bundle is a structured way to represent threat intelligence.expand_more It wouldn't directly tell you if those indicators have been seen in your QRadar data.

Threat Intelligence ATP: This likely refers to a broader threat intelligence platform, not a specific X-Force Exchange feature for checking QRadar data.

Understanding Time Series Charts in QRadar: Time series charts in IBM QRadar are used to plot data points over time. The axes of these charts are crucial as they define how data is represented and interpreted.

Types of Axis:

Linear Axis: A linear axis displays data points equally spaced along the axis. This is useful for evenly distributed data and straightforward trends.

Logarithmic (Log) Axis: A log axis represents data on a logarithmic scale. This is useful for data that spans several orders of magnitude and for visualizing exponential trends.

Selection of Axis Types: When creating time series charts in QRadar, users can choose from various axis types to best represent their data. The linear and log axes are commonly used due to their effectiveness in displaying a wide range of data types and trends.

Reference Confirmation: According to IBM QRadar documentation, the linear and logarithmic axes are supported for time series charts, making them the correct choices.

References:

IBM QRadar documentation on charting options and axis types confirms the availability of linear and logarithmic axes.

Understanding Reference Data Collections in QRadar: In IBM QRadar, reference data collections are used to store data that can be reused across various rules, searches, and reports. Each type of reference data collection has a specific use case and structure.

Types of Reference Data Collections:

Reference Map: Stores key-value pairs where each key is unique and maps to a specific value.

Reference List: Stores a list of values without any keys.

Reference Table: Stores multiple key-value pairs where each key can have multiple values.

Reference Set: Stores a set of unique values without any keys.

Use Case for Reference Map: When you need to correlate a unique key to a specific value, a reference map is the appropriate data structure. It allows for efficient lookups and associations between keys and their corresponding values.

Reference Confirmation: According to IBM QRadar documentation, a reference map is explicitly designed to correlate unique keys to values, making it the correct choice for such requirements.

References:

IBM QRadar documentation on reference data collections confirms the use of a reference map for correlating unique keys to values.

When investigating an offense in QRadar, finding the number of flows or events associated with it can be achieved through the "List Events/Flows" option. This functionality allows analysts to view a detailed list of all the individual events and flows that are related to a specific offense, offering insights into the nature and scope of the activities involved. By examining this list, analysts can better understand the context of the offense, including the types of network traffic and system actions that triggered the security alerts, facilitating a more informed investigation process.

When searching for all events related to "Login Failure," a security analyst should use the Event Name parameter to filter the events. This allows the analyst to specifically target events with descriptions such as "Database Login Failure," which indicates that a database login attempt failed​​​​.

Pie Chart Logic: Pie charts represent proportions of a whole.expand_more QRadar Pulse supports the following aggregations suitable for this:

Total (Sum): Calculates the sum of a selected field's values, displaying each slice relative to the whole.

First: Takes the first value encountered in a field, useful for categorical data to show initial distribution.

Offense Summary Window: The Offense Summary window provides detailed information about a specific offense.

Display Menu: Within this window, the "Display" menu offers options to customize what information is shown.

Rules Option: Selecting "Display > Rules" will reveal a list of rules that contributed to the chained offense sequence.

For pie charts in the Pulse app of QRadar, the available aggregation types include "Total" and "Average." These aggregation types allow for the representation of data in a manner that summarizes the total sum of the data points or their average value, respectively, providing insightful and concise visualizations of the data within the Pulse app dashboards. This information is implied from the general capabilities of dashboard items in QRadar, as detailed in the provided documentation, which typically includes such aggregation options for data visualization​​.

The Application Overview dashboard in QRadar includes various default items1. Two of these items are Top Applications (Total Bytes) and Outbound Traffic by Country (Total Bytes)1.

Default dashboards - IBM Documentation

According to the IBM Security QRadar SIEM V7.5 documentation, the Application Overview dashboard by default includes items such as "Inbound Traffic by Country (Total Bytes)," "Outbound Traffic by Country (Total Bytes)," and "Top Applications (Total Bytes)" among others. This confirms that options C and D are displayed by default on the Application Overview dashboard​​.

In QRadar, when performing a search in the My Offenses or All Offenses tabs, valid values for the Offense Type field include "Any" and "Source IP". "Any" searches all offense sources, while "Source IP" allows for searching offenses with a specific source IP address​​.

Understanding Offense Parameters in QRadar: In IBM QRadar, offenses are evaluated and prioritized based on several parameters that determine the significance and potential impact of the security incident.

Key Parameters:

Relevance: Indicates how relevant the event is to the organization's environment.

Severity: Represents the potential damage or impact the event could have on the system.

Credibility: Reflects the likelihood that the event represents a true security incident.

Magnitude Rating Calculation: The magnitude rating is a composite score that is calculated using the relevance, severity, and credibility of an offense. This rating helps security analysts prioritize incidents based on their potential threat level.

Reference Confirmation: According to IBM QRadar documentation, the magnitude rating is the parameter that is derived from the relevance, severity, and credibility of an offense.

References:

IBM QRadar documentation on offense management and parameters confirms the calculation of the magnitude rating based on relevance, severity, and credibility .

Context Menu: Right-clicking on an IP address in the Offense Summary window offers quick investigation actions.

IP-Related Tools: WHOIS and DNS Lookups are essential tools for:

WHOIS: Retrieving IP registration information (owner, contact details, etc.). DNS: Resolving domain names associated with the IP.

Dashboard Data Refresh: Most widgets on QRadar dashboards typically refresh the displayed data every minute by default.

Customization: In some cases, you might be able to configure this refresh interval depending on the widget type.

Within IBM Security QRadar's Ariel Query Language (AQL), functions play a crucial role in manipulating data, performing calculations, and formatting results for more insightful analysis. Among the options provided, "LOWER" (C) and "STRLEN" (D) are valid AQL functions used for formatting and calculations, respectively. The "LOWER" function is used to convert a string to lowercase, which can be useful for case-insensitive comparisons or data normalization. The "STRLEN" function calculates the length of a string, providing valuable information about the data content, such as detecting unusually long or short values that might indicate anomalies or issues within the event or flow data .

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​​.

By default, QRadar stores payload indexes for a duration of 30 days. This retention period is configurable, allowing administrators to adjust how long specific data is retained based on their requirements​​.

X-Force Exchange: The primary repository for contributed QRadar content, including compliance-focused content packs.

HIPAA Packs: Likely contain:

Predefined searches: Relevant to HIPAA monitoring and auditing

Reports: To generate structured documentation for compliance

Custom Rules: To detect potential HIPAA-related violations

Custom properties: To enhance event/flow data for HIPAA context

Other Options (less suitable):

Use Case Manager: Broader purpose, might include HIPAA use cases

Pulse App: Primarily dashboard oriented, not focused on content distribution

IBM Fix Central: Focuses on software fixes, not compliance content
