Question 1

How can an administrator configure a rule response to add event data to a reference set?

AWrite a custom script.

BUse AQL functions.

CUse the 'add the following data to a reference set' rule test.

DUse the 'add to reference set' rule response.

Answer : D

Administrators can configure a rule response in QRadar to add event data to a reference set by using the 'add to reference set' rule response. This is a predefined response action in QRadar that allows specific event data to be added to a reference set when the rule conditions are met.

Navigate to the 'Offenses' tab in the QRadar console.

Select 'Rules' from the navigation pane.

Create a new rule or edit an existing rule.

In the 'Rule Response' section, add a new response.

Select the 'Add to Reference Set' response.

Specify the reference set and the data to be added.

Save and deploy the rule.

Question 2

Which is a benefit of a lazy search?

AGetting results that are limited to a specific range

BProviding every result no matter the quantity of the search results

CFinding lOCs quickly

DSearching across domains for any configured user

Answer : A

A lazy search in IBM QRadar SIEM V7.5 is designed to optimize the performance of search queries by limiting the amount of data retrieved and processed at any given time. This is particularly beneficial in environments with large datasets. Here's a detailed explanation:

Limited Results: Lazy searches limit the search results to a specific range, allowing users to get manageable chunks of data without overwhelming the system.

Performance Optimization: By reducing the amount of data processed in a single search, lazy searches improve query performance and reduce resource usage.

Incremental Data Retrieval: Users can incrementally retrieve more data as needed, making it easier to handle and analyze large datasets without performance degradation.

Reference The functionality and benefits of lazy searches are detailed in the IBM QRadar SIEM V7.5 user guides, which explain how to configure and use lazy searches for efficient data retrieval and analysis.

Question 3

What Iwo things are required for an administrator to deobfuscate data in QRadar?

APublic key and the password for the key that is used to obfuscate data

BPrivate key and the password for the key that is used to obfuscate data

CPrivate key and public key that is used to obfuscate data

DPublic key and the password for the private key that is used to obfuscate data

Answer : B

In IBM QRadar SIEM V7.5, to deobfuscate data, an administrator requires two critical components:

Private Key: This key is used to decrypt the data that was originally obfuscated. The private key must match the public key used during the obfuscation process.

Password for the Private Key: This password is necessary to unlock the private key, allowing the decryption process to proceed.

The process involves using the private key in conjunction with its password to reverse the obfuscation, ensuring that the data is securely accessed only by authorized personnel.

Reference The requirement for the private key and its password for deobfuscating data is detailed in the IBM QRadar SIEM administration and security guides, ensuring that the process adheres to best practices for data security.

Question 4

What are some of the supported custom property expression types in QRadar?

ARegex, RDBMS, LEEF

BRegex, JSON, LEEF

CRDBMS, JSON, HTML

DRegex. JSON, HTML

Answer : B

IBM QRadar SIEM supports various types of custom property expressions to allow users to extract and parse data from logs in flexible and powerful ways. Among the supported custom property expression types, Regex, JSON, and LEEF are frequently utilized:

Regex (Regular Expressions): Regular expressions are a powerful tool used for pattern matching and extraction in text. In QRadar, regex can be used to create custom properties that parse specific patterns from log data, allowing for detailed and precise data extraction.

JSON (JavaScript Object Notation): JSON is a widely used data interchange format that is lightweight and easy to read and write. QRadar supports JSON expressions to parse and extract structured data from logs formatted in JSON.

LEEF (Log Event Extended Format): LEEF is a log format used by various devices to structure log data in a consistent manner. QRadar can utilize LEEF expressions to extract data from logs that use this format.

These types of expressions enhance QRadar's ability to handle diverse log formats and enable more accurate and efficient data analysis.

Question 5

When adjusting a custom email template, which two elements do you edit to include the customizations?

A<heading> <text>

B<heading> <body>

C<subject> <text>

D<subject> <body>

Answer : D

When adjusting a custom email template in IBM QRadar SIEM V7.5, the two elements that need to be edited to include customizations are:

<subject>: This element defines the subject line of the email, which can be customized to provide a clear and relevant description of the email's content.

<body>: This element contains the main content of the email. Customizing the body allows administrators to include specific information, formatting, and messages relevant to the recipient.

Customizing these elements ensures that the email notifications are informative and tailored to the needs of the recipients.

Reference The QRadar SIEM user and configuration guides provide instructions on customizing email templates, highlighting the <subject> and <body> elements as key areas for customization.

Question 6

When configuring a log source, which protocols are used when receiving data into the event ingress component?

ASFTR HTTP Receiver, SNMP

BSyslog, HTTP Receiver, SNMP

CSyslog, FTP Receiver, SNMP

DSyslog, HTTP Receiver, JDBC

Answer : B

When configuring a log source in IBM QRadar SIEM V7.5, the protocols used to receive data into the event ingress component are critical for ensuring proper data collection and analysis. The main protocols that are supported for this purpose are:

Syslog: A widely used protocol for message logging, supported by many network devices and servers.

HTTP Receiver: Allows QRadar to receive logs via HTTP POST requests, enabling integration with various web services and applications.

SNMP (Simple Network Management Protocol): Used for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.

Reference IBM QRadar SIEM documentation and product guides confirm that these are the supported protocols for receiving data into the event ingress component. The specific details on protocol support can be found in the QRadar SIEM administration and configuration manuals.

Question 7

In which QRadar section can the administrator view the license giveback rate?

AAdmin tab > system settings

BLog Activity tab > AQL query in the Advanced Search 'select LicenseGiveback from license'

CAdmin tab > License pool management

DLog Activity tab by searching for the term 'giveback' in the Quick Filter

Answer : C

In IBM QRadar SIEM V7.5, the license giveback rate can be viewed in the License Pool Management section. Here's the step-by-step process:

Access Admin Tab: The administrator needs to navigate to the Admin tab in the QRadar GUI.

License Pool Management: Under the Admin tab, there is an option for License Pool Management.

View License Giveback Rate: Within the License Pool Management section, the administrator can view details about license usage, including the giveback rate.

Reference The QRadar SIEM administration guide provides detailed steps on accessing and managing license information, including the giveback rate, under the Admin tab.
