At ValidExamDumps, we consistently monitor updates to the IBM C1000-156 exam questions by IBM. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the IBM Security QRadar SIEM V7.5 Administration exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by IBM in their IBM C1000-156 exam. These outdated questions lead to customers failing their IBM Security QRadar SIEM V7.5 Administration exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the IBM C1000-156 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
An administrator receives a file with all the vital assets in the company and wants to import this file into QRadar. How must this import file be formatted?
When importing vital asset information into IBM QRadar SIEM V7.5, the import file must be formatted as a CSV file with the following structure:
Format: CSV (Comma-Separated Values)
Fields: The required fields are IP address, Name, Weight, and Description.
IP address: The IP address of the asset.
Name: The name of the asset.
Weight: A numerical value representing the importance or criticality of the asset.
Description: A brief description of the asset.
This format ensures that QRadar can correctly parse and import the asset information, integrating it into its asset database for further analysis and correlation.
Reference IBM QRadar SIEM documentation provides guidelines on the required CSV format for importing asset information, detailing the necessary fields and their order.
A QRadar administrator creates a new saved search in QRadar.
Which option does the administrator enable to allow this search to be opened as the Log Activity tab is opened?
Similar to the previous question, when a QRadar administrator creates a new saved search and wants it to be the first search displayed upon opening the Log Activity tab, the correct option to enable is 'Set as Default.' Here's the detailed process:
Saved Search Creation: The administrator specifies the search parameters and criteria to create a new saved search.
Enabling Default Setting: By selecting the 'Set as Default' checkbox, the administrator ensures that this search will automatically run and display when the Log Activity tab is accessed.
Utility: This option is particularly useful for quickly accessing the most relevant data without needing to manually select and run the saved search each time.
Setting a default search helps maintain focus on critical security events by providing immediate access to predefined search results.

In a single domain QRadar deployment, which IP addresses are considered local?
In a single domain QRadar deployment, the IP addresses considered local are those that are defined in the network hierarchy. Here is a detailed explanation:
Network Hierarchy: QRadar uses a network hierarchy to define and manage IP addresses within the organization. This hierarchy allows QRadar to understand which IP addresses are part of the internal network and which are external.
Defining Local IP Addresses: Any IP address that is specified within the network hierarchy is considered local. This includes all the subnets and IP ranges that are part of the internal network.
Purpose: By defining the network hierarchy, QRadar can effectively differentiate between internal (local) and external (non-local) traffic, enabling more accurate detection and correlation of security events.
This approach helps in identifying suspicious activities by comparing the source and destination of traffic against the defined internal network.

From which two (2) resources can an administrator download QRadar security content?
Administrators can download QRadar security content from the following two resources:
QRadar Application Repository: This repository contains a wide range of applications, rules, reports, and other content specifically designed for QRadar.
IBM Security App Exchange: A platform where users can find and download security applications, including those for QRadar. It offers a variety of tools to extend and enhance the functionality of QRadar SIEM.
These resources provide curated and validated security content, ensuring that administrators have access to the latest and most effective tools for their security needs.
Reference IBM QRadar documentation and support resources detail the QRadar Application Repository and IBM Security App Exchange as primary sources for downloading and updating QRadar security content.
An administrator would like to optimize event and flow payload searches for log data that is stored for up to a month. What does an administrator need to do to achieve that requirement?
To optimize event and flow payload searches for log data stored for up to a month, an administrator should configure the retention period for payload indexes. Here's the process:
Retention Period Configuration: Set the retention period for payload indexes to match the desired data storage duration (e.g., one month).
Improved Search Efficiency: By configuring the retention period appropriately, QRadar ensures that the indexed data is efficiently searchable, improving performance during searches.
Index Management: Regularly manage and clean up indexes to maintain optimal system performance and storage utilization.
Reference The IBM QRadar SIEM administration guides provide instructions on configuring retention periods for various types of indexes, including payload indexes, to optimize search performance.
