When viewing or exporting event search results from the IBM QRadar Log Activity tab, the default columns are configured to provide a concise, high-level summary for an initial investigation. The columns listed in option A—Log Source, Event Count, High Level Category, and Related Offense—are fundamental to this initial analysis. Log Source identifies the origin, Event Count shows the frequency (especially in grouped views), High Level Category classifies the event type, and the Related Offense column indicates if the event is correlated into a security offense. While the complete default view includes other columns, this combination represents the most accurate and functionally relevant set among the choices.

B. 'Application' and 'Username' are not default columns. They are valuable for specific investigations but must be manually added to the view as they are not universally present in all log types.

C. 'Username' and 'Source Port' are not part of the default column set. These are specific event properties that an administrator would typically add for a more granular investigation.

D. 'Protocol', 'Storage Time', 'Destination Port', and 'Source Port' are all non-default columns that provide specific network or metadata details and are not included in the default summary view.

1. IBM QRadar SIEM User Guide (Version 7.5.0), Chapter 6: "Investigating events", Section: "Event investigation columns", Page 62. This section details the columns available in the Log Activity tab, noting that the default display includes columns "commonly used for event investigations," such as Log Source, Event Count, and category information. The presence of an offense indicator is also a standard UI element.

2. IBM Security Learning Academy, Course BQ103G: IBM QRadar SIEM Foundations, Unit 5: "Investigating an Offense Triggered by Events". The lab exercises and user interface demonstrations in this official course consistently show Log Source, Event Count, and Category information as primary columns in the default Log Activity view. The link between events and offenses is a core concept, making the Related Offense information a key default element.

To configure IBM QRadar for automatic geographic data updates from MaxMind, the geoipupdate.sh script is used. This script reads its configuration from the /opt/qradar/conf/geoipupdate.conf file. According to the official IBM QRadar documentation, this configuration file requires two specific credentials from the MaxMind account: the ACCOUNTID (corresponding to Account/User ID) and the LICENSEKEY. These two values are used to authenticate with the MaxMind servers and authorize the download of the GeoIP2 or GeoLite2 database files.

B. API key: The MaxMind geoipupdate service, used by QRadar, specifically requires a "License Key" for authentication, not a generic "API key".

D. MaxMind username: Authentication is not based on a user's login name but on the numeric Account ID assigned by MaxMind.

E. API password: The authentication mechanism for the geoipupdate service does not use a password; it relies on the combination of the Account ID and License Key.

1. IBM QRadar Administration Guide (Version 7.5.0): In the section "Configuring automatic updates for geographic data," the procedure explicitly states: "In the /opt/qradar/conf/geoipupdate.conf file, set the values for ACCOUNTID and LICENSEKEY to the values that you get from your MaxMind account." This directly supports the requirement for both an Account ID and a License Key.

2. MaxMind Developer Documentation: The official documentation for the geoipupdate program, which QRadar utilizes, specifies the required credentials. In the "Download and Update Databases with geoipupdate" guide, it states, "You will need your Account ID and a License Key to use geoipupdate." The sample configuration file shown also includes the fields AccountId and LicenseKey. (Reference: https://dev.maxmind.com/geoip/geoipupdate/)

The recon connect command is a specific utility within the IBM QRadar App Framework command-line interface (CLI). Its designated purpose is to establish a connection to a running application container and execute a command within it. The container can be targeted using its unique application ID or by specifying its workload, service, and container name, directly matching the functionality described in the question.

A. ifconfig -a: This is a standard Linux command used to display information about network interfaces. It does not interact with QRadar application containers.

B. recon ps: This command lists the running QRadar application containers, similar to the docker ps command, but it does not execute commands inside them.

D. yum info: This is a standard Linux command for the YUM package manager, used to display information about software packages. It is unrelated to QRadar app management.

1. IBM QRadar SIEM Administration and Configuration Guide (V7.5.0):

Section: "Managing apps by using the recon command-line utility"

Content: This section explicitly details the usage of the recon tool. It states, "Use the connect command to run a specific command inside of a specific container, when given an app ID, or a combination of workload, service, and container." This directly confirms that recon connect is the correct command for the described task. The guide also describes recon ps as the command to "list all of the running containers on the system," differentiating its function from recon connect. (This information is found in the official product documentation for QRadar V7.5.0).

2. IBM Security Learning Academy - Course: IBM Security QRadar SIEM 7.5 Administration (BQ106G):

Module: "QRadar App Framework Administration"

Content: The courseware for QRadar administration covers command-line tools for troubleshooting and managing applications. The recon utility is highlighted, with recon connect being presented as the primary method for interacting with the shell of a running app container to perform diagnostics or execute commands.

The License Pool Management section in the QRadar Admin tab is the designated interface for managing and monitoring license allocations across all hosts in a deployment. This screen provides a comprehensive table view of each host's license capacity, current usage, and other key metrics. The "License Giveback" rate, which indicates the amount of unused license capacity a host is returning to the shared pool, is explicitly displayed as a column in this table for each applicable host.

A. The "System Settings" section contains general system-wide configurations, but the specific, detailed license allocation and giveback metrics are located in the dedicated "License Pool Management" area.

B. Ariel Query Language (AQL) is used for searching and analyzing event and flow data stored in the Ariel database, not for querying internal system configuration or license metrics.

D. The Log Activity tab is for viewing and analyzing security events. While license-related system notifications might appear here, it is not the correct tool for monitoring a specific metric like the giveback rate.

1. IBM QRadar SIEM Administration Guide: In the section on license management, the guide details the "License Pool Management" window. It states, "Use the License Pool Management window to manage the EPS and FPM license allocations for each host in your deployment." The interface described explicitly includes columns for monitoring license giveback. (Reference: IBM Documentation, QRadar SIEM, Administering QRadar > System settings > License management > License pool management).

2. IBM QRadar SIEM Core Functionality Guide: This guide explains the concept of shared license pools and the giveback feature. It directs administrators to the Admin tab and the License Pool Management icon to view and configure these settings, confirming it as the location to see the giveback status and rate. (Reference: IBM Documentation, QRadar SIEM, Core Functionality > Data collection > Event and flow processing > Shared license pools).

The IBM QRadar Server Discovery function is designed to automatically identify servers and their roles (e.g., web server, mail server, DNS server) on a network. This process involves analyzing network traffic and other data sources. All the information gathered about these discovered servers, including their services, open ports, and server classification, is populated into and stored within the Asset Profile Database. This database acts as the central repository for comprehensive information about all known assets on the network, which is essential for correlation rules, reporting, and incident investigation.

A. Flow profile database: The flow database stores raw network session data (flows), which is a source for discovery, but it is not the profile database where consolidated asset and server information is stored.

B. Network profile database: This is a generic term. The specific and correct name for the database that stores host and server information in QRadar is the Asset Profile Database.

C. Domain profile database: This database stores information related to network domains and their assets. While related, it is a component of the broader Asset Profile Database, which is the primary answer.
