IBM Security QRadar SIEM V7.5 Administration Sample Questions (Q60-Q65):

NEW QUESTION # 60
Which is the default port for the first NetFlow flow source that is configured in QRadar?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A

Explanation:
The default port for the first NetFlow flow source configured in QRadar is 2055. Here's a detailed explanation:
NetFlow Flow Sources: NetFlow is a network protocol developed by Cisco for collecting IP traffic information. QRadar can be configured to receive NetFlow data to monitor and analyze network traffic.
Default Port: When setting up the first NetFlow flow source in QRadar, the system uses port 2055 by default. This is a standard port commonly used for NetFlow traffic.
Configuration: During the configuration process, this default port can be used to receive data from devices that export NetFlow data, such as routers and switches.
Using port 2055 helps standardize the setup process and ensures compatibility with most NetFlow-enabled devices.

NEW QUESTION # 61
You analyzed network flows and decided that you want to track any network bandwidth violations by any application that comes from your network source. You want to report on all applications that create traffic and the amount of data (total bytes) from each IP. You want to store the IP address, the application, and the amount of data in the reference data collection.
What type of reference data collection must you create to support this use case?

  • A. Reference map of sets
  • B. Reference map of maps
  • C. Reference set
  • D. Reference map

Answer: D

Explanation:
To track network bandwidth violations by any application coming from your network source and report on all applications that create traffic along with the amount of data from each IP address, you need to store the IP address, the application, and the amount of data in a reference data collection. The appropriate type of reference data collection for this use case is a "Reference map." Here is why:
Reference Map: A reference map allows you to store key-value pairs where each key is unique. In this context, the key can be the combination of the IP address and the application, and the value can be the amount of data (total bytes).
Data Structure: This structure enables efficient lookups and updates, which is ideal for tracking and reporting bandwidth usage per application per IP address.
Use Case Suitability: The reference map is suitable for scenarios where you need to store and retrieve values based on a specific key, and it supports storing complex data structures efficiently.
This type of reference data collection supports the use case by allowing the storage and retrieval of detailed network traffic information per application and IP address.

NEW QUESTION # 62
Which user role is defined by default in QRadar?

  • A. QRadar Managers
  • B. WinCollect
  • C. Event and Logs
  • D. QRadar Users

Answer: D

Explanation:
The default user role defined in QRadar is "QRadar Users". Here's a detailed explanation:
User Roles in QRadar: QRadar has a role-based access control system to manage user permissions and access levels. This ensures that users can only access and perform actions within their assigned roles.
Default Role - QRadar Users: The "QRadar Users" role is the default role assigned to new users. This role typically includes basic permissions needed to access and use QRadar features without administrative privileges.
Permissions: Users with the "QRadar Users" role can view and analyze security data, but they might have limited access to configuration settings and administrative functions.
Assigning default roles helps streamline user management and ensures that new users have the necessary access to perform their tasks.

NEW QUESTION # 63
Before configuring a WinCollect log source, which two ports does a QRadar administrator ensure are open?

  • A. 514 and 8413
  • B. 8080 and 8413
  • C. 443 and 8413
  • D. 445 and 8413

Answer: A


NEW QUESTION # 64
What is the main reason for tuning a building block?

  • A. Reducing the number of false positives
  • B. Properly documenting the building block for future administrators
  • C. Increasing the performance of the ecs-ec-ingress service
  • D. Reducing EPS usage

Answer: A

Explanation:
Tuning a building block in IBM QRadar SIEM V7.5 is primarily aimed at reducing the number of false positives. This process involves adjusting the rules and logic within the building block to better differentiate between normal and suspicious activity. Here's the detailed explanation:
False Positives: High numbers of false positives can overwhelm analysts and obscure genuine threats. Tuning helps in refining detection criteria to reduce these false alarms.
Rule Adjustments: Modifying the thresholds, conditions, and filters within the building block rules to ensure they more accurately reflect the environment's typical behavior.
Improved Accuracy: Enhanced precision in detecting true security incidents, thus improving the overall effectiveness of the SIEM solution.
Reference
IBM QRadar SIEM administration guides and best practice documents emphasize the importance of tuning to minimize false positives, ensuring more actionable alerts.
