Free IBM C1000-156 Exam Actual Questions

Note: Premium Questions for C1000-156 were last updated On Apr. 17, 2025 (see below)

Question #1

What is the main reason for tuning a building block?

Reveal Solution Hide Solution
Correct Answer: B

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.


Question #2

When creating an identity exclusion search, what time range do you select?

Reveal Solution Hide Solution
Correct Answer: B

When creating an identity exclusion search in IBM QRadar SIEM V7.5, the time range selected is 'Real time (streaming).' This setting ensures that the search continuously monitors and excludes identities in real-time as data is ingested. Here's the process:

Real-time Monitoring: Continuously updates the search results based on incoming data, providing immediate exclusion of specified identities.

Streaming Data: Processes data in a live stream, ensuring that the exclusion criteria are applied instantaneously as new events occur.

Reference The setup and configuration of identity exclusion searches are detailed in the QRadar SIEM administration guides, highlighting the importance of real-time streaming for effective identity management.


Question #3

In a single domain QRadar deployment, which IP addresses are considered local?

Reveal Solution Hide Solution
Correct Answer: C

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.

Question #4

How can you configure a log source to provide events to different domains?

Reveal Solution Hide Solution
Correct Answer: C

To configure a log source in IBM QRadar SIEM V7.5 to provide events to different domains, administrators can use custom properties. Here's how it works:

Custom Properties: Create and configure custom properties to tag events with specific domain information.

Assigning Events: When events are ingested from a log source, these custom properties can be used to dynamically assign events to different domains based on predefined criteria.

Domain Management: This approach allows flexibility in managing and segregating data from a single log source across multiple domains, ensuring that each domain receives the relevant events.

Reference The configuration of custom properties for domain assignment is detailed in the QRadar SIEM administration guides, providing step-by-step instructions for setting up and using custom properties for domain management.


Question #5

What is the most restrictive permissions a user needs in order to see all of the events from a particular log source in the Log Activity tab?

Reveal Solution Hide Solution
Correct Answer: B

To see all of the events from a particular log source in the Log Activity tab, a user must have the appropriate permissions set in their security profile. The most restrictive permissions needed are:

Security Profile Inclusion: The log source must be included in the user's security profile. This means the user must have explicit permission to access events from this log source.

Permissions to Networks and Log Sources: The user's security profile must also include permissions to both Networks and Log Sources. This ensures the user has the necessary access to view events related to the specified log source within the network context.

These permissions are crucial to control and restrict access, ensuring users can only view data they are authorized to see while maintaining security and privacy within the system.
