Objective 2.3
Cybersecurity Defense ArchitectIdentify high value / high signal / high noise data sources (e.g. Windows process vs EDR process flow, or network/VPC flow vs packet capture) and how they support security operations use cases
Objective 2.3 sits in Security Data Management, which carries 20% of the Cybersecurity Defense Architect exam. The questions below are original, written from the official objective title above, and each explanation cites the Splunk page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An engineer weighs packet capture against log collection. What advantage does Splunk document for packet data?
Correct.
Checked against help.splunk.com, August 2026Concept
Packet data is expensive and answers questions logs cannot. That trade is the whole argument for capturing it in some places and not others.
Why D
Splunk documents that packet capture data contains security-relevant information not typically collected in log files.

Splunk Docs: Protocol Intelligence dashboards, checked August 2026Packet capture data contains security-relevant information not typically collected in log files. Integrating network protocol data provides a rich source of additional context when detecting, monitoring, and responding to security related threats.
Now you: objective 2.3 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 2
An engineer must choose between the Network Traffic and Intrusion Detection models for a firewall feed. Which basis does Splunk document for Network Traffic?
Sample question 2 of 2
An engineer asks how Intrusion Detection differs in when traffic is denied. What does Splunk document?

More objectives in Security Data Management
- 2.1 Explain how to develop and implement integration strategies for data-driven security operations
- 2.2 Identify data sources critical to cybersecurity operations, such as event sources, identity directories, asset management systems, and vulnerability - assessments. This can include non-security data sources, eg. observability tools
- 2.4 Identify strategies to monitor an environment that requires nonstandard or out-of-band instrumentation and sensors, e.g. legacy data sources, OT/IC infrastructure environments
- 2.5 Develop a data lifecycle management strategy, including retention, storage tiering, summarization, data residency, and access control
- 2.6 Describe the value of data normalization in order to support integration into cybersecurity defense programs, such as security monitoring and threat hunting, e.g. with CIM, CEF
- 2.7 Implement security analytics strategies beyond traditional SIEM such as advanced techniques like data science, machine learning, behavioral analysis, and AI
- 2.8 Explain how cybersecurity defense data architectures scale using technologies and capabilities such as data mesh, data lakes, message bus, message routing, and federated search
