Objective 2.8
Cybersecurity Defense ArchitectExplain how cybersecurity defense data architectures scale using technologies and capabilities such as data mesh, data lakes, message bus, message routing, and federated search
Objective 2.8 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 asks what federated search offers a defence programme. What does Splunk document?
Correct.
Checked against help.splunk.com, August 2026Concept
Searching where the data already sits avoids moving it at all. That matters most where moving it would cross a residency boundary or a cost line.
Why A
Splunk documents federated search as a tool that allows you to search remote datasets throughout your data ecosystem from a single Splunk platform search interface.

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
- 2.3 Identify 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
- 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
