Splunk Updated SPLK-5001 Exam Questions and Answers by alastair

When querying accelerated data models using thetstatscommand in Splunk, the argumentsummariesonly=trueensures the search uses only the accelerated summary data, not the raw events. This parameter restricts the search to the precomputed, optimized data summaries, providing much faster query performance.

summariesonly=trueexplicitly directs Splunk to use accelerated data, bypassing slower raw data scans.

Other options like accelerate=true or dataset=accelerated are invalid or misused in this context.

datamodel=accelerated is also incorrect since the datamodel argument requires the name of the data model, not a mode.

TheSplunk tstats command documentationandCybersecurity Defense Analyst Study Guideboth specify that summariesonly=true is critical for efficient querying of accelerated data models such as the Network Traffic Data Model.

The correct order of the examples listed corresponds toTactic, Technique, Procedurein the TTP framework:

Tactic:The high-level goal or objective an adversary tries to accomplish. "Extend movement" (likely meant as "Lateral movement") or "Exploiting a remote service" are tactics that describewhatthe adversary wants to do.

Technique:The general method or approach used to achieve the tactic. "Exploiting a remote service" is a technique, detailing the type of action used in pursuit of the tactic.

Procedure:The specific implementation or instance of a technique. "Use EternalBlue to exploit a remote SMB server" is a concrete procedure, an exact exploit tool or method used.

This hierarchy is fundamental to frameworks likeMITRE ATT&CK, which guides how analysts categorize and investigate adversary behaviors.

Splunk Answersis a community-driven Q&A platform where users can ask questions and share knowledge about Splunk. It is known for providing community-sourced answers to a wide range of questions, including SPL (Search Processing Language) queries, configuration issues, and general best practices. Users can contribute by answering questions based on their own experiences, making it a valuable resource for troubleshooting and learning.

B. Splunk Lantern:This is a resource for best practices, how-tos, and use case guides, but it’s not a community-sourced Q&A platform.

C. Splunk Guidebook:This is not a known resource in the context of community-sourced answers.

D. Splunk Documentation:While highly detailed and official, it is not community-sourced but rather maintained by Splunk's own teams.

Mean Time to Respond (MTTR)is a critical SOC metric measuring the average time from detection of a security incident to the point where it is resolved or dispositioned. According to theSplunk Enterprise Security and SOC Operations documentation, the typical start time for MTTR calculations iswhen a Notable Event is triggeredin Splunk ES. Notable Events represent the initial alert generated by correlation searches or detection mechanisms, marking the point where the SOC becomes aware of a potential incident requiring analyst review.

Starting MTTR at the time the malicious event occurs (option A) is impractical since detection is rarely instantaneous.

SOC Manager notification (option B) is too late in the workflow, as response metrics are analyst-focused.

Notifying end users (option D) is a post-response activity and does not define the start of response time.

This approach standardizes MTTR calculation across security operations and provides actionable insights into detection-to-response performance.
