1. 1An analytic detector learns a baseline of normal endpoint activity and flags significant departures from that baseline, including previously unseen behavior. Which detection approach does the alert reflect?

   1. A.Anomaly-based detectionCorrect answer: A
   2. B.Signature-based detection
   3. C.Stateful protocol analysis
   4. D.Indicator matching

   Explanation: NIST defines "Anomaly-based detection" as comparing normal activity with observed events to identify significant deviations. The detector uses a learned baseline rather than requiring a fixed known attack signature.

2. 2An endpoint process-creation log shows process 190 has parent 30, process 30 has parent 10, and process 10 has parent 1. Which ordered chain reconstructs the observed lineage from the earliest listed ancestor to process 190?

   1. A.1 → 10 → 30 → 190Correct answer: A
   2. B.190 → 30 → 10 → 1
   3. C.1 → 30 → 10 → 190
   4. D.10 → 1 → 30 → 190

   Explanation: The detection strategy focuses on "parent-child relationships" in process execution chains. The recorded parent identifiers give 1 → 10 → 30 → 190 when followed from ancestor to descendant.

3. 3A SOC team repeatedly enriches alerts, evaluates the results and performs response steps in the same order. Which automation mechanism organizes these steps into a reusable workflow?

   1. A.A scheduled job
   2. B.An automation rule
   3. C.A playbookCorrect answer: C
   4. D.A quick action

   Explanation: The documentation describes playbooks as "a series of tasks that run in a predefined flow" and explains that they standardize investigation and response workflows.

4. 4An analyst queries authentication events and wants to retain only records whose outcome equals failure. Which query operation should the analyst apply?

   1. A.Join
   2. B.FilterCorrect answer: B
   3. C.Sort
   4. D.Deduplicate

   Explanation: The reference says the filter stage "identifies which records should be included in the result set by evaluating boolean expressions." Testing the outcome against the desired value selects the matching records.

5. 5A laptop's host-protection policy selects an office profile only while directly attached to the office LAN; it uses a travel profile in other network environments. The laptop is first on the office LAN, then moves to a public network and accesses the office through a VPN. Which profiles should be active in the two environments, respectively?

   1. A.Office, travelCorrect answer: A
   2. B.Travel, office
   3. C.Office, office
   4. D.Travel, travel

   Explanation: NIST explains that "Some products permit multiple policies to be configured on a host for multiple environments". Under the stated configuration, the direct office LAN connection uses the office profile; a VPN over a public network uses the travel profile.

6. 6An intelligence feed sends a signed ciphertext containing a compressed indicator file. Its signature covers the ciphertext, which must be authenticated before decryption. Which processing order makes the indicators available for use?

   1. A.Validate, decrypt, decompress, then extractCorrect answer: A
   2. B.Decrypt, validate, decompress, then extract
   3. C.Validate, decompress, decrypt, then extract
   4. D.Validate, decrypt, extract, then decompress

   Explanation: NIST describes validation, decryption, decompression, and content extraction and states that "These activities are typically performed in the order described above, but the order may vary based on specific operational or security requirements." Here the signature covers ciphertext, so it is checked first; the compressed file must then be decrypted and unpacked before its indicators can be extracted.

7. 7A team assigns each incident a priority score where a higher score means greater urgency. Cases P, Q, R, and S have scores of 41, 73, 62, and 58, respectively. In what order should the analyst review them by descending priority?

   1. A.Q, R, S, PCorrect answer: A
   2. B.Q, S, R, P
   3. C.P, S, R, Q
   4. D.R, Q, S, P

   Explanation: The scoring guide says "A case score is a numeric value that indicates the urgency of a case." Under the stated higher-is-more-urgent policy, sorting 73, 62, 58, and 41 gives Q, R, S, P.

8. 8A response automation requests an endpoint action for 10 hosts. The action record shows 3 failed and 1 still pending; the remaining targets completed successfully. How many endpoints have confirmed success?

   1. A.6 endpointsCorrect answer: A
   2. B.7 endpoints
   3. C.9 endpoints
   4. D.10 endpoints

   Explanation: The action guide states that you can view "the number of endpoints on which the action was successful and the number of endpoints on which the action failed." Excluding the 3 failures and 1 pending endpoint from 10 leaves 6 confirmed successes.

9. 9Several response workflows need the same IP-enrichment sequence. What component can an engineer nest in each parent workflow to reuse that sequence?

   1. A.A conditional task
   2. B.A sub-playbookCorrect answer: B
   3. C.A standard task
   4. D.A manual task

   Explanation: The guide states, "Sub-playbooks are playbooks that are nested under other playbooks." It also describes them as reusable building blocks and explains that inputs and outputs can pass between parent and child.

10. 10While reviewing query results, an analyst needs the name and data type of each returned field. Which query resource provides that information?

    1. A.The query history
    2. B.The query scheduler
    3. C.The result schemaCorrect answer: C
    4. D.The query library

    Explanation: The query interface documentation says "Schema: Lists each result-set field, its data type, descriptive text, and dataset." The schema is therefore the relevant resource for inspecting result fields.
