Cisco 350-201 Practice Test 92
Question 910
For an original CBRCOR educational scenario, consider: A small analysis script groups source addresses but treats each JSON event as a string and cannot access the nested src_ip field. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Check: Run the script against a fixture with successes, failures, missing fields and nested JSON values and compare expected counts.
- Change: Trace the script's parsing, conditional logic and collection operations, using typed decoded event fields for reliable classification.
- Change: Respect published quota and Retry-After behavior, use bounded backoff and distinguish lookup failure from indicator verdict.
- Use arbitrary substring searches as proof of event types without inspecting parsed fields or control flow.
- Check: Trace one rule change from commit to test results, approvals, artifact identity and observed production monitoring.
Explanation
Correct Answer
A:Python data structures and Boolean conditions determine which events contribute to an analytic; ambiguous text matching changes results. Acceptance: Counts match source semantics and missing or malformed records receive explicit handling rather than silent misclassification.
B:Python data structures and Boolean conditions determine which events contribute to an analytic; ambiguous text matching changes results. Evidence: Run the script against a fixture with successes, failures, missing fields and nested JSON values and compare expected counts.
Incorrect Answers
C:Change: Respect published quota and Retry-After behavior, use bounded backoff and distinguish lookup failure from indicator verdict. Python data structures and Boolean conditions determine which events contribute to an analytic; ambiguous text matching changes results.
D:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it. Python data structures and Boolean conditions determine which events contribute to an analytic; ambiguous text matching changes results.
E:Check: Trace one rule change from commit to test results, approvals, artifact identity and observed production monitoring. Python data structures and Boolean conditions determine which events contribute to an analytic; ambiguous text matching changes results.
Question 911
A SOC analyst is examining this cybersecurity operations situation: A threat enrichment loop stops processing after the first failed HTTP request because an exception escapes outside the per-indicator boundary. A proposed shortcut is: Suppress every error and reuse the previous indicator's verdict whenever a request times out. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Validate required environment values, handle missing variables explicitly and prevent secret values from entering command output or shell history.
- Suppress every error and reuse the previous indicator's verdict whenever a request times out.
- Enforce authenticated TLS, follow the documented authentication mechanism and scope credentials to the minimum operation.
- Inspect loops, variable scope and exception handling to ensure each indicator yields a distinct success or failure result.

Question 912
A Cisco cybersecurity incident response review finds: A threat enrichment loop stops processing after the first failed HTTP request because an exception escapes outside the per-indicator boundary.

Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- Environment variables can configure execution but are not automatically confidential or guaranteed to be present.
- Network timeouts may hide a committed server action, while oversized requests can be rejected or partially processed.

- Python control flow and exception boundaries determine whether an isolated lookup error corrupts a batch or leaves misleading state.
