Cisco 350-201 Practice Test 93
Question 920
For an original CBRCOR educational scenario, consider: An IOC script sets its result variable only inside a successful branch and later reports a stale value for a failed lookup. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Suppress every error and reuse the previous indicator's verdict whenever a request times out.
- Change: Inspect loops, variable scope and exception handling to ensure each indicator yields a distinct success or failure result.
- Change: Use a SOAR case workflow that coordinates enrichments, decisions, tickets and authorized response actions with visible state and handoffs.
- Check: Test TLS certificate validation and low-privilege access with intended reads and denied administrative operations.
- Check: Test two good indicators and one timed-out lookup with mocked responses, checking result mapping and exit status.
Explanation
Correct Answer
B:Python control flow and exception boundaries determine whether an isolated lookup error corrupts a batch or leaves misleading state. Acceptance: Failed enrichments are visible while unaffected indicators continue according to documented policy.
E:Python control flow and exception boundaries determine whether an isolated lookup error corrupts a batch or leaves misleading state. Required intervention: Inspect loops, variable scope and exception handling to ensure each indicator yields a distinct success or failure result.
Incorrect Answers
A:Python control flow and exception boundaries determine whether an isolated lookup error corrupts a batch or leaves misleading state. Use this instead: Inspect loops, variable scope and exception handling to ensure each indicator yields a distinct success or failure result.
C:This option addresses a different security operations topic (SOAR orchestration versus isolated automation) rather than the documented Python iteration and exception paths in enrichment decision.
D:Check: Test TLS certificate validation and low-privilege access with intended reads and denied administrative operations. Python control flow and exception boundaries determine whether an isolated lookup error corrupts a batch or leaves misleading state.
Question 921
A SOC analyst is examining this cybersecurity operations situation: A SOAR ingestion script accepts malformed IP strings and sends every entry to the firewall API as a blocking request. A proposed shortcut is: Automatically block every unparsed input and print authentication headers to speed troubleshooting. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Honor documented payload limits, timeouts, idempotency and asynchronous action confirmation in automation clients.
- Trace the script's parsing, conditional logic and collection operations, using typed decoded event fields for reliable classification.
- Add format validation, safe API request construction, secret redaction and controlled action conditions before using the script operationally.
- Automatically block every unparsed input and print authentication headers to speed troubleshooting.
Explanation
Correct Answer
C:This targeted action addresses the observed security or operational control gap without discarding necessary controls. Security automation must distinguish candidate input from approved action and avoid making logs a new credential exposure source.
Incorrect Answers
A:Honor documented payload limits, timeouts, idempotency and asynchronous action confirmation in automation clients. Security automation must distinguish candidate input from approved action and avoid making logs a new credential exposure source.

D:Security automation must distinguish candidate input from approved action and avoid making logs a new credential exposure source. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
Question 922
A Cisco cybersecurity incident response review finds: A SOAR ingestion script accepts malformed IP strings and sends every entry to the firewall API as a blocking request. The team proposes: Add format validation, safe API request construction, secret redaction and controlled action conditions before using the script operationally. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- Python control flow and exception boundaries determine whether an isolated lookup error corrupts a batch or leaves misleading state.
- HTTP responses carry a status, headers and optional body; successful no-content responses need not contain JSON.
- Security automation must distinguish candidate input from approved action and avoid making logs a new credential exposure source.
- Presentation markup is not automatically a stable structured interchange format and may conceal context needed by incident logic.
Explanation
Correct Answer
C:Relevant validation before approval: Exercise malformed indicators, valid samples and an induced error while inspecting outbound requests and sanitized logging. Demonstrable success requires: Only validated authorized indicators progress and no credentials appear in source files or logs.

Question 924
A candidate correction has been tested and the platform team requires a post-change acceptance check. Original problem: A SOAR ingestion script accepts malformed IP strings and sends every entry to the firewall API as a blocking request. The response owner needs positive and negative results and evidence that legitimate security and business workflows still function. Which acceptance result demonstrates correct security operations behavior without disrupting authorized workflows? Select ONE best answer.
- Unauthorized actions fail clearly and the selected remediation matches the observed error rather than blind retries.
- Only validated authorized indicators progress and no credentials appear in source files or logs.
- Failed enrichments are visible while unaffected indicators continue according to documented policy.
- Counts match source semantics and missing or malformed records receive explicit handling rather than silent misclassification.
Explanation
Correct Answer
B:Security automation must distinguish candidate input from approved action and avoid making logs a new credential exposure source. The result must be validated using the documented device, service or access context.
