Why should team members understand an automated script?

SY0-701 By islever Editorial Last updated

Short answer

D To prevent a single point of failure

Question

A security analyst developed a script to automate a trivial and repeatable task. Which of the following best describes the benefits of ensuring other team members understand how the script works?
  1. To reduce implementation cost
  2. To identify complexity
  3. To remediate technical debt
  4. To prevent a single point of failure Correct Answer

Key Takeaways

Tests your ability to recognize how cross-training mitigates key-person risk, while the trap confuses personnel dependency with technical system failures.

Sharing knowledge of automated scripts eliminates key-person dependency and ensures uninterrupted business operations. The community unanimously agrees that cross-training directly mitigates personnel-related single points of failure.

Common mistake: Option C is frequently selected incorrectly because candidates conflate undocumented automation with technical debt, overlooking that the scenario specifically addresses operational continuity through shared expertise rather than code refactoring.

Expert Analysis

Why the Answer Is Correct

Sharing script knowledge directly addresses key-person dependency, which is a classic single point of failure in IT operations. When multiple team members can maintain, debug, or execute the automation, the organization avoids downtime if the original developer is unavailable. CompTIA emphasizes this practice as a core component of robust operational security and change management protocols.

Why the Other Options Are Wrong

Option A focuses on financial savings, but cross-training scripts does not inherently lower initial implementation costs. Option B suggests identifying complexity, yet the prompt explicitly states the task is trivial and repeatable. Option C references technical debt, which typically involves poor code quality or lack of documentation over time, not the immediate operational risk of sole ownership.

Community Comment Notes

The community strongly supports D, noting that relying on one individual creates unnecessary operational risk. Comment [2] correctly highlights that shared knowledge eliminates reliance on a single employee during script failures or absences. Comment [4] reinforces this by emphasizing continuity and reduced individual dependency. While Comment [3] argues the script itself remains a single point of failure, this misses the question’s focus on personnel training rather than architectural redundancy.

Exam Strategy

When answering questions about automation or documentation, always look for keywords like "understand," "share," or "cross-train," as they typically point to mitigating key-person dependency. Avoid selecting options focused on cost or code quality unless the scenario explicitly mentions budget constraints or legacy system issues.
