Question 420
A new segmentation policy is deployed without testing critical application dependencies. Which management response BEST addresses the stated risk or governance priority?
Explanation
Correct Answer
Poorly tested segmentation can interrupt essential services. This directly meets the requirement to safely implement network zone restrictions.
Incorrect Answers
Least-privilege network rules reduce unnecessary attack paths. That action would restrict overbroad management network access; it does not address the case's priority to safely implement network zone restrictions.
Restricted communication paths reduce lateral movement from lower-trust assets. It is primarily relevant when the need is to separate guest and financial network trust, rather than to safely implement network zone restrictions.
Third-party connectivity creates attack paths that need explicit authorization. This would help govern partner network interconnection; the scenario instead requires a decision to safely implement network zone restrictions.
