Question 460
A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption. Which observed result BEST confirms that the security requirement is met?
Explanation
Correct Answer
Correlated suspicious activity creates a reviewable incident and only authorized containment actions execute under tested automation. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. A SIEM detection is analytic evidence, not automatically a permission to execute a destructive SOAR response. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
Incorrect Answers
Guests obtain only appropriate internet access while enrolled employees reach approved internal applications under auditable policy. This outcome tests Cisco ISE guest and BYOD identity policies and is not sufficient proof of the stated requirement. Here the relevant validation is: Correlated suspicious activity creates a reviewable incident and only authorized containment actions execute under tested automation. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
A linked multi-source incident supports proportional containment with evidence from affected devices and services. This outcome tests Cisco XDR cross-source incident correlation and is not sufficient proof of the stated requirement. Here the relevant validation is: Correlated suspicious activity creates a reviewable incident and only authorized containment actions execute under tested automation. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization. This outcome tests Cisco Duo multifactor and device trust policy and is not sufficient proof of the stated requirement. Here the relevant validation is: Correlated suspicious activity creates a reviewable incident and only authorized containment actions execute under tested automation. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
