Question 1060
A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption. Before changing security policy, what evidence should the engineer examine FIRST?
Explanation
Correct Answer
Inspect event schemas, correlation rules, playbook triggers, action scopes, approvals, and error-handling logs. This checks the relevant condition before an engineer modifies production access or detection behavior. A SIEM detection is analytic evidence, not automatically a permission to execute a destructive SOAR response. The controlled response would be: Use SIEM to search and correlate security telemetry and SOAR playbooks to coordinate authorized investigative or response actions. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
Incorrect Answers
Inspect observable sightings, integration health, incident timeline, detection confidence, and action permissions. This evidence addresses Cisco XDR cross-source incident correlation; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect event schemas, correlation rules, playbook triggers, action scopes, approvals, and error-handling logs. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
Inspect security agent health, supported application versions, posture evidence, policy exceptions, and dynamic authorization. This evidence addresses Endpoint application compliance and risk-based access; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect event schemas, correlation rules, playbook triggers, action scopes, approvals, and error-handling logs. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
Inspect current session identity, NAD CoA support and shared secret, ISE authorization change, and RADIUS live logs. This evidence addresses CoA session reauthorization by Cisco ISE; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect event schemas, correlation rules, playbook triggers, action scopes, approvals, and error-handling logs. Situation: A new automation quarantines every host matching one low-confidence DNS indicator and causes production disruption.
