Question 260
A security operations team has two offices but both depend on one external alerting provider with no outage process. Which resilience or recovery decision most directly meets this business requirement?
Explanation
Correct Answer
Assess the external alerting supplier’s continuity commitments, shared infrastructure, dependency concentration and tested outage procedures. Arrange an independent fallback alerting path or secondary provider so both offices do not lose detection visibility during one third-party failure. Two physical security-operations locations do not provide resilience when their critical information feed has one unmitigated provider dependency. Verify escalation contacts and test the alternate notification workflow rather than relying solely on contract assurances.
Incorrect Answers
Versioned backup retention preserves earlier recovery points and prevents replicated mistakes from replacing all clean copies. The operations team instead depends on a live external alerting provider, and no backup version will generate real-time alerts when that service is unavailable. Recovery-point design addresses stored data, not the outsourced detection dependency.
Resilient DNS and identity services are important when authentication and name resolution must survive an outage. The question does not identify either as the shared weak point; both SOC offices rely on the same alerting provider. Adding identity redundancy would not necessarily preserve incoming third-party alerts.
An out-of-band communications plan provides alternate channels for responder coordination when normal enterprise messaging fails. It is useful during an alerting outage but does not independently detect events or deliver substitute alert feeds from another platform. Supplier continuity and a tested alternative detection path address the actual dependency.
