Question 270
At Briarwood Property Group, a team reports that it corrected the following problem affecting tenant applications and facility services: Traffic inspection fails on a cluster because asymmetric routing sends response packets through a different stateful node. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
Bidirectional flows remain established across failover without bypassing enforcement. This is the decisive evidence for the original problem: Traffic inspection fails on a cluster because asymmetric routing sends response packets through a different stateful node. It verifies that the intended corrective control—Correct routing or session-state synchronization to maintain symmetric flow inspection—works in the relevant environment; a completed change ticket alone would not prove the outcome at Briarwood Property Group.
Incorrect Answers
Unauthorized lateral traffic is denied without requiring an Internet-edge crossing. This would be relevant evidence for a different failure: A virtualized workload environment moves east-west traffic beyond a physical perimeter firewall's view, usually addressed by Place segmentation and inspection controls at a virtual or workload network boundary. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: Bidirectional flows remain established across failover without bypassing enforcement.
Approved application traffic passes and unrelated tunneled applications are denied. This would be relevant evidence for a different failure: A firewall rule allows every application on TCP 443 although only a sanctioned service is needed, usually addressed by Apply supported application-aware policy matching rather than relying solely on destination ports. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: Bidirectional flows remain established across failover without bypassing enforcement.
Peak-load testing meets latency requirements while representative threats are detected. This would be relevant evidence for a different failure: A security manager enables intrusion inspection on all flows without measuring performance capacity, usually addressed by Size and scope inspection based on throughput, encrypted visibility, and policy criticality. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: Bidirectional flows remain established across failover without bypassing enforcement.
