Question 620
During a cross-team security policy review at Atlas Scientific, engineers say that they resolved this finding: Applications across clouds communicate over wide IP ranges with no consistent east-west access policy. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
An unauthorized cross-cloud service connection is denied while a specific approved path works. This is the decisive evidence for the original problem: Applications across clouds communicate over wide IP ranges with no consistent east-west access policy. It verifies that the intended corrective control—Apply supported multicloud segmentation controls such as Cisco Multicloud Defense for network paths—works in the relevant environment; a completed change ticket alone would not prove the outcome at Atlas Scientific.
Incorrect Answers
Only authorized management sources can establish sessions to the protected workloads. This would be relevant evidence for a different failure: A multicloud deployment allows unrestricted inbound management traffic to public workload interfaces, usually addressed by Apply least-privilege security policy at the cloud network and host exposure points. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: An unauthorized cross-cloud service connection is denied while a specific approved path works.
The dependency map distinguishes necessary traffic and a proposed quarantine preserves essential services. This would be relevant evidence for a different failure: A team cannot identify workload-level dependencies before isolating compromised cloud instances, usually addressed by Use workload visibility and policy mapping with a solution such as Cisco Secure Workload. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: An unauthorized cross-cloud service connection is denied while a specific approved path works.
Storage inspection and unauthorized-key tests show data remains confidential. This would be relevant evidence for a different failure: A cloud app stores sensitive information unencrypted even though provider infrastructure is physically secure, usually addressed by Apply application and data encryption with customer-controlled key access policies as required. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: An unauthorized cross-cloud service connection is denied while a specific approved path works.
