Question 130
At Brightstone Legal, a team reports that it corrected the following problem affecting client matters and confidential documents: A large hub-and-spoke organization needs dynamically established encrypted spoke-to-spoke paths. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
Authorized spoke pairs establish protected paths without routing all payload traffic through the hub. This is the decisive evidence for the original problem: A large hub-and-spoke organization needs dynamically established encrypted spoke-to-spoke paths. It verifies that the intended corrective control—Use a supported DMVPN design with controlled NHRP and IPsec protection—works in the relevant environment; a completed change ticket alone would not prove the outcome at Brightstone Legal.
Incorrect Answers
Authorized group members decrypt permitted traffic and a nonmember cannot use group keys. This would be relevant evidence for a different failure: A network design requires encryption of multicast group traffic across a private WAN overlay, usually addressed by Evaluate GETVPN group-key encryption where the transport supports its required routing properties. It does not demonstrate that the current problem at Brightstone Legal was resolved. The specific required evidence is: Authorized spoke pairs establish protected paths without routing all payload traffic through the hub.
Configured peers match the intended profile and successfully route authorized encrypted traffic. This would be relevant evidence for a different failure: An organization needs a scalable framework integrating remote access, tunnel profiles, and IPsec policy reuse, usually addressed by Use appropriate FlexVPN virtual tunnel interfaces and IKEv2 profiles for the defined topology. It does not demonstrate that the current problem at Brightstone Legal was resolved. The specific required evidence is: Authorized spoke pairs establish protected paths without routing all payload traffic through the hub.
IKE negotiation succeeds with mutually accepted secure proposals. This would be relevant evidence for a different failure: A site-to-site tunnel fails because two peers propose incompatible IKE algorithms, usually addressed by Align policy proposals for IKE version, cipher, integrity or PRF, DH group, and authentication. It does not demonstrate that the current problem at Brightstone Legal was resolved. The specific required evidence is: Authorized spoke pairs establish protected paths without routing all payload traffic through the hub.
