Exam 300-410 topic 1 question 123 discussion

B is correct

IPsec (Internet Protocol Security) provides traffic segmentation and encryption within a DMVPN (Dynamic Multipoint Virtual Private Network) network. DMVPN is designed to provide secure, scalable, and dynamic communication between multiple sites over a shared, untrusted network (typically the Internet). IPsec is used in DMVPN to secure the communication between the remote sites (i.e., it encrypts and authenticates the traffic) to ensure that the data is protected and isolated from other traffic on the same underlying infrastructure.

Cisco IOS Release 12.4(11)T provides an enhancement that allows you to segment VPN traffic within a DMVPN tunnel. VRF instances are labeled, using MPLS, to indicate their source and destination.

I believe B is correct. IPsec (Internet Protocol Security) provides traffic segmentation within a DMVPN (Dynamic Multipoint Virtual Private Network) network by encrypting the data traffic between the DMVPN nodes. This ensures that the traffic is secure and segmented from other traffic, maintaining confidentiality and integrity across the network.

C is correct

option correct is C: Prerequisites for Dynamic Multipoint VPN (DMVPN) To enable 2547oDMPVN--Traffic Segmentation Within DMVPN you must configure multiprotocol label switching (MPLS) by using the mpls ip command. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_dmvpn/configuration/15-mt/sec-conn-dmvpn-15-mt-book/sec-conn-dmvpn-dmvpn.html
