IPsec VPN supports a variety ofsymmetric encryption algorithmsto protect data confidentiality during transmission. Commonly supported algorithms includeDES,3DES, andAES, all of which are used to encrypt the payload of IP packets in ESP.

AESis the most widely recommended algorithm due to its strong security and high performance.3DESandDESare legacy algorithms that are still supported for compatibility reasons, although they are considered less secure and are gradually being phased out in modern deployments.

DSA (Digital Signature Algorithm), however, isnot an encryption algorithm. It is an asymmetric algorithm used fordigital signatures and authentication, not for encrypting data. IPsec uses DSA only indirectly in certificate-based authentication scenarios, but it is never used as a data encryption algorithm in IPsec VPNs.

According to HCIP Datacom Campus Network documentation, IPsec VPN encryption relies exclusively on symmetric encryption algorithms such as DES, 3DES, and AES. Therefore,DSA is not supported as an IPsec encryption algorithm, makingoption Athe correct answer.

Explanation (Concise and Technical)

Position 1 → 100This corresponds toVNI 100, which is associated with BD10 and is used for communication between PC1 and PC3.

Position 2 → 3.3.3.3This is theremote VTEP IP addressof VTEP3, configured as a head-end peer for VNI 100 on VTEP1.

Position 3 → 200This representsVNI 200, which is bound to BD20 and enables VXLAN communication between PC2 and PC4.

Position 4 → 1.1.1.1This is theremote VTEP IP addressof VTEP1, configured as a head-end peer for VNI 200 on VTEP2.

This mapping follows standardstatic VXLAN tunnel configuration logicon Huawei devices, where each VNI is explicitly associated with remote VTEP peer addresses using head-end peer-list.

Dynamic VLAN authorization allows edge devices to dynamically assign users to specific VLANs based on authentication results. This mechanism is widely used to guide user traffic into the correct VN in a CloudCampus virtualized campus network.

Forwired users, bothMAC address authenticationand802.1X authenticationsupport dynamic VLAN assignment. Once authentication succeeds, the authentication server delivers authorization VLAN information to the edge node, and users are placed into the corresponding VLANs. Therefore, statementsCandDare correct.

Forwireless users,802.1X authenticationalso supports dynamic VLAN authorization, making statementBcorrect. However,Portal authentication for wireless users does not support dynamic VLAN assignmentin CloudCampus networks. Wireless Portal authentication typically controls access rights rather than VLAN placement.

According to HCIP Datacom Campus Network documentation, statement A is false, making it the correct answer.
