Challenges of Static VXLAN Tunnel Configuration
Astatic VXLAN tunnelrequires manualVTEP-to-VTEP configuration, making it complex to maintain.
#A. Heavy configuration workload in a distributed gateway scenario
Static VXLAN requires manual configuration of VTEP mappings, making itdifficult to scale and adjustwhen adding new VTEPs.
#B. Remote MAC addresses are learned through data flooding
UnlikeBGP EVPN-based VXLAN, whichadvertises MAC/IP bindings through BGP,static VXLAN relies on flooding for MAC learning, causingexcessive traffic.
#D. N(N-1)/2 tunnels are required for full mesh connectivity
IfN devices need to communicate, each must be manually configured withN(N-1)/2 VXLAN tunnels, leading tohigh administrative overhead.
Incorrect Statement Explanation:
#C. Static VXLAN tunnels use protocols on the control plane, consuming device resources.
Wrong!Static VXLANdoes not use a control plane protocollike BGP EVPN.
Instead,it relies entirely on static mappings, reducing control plane usage.

In Huawei'sFree Mobility solution:
Authentication Point (AP): Identifies users and associates them with aSecurity Group Tag (SGT)upon access.
Policy Enforcement Point (PEP): Enforces policiesbetween different security groups, such as allowing or denying traffic.
Key points:
Ais correct - The PEP enforces inter-group access based on defined policies.
Bis incorrect - AP and PEPcan be on separate devices, offering deployment flexibility.
Cis incorrect - Thepolicy enforcementhappens at thePEP, not the AP. AP ' s job is to authenticate and tag traffic.
Dis correct - AP and PEP can be deployed ondifferent devices.
Correct answers: A, D

HuaweiSD-WAN establishes secure tunnels between SD-WAN edge devices (CPEs, AR routers, and controllers) using tunneling protocols.
#B. GRE over IPsec(Correct Answer)
GRE (Generic Routing Encapsulation) over IPsecisthe primary tunneling method used in Huawei SD-WAN.
GRE provides multi-protocol encapsulation, whileIPsec ensures encryption and security.
Used forsecure communication over public WAN links (e.g., the internet, LTE, MPLS, etc.).

Understanding iMaster NCE-Campus Terminal Identification
Huawei's iMaster NCE-Campus is an AI-driven network management platform for campus networks.

In IPsec, a symmetric encryption algorithm (e.g., AES) is used for encrypting data due to its speed. To securely exchange the symmetric key between peers, asymmetric encryption algorithms (like RSA) are used.
This method ensures:
High performance (due to fast symmetric encryption)
Secure key exchange (asymmetric protection)
Exact Extract - Huawei HCIE-Datacom Guide - IPsec Encryption:
"IPsec uses symmetric algorithms to encrypt data for performance and asymmetric algorithms to securely exchange symmetric keys during IKE negotiation." Reference:
