QUESTION NO: 3
To allow access to a VXLAN network, you need to configure service access points on devices.
There are two access modes: Layer ? sub-interface and binding. (Enter the acronym in uppercase letters.)
To allow access to a VXLAN network, you need to configure service access points on devices.
There are two access modes: Layer ? sub-interface and binding. (Enter the acronym in uppercase letters.)
Correct Answer:
3
Explanation:
VXLAN (Virtual Extensible LAN) is a network overlay technology that extends Layer 2 networks over a Layer 3 underlay, commonly implemented in Huawei's CloudFabric data center solutions.
To enable access to a VXLAN network, service access points (e.g., interfaces or sub-interfaces) must be configured on devices such as switches or routers acting as VXLAN Tunnel Endpoints (VTEPs). The question mentions two access modes: "Layer ? sub-interface" and "binding," with the task to fill in the layer acronym in uppercase letters.
Context Analysis: The missing layer is indicated by a "?" and is part of a sub-interface configuration. In networking, sub-interfaces are typically associated with Layer 3 (e.g., for VLAN tagging or VXLAN integration), where they handle IP routing or mapping to overlay networks.
Access Modes:
Layer 3 Sub-Interface: This mode involves configuring a sub-interface on a Layer 3 device (e.g., a router or Layer 3 switch) to terminate VXLAN tunnels and perform routing. The sub-interface is associated with a VNI (VXLAN Network Identifier) and often uses a Layer 3 protocol (e.g., BGP EVPN) to connect to the VXLAN overlay.
Binding: This likely refers to binding a VNI to a Bridge Domain (BD) or interface, a common practice in Huawei's VXLAN configuration to map the overlay network to a physical or logical port.
This can occur at Layer 2 or Layer 3, but the sub-interface context suggests Layer 3 involvement.
The question's structure implies the layer number for the sub-interface mode, which is Layer 3 in VXLAN contexts for routing and gateway functions. Thus, the acronym (digit) to enter is 3.
