NEW QUESTION # 111
Which of the following are Layer 2 Ethernet interfaces on a switch?
- A. Trunk
- B. Core
- C. Access
- D. Hybrid
- E. Agg
Answer: A,C,D
Explanation:
In Huawei switches, Layer 2 Ethernet interfaces are used to forward data at the data link layer (Layer 2) of the OSI model. These interfaces are essential for VLAN segmentation and communication within a local area network (LAN). The three main types of Layer 2 Ethernet interfaces are:
* Hybrid:A hybrid interface can carry traffic from multiple VLANs and is highly flexible. It allows both tagged and untagged traffic, making it suitable for complex network designs.
* Trunk:A trunk interface is used to carry traffic from multiple VLANs between switches or other network devices. It typically tags VLAN traffic using IEEE 802.1Q encapsulation.
* Access:An access interface is associated with a single VLAN and is used to connect end devices like PCs or IP phones. It carries untagged traffic by default.
The options "Agg" (likely referring to aggregation) and "Core" are not Layer 2 interface types but rather refer to higher-level concepts like link aggregation or core network architecture.
