When configuring a bridging ONU, how do you set the VLAN of the ETH1 port if the ETH1 port is used for a PC to access the Internet?

Question

Options

• AConfigure VLAN 1 on ETH1.
• BUse the default configuration of the ETH1 port.
• CConfigure VLAN 4094 on ETH1.
• DConfigure a native VLAN.

• A
  5% (1)
• B
  5% (1)
• C
  14% (3)
• D
  76% (16)

Explanation

Bridging ONU Configuration: A bridging ONU acts as a transparent bridge between the PC and the OLT, forwarding traffic without modifying it. VLAN Configuration for ETH1: VLAN 1: The default VLAN, often reserved for management purposes. Using it for Internet access is not recommended. Default Configuration: Leaving the port unconfigured may result in improper VLAN tagging or untagged traffic, leading to connectivity issues. VLAN 4094: Typically reserved for special purposes (e.g., QinQ termination) and is not suitable for general Internet access. Native VLAN: Configuring a native VLAN ensures that untagged traffic from the PC is associated with the correct VLAN for Internet access. Configuring a native VLAN is the correct approach to ensure proper VLAN tagging and seamless Internet access for the PC connected to ETH1. Thus, the correct answer is D.
