Question

Options

• BConfigure the peer device EID.
• CConfigure the protocol port of the peer device,
• DConfigure the IP address of the peer device.

• A

• B
  21% (4)

Explanation

When configuring a peer device for a SIP trunk on the U1900 unified gateway, you need three key pieces of information to establish the connection: the domain name (A), the protocol port (C), and the IP address (D). These three together define where and how to reach the peer - the IP address routes traffic to the correct host, the domain name enables DNS-based routing and SIP header matching, and the port specifies which transport endpoint to use (typically 5060 for SIP).

Option B (EID - Equipment Identifier) is the distractor. An EID is used to identify H.323 endpoints or internal devices within some Huawei gateway configurations, not to configure external SIP trunk peers. Applying H.323 concepts to a SIP trunk context is the trap here.

Memory tip: Think of it as sending a letter - you need the address (IP), the name on the mailbox (domain name), and the correct door/slot to deliver to (port). If you only remember one rule: SIP peers need "where + who + which port," not an equipment ID.
