Explanation

Cloud Dedicated Line Access (option D) is not listed as a supported access method for Huawei Cloud database instances because dedicated line connectivity operates at the network infrastructure level and is not a distinct database access mode - it serves as an underlying transport, not a recognized access category for database services.

Options A, B, and C are all valid access methods: intranet IP access allows connections from within the same VPC or private network using the instance's internal address; public network IP access enables connections over the internet by binding an Elastic IP to the instance; and VPN access allows on-premises or remote environments to reach the database through an encrypted VPN tunnel connected to the cloud network.

Memory tip: Think of the three supported methods as covering three network zones - private (intranet), public (internet), and bridged (VPN). Dedicated Line is a hardware-level connectivity product, not an access mode the database service itself exposes, so it does not belong in this list.
