Huawei Cloud's self-developed database GaussDB (for Redis) provides multiple connection methods. Which of the following connection methods for GaussDB (for Redis) is wrong?

Question

Options

• AThird-party client connection
• BPublic network connection
• CIntranet connection
• DProgram code connection

• A
  77% (20)
• B
  4% (1)
• C
  15% (4)
• D
  4% (1)

Explanation

Option A is correct because GaussDB (for Redis) does not support connection via arbitrary third-party clients; it relies on Huawei-specific or protocol-compatible tooling for connectivity, making "third-party client connection" an invalid method for this database service. Options B, C, and D are all legitimate and documented connection methods: public network connection allows access from outside the cloud environment via an Elastic IP, intranet connection enables secure access within the same Virtual Private Cloud, and program code connection allows applications to connect directly through supported SDKs or drivers embedded in code. Each of B, C, and D represents a standard Huawei Cloud access pattern, which is why they are distractors rather than the answer.

Memory tip: Think of the three valid methods as covering three scopes -- external (public network), internal (intranet), and application-level (program code). If a method does not fit one of these three official scopes, it is likely the odd one out, which points you to third-party client connection as the unsupported option.
