Which of the following commands need to be configured on the four devices? (Multiple choice)

Question

Options

• ARegister-source Huawei
• BMultivregion-configuration
• CSoregion-configuration
• DGroup-address

• A
  81% (48)
• D
  19% (11)

Explanation

Options A, B, and C (Register-source Huawei, Multivregion-configuration, and Soregion-configuration) are all required commands when configuring the four devices in this multicast/regional network topology - each serves a distinct role in establishing the registration source identity, defining multi-region parameters, and specifying the source region settings respectively. These three commands work together as a complete configuration set that must be applied across all participating devices to ensure proper communication and coordination between regions.

Option D (Group-address) is incorrect not because group addressing is irrelevant to networking, but because it is a parameter or sub-command used within other configuration contexts rather than a standalone command required on all four devices in this scenario - it does not fulfill the same mandatory, device-wide configuration role as A, B, and C.

Memory tip: Think of it as "RSM" - Register, Source-region, Multi-region - the three active configuration commands the devices all need. Group-address is just an address value, not a configuration command in this context, so it's the odd one out.
