OSPF does indeed divide the routed domain into areas, and Area 0 (0.0.0.0) is mandated as the backbone area.

However, the Area ID field is 32 bits, allowing values from 0-to-4 294 967 295 (notation 0.0.0.0–255.255.255.255).

Saying the allowed range is only 0-255 is therefore inaccurate, so the statement is false.

Why Incorrect Option is Wrong:

• “True” would require the Area-ID range to be 0-255, which contradicts the 32-bit definition in both Huawei documentation and the OSPF standard.

This is a True/False question. The statement is factually incorrect due to the specified range for the Area ID, making the correct answer False.
