Explanation

Context: This question tests understanding of a Huawei U1960 prefix configuration where users dial 9 to place an outgoing local call.

Why B and C are correct: The key is reading each attribute precisely. With Called number change: None, the dialed number (7000) is sent to the peer office unchanged - the system does not automatically expand it to 05717000. With Calling number change: 1 and Display long calling number: Yes, the caller's number is converted to long format and presented to the remote party. B and C correctly reflect these behaviors - the called number stays as 7000, while the calling party's number is displayed in long format.

Why the distractors are wrong: Option A likely claims the called number is converted to 05717000, which contradicts "Called number change: None" - that field controls the destination number, not the source. Option D likely describes a "normal case" scenario that ignores one of the configured parameters, leading to an incorrect conclusion about how the call is processed.

Memory tip: Use the acronym CD vs. CG - Called number change affects the Destination (where you're calling), while Calling number change affects the Giver (who's calling). "None" on the Called side means the destination number travels untouched; the change only applies to your own outgoing caller ID.
