Show Answer
Correct Answer: AB

In an IS-IS (Intermediate System to Intermediate System) network, prefixes in Level 1 (intra-area) are typically redistributed to Level 2 (inter-area) by default, allowing inter-area routing. However, prefixes in Level 2 are not automatically redistributed to Level 1 unless explicitly configured through an export policy. Therefore, the statements that prefixes in Level 1 will be redistributed to Level 2, and prefixes in Level 2 will not be redistributed to Level 1, are both correct.

Correct Answer AB. By default, IS-IS protocol leaks routing information from a Level 1 area to a Level 2 area. However, to leak routing information from a Level 2 area to a Level 1 area, an export policy must be explicitly configured.
