Exam 4A0-220 Topic 1 Question 7 Discussion

Actual exam question for Nokia's 4A0-220 exam
Question #: 7
Topic #: 1
What is Tunnel Property Heritage?

Suggested Answer: D Vote an answer

Explanation
Tunnel Property Heritage is a feature of GMRE that allows the propagation of certain properties from higher order (HO) LSPs to lower order (LO) LSPs in a multi-layer network. These properties include cost, SRLG, and color. Cost is a metric that reflects the preference of using a certain link or path for routing. SRLG is a set of links that share a common risk of failure. Color is an attribute that can be used to group or filter LSPs based on service classes or customer profiles. By propagating these properties from HO to LO LSPs, GMRE can ensure that the end-to-end LSPs are consistent and optimal across different layers34. References:
