Nokia Certified Network Associate – Data Center — Question 21

In the context of a network that includes a Path Computation Element (PCE), what is a PCC-initiated LSP?

Answer options

• A. An LSP that needs to be explicitly configured on the head-end router.
• B. An LSP for which the initial path is calculated by the head-end router.
• C. An LSP for which the path repairs and re-optimizations must be triggered by the head-end router.
• D. An LSP whose existence and state are reported to the PCE.

Correct answer: D

Explanation

The correct answer is D, as a PCC-initiated LSP is one whose existence and operational state are communicated to the PCE. Option A is incorrect because it implies manual configuration, while option B incorrectly suggests the head-end router calculates the initial path. Option C misrepresents the role of the head-end router, as it does not trigger repairs for a PCC-initiated LSP.
