Which two features describe TI-LFA?

TI-LFA uses PQ or P and Q nodes on the post-convergence path to compute the backup path.

Post-convergence, TI-LFA considers the next-hop neighbor to calculate the backup repair path.

TI-LFA works with point of local repair when the PQ node supports only LDP capability.

Unlike RLFA, TI-LFA works without the PQ node and provides double segment failure protection.

TI-LFA leverages the post-convergence path that carries data traffic after a failure.
