Refer to the Exhibit.
As shown in the exhibit, you have an adaptive LSP that requires 85 Mbps. The LSP is configured
with a primary path and a secondary path in standby mode. All connections in the MPLS network
are Fast Ethernet. Which statement is correct?
A.
The primary and secondary paths are in an up state and operational.
B.
The primary and secondary paths are in a down state and not operational.
C.
The secondary path is in a down state and not operational.
D.
The primary path is in a down state and not operational.
I would say C) – we need 170Mbps available:

Should be A, Both LSP paths are up, But only 1 of them is chosen to be used.

adaptive means shared explicit reservation which means that resources are not double counted so A is the right one.
