JN0-661 Question #9: Real Exam Question with Answer & Explanation

The correct answer is B. LSPs with lower numerical setup priorities are computed before LSPs with higher setup priority C. The selected path for a given LSP is passed to RSVP in the form of an ERO.. The CSPF algorithm first calculates the highest-priority LSP (the one with the lowest setup priority Do I need to enable CSPF to control where to send my traffic? The answer is no.

Question

Which two statements are true regarding the CSPF algorithm? (Choose two.)

Options

AThe selected path for a given LSP is passed to the TED in the form of an ERO.
BLSPs with lower numerical setup priorities are computed before LSPs with higher setup priority
CThe selected path for a given LSP is passed to RSVP in the form of an ERO.
DLSPs with higher numerical setup priorities are computed before LSPs with lower setup priority

Explanation

The CSPF algorithm first calculates the highest-priority LSP (the one with the lowest setup priority Do I need to enable CSPF to control where to send my traffic? The answer is no. You can manually configure an Explicit Route Objects (ERO) list, and let RSVP doing the job. In the presence of the ERO object, the RSVP Path messages will follow the path specified, thus the Resv messages carrying the labels in the opposite direction.
