Hi,
The correct answer is:
CAR (Committed Access Rate) -> policies traffic based on its bandwidth allocation
PBR (Policy Based Routing) -> uses route maps to match traffic criteria
NBAR (Network Based Application Recognition) -> identification tool ideal for handling webapplications
best effort -> service level that provides basic connectivity without differentiation
hard QoS -> service level that provides reserved network resources
soft Qos -> service level that provides preferred handling
BR
