What happens when an edge router using IntServ QoS determines that the data pathway cannot support the level of QoS requested?
- Data is forwarded along the pathway using IntServ but not provided preferential treatment.
- Data is forwarded along the pathway using DiffServ.
- Data is forwarded along the pathway using a best-effort approach.
- Data is not forwarded along the pathway.
Explanation: When the IntServ QoS model is being used, if network devices along a data path can reserve the required bandwidth, the originating application can begin transmitting. If the requested resource reservation cannot be allocated along the path, the originating application does not send any data.
