A.DiffServ requires RSVP to set up a path through the network to accommodate the requested QoS.
B.Network traffic is identified by class， and the level of service is chosen for each class.
C.The DiffServ model relies on a fairly simple mechanism to provide QoS over a wide range of equipment.
D.RSVP enables the DiffServ model to provide end-to-end QoS.
E.The DiffServ model is more scalable than the IntServ model.
F.The flow-based approach of the DiffServ model is ideal for large scalable implementations such as the public Internet.

A.The customer uses SNMP statistics to create the policy.
B.QoS policy templates are generated and installed on the interface.
C.RTP is used to generate the policy.
D.LLQ，cRTP，and LFI are used to automatically discover the policy.
E.The auto-generated policy is manually optimized before implementation.
F.Auto-discovery is used to determine what traffic is on the interface.
A.WPA is based on the outdated IEEE 802.11i standard.
B.WPA uses RSN，which uses the same base encryption algorithm as RC4.
C.WPA requires a hardware upgrade that may not be supported by all vendors.
D.WPA uses TKIP，which uses the same base encryption algorithm as WEP.
E.WPA is susceptible to a DoS attack when it receives two packets in quick succession with bad MICs，forcing the AP to shut down the entire Basic Service Set （BSS） for one minute.
F.WPA is susceptible to a security weakness when preshared keys are used.
