What are the differences between traffic policing and traffic shaping?

• A.For traffic shaping, it can be over-CIR Traffic adjustment for the usage of the buffer
• B.For traffic shaping, the router caches excess packets until bandwidth is available again
• C.For traffic policing, the usage of the buffer can be adjusted for traffic exceeding the CIR
• D.Traffic shaping is applied in the inlet direction and traffic supervision is applied in the outlet direction
• E.The token bucket algorithm is used for traffic supervision, and the SPD algorithm is used for traffic shaping

The following is an error in the OSPF routing calculation (single choice).

• A.OSPF router uses the FULL SPF algorithm to calculate all nodes in the network when initially calculating routes
• B.Compared to the PRC algorithm, the ISPF algorithm only calculates the changed leaf nodes when the route changes PRC algorithm to recalculate routes
• C.When the first and second class LSAs on the network change, OSPF uses the ISPF algorithm to recalculate the routes The

Is the following description of the BSR/RP mechanism correct?

• A.BSR advertises BSR and C-RP information to all routers in the PIM-SM domain by flooding Bootstrap packets
• B.A C-BSR can also collect C-RP information by receiving C-RP packets
• C.PIM-SM domain can have more than one C-BSR, but only one BSR can be elected by the C-BSR that receives the C-RP Packets are collected C-one RP information

A workstation is connected to an Ethernet switch in the work through a super-class 5 wire, the workstation can access the entire network (that is, full connection) through the switch, but the access rate is much lower than expected, when viewing the switch interface statistics, you can detect that there are many ultra-small frames, with software to read the statistics of the workstation network card, found that there are Many FCS and frame alignment errors, what causes the machine to cause these errors?

• A.Interface mismatched to an 8021Qtrunk interface
• B.The network interface card on the workstation is damaged
• C.The operating mode between the workstation and the switch does not match
• D.The line between the workstation and the switch has been completely damaged
• E.The rate mismatch between the workstation and the switch
