Suppose there are four flows a.b.c.d of 50M respectively, the total port bandwidth is 100M, traffic congestion occurs, and congestion management is performed on them. Among them, traffic a belongs to PQ queue scheduling, traffic b.c.d belongs to WFQ queue scheduling, and the weight ratio is 1:2:2. Which descriptions are wrong about the scheduling results for the four types of traffic? (Multiple choice)

• A.Flow b passes through 10M, flow c and d pass through 20M respectively
• B.The flow b passes through 25M, and the flow c and d pass through 12.5M respectively
• C.Traffic a through 100M
• D.Traffic a through 50M

The QoS technique commonly used for congestion avoidance is?

• A.WRED
• B.Car
• C.LR
• D.GTS

BFD determines whether a fault occurs by periodically detecting packets, and is a fast fault detection mechanism that relies on routing protocols.

• A.FALSE
• B.TRUE

As shown in the figure, in a medium-sized network, in order to improve the reliability of RR, BGP generally deploys double R.

When deploying dual EE, the Cluster IDs of the two RRs are generally set to be the same. What is the reason for this?

• A.Prevent loops
• B.Prevent the client from receiving too many routes and causing insufficient memory
• C.Prevent RR from receiving too many routes and causing insufficient memory
• D.Prevent suboptimal

As shown in the figure, on the R1 router, network administrator A can control the path of the traffic leaving AS100 after modifying the Local Preference value of the routing entry sent to R2 through the routing policy.

• A.FALSE
• B.TRUE
