Question 382

WRED is configured on the newly deployed router HW The following description of the WRED feature is correct as ?( Multiple select).

WRED can set different drop thresholds and packet loss rates for packets of different priority

When traffic exceeds the minimum threshold, WRED starts dropping all ingress traffic (tail drops).

Avoid global synchronization by selectively dropping multiple TCP streams Low-bandwidth traffic is easier to drop than high-bandwidth traffic

Question 383

Regarding the FTP protocol, which of the descriptions below is correct?

In FTP Passive mode, the client completes the initialization of the TCP session for control and data

In FTP Active mode, the server tells the client which port it expects to send data on by commanding "PORT"

FTP always uses a TCP session to transmit control information and data information

FTP always uses TCP port 20 to establish a data session, and ICP port 21 to establish control will always use E. FTP TCP port 21 to establish a data session, TCP port 20 to establish a control session

RI, R2 establishes an EBGP neighbor and turns on the BFD detection function, the following statement is correct

Detection time for BFD packets for AR2 800ms

R1 Detection time for BFD packets for 1280ms

R1 Detection time for BFD packets The detection time for BFD packets for 660ms

R2 is 600ms

Question 385

In the use of the LACP protocol, the following description is correct ?( Multiple select).

You can avoid the Eth-Trunk interface from frequently shaking interface eth-trunk 1l lacp preempt enable lacp preempt delay delay-time with the following command

Source IP address load sharing, interface eth-trunk1Load-balance src-dst-ip, can be configured in an enabled link aggregation group with the following command

The member interface can be removed from an enabled link aggregation group with the following command: interface GigabitEthemeto/0/1 Shutdown nterface Gigabithemet/O/1undo ethtrunklinterface GigabitEthemet0/0/1 undo shutdown

A chain cluster that can be initiated through an order Join the member interface :interface GigabitEthemeto/0/1 shutdown interface igabitEthemetO/0/1 tunkportGigabitEthermet0/0/1 interface GigabitEthermet0/0/1 Undo shutdown

Question 386

The following statement about is the ISIS protocol LSP message is correct

LSP fast diffusion feature, first diffuse less than the specified number of LSPs, to speed up the synchronization process of LSDB

By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency of changes in routing information

When the link status information increases, the message length of the LSP can be increased so that each LSP can carry more information.

Reducing the minimum time interval for sending LSPs per port can speed up the diffusion of LSPs.

Question 387

Router RL and Router R2 run BGP both routers are in the AS65234 The router R2 route is present in the BGP routing table of router RI, but not in the P of router R1 road

With BGP, both routers are in the AS65234 Route cry PD is done by the right big worker

By the table, so what causes the problem to occur? A, synchronization is turned off

The B. BGP neighbor relationship is Down

Router R1 does not enable BGPMulti-hop D Routing is not optimal
