On the network shown in the figure, the administrator creates Eth-Trunk 1 in manual mode on SW1 and SW2, and adds GE1/0/1 and GE1/0/2 on both switches to the Eth-Trunk. After the administrator runs the display interface brief command on SW1, the administrator finds that GE1/0/1 is Up and GE1/0/2 is Down. Which of the following statements is true about this scenario?

R1 has the following configurations:

Which of the following statements is true?

RSTP uses the proposal/agreement mechanism to shorten the time that an upstream port waits before transitioning to the Forwarding state, but no temporary loop occurs. Why?

Which of the following statements are true about the Python code shown below? (Select all that apply) import paramiko import time ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('192.168.1.254', username='python', password='Huawei@123') channel = ssh.invoke_shell() channel.send('screen-length 0 temporary\n') time.sleep(1) output = channel.recv(65535).decode('utf-8') print(output) ssh.close()

Four links between two switches establish an Eth-Trunk in manual mode, and the bandwidth of each link is 1 Gbit/s. One of the links fails. Which of the following statements are true about this scenario? (Select all that apply)

Which of the following commands can be used to check OSPF routes in the global routing table?

Which of the following fields are included in an MPLS header?

On a switched network where STP is enabled on all devices, when a downstream device detects a topology change, it continuously sends configuration BPDUs to the upstream device until the root bridge is informed of the topology change.

The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds. The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1. Then, the administrator disconnects the Ethernet cable of PC1 from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?
