Explanation:
B, A, D, C
The HCIA-Datacom V2.0 Training Material explains that DHCP clients obtain IP addresses through four stages: Discovery, Offer, Request, and Acknowledgment.
In stage 1, the client broadcasts a DHCP DISCOVER message to locate available DHCP servers because it does not yet know the server ' s IP address.
In stage 2, a DHCP server responds with a DHCP OFFER containing an available IP address and other configuration parameters.
In stage 3, the client broadcasts a DHCP REQUEST to indicate the selected server and requested address.
Finally, in stage 4, the selected server sends a DHCP ACK confirming the allocation.
This four-stage process is commonly called DORA: Discover, Offer, Request, and Acknowledge.
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 PC2 successfully pings the IP address of PC1. 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 connects GE1/0/1 of SW1 to another switch. Then, the administrator pings the IP address of PC1 from PC2. In this case, SW1 discards the data frame received from PC2.

On the network shown in the figure, the interfaces connecting switches to terminals are access interfaces, and the interfaces connecting switches to each other are trunk interfaces. The administrator configures interface- based VLAN assignment. PC1 and PC3 belong to VLAN 2, and PC2 and PC4 belong to VLAN 3. Trunk interfaces allow packets from VLAN 2 and VLAN 3 to pass through and use the default PVID. The MAC address tables of switches are empty. When SW1 receives a unicast data frame sent from PC1 to PC3, through which of the following interfaces does SW1 not send the data frame?

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?
