4. Regarding the description of the MAC address spoofing attack, which of the following is wrong?

MAC address spoofing attack mainly uses the MAC address learning mechanism of the switch.

The attacker can implement MAC address spoofing attacks by sending a forged source Mac address data frame to the switch.

MAC address spoofing attacks will cause the switch to learn the wrong mapping relationship between MAC address and IP address.

MAC address spoofing attacks will cause the switch to send data to the correct destination instead of the attacker.

Question 4 of 25

5. Man-in-the-middle attacks or IP/MAC spoofing attacks can cause information leakage and other hazards, and they are more common in intranets.
In order to prevent man-in-the-middle attacks or IP/MAC spoofing attacks, the configuration methods that can be taken are:

Configure Trusted/Untrusted interface.

Limit the maximum number of MAC addresses that can be learned on the switch interface.

Enable DHCP snooping to check the function of CHADDR field in the DHCP REQUEST message.

Configure the linkage between DHCP snooping and DAI or IPSG on the switch.

Question 5 of 25

6. Regarding the description of the LDP Session establishment process, which of the following is correct? (Multiple Choice)

Two LSRs send HELLO messages to each other. The HELLO message carries the transmission address, and the party with the larger transmission address acts as the active party to initiate the establishment of a TCP connection.

If the Hello Message does not carry the Transport Address, the destination IP address of the Hello Message is used to establish a TCP connection, and the party with the larger IP address is the active party to initiate the establishment of the TCP connection.

The proactive party will send an Advertisement Message to negotiate the relevant parameters for establishing an LDP session, including the LDP protocol version and label distribution method. KeePalive maintains the timer value, maximum PDU length, and label space.

If the passive party can accept the relevant parameters, it will send Initialization I, message, and at the same time send a keepalive message to the active party.

Regarding the statement about ASPF and Server map table, which of the following is wrong?

ASPF monitors the messages in the communication process.

ASPF dynamically creates and deletes filtering rules.

ASPF uses Ser; ermak table to dynamically allow multi-channel protocol data to pass.

During the lease period, if the client receives a DHCP NAK message, the client will immediately stop using this IP address, return to the initialization state, and apply for a new IP address again.
