Question 482
On Huawei switches, which of the following planes provides network information and forwarding entries that are mandatory for data plane forwarding?
Correct Answer: B
Comprehensive and Detailed in-depth Step-by-Step Explanation:To understand this question, let's first review the functional planes in network devices, particularly Huawei switches: * Control Plane: * The control plane is responsible for generating and maintaining routing tables and forwarding entries. * It uses protocols like OSPF, BGP, and RIP to exchange routing information with other network devices. Once the routing information is processed, it installs forwarding entries into the forwarding plane for actual packet forwarding. * On Huawei switches, the control plane is mandatory for building and updating the forwarding table. Without it, the data plane cannot forward traffic correctly. * Forwarding Plane (or Data Plane): * This plane handles the actual forwarding of packets based on the forwarding table created by the control plane. * The forwarding plane operates at high speed to ensure that traffic flows efficiently. * Monitoring Plane: * This plane is responsible for network management and monitoring. It gathers statistics and provides tools for troubleshooting and visibility. In this case, the control plane provides the routing information and forwarding entries required for the data plane to perform packet forwarding. Therefore, the correct answer is B. Control plane.

Question 483
OSPF has five types of packets, which have the same header format. If the Auth Type field in the packet header is 1, which of the following authentication modes is used?
Correct Answer: C
OSPF Authentication Overview TheAuth Typefield in the OSPF packet header determines the authentication mode. If theAuth Typeis 1, plaintext authentication is used. Plaintext authentication involves transmitting the password in an easily readable format, which is less secure compared to MD5. HCIP-Datacom-Core Reference Authentication mechanisms, including plaintext authentication, are detailed in the OSPF security configuration chapter, confirming thatAuth Type = 1corresponds to plaintext.
Question 484
BFD control packets are encapsulated in UDP packets for transmission. What is the destination port number of multi-hop BFD control packets?
Correct Answer: A
BFD control packets are encapsulated in UDP packets, and the destination port number for multi-hop BFD control packets is 4784. This is a standardized port for multi-hop BFD operation .
Question 485
Which of the following attacks is not a network layer attack?
