This statement is false . In campus network VLAN planning, VLAN IDs do not have to be allocated strictly consecutively without any gaps. In fact, leaving some reserved VLAN IDs is often a practical and recommended design approach. VLAN planning should focus on clarity, scalability, maintainability, and service separation , rather than on forcing all VLAN IDs to be contiguous.

For example, an administrator may reserve certain VLAN ranges for user access, voice services, management, wireless services, guest access, future expansion, or specific departments. Such structured planning makes later network expansion easier and reduces the risk of service conflicts or disruptive renumbering. HCIA-Datacom emphasizes that good campus network planning should consider current requirements and future growth. Consecutive allocation may look tidy at first, but it can actually reduce flexibility and make later additions more difficult. Therefore, the idea that VLAN IDs must be assigned consecutively without redundancy to avoid omissions is not a correct design principle. Reasonable reservation and categorized allocation are often more beneficial in real enterprise campus networks.

STelnet is Huawei ' s secure terminal service based on SSH and uses a client/server model. The device being remotely managed operates as the STelnet server, and the administrator ' s terminal acts as the client. A user who must modify device configuration also requires an adequate command privilege level; a level intended only for monitoring is insufficient. The false statement is A because the SSH/STelnet listening port cannot be set to literally any port number. Huawei VRP permits the default SSH server port 22 and, on common platforms and releases, configurable high-numbered ports within the documented allowed range. Port 1026 is a valid example of a non-default server port, but the wording " any port " is technically incorrect because reserved or disallowed values cannot be selected. Changing the listening port can reduce exposure to routine scans, but it does not remove the requirement for SSH authentication and access controls. Therefore the source answer A is valid when the complete wording of the option is considered.

On Huawei switches, a physical Ethernet interface usually works as a Layer 2 switch port by default. A Layer 2 interface cannot be assigned an IP address directly. If an administrator wants to configure an IP address on such an interface, the interface must first be converted into a Layer 3 interface . The command used for this is undo portswitch , so option B is correct.

After this command is executed, the interface no longer behaves as a Layer 2 switching port and can then support Layer 3 features such as direct IP address configuration. Options A , C , and D are all Layer 2 port-type commands used to configure the interface as a trunk, access, or hybrid port. These commands do not solve the problem because they keep the interface operating at Layer 2. HCIA-Datacom emphasizes the difference between Layer 2 switching interfaces and Layer 3 routed interfaces on switches. Understanding when to use undo portswitch is important in campus network deployment, especially when configuring routed uplinks, management interfaces, or inter-device Layer 3 links on switches.
