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.

A /27 subnet mask is 255.255.255.224, which means each subnet contains 32 IP addresses. The subnet increments in blocks of 32 in the last octet: 0, 32, 64, 96, 128, 160, 192, 224. The address
192.168.1.200/27 belongs to the subnet 192.168.1.192/27.
For this subnet, the network address is 192.168.1.192, the broadcast address is 192.168.1.223, and the valid host range is from 192.168.1.193 to 192.168.1.222. Therefore, 192.168.1.221/27,
192.168.1.193/27, and 192.168.1.222/27 are all valid host addresses in the same subnet and are reachable at Layer 2 without routing. That makes A, C, and D correct.

UDP (User Datagram Protocol) is a connectionless protocol that does not provide reliability, packet sequencing, or traffic control. These features are usually managed by TCP, which is used for applications requiring reliable data transmission. UDP's design makes it suitable for real-time applications, such as video streaming or VoIP, where speed and low latency are prioritized over reliability.

An Ethernet switch learns MAC address entries dynamically by examining the source MAC address of incoming frames. When SW1 first receives frames from PC1 on GE1/0/1, it creates a MAC address table entry mapping PC1's MAC address to that port. If PC1 later sends frames that arrive on GE1/0/2, SW1 updates the learned entry to reflect the new incoming interface.
Therefore, option B is correct: SW1 saves the mapping between PC1's MAC address and GE1/0/2 and removes or overwrites the old mapping associated with GE1/0/1.

This statement is true. On a Huawei WAC, the number of APs that can go online is controlled by the available license resources. If a Fit AP fails to come online and the command display ap online-fail-record shows Insufficient license resources, it means the controller does not currently have enough licensed capacity to allow additional APs to register successfully.
In this case, the administrator must expand the license capacity or adjust existing license allocation so that the AP can be admitted. This is a common WLAN deployment issue, especially when new APs are added without first verifying the current AP license limit on the WAC. HCIA- Datacom troubleshooting methodology emphasizes interpreting controller diagnostics and fault records accurately. An AP can fail to go online for many reasons, including CAPWAP reachability problems, version mismatch, authentication issues, or licensing limitations. When the failure reason explicitly indicates insufficient license resources, the troubleshooting direction is clear: the controller's AP license capacity must be checked and, if necessary, increased. This question tests the ability to map a specific WAC alarm record to the correct operational response.
