質問 # 34
Which of the following parameters is not mandatory for GRE configuration?
正解：C
解説：
Enabling the GRE checksum is optional. A functional point-to-point GRE tunnel requires a tunnel interface, GRE as the tunnel protocol, and reachable source and destination tunnel endpoints. The source identifies the local interface or IP address used to construct the delivery header, while the destination identifies the remote GRE endpoint. Without these endpoint parameters, the device cannot correctly encapsulate and deliver packets to the peer.
The checksum field is controlled by the Checksum Present bit in the GRE header. When checksum processing is enabled, the sender includes a checksum covering the GRE header and payload, and the receiver verifies it.
This can provide additional corruption detection, but it increases processing and is not required for basic GRE operation. RFC 2784 explicitly labels the checksum field as optional and states that it is present only when the Checksum Present bit is set.
Huawei SD-WAN uses GRE or GRE over IPsec to establish data channels between edge devices. The essential tunnel and transport-network information is distributed through the control system, while optional GRE functions such as checksum validation may be enabled according to operational requirements.

Which of the following WLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer network?
正解：C
解説：
A network serving 15,000 wireless terminals is a large-scale WLAN and should use a standalone WAC solution. A dedicated WAC provides independent controller resources, scalable AP and user management, centralized WLAN policy control, and the ability to deploy controller redundancy without tying wireless- control capacity directly to a specific core-switch service card.
Huawei recommends a standalone WAC when the wireless network scale is large or when the wireless network is deployed independently over an existing wired campus. The WAC is typically connected to the aggregation or core layer in off-path mode, and VRRP hot standby can be used to improve reliability.
Native WAC solutions are valuable for unified wired and wireless management, authentication, forwarding, and policy enforcement. However, for a very large number of wireless terminals, the controller platform must be selected according to user, AP, traffic, and forwarding-capacity specifications. A standalone WAC allows the wireless control plane to be sized and expanded independently.
Option C provides the dedicated WAC together with the required core and aggregation or access infrastructure. Therefore, it is the recommended architecture for 15,000 wireless terminals.
質問 # 36
In hierarchical networking, which of the following devices is used for communication between different areas?
正解：A
解説：
A border device, or more precisely a device at a border site, provides communication between different areas in a hierarchical SD-WAN topology. The hierarchical model divides a large WAN into multiple areas. Each area can independently use a hub-spoke or full-mesh topology, while selected border sites connect the local area to a centralized backbone area.
When a non-border site receives a route originating in another area, the route's next-hop site ID is changed to the border site in its own area. The local border device then forwards traffic toward the border site in the destination area or toward an interconnected hub site. Ordinary edge devices provide connectivity for their own sites but do not automatically perform cross-area transit.
Huawei describes border sites as members of both the level-2 area network and the level-1 backbone network.
These sites collectively implement interconnection between areas. Huawei further explains that inter-area routes point to border sites and recommends two border sites operating in active/standby mode for reliability.
Therefore, the correct answer is B.
質問 # 37
Which of the following deployment modes are supported by AR routers?
正解：A、C、D
解説：
AR routers support registration query center-based deployment, email-based deployment, and DHCP Option
148-based deployment. In registration query center deployment, the router obtains basic network connectivity, resolves or contacts Huawei's registration service, retrieves the address and port of iMaster NCE, and then initiates registration. Huawei identifies AR routers, firewalls, switches, and APs as applicable devices for this method.
Email-based deployment is a major SD-WAN ZTP method for AR routers operating as CPEs. An administrator creates the site and ZTP configuration on iMaster NCE and sends a deployment URL to the onsite engineer. After the URL is opened and the parameters are written to the router, the device connects to the WAN and automatically registers with the controller.
DHCP Option 148 can provide the controller's southbound IP address and port number to an IPv4 AR router, enabling automatic registration. Barcode scanning through the CloudCampus APP is specifically presented as an AP onboarding method, not an AR-router deployment method. Therefore, A, C, and D are correct.
質問 # 38
On a large campus network, inter-WAC roaming should be avoided as much as possible to ensure the roaming experience.
正解：A
解説：
The statement is true as a WLAN design recommendation. Inter-WAC roaming is supported, but it introduces more control-plane interaction and forwarding complexity than intra-WAC roaming. The Home WAC and Foreign WAC must belong to the same mobility group, synchronize station and AP information, and establish an inter-WAC CAPWAP tunnel for control information and, in some scenarios, service forwarding.
Additional synchronization, tunnel processing, route handling, and failure dependencies can increase roaming delay and complicate troubleshooting. This is especially relevant for delay-sensitive applications such as voice, video, automated guided vehicles, and real-time production systems. A better design places APs between which users frequently move under the same WAC wherever controller capacity and physical topology permit.
Avoiding inter-WAC roaming does not mean disabling the function entirely. Large campuses may require multiple WACs for scale, redundancy, or geographic distribution. Mobility groups should still be configured for unavoidable cross-controller movement. However, buildings, floors, and continuous roaming areas should be assigned carefully so that normal roaming remains intra-WAC. Therefore, the recommendation in the statement is correct, and the answer is True.
