NEW QUESTION # 19
What is the maximum number of access units supported by a central switch on a passive Ethernet network (PEN)?
Answer: D
Explanation:
A central switch in the relevant passive Ethernet network architecture supports a maximum of 48 access units.
The architecture replaces a conventional multi-layer access design with a centralized switch and distributed remote or access units. The access units function as extensions of the central switch's ports, simplifying device management, configuration, and topology maintenance.
Huawei's CloudEngine S5731-H fixed central-switch specification provides models with 24 or 48 hybrid optical-electrical downlink ports. The 48-port model can therefore directly manage up to 48 associated access or remote units under the design limits represented by this question. The same hybrid links can provide data transmission and remote PoE power, enabling access units to be installed closer to terminals without requiring conventional active aggregation equipment at every location.
The central switch automatically discovers the topology, while remote units behave as extended ports rather than independently managed switches. This reduces management nodes and simplifies a traditional three- layer network into a two-layer architecture. The larger values of 64, 72, and 96 exceed the supported maximum for the specified central-switch implementation. Therefore, option C is correct.
NEW QUESTION # 20
On a large campus network, inter-WAC roaming should be avoided as much as possible to ensure the roaming experience.
Answer: A
Explanation:
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.
NEW QUESTION # 21
Which of the following are common terminal identification methods?
Answer: A,B,C,D
Explanation:
All four options are recognized terminal identification methods. MAC OUI examines the first three bytes of a device's MAC address to determine its manufacturer, although it generally cannot identify the exact model or operating system. DHCP option identification analyzes fields such as DHCP options 12, 55, and 60, which can reveal the hostname, parameter-request list, vendor class, and other terminal characteristics. SNMP query is an active identification method that retrieves device details from relevant MIB objects and is particularly useful for printers, network devices, and other SNMP-capable equipment.
Nmap is also an active scanning method. It analyzes open ports, service responses, protocol behavior, and operating-system fingerprints to estimate a terminal's device type and OS. Huawei distinguishes information- reporting methods from proactive scanning methods: MAC OUI and DHCP options generally use information observed in traffic, whereas SNMP and Nmap actively query or scan the endpoint. iMaster NCE-Campus can correlate multiple fingerprints to improve identification accuracy and automatically apply terminal-specific access policies.
NEW QUESTION # 22
Which of the following deployment modes are supported by APs?
Answer: A,B,D
Explanation:
APs support barcode scanning through the CloudCampus APP, DHCP Option 148-based deployment, and deployment through Huawei's registration query center. With barcode scanning, the installer scans the AP's label using the CloudCampus APP. The application obtains information such as the electronic serial number and MAC address, associates the AP with the correct tenant and site, and allows the AP to register with iMaster NCE.
With DHCP Option 148, the DHCP server supplies the AP with its IP configuration and the IP address and port number of iMaster NCE. The AP changes to cloud-management mode and automatically initiates registration. Huawei lists AR routers, switches, and APs as supported devices for this mode.
The registration query center can also provide the controller address after the AP contacts Huawei's query service. It supports APs together with ARs, firewalls, and switches. Email-based deployment is primarily an SD-WAN CPE or AR-router ZTP method, not an AP deployment mode. Therefore, A, C, and D are correct.
NEW QUESTION # 23
Which of the following statements is false about GRE over IPsec?
Answer: D
Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.
