52. Frage
In the High-Quality 10 Gbps Campus Network Solution, which of the following experiences is improved by iMaster NCE-Campus?
Antwort: B
Begründung:
iMaster NCE-Campus primarily improves the operations and maintenance experience in this solution. It provides centralized planning, deployment, configuration, policy orchestration, monitoring, topology management, device management, alarm handling, and maintenance through a unified graphical interface.
Instead of configuring each switch, AP, WAC, firewall, or router separately, administrators can define services and policies centrally and deliver them across the network. Huawei states that iMaster NCE-Campus provides integrated LAN and WAN management, integrated deployment, integrated policies, and integrated O
& M, thereby improving deployment and O & M efficiency. It also provides network monitoring, service alarms, file management, log management, device maintenance, user management, and virtual-network management from one platform.
Wireless, wired, and application experience analysis is more directly associated with iMaster NCE- CampusInsight, which uses telemetry, AI, protocol tracing, and predictive analysis to quantify user and application experience. iMaster NCE-Campus serves as the management and control platform that simplifies administrators' daily work. Therefore, the experience specifically improved by iMaster NCE-Campus is the O
& M experience, making option C correct.
53. Frage
Which of the following slicing modes are supported?
Antwort: A,B,C,D
Begründung:
All four listed classification dimensions are supported slicing approaches in the relevant campus and SD- WAN context. A slice can be created from traffic characteristics, including a 5-tuple or an identified application, so selected flows receive dedicated forwarding, bandwidth, security, or quality policies. Huawei supports customized application identification using URLs and IP 5-tuple information, as well as application- and 5-tuple-based traffic steering and QoS.
VPN- or VN-based slicing provides logical Layer 3 isolation. Huawei's SD-WAN design maps each VN to an independent VPN instance or VRF and permits different overlay topologies, routing configurations, and policies. User-group-based slicing associates network treatment with identity or security-group membership rather than a permanently assigned IP address, supporting free mobility and consistent policy when users move. Huawei's campus architecture applies different permissions to different user groups inside a VN.
VLAN- or port-based slicing classifies traffic by the local access attachment and is useful for fixed terminals or environments without identity authentication. Therefore, A, B, C, and D are all correct.
54. Frage
Which of the following can be prevented by using the unauthorized access prevention function of Huawei switches?
Antwort: B,C
Begründung:
Huawei switches' unauthorized access prevention function can prevent users from connecting unauthorized hubs and sharing network access through unauthorized Wi-Fi hotspots. An unauthorized hub allows multiple terminals to enter the network through a port intended for a single managed endpoint. This can bypass normal terminal-count limitations, admission controls, and access-policy enforcement.
Unauthorized Wi-Fi hotspot sharing occurs when a user connects an authenticated endpoint to the enterprise network and then enables hotspot or connection-sharing functionality. Other terminals can subsequently access the network through that endpoint without completing the required authentication process. Huawei switches can analyze terminal behavior, MAC-address relationships, packet characteristics, and access patterns to identify and restrict this behavior.
A USB flash drive is a local storage device and does not provide Ethernet network access, so option A is unrelated to switch-based unauthorized network access prevention. An unauthorized router is normally controlled through device identification, NAC, port security, or explicit access policies rather than the specific hub and hotspot-sharing prevention function described by this question.
Huawei intelligent terminal management combines terminal identification, authorization, traffic analysis, and bogus-terminal detection to achieve visualized access and prevent unauthorized connectivity.
55. Frage
Which of the following protocol data packets can be encapsulated in a VPN using GRE?
Antwort: A,B,C,D
Begründung:
GRE is a multiprotocol encapsulation mechanism and can carry all the listed packet types. It inserts a GRE header around the original payload and then places the resulting GRE packet inside a delivery-protocol packet. Because the GRE header contains a Protocol Type field identifying the encapsulated payload, GRE is not restricted to ordinary IPv4 unicast traffic.
IPv6 packets can be transported as GRE payloads when supported by the tunnel endpoints. IP unicast traffic is the most common use case. GRE can also carry IP multicast and broadcast packets, which is one of its major advantages over basic IPsec tunnel selectors that traditionally focus on IP unicast traffic. This enables routing protocols, multicast applications, discovery traffic, and other non-unicast services to operate across a logical point-to-point tunnel.
RFC 2784 defines GRE as a general mechanism for encapsulating an arbitrary network-layer protocol over another network-layer protocol. It also defines the Protocol Type field used to identify the carried payload.
Huawei uses GRE as an SD-WAN overlay data-channel option and can additionally secure it using IPsec when confidentiality and integrity are required.
56. Frage
Which of the following statements is false?
Antwort: B
Begründung:
Option C is false. Traditional QoS can classify traffic and provide differentiated treatment for service categories such as voice, video, and ordinary data. It normally performs classification, marking, policing, shaping, congestion avoidance, and queue scheduling on an interface. This provides service-level differentiation but does not deliver sufficiently refined simultaneous management across multiple users and multiple applications.
Huawei's material explicitly states that traditional QoS schedules traffic based on port bandwidth and can differentiate traffic according to service levels, but it is difficult to distinguish traffic by user. It also states that traditional QoS cannot manage and schedule traffic from multiple services and multiple users simultaneously.
HQoS addresses this limitation through hierarchical, multi-level queues. For example, a parent level can allocate bandwidth to departments, VPNs, sites, or users, while child queues prioritize applications such as voice, video, email, and best-effort traffic. Huawei describes HQoS as hierarchical scheduling that differentiates both services and users. Therefore, statements A, B, and D are correct, while statement C incorrectly attributes an HQoS capability to traditional QoS.
