NEW QUESTION # 33
If multiple Internet links are available, these links cannot be prioritized and can only be load-balanced.
Answer: B
Explanation:
The statement is false because Huawei SD-WAN supports both priority-based link selection and load balancing. Multiple Internet or WAN links do not have to be treated equally. An administrator can define a preferred or primary link and designate another link as secondary or backup according to application requirements, link quality, cost, bandwidth, or operational policy.
For delay- and packet-loss-sensitive services such as voice and video, a higher-quality link can be configured as the primary path and another link as the backup. If the primary link no longer satisfies the configured SLA thresholds, traffic can be dynamically switched to a better path. Huawei's material explicitly describes primary and secondary link selection based on SLA and also presents load-balancing-based steering as a separate option.
Load balancing is useful when an enterprise wants to utilize the bandwidth of multiple links concurrently.
Priority-based active/standby forwarding is preferable when one provider offers better quality or when one circuit should be reserved for critical services. Intelligent traffic steering can additionally consider application priority and current bandwidth utilization. Therefore, multiple links can be prioritized, load-balanced, or used in a policy-controlled combination, making option B correct.
NEW QUESTION # 34
Intelligent policy recommendation can achieve network-level load balancing.
Answer: B
Explanation:
The statement is true. Intelligent policy recommendation does not consider only the traffic load of an individual interface or device. iMaster NCE-Campus obtains network topology, application, link-quality, bandwidth-utilization, and traffic-distribution information from multiple devices. It can then recommend or orchestrate policies that distribute traffic across the network's available paths and resources.
For example, when multiple WAN links have the same priority and satisfy an application's SLA requirements, per-flow load balancing can distribute different application flows among those links.
Bandwidth-proportional balancing can also account for differences in link capacity, preventing a lower- bandwidth link from being overloaded. Huawei explains that load-balancing-based traffic steering can fully utilize multiple links and distribute flows across links meeting the required SLA.
Because iMaster NCE-Campus centrally manages CPEs and uniformly orchestrates service intent across the overlay network, recommendations can be evaluated from a network-wide perspective instead of through isolated local decisions. Therefore, intelligent policy recommendation can implement network-level load balancing.
NEW QUESTION # 35
In hierarchical networking, which of the following devices is used for communication between different areas?
Answer: C
Explanation:
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.
NEW QUESTION # 36
Which of the following slicing modes are supported?
Answer: A,B,C,D
Explanation:
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.
NEW QUESTION # 37
On a campus fabric network, which of the following methods can be used for non-authenticated terminals to access a VN?
Answer: D
Explanation:
Non-authenticated terminals can access a virtual network by using statically configured VLANs. Such terminals may include printers, cameras, sensors, industrial devices, and other dumb terminals that cannot perform 802.1X, Portal, or comparable interactive authentication. Their access interfaces and service VLANs are therefore configured in advance and mapped to the required VN.
Dynamic VLAN authorization requires a completed authentication or identification process. Normally, an authentication server returns a VLAN or other authorization attribute after validating the user or terminal.
Because the question specifically refers to non-authenticated terminals, dynamically authorizing a VLAN is not the applicable mechanism. The wired-mode and wireless-mode authorization options are likewise associated with authentication-based policy delivery rather than unconditional VN access.
Huawei's VN design guidance states that LAN-side physical interfaces and VLANs are assigned to the appropriate departments or services and then associated with corresponding VRFs or VNs. It also explains that a department may use an independent physical interface or share an interface while maintaining isolation through VLANs. Therefore, configuring a static VLAN is the correct method.
