14. Frage
Intelligent policy recommendation can achieve network-level load balancing.
Antwort: A
Begründung:
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.
15. Frage
Which of the following encryption algorithms is used by WPA3?
Antwort: A
Begründung:
The intended answer is AES-256. In certification material, this question normally refers to the enhanced WPA3-Enterprise 192-bit security suite, which uses the GCMP-256 data-protection algorithm based on AES-
256, together with stronger integrity and key-management components. AES-512 is not a standardized AES variant, and RC4 is the obsolete stream cipher associated with legacy WEP and TKIP-era protection rather than WPA3.
There is an important technical qualification: WPA3 is a family of certification modes, not one universal cipher suite. WPA3-Personal commonly uses Simultaneous Authentication of Equals for password- authenticated key establishment and requires CCMP-128, which is based on AES-128. WPA3-Enterprise 192- bit mode, however, uses AES-256 in GCM mode. Therefore, the original wording is broader than it should be.
A technically precise version would ask which algorithm is associated with the WPA3-Enterprise 192-bit security suite. Under the intended Huawei examination scope and the supplied single-choice options, option B is correct. That distinction is crucial when interpreting this simplified examination item.
16. Frage
Which of the following statements are true about predefined security zones on a firewall?
Antwort: A,B,D
Begründung:
Huawei firewalls provide four commonly predefined security zones: Local, Trust, DMZ, and Untrust. The Local zone represents the firewall itself, including traffic generated by or destined for the device, and has the highest default security priority of 100. The Trust zone normally represents an organization's protected internal network and has a default priority of 85, not 95. Therefore, option C is false.
The DMZ typically hosts public-facing or semi-trusted resources, such as web, email, and application servers.
Its default priority is 50, placing it between the trusted internal network and the external untrusted network.
The Untrust zone normally represents the Internet or another uncontrolled network and has the lowest predefined priority of 5.
Zone priority expresses the relative security level used to classify inbound and outbound traffic direction; it does not independently permit traffic. Security policies still determine whether matched traffic is allowed or denied. Huawei's SD-WAN design uses Trust and Untrust zones on CPEs, and iMaster NCE can orchestrate the corresponding zones and firewall policies for Internet-access protection.
17. Frage
Which of the following WLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer network?
Antwort: C
Begründung:
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.
18. Frage
Which role supports MRM election?
Antwort: C
Begründung:
MRA, or Media Redundancy Auto-Manager, supports the automatic election of the Media Redundancy Manager in an MRP ring. When several devices are configured with the MRA role, they exchange control information and elect one device to perform the MRM function. The elected MRM supervises the ring, blocks one ring port during normal operation to prevent a Layer 2 loop, detects failures, and changes the forwarding state when the ring becomes open.
An MRC is a Media Redundancy Client. It participates in the MRP ring and forwards MRP control packets, but it does not initiate the automatic manager-election process. MRM represents the operational manager role after election or manual configuration, rather than the role specifically designed to support election. MIM refers to a Media Redundancy Interconnection Manager, which is associated with interconnecting and protecting multiple MRP rings rather than electing the manager within one ring. MRP itself distinguishes the ring manager from ring clients and uses the manager to control ring forwarding and recovery.
