NEW QUESTION # 25
In the High-Quality 10 Gbps Campus Network Solution, which of the following experiences is improved by iMaster NCE-Campus?
Answer: D
Explanation:
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.
NEW QUESTION # 26
On a campus fabric network, which of the following methods can be used for non-authenticated terminals to access a VN?
Answer: A
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.
NEW QUESTION # 27
Which of the following encryption algorithms is used by WPA3?
Answer: C
Explanation:
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.
NEW QUESTION # 28
Which of the following statements are true about traffic encryption on SD-WAN links?
Answer: A,C
Explanation:
Huawei SD-WAN allows encryption to be controlled by virtual network and by specific device relationships.
When encryption is enabled for a VN, the overlay data channels carrying that VN's traffic use IPsec protection across the relevant WAN links. This provides consistent isolation and confidentiality for the department or service represented by that VN.
Encryption can also be enabled between selected devices or sites. In that case, secure data channels are established for traffic exchanged between those specified endpoints, while other device relationships can continue using GRE without IPsec according to their policies.
Application-specific encryption, as described in option C, is not the supported control granularity. Application identification can influence intelligent traffic steering, QoS, and security-policy selection, but it does not mean that only the payload of a selected application is independently encrypted inside an otherwise unencrypted SD-WAN tunnel.
A transport network is an underlay WAN such as MPLS or the Internet. Enabling encryption is an overlay tunnel policy rather than a mechanism that encrypts all traffic belonging to an entire TN. Huawei distinguishes TNs as underlay networks and GRE or IPsec VPNs as overlay data channels. Therefore, only A and B are correct.
NEW QUESTION # 29
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.
