- C. Layer 3 exclusive egress
- D. Layer 2 exclusive egress
Answer: A,B,C
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
CloudCampus virtualized campus networks support multiplefabric egress modesto connect VXLAN fabrics to external networks. These modes determine how traffic exits the fabric and whether egress resources are shared among multiple virtual networks.
Layer 3 shared egressallows multiple VNs to share the same Layer 3 egress interface, improving resource utilization and simplifying external connectivity.Layer 3 exclusive egressdedicates an independent Layer 3 interface to a specific VN, providing stronger isolation and higher security.
Layer 2 shared egressenables multiple VNs to access an external Layer 2 network through a shared interface. This mode is commonly used when the external network does not support Layer 3 integration.
Layer 2 exclusive egressis not supported in the CloudCampus solution because Layer 2 resources are typically designed to be shared to optimize scalability and simplify deployment.
Therefore, the correct answers are A, C, and D.
NEW QUESTION # 46
Network admission control (NAC) needs to be deployed on the network shown in the figure. Drag a proper authentication mode to each authentication point.
Answer:
Explanation:
Explanation (Based on HCIP Datacom Campus Network Design)
* Position 1 # 802.1X AuthenticationThis authentication point corresponds to aPC connected to an access switch. PCs typically support 802.1X clients, making802.1X authenticationthe preferred and most secure method for wired user access. It provides strong identity-based access control using a RADIUS server.
* Position 2 # Portal AuthenticationThis point representswireless user access. Portal authentication is commonly used for wireless terminals, especially guest or mobile users, where browser-based authentication is required. Users authenticate through a web page redirected by the access device.
* Position 3 # MAC Address AuthenticationThis point corresponds tonon-802.1X-capable terminals, such as IP phones or printers. These devices cannot initiate 802.1X or Portal authentication, soMAC address authenticationis used to identify and authenticate them based on their MAC addresses.
This authentication deployment aligns with Huawei NAC best practices:
* 802.1X for capable wired terminals
* Portal for wireless or guest access
* MAC authentication for dumb or IoT devices
NEW QUESTION # 47

- A. Automatically selects the encryption algorithm; it is not possible to manually specify the national standard encryption algorithm.
- B. Specify the encryption algorithm as SM4 in the SD-WAN tunnel configuration.
- C. Unencrypted tunnel data, relying solely on MPLS label hiding.
- D. It consistently uses international encryption algorithms (such as AES) and does not support Chinese national encryption algorithms.
Answer: B
NEW QUESTION # 48
(The Huawei CloudCampus Solution supports various rate limiting modes for wireless users in small- and medium-sized campus scenarios. Which of the following modes is suitable for refined traffic control of each user?)
- A. ACL-based rate limiting
- B. SSID-based rate limiting
- C. User-based rate limiting
- D. Radio-based rate limiting
Answer: C
Explanation:
In Huawei CloudCampus wireless solutions for small- and medium-sized campus networks,refined traffic controlmeans the ability to precisely limit and manage bandwidth consumption at theindividual user level.
Among the available rate limiting modes,user-based rate limitingis specifically designed to meet this requirement.
User-based rate limiting applies bandwidth control policiesper authenticated user, regardless of which SSID, AP, or radio the user is connected to. This allows administrators to ensure fair bandwidth allocation, prevent a single user from monopolizing wireless resources, and provide differentiated service levels for different user roles, such as employees, guests, or VIP users. This fine-grained control aligns with identity-based access and policy management promoted in HCIP Datacom Campus Network design.
In contrast,SSID-based rate limitingcontrols bandwidth at the service level. It limits total traffic for an entire SSID, which affects all users connected to that SSID collectively, rather than individually.Radio-based rate limitingcontrols bandwidth per radio interface, focusing on wireless resource optimization instead of user- level fairness.ACL-based rate limitingis mainly used for traffic classification and control in wired or advanced scenarios and is not suitable for per-user refined wireless traffic control in CloudCampus WLAN deployments.
Therefore, when the requirement is refined traffic control foreach individual wireless user,user-based rate limitingis the most appropriate and effective option. Hence, the correct answer isA.
NEW QUESTION # 49
(Which of the following is not an advantage of Huawei CloudCampus solution?)
- A. Supports plug-and-play of devices
- B. Unified management of Huawei switches, routers, and storage servers
- C. Supports free mobility
- D. Supports automatic deployment of physical networks
Answer: B
Explanation:
Huawei CloudCampus is an intelligent campus network solution designed to simplify deployment, improve O&M efficiency, and enhance user experience through cloud-based and automated technologies. Its advantages mainly focus onnetwork automation, unified management of campus network devices, and intelligent services, rather than full IT infrastructure management.
Option A is a core advantage of CloudCampus. Through cloud-based controllers and automation technologies, CloudCampus supportsautomatic deployment of physical networks, reducing manual configuration and shortening service rollout time.
Option B is also an important advantage. CloudCampus supportsplug-and-play of devices, where network devices can automatically go online, download configurations, and complete provisioning after being powered on and connected, significantly reducing on-site workload.
Option D is another key feature. Cloud Campus supportsfree mobility, allowing users to roam across different access points or areas while maintaining consistent network access policies and service experience, which is especially important in modern wireless campus environments.
Option C isnot an advantageof the Huawei Cloud Campus solution. Cloud Campus focuses on unified management ofcampus network devicessuch as switches, routers, and wireless devices. It does not provide unified management forstorage servers, which fall outside the scope of campus network management and belong to data center or IT infrastructure management solutions.
Therefore, unified management of Huawei switches, routers, and storage servers is not an advantage of the Cloud Campus solution.
NEW QUESTION # 50
(On a VXLAN-based virtualized campus network, terminals communicate with each other through VXLAN tunnels. When the campus network needs to communicate with external networks, the data must pass through border nodes.)
- A. FALSE
- B. TRUE
Answer: B
Explanation:
Comprehensive and Detailed Explanation (200-250 words):
In a VXLAN-based virtualized campus network, user terminals located in different access locations communicate with each other overVXLAN tunnelsestablished between VXLAN Tunnel Endpoints (VTEPs).
These VXLAN tunnels form the overlay network, which abstracts the physical underlay and enables flexible Layer 2 and Layer 3 connectivity across the campus.
When communication is confined within the virtualized campus network, traffic remains inside the VXLAN overlay and is encapsulated and forwarded between VTEPs. However, when users or services inside the VXLAN network need to accessexternal networks, such as traditional IP networks, the Internet, or data centers that do not support VXLAN, traffic must exit the VXLAN overlay. This function is performed by border nodes.
Border nodes act as the boundary between the VXLAN overlay and non-VXLAN networks. They are responsible for VXLAN encapsulation and decapsulation, routing between VXLAN segments and external networks, and enforcing security and policy controls at the network edge. According to HCIP Datacom Campus Network architecture principles, all traffic entering or leaving the VXLAN-based campus must pass through border nodes to ensure proper routing, policy enforcement, and service control.
Therefore, the statement is TRUE, and option A is correct.
