NEW QUESTION # 39
(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.

NEW QUESTION # 49
(VXLAN identifies tenants using VNIs, which are 24 bits long. A tenant can have one or more VNIs, and VXLAN supports a maximum of 12 million tenants.)
- A. FALSE
- B. TRUE
Answer: A
Explanation:
VXLAN uses theVXLAN Network Identifier (VNI)to identify and isolate virtual Layer 2 or Layer 3 networks in an overlay environment. The VNI field is24 bits long, which allows a theoretical maximum of2²# (approximately 16 million) VNIs. This is a significant improvement over traditional VLAN technology, which supports only 4094 VLAN IDs, and is one of the main reasons VXLAN is adopted in large-scale campus and data center networks.
It is correct thata tenant can be mapped to one or more VNIs. For example, a tenant may use multiple VNIs to represent different broadcast domains or service segments, such as separate VNIs for different subnets or application tiers. However, the statement becomes incorrect when it claims that VXLAN supports a maximum of12 million tenants.
VXLAN does not directly define a fixed maximum number of tenants. VNIs represent virtual networks, not tenants themselves. The actual number of tenants supported depends on how VNIs are allocated and how the network design maps tenants to VNIs. In theory, the upper limit of VNIs is close to 16 million, not 12 million, and the number of tenants is typically much lower and design-dependent.
Therefore, while the description of VNIs being 24 bits long is correct, the conclusion about supporting a maximum of 12 million tenants is incorrect, making the overall statement false.

- C. Edge node caching (caching video streams locally to reduce long-distance transmission latency)
- D. Video traffic priority scheduling (based on DSCP tag priority forwarding of video data packets)

Answer: C,D,E
NEW QUESTION # 51
In Huawei's SD-WAN solution, for the scenario of " branch multi-link (MPLS + Internet + 5G) load balancing", which of the following technologies can "dynamically adjust the traffic allocation ratio according to the real-time bandwidth utilization of the link"?
- A. All traffic is prioritized to use the MPLS link; other links are only used as cold backups.
- B. Dynamic load balancing based on link bandwidth utilization (reducing traffic on links with high utilization and increasing traffic on links with low utilization).
- C. Randomly allocate traffic to each link, without considering bandwidth utilization.
- D. Allocate traffic according to a fixed ratio (e.g., 40% MPLS, 30% Internet, 30% 5G), without adjusting for bandwidth changes.
Answer: B
NEW QUESTION # 52
(As shown in the following figure, R1 and R2 establish an IPsec VPN in ISAKMP mode for communication.
For IPsec proposals on R1 and R2, ESP is used, the encapsulation mode is set to tunnel mode, SHA1 is configured as the authentication algorithm, and AES-256 is configured as the encryption algorithm. In addition, IKEv1 is configured for IKE peers, the main mode is configured for IKEv1 negotiation phase 1, and the PSK Huawei@123 is configured for PSK authentication between IKE peers. For IKE proposals on R1 and R2, SHA1 is configured as the authentication algorithm, AES-256 is configured as the encryption algorithm, and DH group 1 is configured for IKE negotiation. Based on these configurations on R1 and R2, drag the configuration items on the left to the correct locations on the right.)
Answer:
Explanation:
Explanation:
1 #dh group1
2 #main
3 #esp
4 #tunnel
In the IKE proposal, the Diffie-Hellman group defines the key exchange strength used during IKE Phase 1 negotiation, which is whydh group1corresponds to position 1 under the IKE proposal configuration. The exchange-mode mainsetting is part of IKEv1 Phase 1 and therefore correctly matches position 2 under the IKE peer configuration.
For the IPsec proposal, thetransformspecifies the protocol used to protect data traffic; since ESP is explicitly required,espcorrectly maps to position 3. Finally, theencapsulation-mode tunneldefines how packets are encapsulated in IPsec VPNs between gateways, makingtunnelthe correct match for position 4.
This mapping strictly follows HCIP Datacom Campus Network IPsec and IKE configuration logic and aligns with standard Huawei VRP command behavior.
