1.VXLAN uses MAC-in-UDP encapsulation to extend Layer 2 networks. It encapsulates Ethernet frames
into IP packets for routing, without considering the MAC addresses of VMs. In addition, routed networks
are not limited by the network architecture and support large-scale scalability. VM migration through
routed networks is also not limited by the network architecture.
A. True
B. False
Answer: A
2.The free mobility solution allows a user on a campus network to obtain the same network access policy
regardless of the user's location and IP address. When configuring a policy, the administrator does not
need to pay attention to the IP address ranges of different users, but only needs to focus on the logical
access relationships between users and servers.
A. True
B. False
Answer: A
3.What are the characteristics of Segment Routing?
A. Its deployment is dependent on the controller.
B. It introduces the source routing mechanism conforming to SDN.
C. Its deployment is dependent on LDP and RSVP.
D. It reduces the number of protocols and extends IGP/BGP to support label distribution without
depending on LDP or RSVP.
Answer: B,D
4.If only one firewall is deployed at the egress of the network, a failure on the firewall will affect services
on the entire network. To improve network reliability, you can deploy two or more firewalls and set up a
stack system. Member firewalls do not need to be managed independently. You only need to configure the
stack system.
A. True
B. False
Answer: A
5.Which of the following statements are true about the underlay and overlay concepts on a data center
network? (Select all that apply)
A. After implementing overlay technology, there is no need to deploy routing protocols or static routes on
the underlay network.
B. An underlay network is a bearer network consisting of various physical devices, such as switches and
VAS devices.
C. Overlay technology is a tunneling method that encapsulates service packets and transmits them
transparently over the underlay network, with the origin recovered after reaching their destination.
D. Overlay is a software-defined logical network built on the underlay network using VXLAN.
Answer: B,C,D

the interconnection between branch campuses and between branches and the HQ or DCs. With
5D-WANfunctions integrated, the solution provides two WAN interconnection models: static IPsec VPN
and SD-WAN interconnection.
A. True
B. False
Answer: A
7.In the NAC solution, which of the following authentication modes does not require users to install any
client software and is applicable to scenarios where dumb terminals such as IP phones and printers need
to access the network?
A. 802.1X authentication
B. Wireless authentication
C. Portal authentication
D. MAC address authentication
Answer: D
8.Which of the following technologies implements inter-device link aggregation, and can be used to build
an active-active system to provide traffic load balancing and backup protection?
A. Eth-Trunk
B. Stack
C. M-LAG
D. LLDP
Answer: C
9.Which of the following are core capabilities of Huawei's data center network solution? (Select all that
apply)
A. Ultra-stable reliability: all-scenario assurance, sustainable computing power
B. One network for diverse computing: zero service interruptions
C. One map for intelligent O&M: zero management concerns
D. One platform for simplified deployment: zero configuration errors
Answer: A, B, C, D
10.Which of the following statements is false about Huawei WAN solution's capabilities of convergence &
wide coverage and high transmission capacity?
A. Full-rate interfaces ranging from 64 kbps to 400 Gbps
B. Wired + wireless coverage in any place and scenario
C. Full-rate interfaces ranging from 64 kbps to 800 Gbps
D. SRv6 + mobile phone-based deployment, enabling one-click provisioning of new services
Answer: C
11.In the past, network quality evaluation mainly focused on KPIs such as data transmission bandwidth,
delay, and jitter. Now, network quality evaluation shifts its focus to service experience assurance.

domain listed in?
A. Niche Players
B. Leaders
C. Challengers
D. Visionaries
Answer: B
14.Huawei Wi-Fi 7 stands out for exclusive Wi-Fi Shield technology. Specifically, the AP sends extra
interference signals as noise to ensure that only the target station (STA) can accurately receive data
packets and signals cannot be demodulated at other locations. This prevents malicious users from
intercepting the packets, ensuring campus network security.
A. True
B. False
Answer: A
15.In Huawei's data center network solution, which technology is used to implement unified display of
physical and logical networks for heterogeneous DCs and multi-vendor co-maintenance based on
cross-DC heterogeneous interconnection?
