Huawei H19-301_V4.0-ENU Dumps (V8.02) – The Latest Guide for Your HCSA-Presales-IP Network V4.0 Exam Preparation

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.

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.

3. What are the characteristics of Segment Routing?

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.

5. Which of the following statements are true about the underlay and overlay concepts on a data center network? (Select all that apply)

6. The campus WAN interconnection solution is a sub-solution provided in the Cloud Campus Solution for 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.

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?

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?

9. Which of the following are core capabilities of Huawei's data center network solution? (Select all that apply)

10. Which of the following statements is false about Huawei WAN solution's capabilities of convergence & wide coverage and high transmission capacity?

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.

Which of the following are included in this regard? (Select all that apply)

12. In Huawei's data center network solution, the all-scenario iReliable technology provided by the high-reliability CloudEngine series switches implements three-level fast switchover, ensuring zero service interruptions. M-LAG achieves link-level high reliability with fast link switchover upon failures.

13. Which of the following quadrants of the 2024 Gartner® Magic Quadrant™ was Huawei's campus domain listed in?

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.

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?

16. Which of the following are three types of experience upgrade that Huawei High-Quality 10 Gbps Campus Network Solution brings? (Select all that apply)

17. Which of the following Huawei campus switches is the highest-density fixed switch in the industry?

18. Huawei's high-quality 10 Gbps campus network is experience-centric, providing high-quality network services for various industries based on three types of experience upgrade.

19. Which of the following are involved in Huawei's intelligent converged scheduling technology? (Select all that apply)

20. Huawei's innovative VIP user assurance solution utilizes the unique VIP FastPass and per-packet power control technologies to significantly increase the network bandwidth of VIP users.

21. Which of the following statements is false about Huawei CloudEngine S6750-S series switches?

22. Which of the following are the highlights of Huawei CloudEngine S16700 series switches? (Select all that apply)

23. The high-quality experience assurance card on Huawei CloudEngine S8700 is the core hardware of switches in the centralized application experience upgrade solution.

24. A higher antenna gain indicates stronger signals and wider coverage. Therefore, an AP with a higher antenna gain is preferred in allowed countries.

25. Which of the following statements is false about Huawei's rail transportation wireless backhaul solution?

26. Huawei's hybrid cable 2.0 supports ultra-long-distance data transmission and power supply. The PoE+ power supply distance can be extended to 600 m.

27. Which of the following statements is false about Huawei's outdoor Wi-Fi APs?

28. In the latest-generation WPA3 encryption standard, the key length is 192 bits, making WPA3 more secure than WPA2.

29. Which of the following technologies are advantages of Huawei Wi-Fi?

30. Which of the following is not a factor that affects the wireless rate (throughput) of a Wi-Fi AP?

31. Huawei AirEngine 8771-X1T is Huawei's first Wi-Fi 7 AP with an in-house chip, providing a rate of up to 18.67 Gbps.

32. Which of the following are scenarios for using high-reliability converged gateway NetEngine AR8700-8?
