H12-351_V1.0 Exam Dumps - Huawei Certification Questions and Answers

Attack defense is a feature that allows APs to analyze the contents and behaviors of incoming packets on ports to determine whether packets have attack characteristics. The APs then take defense measures on the packets that have attack characteristics, such as discarding them or limiting their rate. Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.

Broadcast address is not an IPv6 address type. IPv6 does not support broadcast addressing, but uses multicast addressing instead. The other options are valid IPv6 address types. Unicast address identifies a single interface, multicast address identifies a group of interfaces, and anycast address identifies multiple interfaces but delivers packets to only one of them.

An AP may preferentially use the BTM mode to steer some STAs that are compliant with 802.11v protocol. BTM stands for BSS Transition Management, which is a feature defined in 802.11v protocol that allows an AP to send a request to a STA to switch to another BSS.

According to the Huawei documents and resources, the HLD phase is the high-level design phase of a WLAN project. It involves the following items:

• Capacity planning: Determines the number and types of devices required for the WLAN network based on the customer’s requirements and network scale.
• Network design: Designs the network topology, IP addressing scheme, VLAN division, security policies, and other network parameters for the WLAN network.
• Deployment planning: Plans the deployment sequence, schedule, resources, and risks for the WLAN project.

AP position planning is not involved in the HLD phase. It is part of the LLD phase, which is the low-level design phase of a WLAN project. It involves the detailed design of AP positions, antenna types, channel allocation, power adjustment, and other wireless parameters for the WLAN network. Therefore, C is the correct answer.

C is false because HTTPS redirection is not required for Portal authentication to work properly.

 In a multicast solution, there must be reachable unicast routes between multicast sources and receivers, because multicast routing protocols use unicast routing information to build multicast forwarding trees.

B is false because only Layer 3 VXLAN gateways need to maintain VBDIF interfaces for inter-subnet communication on a VXLAN network or communication with external non-VXLAN networks. Layer 2 VXLAN gateways do not need VBDIF interfaces.
