Question #81
In solution C1R19C10, which of the following functions cannot be automatically deployed through underlay?

- B . Internet address
- C . Routing interoperability
- D . Divide routing areas
Question #82
In WLAN scenario, among the four service flows in EDCA, ( ) have the highest priority:
- A . AC_Vl
- B . AC_bk
- C . AC_BE
- D . AC_vo
Question #83
What should the customers do if they want to delete a configuration delivered to the device through NCE-Campus and manually delete the command line on the device?
- A . Just delete it directly on NCE-Campus
- B . Add the command line on the device and delete it through NCE-Campus
- C . No other operations are required, NCE-Campus will perform reconciliation
Question #84
If the device suddenly goes offline during the configuration delivery process, what error message may be displayed in the configuration results?
- A . Configuration service exception.Contact maintenance engineer (netconf communication failed)
- B . Service process failed
- C . The service is abormal
- D . Unrecongnizeinformation
Question #85
Regarding the description of the dual-Border and WAC interconnection design of the campus distributed gateway, which is incorrect?
- A . In the Overlay interworking solution, it is recommended to run VRRP on Vbdif between the two Borders, and the VRRP virtual address serves as the gateway for wireless users;
- B . When wireless centralized forwarding is used, management IP interoperability and service VLAN interoperability are required between WAC and Border, that is, Underlay and Overlay need to be opened;
- C . When performing wireless local forwarding, only the management IP needs to be communicated between WAC and Border, that is, Underlay is connected;
- D . Supported networking: WAC dual-machine hot backup (VRRP dual-machine hot backup or dual-link hot backup), and dual-Border port sub-type networking, dual-machine VRRP hot backup is recommended; in multi-campus interconnection LAN-WAN integration scenarios, refer to the following topology
Question #86
In a multi-campus interconnection LANWAN scenario, refer to the following topology campus topology. Which of the descriptions about the design and deployment of the dual-gateway Interlink solution is incorrect?
- A . Interlink serves as the interconnection port of dual gateway devices and provides forwarding of business (VPN) traffic between devices through sub-interfaces.
- B . Complete the synchronization of dual-gateway device information through the Interlink control sub-interface: such as synchronization and backup of application identification results, synchronization and backup of overlay connection information and connection quality information, etc.
- C . Interlink can be interconnected using direct links. When the site business traffic is large and the CPE port resources are sufficient, it is recommended that Interlink adopts Eth-trunk link.
- D . Interlink cannot borrow the Layer 2 service interface on the CPE LAN side
Question #87
Regarding the statements about campus NCE user access authentication, which is incorrect?
- A . The authentication method supports Portal authentication, MAC authentication, and 802.1X authentication.
- B . Portal page customization is not supported, but docking with third-party Portal servers is supported.
- C . Authentication data is transmitted using HTTP2.0 and Radius protocols, and configuration data is transmitted using Netconf protocol.
- D . Support docking with social media such as WeChat
Question #88
S switch V600R022 version, regarding the IPV6 RGuard implementation description, the incorrect one is ().
- A . RA messages can carry a lot of network configuration information, including key network configuration information such as the default router, network prefix list, and whether to use a DHCPv6 server for stateful address allocation. The attacker modifies the network configuration of the user’s host by sending forged RA messages, making it impossible for legitimate users to communicate normally. IPv6 RGuard provides a defense mechanism against RA message attacks, which can effectively prevent such network attacks.
- B . Configure the user (host) or router (router) role for the interface, and the device then chooses to forward or discard RA messages based on the interface role.
- C . If it is determined that the interface is connected to a user host, configure the interface role as user (host); if it is determined that the interface is connected to a router, the administrator can configure the interface role as router (router) according to the interface in the network. Version 22.0 also supports policy-based filtering of ND packets.
- D . Version 22.0 also supports policy-based filtering of nd packets.
Question #89
Regarding the description of the WLAN network planning solution for the one-to-two scenario of a dormitory/hotel with a bathroom at the door, the correct one is ().
- A . Select the butterfly wing wave AP wall-mounted installation in the bathroom corner, with a height of 2.2~2.5m. A single AP covers the left and right rooms.
- B . The AP fixes the radio frequency power and configures the maximum EIRP value to improve downlink coverage in the wall-through room. The worst 5G downlink RSSI is -65dBm, and the worst uplink RSSI is -80dBm.
- C . Separately deploy indoor omnidirectional APs (2*2 models such as 5761-11) in the corridor to ensure roaming continuity. The bathroom relies on 5G for coverage and turns off 2.4G.
- D . The bathroom relies on 5G for coverage and turns off 2.4G
Question #90
In the campus SDN solution, which statement is wrong about the distributed gateway solution?
- A . In distributed gateway-VxLAN to access, independent AC scenarios, local forwarding mode deployment is not recommended for wireless traffic.
- B . Distributed gateway-VxLAN to access, independent AC scenario, enter VN from edge, execute business mobility policy on edge (edge needs to subscribe to IP-Group service), the current solution supports automated deployment.
- C . The VTEP device is both an L2 gateway and an L3 gateway. Non-gateway nodes are not aware of VXLAN tunnels and only serve as forwarding nodes for VXLAN packets.
- D . In the distributed gateway-VxLAN to aggregation, on-board AC scenario, the accompanying policy for wireless traffic services is executed on the edge, and tunnel forwarding is recommended.
