質問 # 111
In the SD-WAN framework, which statement about the controller's remote disaster recovery solution is incorrect?
- A. Remote disaster recovery supports disaster recovery and backup capabilities between two clusters. The number of nodes in the primary cluster and the disaster recovery cluster must be consistent.
- B. Huawei SD-WAN controller master-slave solution supports multiple master clusters and multiple backup clusters (only one master cluster and one backup cluster are supported)
- C. The controller's primary and backup clusters run simultaneously. Only the primary cluster can provide normal services to the outside world, while the backup cluster does not. Data in the primary cluster is synchronized to the backup cluster in real time to ensure data consistency.
- D. The controller uses a unified domain name or IP address for northbound and southbound traffic. Tenants and devices access the active controller cluster through the unified domain name or IP address. After a master/slave switchover, traffic automatically switches to the new active cluster.
正解：B

- A. Error
- B. Correct
正解：B
質問 # 113
In which scenarios can only IPSec VPN solution be selected?
- A. Small and micro stores only deploy APAP as the egress gateway
- B. Hub node is a third-party VPN gateway
- C. Have multiple regional/multi-center sites
- D. Multiple VPNs need to be deployed between campuses
正解：C、D
質問 # 114
Which of the following descriptions about POE power supply is incorrect?
- A. Wi-Fi 6 APs must use 802.3bt power supply.
- B. The power supply standard of POE++ technology is IEEE 802.3bt, and the maximum PD power is 81.6W.
- C. The power supply standard of POE technology is IEEE 802.3af, and the maximum power of PD is 12.95w.
- D. The power supply standard of POE+ technology is IEEE 802.3at, and the maximum power of PD is 25.5W.
正解：A

質問 # 118
Huawei SD-WAN mainly establishes data channels through GRE or GRE Over IPsec.
- A. Error
- B. Correct
正解：B
質問 # 119
Which statement is correct regarding the classification of roaming?
- A. Layer 2 roaming: When a user moves between APs, the terminal signal connects from the old AP to the new AP, which is roaming. The service VLAN of the AP remains unchanged before and after roaming, and the corresponding gateway remains unchanged.
- B. Sometimes, a network situation arises where two subnets share the same VLAN ID, but belong to different subnets. To prevent the system from misidentifying inter-subnet roaming as Layer 2 roaming based solely on the VLAN ID, the roaming domain is used to determine whether the devices are within the same subnet. Only when the VLANs and roaming domains are the same does Layer 2 roaming occur; otherwise, it is Layer 3 roaming.
- C. Layer 3 roaming: The service VLANs of the SSIDs before and after roaming are different. The service networks provided by the APs are different Layer 3 networks, corresponding to different gateways. In this case, to maintain the unchanged IP address of the roaming user, it is necessary to migrate the user traffic back to the API of the initial access network segment to achieve cross-VLAN roaming.
正解：A、B、C
質問 # 120
In the VLAN design of a campus network, which of the following considerations is correct?
- A. Typically, a Layer 2 switch uses the VLANIF interface address as the management address. It is recommended that each Layer 2 switch be assigned a separate VLAN to reduce interference.
- B. When planning VLANs, it is recommended to assign VLAN numbers continuously to ensure the rational use of VLAN resources.
- C. It is recommended to reserve a certain number of VLANs to facilitate subsequent expansion.
- D. VLAN division needs to distinguish between service VLAN, management VLAN and interconnection VLAN.
正解：B、C、D
質問 # 121
