A.When the NAT Server is not configured with no-reverse, it can perform NAT conversion in both directions. Policy-based destination NAT can only perform one-way NAT conversion.

B.The NAT Server has a higher priority than the policy-based destination NAT. After the first packet reaches the firewall, it is first processed by the NAT Server and the Server map table is searched.
If the Server map table cannot be found, the policy-based destination NAT is then performed.

C.The server-map table is created after the NAT Server is configured, but the destination NAT is not created.

A.The provincial metropolitan area network and the provincial-municipal wide area network are an independent autonomous domain, each municipal metropolitan area network and the city-county wide area network are an independent autonomous domain, and the county metropolitan area network is an independent routing area.

B.In municipal autonomous regions, city and county wide area networks and city metropolitan areas are divided into IS-IS Level 2.

C.In provincial autonomous regions, provincial wide areas, metropolitan areas, and ground equipment in various cities (depending on the situation, there may be no ground equipment if the conditions are not met), divide an IS-IS Level2 area.

D.Each county has an independent AS in the urban area, and the unified planning is IS-IS Level 2.

A.True

B.False

A.If the walls of school classrooms are made of reinforced concrete, the signal attenuation will be greater. It is best to measure the attenuation during the survey. In teaching buildings, attention should be paid to the location of weak rooms.

B.The main load-bearing columns and partitions of the office survey affect the coverage. If it is an integral suspended ceiling, the AP should be placed near the maintenance port as much as possible. If it is a metal suspended ceiling, you can choose to place the AP under the ceiling or wall-mount it.

C.The on-site environment of the stadium is complex and wiring is difficult. Therefore, the weak current room and wiring must be confirmed with the property owner. If the distance is too far, you may need to consider adding an external switch. The survey should focus on the mutual interference between APs and the installation method.

D.The ward inspection scenario has high requirements for coverage field strength, roaming effect, and bandwidth requirements. At the same time, attention needs to be paid to interference from medical equipment or areas where Wi-Fi signals are not allowed.
