The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1, and the switch SWA has the following configuration information:
[SWA] rrpp domain 1
[SWA-rrpp-domain1] control-vlan 4092
If the switch SWA ports Gigabitethernet 1/0/1 and Gigabitethernet 1/0/2 are connected to the RRPP ring, we can know from the above information

XYZ company requires to build its network based on a modular enterprise network architecture. XYZ has a research and development base in Shenzhen and Xi'an, an office building in Beijing and Shanghai, offices with more than 50 people in 23 capital cities, and technicians in 23 provinces on business trips. Due to environmental and cost issues, some offices cannot access the headquarters through dedicated lines or packet-switched wide area network connections. According to these circumstances, the network module that XYZ company should have is _____.

In the network as shown in the figure, the switch SWA is a Layer 2 switch, and the router RTA is the gateway of each PC. The following configuration is made on the router RTA:
[RTA]interface Ethernet 0/0
[RTA-Ethernet0/0]ip address 10.10.10.1 255.255.255.0
[RTA-Ethernet0/0]interface ethernet 0/0.2
[RTA-Ethernet0/0.2]ip address 20.20.20.1 255.255.255.0
[RTA-Ethernet0/0.2]vlan-type dotlq vid 2
[RTA-Ethernet0/0.2]interface ethernet 0/0.3
[RTA-Ethernet0/0.3]ip address 30.30.30.1 255.255.255.0
[RTA-Ethernet0/0.3]vlan-type dotlq vid 3
After completing the corresponding configuration on the switch SWA, PCA, PCB and PCC can ping their own gateway. The configuration of the switch SWA port Ethernet1/0/4 should be (choose one or more)

As shown in the networking, the switch enables RSTP, and the following statements about its configuration are correct.

The switch SWA uses the factory default configuration. Now the Ethernet 1/0/1 port of the switch SWA should be configured as a trunk port, the PVID is VLAN20, and VLAN10 is allowed. The following configuration process is correct.
