A company purchased switches from two manufacturers, A and B, for network engineering implementation. Need to use link aggregation technology between the switches of the two vendors. After consulting the relevant documents, it is found that the switch of manufacturer A does not support the LACP protocol.
In this case, which of the following configuration methods are reasonable? (multiple choice)

The two WAN interfaces S1/0 and S1/1 of the router MSR-1 are connected to the routers MSR-2 and MSR-3 respectively.
At the same time, the Ethernet port of MSR-1 is connected to MSR-4. All four routers have run the RIP protocol and completed routing learning correctly. All routers have started all the features of RIP to prevent loops. At this time, it is found that the MSR If the network 192.168.0.0 on -2 fails, then ______. (Multiple choice)

The correct sequence of the steps in the startup process of detecting the router system is _________. (Fill in the code of each step one by one, there can be no spaces in between, such as: ABCD)

Divide a class B network segment into subnets. If the subnet mask is 19 bits, then the maximum number of hosts that can be accommodated in each subnet is ______. (Please fill in Arabic numerals)

A Layer 3 switch is connected to the GE0/0 interface of the customer's router MSR-1, and this Layer 3 switch is the default gateway for multiple network segments of the customer's office network to which it is connected. MSR-1 is connected to the Internet through the serial port S1/0. The entire network has been interoperable normally, and office network users can access the Internet. Add the following ACL configuration on the router:
firewall enable
acl number 3004
rule 0 deny ip source 192.168.1.0 0.0.0.255
rule 5 permit tcp source 192.168.0.0 0.0.255.255
rule 10 permit icmp
At the same time, ACL 3004 is applied in the inbound direction of GE0/0, then ______. (Multiple choice)
