After enabling DHCP on the router RTA, you need to set the address range of the address pool to 192.168.1.0/24, and the default gateway address assigned to the host is 192.168.1.254.
Which of the following configurations can meet these requirements? (multiple choice)

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

A network administrator configured on a router
RIP: rip 1
version 2
network 100.0.0.0
network 8.0.0.0
However, it is found that the RIP route of the opposite end cannot be learned. The administrator needs to enable RIP debugging information on the router. Which of the following configurations can be used to view RIP debugging information on the router?

The WAN links of the customer's two routers MSR-1 and MSR-2 use the PPP protocol, and MSR-1 is required as the primary verifier to verify MSR-2 through CHAP. Then which of the following configurations may be required for MSR-2? (Multiple choice)

The two MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their S1/0 interfaces, and their GigabitEthernet0/0 interfaces are respectively connected to the client hosts HostA and HostB: HostA----GE0/0--MSR-1 --S1/0---------S1/0--MSR-2--GE0/0----HostB
By configuring the IP address and routing, HostA can communicate with HostB in the current network. Now the following ACL configuration is added to the router MSR-1:
acl number 3000
rule 0 deny icmp icmp-type echo
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
firewall packet-filter 3000 inbound
So which of the following statements are correct? (Multiple choice questions)
