質問 # 42
A network connection is like:
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
Two MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their S1/0 interfaces, and their GE0/0 interfaces are respectively connected to the client hosts HostA and HostB. The IP address of HostA is 192.168.0.2/24, and the address of the S0/0 interface of MSR-2 is 1.1.1.2/30. By configuring other relevant IP addresses and routes, HostA can communicate with HostB in the current network.
Nowadays, the customer requires that HostA is not allowed to log in to the MSR-2 through Telnet at address 1.1.1.2.
So which of the following configurations can meet this requirement? (multiple choice)
- A. Configure the following ACL on MSR-1 and apply it to the inbound direction of GE0/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl-adv -3000]rule 0 deny tcp source 192.168.0.1 0.0.0.255 destination 1.1.1.2 0.0.0.3 destination-port eq telnet
- B. Configure the following ACL on MSR-1 and apply it to the outbound direction of GE0/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl- adv-3000]rule 0 deny tcp source 192.168.0.2 0 destination 1.1.1.2 0 destination-port eq telnet
- C. Configure the following ACL on MSR-1 and apply it to the outbound direction of S1/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl- adv-3000]rule 0 deny tcp source 192.168.0.2 0 destination 1.1.1.2 0.0.0.3 destination-port eq telnet
- D. Configure the following ACL on MSR-1 and apply it to the inbound direction of S1/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl- adv-3000]rule 0 deny tcp source 192.168.0.1 0.0.0.255 destination 1.1.1.2 0 destination-port eq telnet
