NEW QUESTION 191
The address of the GE0/0 interface of the router MSR-1 is 192.168.100.1/24. This interface is connected to a Layer 3 switch, and this Layer 3 switch is the default gateway for multiple network segments of the customer's office network. 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.
For security reasons, it is necessary to prohibit the client host from pinging the GE0/0 interface of MSR-1, so the following ACL is configured on the router:
acl number 3008
rule 0 deny icmp source 192.168.1.0 0.0.0.255
At the same time, the ACL is applied in the inbound direction of GE0/0. It is found that users on the 192.168.0.0/24 network segment in the LAN can still ping the GE0/0 interface address. According to the above information, _______ can be inferred.
- A. After the shutdown and undo shutdown commands are executed on the interface GE0/0, the 192.168.0.0/24 network segment will not be able to ping the MSR-1 Ethernet interface address.
