Part 1: Verify Local Connectivity and Test Access Control List Step 1: Ping devices on the local network to verify connectivity. a. From the command prompt of PC1, ping PC2. b. From the command prompt of PC1, ping PC3. Question: Why were the pings successful?

Step 2: Ping devices on remote networks to test ACL functionality. a. From the command prompt of PC1, ping PC4. b. From the command prompt of PC1, ping the DNS Server. Question: Why did the pings fail? (Hint: Use simulation mode or view the router configurations to investigate.)

b. For an ACL to impact router operation, it must be applied to an interface in a specific direction. In this scenario, the ACL is used to filter traffic exiting an interface. Therefore, all traffic leaving the specified interface of R1 will be inspected against ACL 11. Although you can view IP information with the show ip interface command, it may be more efficient in some situations to simply use the show run command. Question: Using one or both of these commands, to which interface and direction is the ACL applied?
