A technician is tasked with using ACLs to secure a router. When would the technician use the remark configuration option or command?
- to restrict specific traffic access through an interface
- to add a text entry for documentation purposes
- to identify one specific IP address
- to generate and send an informational message whenever the ACE is matched
Answers Explanation & Hints: The remark configuration option or command is typically used by a technician to add a text entry for documentation purposes.
When configuring Access Control Lists (ACLs) to secure a router, the remark command can be used to add comments or descriptions to individual lines of the ACL for the purpose of documenting what each line is meant to do. This can help other network administrators understand the purpose of the ACL and make changes or troubleshoot issues with it more easily.
The other options you listed do not relate to the use of the remark command. To restrict specific traffic access through an interface, the technician would typically use ACL rules to permit or deny traffic based on criteria such as source IP address, destination IP address, protocol type, and port number. To identify one specific IP address, the technician may use an ACL rule that matches that IP address in either the source or destination field. To generate and send an informational message whenever the ACE is matched, the technician would use the logging command in conjunction with the ACL rule.
