Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The 'ip access-group' command applies an ACL to an interface in a specified direction.

The 'ip access-group' command is used to apply an ACL to an interface in a specific direction (in or out). It can be applied to both Layer 3 interfaces (routed ports) and SVIs. The ACL must already exist in the configuration. The command does not create the ACL; it only applies it. The 'in' direction filters traffic entering the interface, and 'out' filters traffic leaving.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The 'ip access-group' command applies an ACL to an interface in a specified direction.

    Why this is correct

    Correct because the command syntax is 'ip access-group {acl-name} {in|out}'.

  • The 'ip access-group' command can be applied to both physical interfaces and SVIs.

    Why this is correct

    Correct because it works on any Layer 3 interface, including SVIs.

  • The 'ip access-group' command creates a new ACL if the named ACL does not exist.

    Why it's wrong here

    Incorrect because the ACL must be created separately; the command only applies an existing ACL.

  • The 'ip access-group' command can only filter traffic in the inbound direction.

    Why it's wrong here

    Incorrect because it supports both 'in' and 'out' directions.

  • The 'ip access-group' command is used to apply a CoPP policy to the control plane.

    Why it's wrong here

    Incorrect because CoPP uses 'service-policy' under 'control-plane', not 'ip access-group'.
