Correct answer & explanation
✓ipv6 access-list: access-list (IPv4 numbered/named ACL)
IPv6 ACLs use ipv6 access-list instead of access-list; They match on IPv6 source/dest addresses; They support the same permit/deny actions; They can use named entries; They can log matches similarly.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop each IPv6 ACL feature on the left to its matching IPv4 ACL equivalent on the right.
hard- ✓ P1.ipv6 access-list: Equivalent to ip access-list extended in IPv4
- ✓ P2.deny ipv6: Equivalent to deny ip in IPv4 extended ACL
- ✓ P3.permit tcp: Equivalent to permit tcp in IPv4 extended ACL
- ✓ P4.sequence number: Equivalent to sequence number in IPv4 named ACL
- ✓ P5.implicit deny ipv6: Equivalent to implicit deny ip in IPv4 ACL
Why P1: IPv6 ACLs use similar logic but with IPv6-specific syntax: deny/ipv6, permit/ipv6, sequence numbers, and implicit deny.
