What is the method used to filter traffic being bridged within a VLAN?

A.
Ethernet maps

B.
router ACLs

C.
VLAN maps

D.
IP ACLs

Explanation:
You can use VLAN ACLs or VLAN maps to provide access-control for all packets (bridged and
routed). You can use VLAN maps to filter traffic between devices in the same VLAN. VLAN maps
are configured to provide access control based on Layer 3 addresses for IPv4. Unsupported
protocols are access-controlled through MAC addresses using Ethernet ACEs. After a VLAN map
is applied to a VLAN, all packets (routed or bridged) entering the VLAN are checked against the
VLAN map.
