Implementing Cisco IP Switched Networks (SWITCH v2-0) (#503)

Which two statements are true about recommended practices that are to be used in a local VLAN solution design where layer 2 traffic is to be kept to a minimum? (Choose two.)

Routing should occur at the access layer if voice VLANs are utilized. Otherwise, routing should occur at the distribution layer.
Routing may be performed at all layers but is most commonly done at the core and distribution layers.
Routing should not be performed between VLANs located on separate switches.
VLANs should be local to a switch.
VLANs should be localized to a single switch unless voice VLANs are being utilized.
