When a packet is received on an interface with an inbound access list configured, the packets are matched
against the access list to determine if they should be permitted or denied.After this check, the packets are
processed by the routing function.The access list check is always done first.
B, C.The packets are always processed by the inbound access list prior to being routed.
D.All packets are always checked against a specific access list only once.While packets traversing through a
router may be checked against different access lists for each interface and in each direction (inbound and
outbound), each access list is always only consulted once.
