Local PC 10.0.3.35/24
Default Gateway 10.0.3.1
Remote Server 10.0.5.250/24
You then conduct the following tests from the offending Local PC.:
Ping 127.0.0.1 ? Successful
Ping 10.0.3.35 ? Uuccessful
Ping 10.0.3.1 ? Unsuccessful

ipx network 4a
ipx access group 800 out
interface ethernet1
ipx network 3d
interface ethernet2
ipx network 5c
access list 800 permit 3d 4a
which two actions result from implementing this configuration? (Choose two)
A.IPX network 5c will not receive any traffic
B.Traffic from network 3d for network 4a will be forwarded out e0
C.Traffic from network 4a for network 3d will be forwarded out e0
D.Traffic from network 3d destined for network 4a will be forwarded out e2 E.The access list is applied to an outgoing interface and filters outbound traffic
