An ACL is applied inbound on a router interface. The ACL consists of a single entry: access-list 100 permit tcp 192.168.10.0 0.0.0.255 172.17.200.0 0.0.0.255 eq www . If a packet with a source address of 192.168.10.244, a destination address of 172.17.200.56, and a protocol of 80 is received on the interface, is the packet permitted or denied?

If a packet with a source address of 192.168.10.244, a destination address of 172.17.200.56, and a protocol of 80 is received on the interface, is the packet permitted or denied?
denied
permitted
Explanation: The packet is permitted because it successfully matches every field specified in the Access Control Entry (ACE):
Source Address: The packet's source (192.168.10.244) matches the network 192.168.10.0 with the wildcard mask 0.0.0.255.
Destination Address: The destination (172.17.200.56) matches the target network 172.17.200.0 with the wildcard mask 0.0.0.255.
Protocol and Port: The packet uses protocol 80, which is the numerical equivalent of the www keyword used in the configuration for TCP traffic.
