An ACL is applied inbound on a router interface. The ACL consists of a single entry: If a packet with a source address of 192.168.10.45, a destination address of 10.10.3.27, and a protocol of 80 is received on the interface, is the packet permitted or denied?

The ACL (Access Control List) entry is:

This entry permits TCP traffic from the source IP address range 192.168.10.0 to 192.168.10.255 (as indicated by the subnet mask 0.0.0.255) to any destination, as long as the destination port is 80 (which is indicated by eq www, where www represents the well-known port for HTTP).

The packet in question has:

• Source address: 192.168.10.45
• Destination address: 10.10.3.27
• Protocol: 80 (TCP)

Since the packet’s source address falls within the specified range (192.168.10.0 to 192.168.10.255), is using TCP, and is destined for port 80, it matches the criteria set by the ACL entry. Therefore, the packet is permitted.
