No. Concerning yourself with just the outside threats is one-sided - an infected computer could join the network or a networked computer could be infected through means other than the internet itself (like inserting an infected pendrive), and that computer would then become a threat not just to the network behind the firewall, but also the Internet at large.
Monitoring inbound traffic is a way to stop incoming infections, but a firewall should be configured to catch threats inside (and outbound) as well, in order to help stop the infection from spreading when it's already "in".
A firewall policy should not only be concerned with inbound traffic. It should have some measures for outbound traffic so as to offer an all-round protection.
True.

No - firewalls should include rules for both inbound AND outbound traffic to adequately protect networks.

The firewall determines if network traffic should continue on to its destination or be stopped.True (Correct!)False
Simply, NO.Outbound traffic is also important because outbound protection alerts you about doubtful attempts that may try to connect to computers outside your network from within the network. There are legitimate processes on your computer that need to connect to outside machines for different reasons like, for updating, mail services, chat services, etc... But if there is a malware on your computer (Firewalls can't protect you from two things.1. Firewall by-passing.2. Internal threats ) you should be able to prevent it from connecting out to send data or hacker invites.Traffic should be monitored (and even filtered) for connections to odd port numbers. Malware already embedded in your network may attempt to spread or contact a home server with gleaned security data.A quality firewall should allow you to retrieve logs sorted by host name, ip address and port numbers so that spot checks would reveal anomalous in and outgoing activity.

The web traffic on port 80 (http on port 80) of the firewall should be allowed from the Internet to the . Generally, this is done through the rules configuration.
stateful packet inspection
master firewall that all traffic flows through
If the PC from the inside network initiated the connection, then it should be allowed automatically. Firewalls by default allow connections from the inside to complete. Firewalls can block SYN requests from the outside, but in this case, the SYN packet came from the inside - the response would be an ACK to establish the handshake. If you are not getting a response from the outside when trying to connect, perhaps the destination firewall is blocking your attempt.
Use an inbound TCP connection on port 110
