What is the primary purpose of a firewall in a network?

To amplify signals over long distances

To assign IP addresses to devices

To filter traffic based on security rules

To connect different networks together

A security manager is reviewing a network architecture where a web server must accept HTTPS connections from the internet and also query a backend database. The manager wants to ensure that the web server can establish the TLS session and that the database query is encrypted. Which statement correctly describes the layers involved?

The database query is automatically encrypted because it travels over the same physical link as the HTTPS session.

HTTPS uses UDP for faster handshakes, and the database query is protected by the same TLS session.

TLS operates at the transport layer, so the web server must use TCP port 443 for the HTTPS session.

TLS is an application-layer protocol, so the web server must use HTTP port 80 for encrypted traffic.

A network manager is evaluating monitoring tools. The team needs to detect abnormal traffic patterns, identify the source of a suspected denial-of-service attack, and retain data for forensic analysis. The budget is limited, and the team has no dedicated security staff. Which approach is most effective?

Use a simple SNMP polling tool to monitor interface utilization

Deploy a flow-based monitoring system (e.g., NetFlow) on the core router

Install a full packet capture appliance at every access switch
