You need to configure a firewall to allow only secure HTTPS traffic (port 443) to a web server while blocking all other incoming connections. Which level of the TCP/IP protocol stack should the firewall operate at?1.0 MarksNetwork Access Layer (NAL)Internet Protocol (IP)Network Interface Card (NIC)Application LayerTransport Layer

You're managing a virtual private network (VPN) for remote employees. To ensure secure communication, you need to configure the VPN client and server with appropriate ports. Which port(s) should you use for the VPN tunnel?1.0 MarksVPN uses specific protocol ports depending on the chosen protocol (PPTP, L2TP/IPSec, etc.)Any unused port above 1024 can be used for the VPN tunnelThe VPN automatically configures the necessary ports upon setupStandard web ports (80, 443) are sufficient for secure VPN communicationPort forwarding rules specific to the VPN software are needed
