Detailed Explanation:Access ports are configured for a single VLAN and thus send untagged frames by default. Trunk ports, conversely, handle traffic for multiple VLANs, tagging each frame with a VLAN ID. (Reference: HCIA-Datacom Training Material, Switch Port Types and VLAN Tagging)

WEP (Wired Equivalent Privacy) supports open authentication, which allows any client to associate with the network without verifying credentials. This form of authentication is considered insecure by modern standards, as it provides minimal protection for network access. WPA and WPA2 rely on pre-shared keys or 802.1X authentication, which are more secure and do not use open authentication​.

In RSTP, both alternate and backup ports do not forward user traffic, but they can still receive and process BPDUs (Bridge Protocol Data Units). This allows the network to quickly reconfigure if the active path fails, as these ports are already participating in spanning tree calculations​.

Detailed Explanation:Making a call on a landline telephone involves network communication. Though it uses a traditional telephone network (Public Switched Telephone Network, PSTN), the process of sending and receiving voice data through a wired system qualifies as network communication. The voice signals are converted into electrical signals, transmitted over the network, and then converted back into voice signals on the receiving end .
