A.

The malicious insider attempted to use the Tcpdump tool to sniff traffic on a specific interface. Tcpdump is a command-line tool used to capture and analyze network traffic in real-time. By capturing traffic on a specific interface, the malicious insider could potentially obtain sensitive information that is being transmitted across the network.

Option A, tagged protocols being used on the network, refers to the protocol identification that is used in tagging network traffic. Although Tcpdump can identify the protocols being used on the network, this information alone is not typically considered sensitive information.

Option B, all firewall alerts and resulting mitigations, refers to the alerts generated by a network firewall in response to potentially malicious network traffic. Tcpdump does not capture this type of information, as it is typically handled by the firewall itself.

Option C, tagged ports being used on the network, refers to the identification of network ports being used to transmit data across the network. While this information can be useful to an attacker, it is not typically considered sensitive.

Option D, all information and data within the datagram, refers to the entire packet of data being transmitted across the network. This includes the headers and payloads of the data packet. If the data being transmitted is sensitive or confidential, then capturing this data can be damaging to an organization's security posture.

In conclusion, the malicious insider attempted to obtain all information and data within the datagram by using Tcpdump to sniff traffic on a specific interface.
