Question: In a Mission Critical Data (MCData) scenario, when a user initiates a one-to-one standalone Short Data Service (SDS) transfer using the media plane, how is the target MCData user typically addressed?
Option 1: Using a unique IMSI (International Mobile Subscriber Identity)
Option 2: Utilizing a functional alias that can be shared with other MCData users
Option 3: Through a temporary identifier assigned by the network for each SDS session
Option 4: By broadcasting to all users within the same mission critical group
Explanation: In the context of MCData's one-to-one standalone SDS using the media plane, addressing the target user efficiently and securely is crucial. While IMSI (International Mobile Subscriber Identity) could theoretically be used for addressing, it's not typically shared openly due to privacy concerns. Temporary identifiers might add complexity without providing additional security in this specific use case. Broadcasting is inappropriate for one-to-one communications. Therefore, utilizing a functional alias that can be shared with other MCData users (Option 2) is the most appropriate method as it balances accessibility with the need for controlled sharing within trusted groups, aligning with the principles of mission-critical communications where teams often need to share quick, secure updates.
