Question: In a GSM Public Land Mobile Network (PLMN) with multiple connection elements, each having different information transfer rates, what determines the overall connection type's attribute value according to 3GPP standards?
Option 1: The highest transfer rate among all connection elements.
Option 2: The average of all transfer rates of the connection elements.
Option 3: The lowest transfer rate among all connection elements.
Option 4: The sum of all transfer rates of the connection elements.
Explanation: This is because, according to 3GPP standards, the overall connection type's attribute value is determined by the lowest value of any of its constituent connection elements, ensuring the overall connection is only as strong (or fast) as its weakest link.
