Question: In a Policy and Charging Control (PCC) context, what information does the second octet of the ToS-Traffic-Class AVP (AVP code 1014) contain for both IPv4 and IPv6?
Option 1: IPv4 Type-of-Service or IPv6 Traffic-Class value
Option 2: ToS/Traffic Class mask field
Option 3: Packet filter configuration as per TFT specifications
Option 4: Access type indicator (e.g., mobile, WiFi)
Explanation: The correct answer is Option 2 because, according to the specification, the second octet of the ToS-Traffic-Class AVP is dedicated to containing the ToS/Traffic Class mask field. This field is crucial for defining which parts of the Type-of-Service (for IPv4) or Traffic-Class (for IPv6) are relevant for traffic handling decisions in telecom networks, ensuring proper packet prioritization and treatment based on policies set by the network operator.
