Question: What is a major drawback of IP fragmentation in GTP-C, making it inefficient?
Option 1: Duplicate IP headers in each fragment
Option 2: Increased risk of packet loss due to selective retransmission
Option 3: Reduced path MTU discovery capabilities
Option 4: Inability to use IPv6 headers for encapsulation
Explanation: IP fragmentation in GTP-C is inefficient because the complete IP header is duplicated in each fragment, resulting in unnecessary overhead and reduced network performance. This highlights the importance of avoiding fragmentation whenever possible and utilizing path MTU discovery mechanisms to optimize packet transmission.
