Exam 200-201 topic 1 question 311 discussion

D. All Frames from No. 20061 to 20064 Here's why: Frame 20061: This frame shows the beginning of a TCP reassembled PDU (Packet Data Unit) with a length of 60512 bytes. This suggests that a file transfer is starting. Frame 20062: This frame continues the reassembled PDU, indicating that the file transfer is ongoing. Frame 20063: This frame shows the end of the reassembled PDU with a "TCP segment of a reassembled PDU" label, confirming that the file transfer is complete. Frame 20064: This frame shows a 75-byte payload identified as "Protected Payload (KPO), DCID-094e3bea2bcfbcce". This suggests that the extracted file might be encrypted or obfuscated in some way. Frames 20065 and 20066 show subsequent traffic related to HTTP and QUIC protocols, but not directly related to the file transfer initiated in frame 20061. Therefore, all frames from 20061 to 20064, including the reassembled PDU and the protected payload, are likely to contain the extractable file.
