When D reaches B, which of the following IP header field(s) may be different from that of the original datagram D? TTL Checksum Fragment Offset $\text{i}$ only $\text{i}$ and $\text{ii}$ only $\text{ii}$ and $\text{iii}$ only $\text{i, ii}$ and $\text{iii}$ Computer Networks gatecse-2014-set3 computer-networks ip-packet normal + – go_editor asked Sep 28, 2014 edited Jun 26, 2018 by Pooja Khatri go_editor 16.2k views answer comment Share Follow See all 9 Comments See all 9 9 Comments reply Show 6 previous comments Amcodes commented Nov 9, 2020 reply Follow Share The subjects where most Ambiguous questions are asked is Computer Networks! 1 votes 1 votes ytheuyr commented Dec 30, 2020 reply Follow Share @Amcodes, totally right! Even for GATE standards these are ridiculous 0 votes 0 votes shashankrustagi commented Jan 15, 2021 reply Follow Share This is not at all ambiguous, as JASHAN said, this checks your aptitude about the subject Destination is not exceptional, it changes the fragmentation offset, so yes, offset can be changed so smart na this is computer science, here you will find the most beautiful questions framed by brilliant and sophisticated minds of IITs and IISC professors 3 votes 3 votes Please log in or register to add a comment.
0 votes 0 votes All the three will be different as TTL is changed at every router Checksum changes if data travels to various routers Also, Fragment offset depends on MTU of different intermediate routers. Source address remains the same. shashankrustagi answered Aug 5, 2020 shashankrustagi comment Share Follow See all 0 reply Please log in or register to add a comment.
