Telephonic interview recently held for TCS for the position of L2/L3 developer.
1. Briefly introduce yourself and about current project.
2. Let’s we have topology where host is moving (mac), so how we can manage and control it.
3. While implementing the feature <I just mention about the feature implementation> what are the basic issue you faced, and how you resolve it.
4. If in mac address table mac entry for host A is exist as both static and dynamic, what will happen when pkt will receive at switch. Have you observed such scenario?
5. What all are the step will performed when switch received first pkt from Host A.
6. Do you know LACP. What is difference in LACP/LAG.
7. Can you tell me how link aggregation mention in Broadcom.
8. What are the type of IPC used in your project?
9. How to create message queue, what are the field will be required. Then how to protect. Can we not achieve it by pipe.
10. Can you tell me process memory layout in linux.
11. How do u rate yourself in c in scale of 5.
12. Which one is efficient in 2D array or array of pointer.
13. Can you just tell how to write “Const char pointer”. If I want to have const data.
14. Can you give example of stack overflow, another example then calling main function inside main().
15. Have you used call back function, what will be the prototype of it.
16. Can you just tell me how to write Array of function pointer returning int pointer.
17. What is dangling pointer.
18. If ptr is pointer and pointing to some memory, doing ptr++ five time and then freeing the ptr what will be the issue here.
