Top Select Interview Questions for Network Engineer's!!!

Q16. What are the advantages and disadvantages of the three types of routing tables?
Ans. The three types of routing tables are fixed, dynamic, and fixed central. The fixed table must be manually modified every time there is a change. A dynamic table changes its information based on network traffic, reducing the amount of manual maintenance. A fixed central table lets a manager modify only one table, which is then read by other devices. The fixed central table reduces the need to update each machine’s table, as with the fixed table. Usually a dynamic table causes the fewest problems for a network administrator, although the table’s contents can change without the administrator being aware of the change.

Q17. What is a characteristic of Store and Forward switches?
Ans. They read the entire frame and check CRC before forwarding.

Q18. What is source route?
Ans. It is a sequence of IP addresses identifying the route a datagram must follow. A source route may optionally be included in an IP datagram header.

Q19. What is RIP (Routing Information Protocol)?
Ans. It is a simple protocol used to exchange information between the routers.

Q20. What is SLIP (Serial Line Interface Protocol)?
Ans. It is a very simple protocol used for transmission of IP datagrams across a serial line.
