  • Q5. How does a router routes a packet
  • Ans. 

    A router routes a packet by examining the destination IP address and forwarding it to the appropriate network.

    • The router receives a packet from a device on one of its interfaces

    • The router examines the destination IP address in the packet header

    • The router looks up the destination IP address in its routing table

    • The router forwards the packet to the appropriate interface based on the routing table

  • Answered by AI
  • Q6. How does a router uses longest prefix matching to route a packet
  • Ans. 

    A router uses longest prefix matching to find the most specific route for a packet.

    • The router looks at the destination IP address of the packet

    • It compares the address with the entries in its routing table

    • The router selects the entry with the longest matching prefix

    • The packet is then forwarded to the next hop in that route

    • If there is no matching prefix, the router uses the default route

    • Longest prefix matching ensures ef...

  • Q7. What is page fault
  • Ans. 

    Page fault is an error that occurs when a program tries to access a page that is not currently in physical memory.

    • Occurs when a program tries to access a page not in physical memory

    • Operating system retrieves the page from disk to physical memory

    • Can cause performance issues if it happens frequently

    • Can be caused by insufficient memory or memory fragmentation

  • Answered by AI
  • Q8. How does a page fault is serviced
  • Ans. 

    Page fault is serviced by fetching the required page from disk to memory.

    • When a process tries to access a page that is not in memory, a page fault occurs.

    • The operating system then checks if the page is present in the disk.

    • If the page is not present in the disk, it results in a segmentation fault.

    • If the page is present in the disk, it is fetched to memory and the process continues.

    • The process is then restarted from the

  • Q9. How ping is implemented(told him about the ICMP)
  • Q10. How can you calculate the round trip time and bandwidth of the network using Pin
  • Ans. 

    Calculating round trip time and bandwidth of network using Pin

    • Use Pin to measure the time it takes for a packet to travel from source to destination and back

    • Divide the round trip time by 2 to get the one-way latency

    • Calculate bandwidth by dividing the size of the packet by the one-way latency

    • Repeat the process with different packet sizes to get an average bandwidth

    • Use Pin's built-in tools to analyze the data and generat

  • Answered by AI
  • Q11. Can you measure congestion in the system using Ping and how?
  • Ans. 

    Yes, Ping can be used to measure congestion in the system.

    • Ping measures the round-trip time for packets to travel from the source to the destination.

    • If the round-trip time is high, it indicates congestion in the network.

    • Ping can also be used to measure packet loss, which is another indicator of congestion.

  • Answered by AI
  • Q12. Explain different algorithms that applies in networking domain
  • Ans. 

    Algorithms used in networking include routing, switching, and security protocols.

    • Routing algorithms determine the best path for data to travel between devices on a network.

    • Articulation points are also known as cut vertices.

    • They are significant in network design and analysis as they help identify critical points in the network.

    • Removing an articulation point can cause the network to split into multiple disconnected components.

    • For example, in a computer networ...

  • Q15. You are given an array of 0s, 1s and 2s, you have to sort it. (calculating the number of 0s,1s and 2s is not counted as the solution for this problem)
  • Ans. 

    Sort an array of 0s, 1s, and 2s without counting their occurrences.

    • Use three pointers to keep track of the last index of 0s, 1s, and 2s.

    • Iterate through the array and swap elements to their respective pointers.

    • Time complexity: O(n), Space complexity: O(1).

  • Answered by AI
  • Q16. What is Denial of Service attack and what is its remedy?
  • Ans. 

    A Denial of Service (DoS) attack is an attempt to make a website or network unavailable to users by overwhelming it with traffic.
