Computer Networks And Internet Protocol NPTEL 2023 Week 3 Solutions

This set of MCQ(multiple choice questions) focuses on the Computer Networks And Internet Protocol NPTEL 2023 Week 3 Solutions .

The domain of Internet has grown in a rapid pace from traditional circuit switched and packet switched small scale networks to modern high-speed mobile and wireless Internet. A large number of methods, architectures and designs came up at every protocol level to cop up with the demands for developing a secure and highly dependable information technology infrastructure. The broad objective of the course is to understand – (i) the architecture and principles of today’s computer networks, (ii) the protocols and their functionalities, (iii) the requirements for the future Internet and its impact on the computer network architecture. In this course, we’ll broadly cover the basic TCP/IP protocol stack and touch on the next generation computer networks. We’ll take a top-down approach to cover different protocols at the TCP/IP protocol stack.

Computer Networks And Internet Protocol - Week 8 Assignment 8 | NPTEL | JAN 2023

Computer networks and internet protocol - week 8 | assignment : answer with explanation.

Computer Networks And Internet Protocol - Week 8 Assignment 8  NPTEL  JAN 2023

How Many classes exist in classful addressing of IPs ?

b. 5 The classful addressing of IP addresses is an older addressing scheme that has been replaced by the classless addressing scheme. However, the classful addressing scheme defined five classes of IP addresses, which are commonly known as Class A, Class B, Class C, Class D, and Class E.

What is an IP routing table used for in computer networks?

B. To identify the next hop for an IP packet

What is the difference between intra-domain routing and inter-domain routing?

A. Intra-domain routing is used within a single network, while inter-domain routing is used between different networks. Intra-domain routing, also known as Interior Gateway Protocol (IGP), is used to exchange routing information within a single autonomous system (AS) or network. Examples of IGP protocols include OSPF, IS-IS, and RIP. IGP protocols allow routers within a single network to communicate with each other and share information about the network topology. Inter-domain routing, also known as Exterior Gateway Protocol (EGP), is used to exchange routing information between different autonomous systems (ASes) or networks. Examples of EGP protocols include Border Gateway Protocol (BGP) and Exterior Gateway Protocol (EGP). EGP protocols allow routers in different networks to communicate with each other and exchange information about how to reach different networks. In summary, the key difference between intra-domain routing and inter-domain routing is the scope of the network over which routing information is exchanged. Intra-domain routing is used within a single network, while inter-domain routing is used between different networks.

Which routing protocol is used for intra-domain routing in the Internet?

C. Open Shortest Path First (OSPF) Popular Protocols of this routing are RIP(resource information protocol) and OSPF(open shortest path first).

Which type of routing protocol uses the Bellman-Ford algorithm to calculate the best path for forwarding IP packets?

B. Distance-vector routing protocol

Consider a network with three routers, A, B, and C. The routing table for router A has the following entries: Destination: 192.168.1.0/24, Next Hop: B Destination: 192.168.1.128/28, Next Hop : D Destination: 192.168.2.0/24, Next Hop: C If router A receives an IP packet with a destination address of 192.168.1.10, what will be the next hop for this packet?

For the following network, what will be the routing table for c, if we use link-state routing .

nptel computer networks assignment answers

Which of the following datastructures are used for speeding up the Longest Prefix Matching based Forwarding algorithms in routers?

d. Patricia Trees

Suppose we have n number of routes in a routing table. A Packet bearing a certain IP arrives at the router and requires it to be routed to the appropriate next hop location. Assuming that the router maintains a Patricia Tree for the routing table and we are using IPV4 addresses, what is the time complexity of this forwarding?

Bgp communication packet types are.

b. OPEN, UPDATE, NOTIFICATION, KEEPALIVE OPENN: This message type establishes a BGP session between two peer nodes. UPDATE: This message type transfers routing information between GP peers. NOTIFICATION: This message is sent when an error condition is detected. KEEPALIVE: This message determines if peers are reachable.

  • Only binary trie has the best lookup and update complexity
  • Only path compressed trie has the best lookup and update complexity
  • Both binary and path-compressed tries have the same lookup and update complexity
  • Binary trie and path-compressed tries have the same lookup complexity but different update complexity.

2 .  Given a routing table having 5 prefixes with prefix length of 0, 2, 4, 6, 8 respectively, ……… pointer references are required in the worst case for the binary trie

3. In which case will a path-compressed trie resemble a regular binary trie?

  • When trie is sparse
  • When trie is dense
  • When trie is almost complete
  • When trie is full

w2q4

6. Consider the prefix table shown below; which of the following prefixes should be merged to reduce the size of the table for storage in TCAM?

w2q6

7. Consider the prefix database table shown below; what is the route lookup sequence to reach the destination address 10100000 in 1-bit binary trie?

w2q7

  • Right, Left, Left, Right
  • Right, Left, Right, Right
  • Right, Left, Right, Left
  • Left, Right, Left, Right

8. Which of the following statements about the DIR-24-8-BASIC hardware-based routing lookup algorithm is/are correct?

  • If the length of the prefix P is less than 25 bits, the first bit of the entry is set to one in TBL24.
  • If the length of the prefix P is less than 24 bits, the first bit of the entry is set to zero in TBL24.
  • If the length of the prefix P is greater than 24 bits, the first bit of the entry is set to one in TBL24.
  • If the length of the prefix P is greater than 24 bits, the first bit of the entry is set to zero in TBL24.

9. Consider the following scenarios for how the DIR-24-8 algorithm performs route lookups using two tables. Assume the routes listed below are already in the table: 10.54/16 (1), 10.54.34/24 (2), and 10.54.34.192/26 (3). The first route requires entries in TBL24 (First Table), while the second and third routes require entries in TBLlong (Second Table). Which of the following statements is/are correct based on the above scenario?

  • If a packet arrives with the destination address 10.54.22.147, the table will return an entry with the correct next hop (1)
  • If a packet arrives with the destination address 10.54.34.23, the table will return an entry with the correct next hop (2)
  • If a packet arrives with the destination address 10.54.34.15, the table will return an entry with the correct next hop (1)
  • If a packet arrives with the destination address 10.54.39.128, the table will return an entry with the correct next hop (1)

10. Which of the statements below is/are correct?

  • Path-compressed trie is an efficient way to compress a trie when nodes are sparsely populated.
  • Level compression trie is an efficient way to compress a trie when nodes are densely populated.
  • Path-compressed trie is an efficient way to compress a trie when nodes are densely populated.
  • Multi-bit trie can improve route lookup performance.
