IP Chapter 2 and 3 MCQs

Differences between IPv4 and IPv6 Addressing

• IPv4 uses a 32-bit address, allowing for approximately 4.3 billion unique addresses, while IPv6 utilizes a 128-bit address, enabling an immense pool of 340 undecillion addresses.
• IPv4 is represented in decimal format (e.g., 192.168.1.1), whereas IPv6 addresses are represented in hexadecimal format (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
• IPv4 supports broadcast as a method for data transmission; IPv6 eliminates broadcast, adopting multicast and anycast methods instead for more efficient packet routing.
• IPv6 offers built-in security features like IPsec, which are optional in IPv4, enhancing overall network security.
• Address autoconfiguration in IPv6 simplifies network setup by enabling devices to automatically generate their own addresses, a feature lacking in IPv4.

Role of Address Resolution Protocol (ARP)

• ARP translates IP addresses into MAC addresses, allowing devices to communicate on a local area network (LAN).
• It operates at the link layer of the OSI model, providing the necessary information for packet delivery within a local network segment.
• ARP maintains a cache of mappings between IP addresses and MAC addresses to reduce the need for repetitive query broadcasts, resulting in efficient network operation.

Importance of Subnetting in Network Efficiency

• Subnetting divides a large network into smaller, more manageable subnetworks, reducing traffic congestion by limiting broadcast domains.
• It optimizes IP address allocation by allowing organizations to assign ranges of addresses based on specific departmental or functional needs.
• Subnetting enhances security by isolating segments of the network, maintaining controlled access to sensitive data and systems.
• It improves network performance by reducing the size of broadcast transmissions, thereby facilitating quicker data transmission.

Function of a Router in Data Transmission

• Routers connect multiple networks, directing data packets between them based on their destination IP addresses.
• They operate at the network layer of the OSI model, determining the best path for data transmission to optimize speed and reliability.
• Routers utilize routing tables and protocols (e.g., OSPF, BGP) to update their knowledge of network topology and maintain efficient routing paths.
• They can provide additional functionalities such as network address translation (NAT) and firewall capabilities, enhancing security.

Significance of the Three-Way Handshake in TCP Connections

• The three-way handshake establishes a reliable connection between a client and server before data transmission, ensuring that both parties are ready to communicate.
• The process involves three steps:
  • SYN: The client sends a synchronization request to the server.
  • SYN-ACK: The server acknowledges receipt of the request and sends its own synchronization acknowledgment back to the client.
  • ACK: The client sends an acknowledgment back to the server, completing the connection setup.
• This mechanism helps guarantee that both parties are synchronized and prepared for data exchange, increasing connection reliability.
