OSI and TCP/IP Models - Case Studies

Q. In the context of IP addressing, what does CIDR stand for?

Solution

CIDR stands for Classless Inter-Domain Routing, which allows for more efficient allocation of IP addresses.

Correct Answer: A — Classless Inter-Domain Routing

Q. In the OSI model, which layer is responsible for error detection and correction?

Solution

The Data Link Layer (Layer 2) is responsible for error detection and correction to ensure reliable data transfer.

Correct Answer: B — Data Link Layer

Q. What is the maximum length of a standard Ethernet frame?

Solution

The maximum length of a standard Ethernet frame is 1518 bytes, which includes the header and trailer.

Correct Answer: B — 1518 bytes

Q. What is the primary function of the Network Layer in the OSI model?

Solution

The primary function of the Network Layer (Layer 3) is to route packets across different networks.

Correct Answer: B — Routing packets

Q. What is the primary purpose of the Link Layer in the TCP/IP model?

Solution

The primary purpose of the Link Layer in the TCP/IP model is to provide physical addressing and manage the physical connection.

Correct Answer: B — Physical addressing

Q. Which addressing scheme is used in the Network Layer of the OSI model?

Solution

IP Addressing is used in the Network Layer (Layer 3) of the OSI model to identify devices on a network.

Correct Answer: B — IP Addressing

Q. Which layer of the TCP/IP model corresponds to the OSI model's Network Layer?

Solution

The Internet Layer of the TCP/IP model corresponds to the Network Layer of the OSI model, handling routing and addressing.

Correct Answer: C — Internet Layer

Q. Which OSI layer is responsible for establishing, managing, and terminating sessions?

Solution

The Session Layer (Layer 5) is responsible for establishing, managing, and terminating sessions between applications.

Correct Answer: B — Session Layer
