Level 3 - ISO Quiz

What is the purpose of the OSI model in networking?

• a) To divide networking tasks into logical layers for easier comprehension.
• b) To establish an international standard for currency conversion.
• c) To create a new coding language for web development.
• d) To define the structure of a computer's central processing unit (CPU).

What is a limitation of the OSI model?

• a) It can't support multiple languages.
• b) Industry implementations rarely have a layer-to-layer correspondence with the OSI layers.
• c) It's too difficult for network professionals to understand.
• d) It doesn't allow for modularity in networking features.

At which layer in the OSI model would you find the Session ID?

• a) Application Layer
• b) Presentation Layer
• c) Session Layer
• d) Transport Layer

How does a frame different from a packet in the OSI model?

• 2. Frames contain both the network and data link layer addresses, facilitating local network communication, while packets only carry the network layer address for broader routing.

• 1. Frames are used for error detection and correction at the data link layer (Layer 2), while packets focus on routing and logical addressing at the network layer (Layer 3).

• 1. A frame corresponds to the data link layer (Layer 2) and is responsible for local network communication, while a packet belongs to the network layer (Layer 3) and is involved in end-to-end communication across multiple networks.

• 1. A frame operates at the data link layer (Layer 2) of the OSI model, whereas a packet operates at the network layer (Layer 3).

What is the difference between connectionless and connection-oriented services in the OSI model?

• a) Connectionless services deliver data without establishing a connection, while connection-oriented services establish a connection before transferring data.
• b) Connectionless services can only transfer data within the same network, while connection-oriented services can transfer data between different networks.
• c) Connectionless services cannot handle large data transfers, while connection-oriented services can.
• d) Connectionless services require a physical cable connection, while connection-oriented services do not.

What is the name of Layer 3 in the OSI model?

• a) Network Layer
• b) Transport Layer
• c) Session Layer
• d) Data Link Layer

What is the name of Layer 5 in the OSI model?

• a) Network Layer
• b) Transport Layer
• c) Session Layer
• d) Presentation Layer

Which OSI model layers typically correspond to the network architecture?

• a) Layers 1-4
• b) Layers 2-5
• c) Layers 3-6
• d) Layers 4-7

How does the OSI model promote interoperability between networks and devices?

• a) By mandating the use of a single protocol.
• b) By providing a common language and reference point for network professionals.
• c) By requiring all devices to use the same operating system.
• d) By enforcing a strict hierarchical structure in all networks.

Why is using a theoretical model like the OSI model advantageous for understanding networking?

• a) It provides a clear blueprint for manufacturing networking hardware.
• b) It simplifies network troubleshooting by highlighting problem areas.
• c) It allows for the dynamic assignment of IP addresses.
• d) It makes it easier to learn programming languages.
