CCNA OSI and TCP/IP Models Quiz

What is the primary purpose of a networking model?

• To increase the speed of network connections

• To serve as a marketing tool for network equipment

• To provide a physical connection between devices

• To categorize and structure networking protocols and standards

Which layer of the OSI model is responsible for data format translation?

• Application Layer

• Transport Layer

• Presentation Layer

• Session Layer

What is the primary function of the session layer in the OSI model?

• Translating network addresses

• Encrypting data transmissions

• Managing sessions between hosts

• Physical transmission of data

What does the transport layer of the OSI model provide?

• Segmentation and host-to-host communication

• Encryption and data format translation

• Physical connectivity between devices

• Session management between applications

Which OSI layer is directly involved when a router forwards data packets based on IP addresses?

• Application Layer

• Transport Layer

• Network Layer

• Data Link Layer

Which layer of the OSI model handles logical addressing and path selection?

• Transport Layer

• Data Link Layer

• Network Layer

• Session Layer

Which OSI model layer adds headers and trailers to data packets?

• Application Layer

• Physical Layer

• Data Link Layer

• Network Layer

How does the TCP/IP model differ from the OSI model in terms of layer structure?

• TCP/IP excludes the physical and data link layers

• TCP/IP combines several OSI layers into fewer layers

• TCP/IP has more layers than OSI

• TCP/IP is a subset of the OSI model without modifications

In the TCP/IP model, what is the equivalent of the OSI model's data link and physical layers?

• Transport Layer

• Application Layer

• Internet Layer

• Link Layer

What is encapsulation in the context of network models?

• The process of adding headers and trailers to data

• A method of encrypting data for secure transmission

• The physical connection setup between networking devices

• A type of network topology
