Quiz-OSI Layers

Which layer of the OSI model is responsible for user interface and interaction with applications like email and online games?

• Application Layer

• Data Link Layer

• Transport Layer

• Network Layer

Which layer of the OSI model translates commands from the application layer into universal networking formats and handles data encryption?

• Physical Layer

• Session Layer

• Presentation Layer

• Transport Layer

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

• Seeking the best-known path to route information to its destination

• Defining how data is sent and providing validation and firewall security

• Ensuring a transmission occurs without errors and providing a physical MAC address

• Establishing and managing a session between end-user application processes

Which layer of the OSI model provides flow control, error detection, and correction, and uses protocols like TCP and UDP?

• Physical Layer

• Data Link Layer

• Network Layer

• Transport Layer

In the OSI model, which layer determines the best way to route information to its destination, similar to using a GPS?

• Network Layer

• Data Link Layer

• Session Layer

• Presentation Layer

What are the two sub-layers of the Data Link Layer in the OSI model?

• Logical Link Control (LLC) and Media Access Control (MAC)

• Ethernet and Token Ring

• Flow Control and Error Detection

• Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)

Which layer of the OSI model consists of the physical components in a Local Area Network (LAN) such as networking hardware and Ethernet cables?

• Presentation Layer

• Application Layer

• Session Layer

• Physical Layer

What is the main function of the physical layer in the OSI model?

• Handling physical components in a network and dealing with cabling issues

• Establishing and managing a session between end-user application processes

• Translating commands from the application layer into universal networking formats

• Defining how data is sent and providing validation and firewall security

Which protocol is associated with the application layer of the OSI model for sending and receiving data through email and online games?

• Ethernet

• Transmission Control Protocol (TCP)

• Hypertext Transfer Protocol (HTTP)

• Simple Mail Transfer Protocol (SMTP)

What is the main function of the transport layer in the OSI model?

• Defining how data is sent and providing validation and firewall security

• Seeking the best-known path to route information to its destination

• Ensuring a transmission occurs without errors and providing a physical MAC address

• Provides flow control, error detection, and correction
