Network+ (N10-008) with complete solution

Network+ (N10-008) with complete solution 1. OSI Model Layers: Application Presentation Session Transport Network Data Link Physical 2. Will OSI Model Layers communicate with different layers: No, only talk to the same layer on the other device. 3. Can OSI Layer 2 communicate will layer 5: No, OSI Layers can only commu- nicate with layers one above or below. 4. What is the Purpose of the OSI Model: Provide a model to describe how data moves from source device to destination device. 5. What are the responsibilities of Layer 1 of the OSI Model: Transmission of bits over medium. 6. What is the Physical medium that Layer 1 of the OSI model use to transmit data.: Cables, Connectors, NIC, Repeaters, and Hubs 7. What is the Responsibilities of the Data Link Layer.: For Node to Node delivery & creates frames & Physical Address ( MAC Address). 8. What does the Data Link Layer responsible to control: Access, Flow, and Error 9. Describe Transmission Control's function: Establishing & Terminating, Media Access Management, Flow Control, Error Control, Access Control. 10. What does the logical link control (LLC) sublayer of the data link layer determines?: To use either the connectionless or connection - oriented. 11. What are the basic functions of the Network Layer: Packet Addressing, Address Conversion, Source-to-Destination Delivery, & Routing. 12. Does a router determine the best path to destination?: Yes 13. Does the Router provide physical or logical connections for the network- : It Provides Logical Address scheme 14. Packetizing at the network layer involves: Creates packet from transport layer, encapsulation, and applied IP address both source and destination. 15. Fragmentation at the network layer does: Divides large packets into smaller ones so
