Exam 7: Network Reference Models and Standards

One job that a router performs is that of gatekeeper, which means that it can be configured to only allow certain packets access into the network based on a list of rules. What is that process called?

Name the PDU at each layer of the OSI model.

Match each item with a statement below. a.Application layer b.Presentation layer c.Session layer d.Transport layer e.Network layer f.Data Link layer g.Physical layer h.Media Access Control sublayer i.Logical Link Control sublayer j.OSI reference model -Computers operate at this layer.

What information would you find in the header of a Transport layer PDU?

Which layer is responsible for the encoding of signals?

What is the IEEE standard that governs all forms of Ethernet media and interfaces?

Match each item with a statement below. a.Application layer b.Presentation layer c.Session layer d.Transport layer e.Network layer f.Data Link layer g.Physical layer h.Media Access Control sublayer i.Logical Link Control sublayer j.OSI reference model -Routers operate at this layer.

Match each item with a statement below. a.Application layer b.Presentation layer c.Session layer d.Transport layer e.Network layer f.Data Link layer g.Physical layer h.Media Access Control sublayer i.Logical Link Control sublayer j.OSI reference model -This is the general framework for how networking systems should operate.

In regards to the OSI Reference Model, what is peer communication?

Match each item with a statement below. a.Application layer b.Presentation layer c.Session layer d.Transport layer e.Network layer f.Data Link layer g.Physical layer h.Media Access Control sublayer i.Logical Link Control sublayer j.OSI reference model -This sublayer manages access to the physical medium.

Which layer of the OSI model is responsible for protocol conversion, if necessary?

Match each item with a statement below. a.Application layer b.Presentation layer c.Session layer d.Transport layer e.Network layer f.Data Link layer g.Physical layer h.Media Access Control sublayer i.Logical Link Control sublayer j.OSI reference model -This layer handles communication setup and teardown.

What are the benefits to using a layered approach?

Match each item with a statement below. a.Application layer b.Presentation layer c.Session layer d.Transport layer e.Network layer f.Data Link layer g.Physical layer h.Media Access Control sublayer i.Logical Link Control sublayer j.OSI reference model -This layer handles data formatting and translation.

What is encoding, and where does it take place?

The ____________ layer of the TCP/IP model combines the top three layers of the OSI model into one layer.

One of the problems that can occur in the Network layer is the incorrect configuration of a host's IP address.

What layer is responsible for making sure that the data that it sends and receives is in a format that the receiving and sending computers can understand?

The Transport layer is the same in both the OSI model and the TCP/IP model.

What does the Data Link layer do with a frame after it receives it?
