TCP/IP Structure and Addressing

The address 68.56.189.17 belongs to which Internet protocol (IP) class?

Class A.

The Network Layer must do what to a received frame first, in order to determine the route over which it will forward the datagram to the next network?

Decapsulate the packet.

All computers running on the transmission control protocol/Internet protocol (TCP/IP) suite have which of the following in common?

Each computer is assigned its own Internet protocol (IP) address.

The Open Systems Interconnection reference model (OSI/RM) Network Layer serves which primary purpose?

It uses Layer 3 addresses to create multiple routed networks.

Which device evaluates and acts upon a packet's Internet protocol (IP) address?

Router.

The physical address of a device is processed by which layer of the Open Systems Interconnection reference model (OSI/RM)?

The Data Link Layer.

A repeater operates at which layer of the Open Systems Interconnection reference model (OSI/RM)?

The Physical Layer.

Which layer of the Open Systems Interconnection reference model (OSI/RM) would you suspect as being the problem when packets are arriving at the server but no information is being returned to the client?

The Transport Layer.

What happens to a datagram sent by a higher level protocol to a 127.x.y.z address?

The datagram loops back inside the host and never leaves the network interface card (NIC).

What network information can be determined from a logical Internet protocol (IP) address?

The host portion and network portion.
