Refer to the exhibit. A network administrator has configured a network after subnetting the network number 192.168.0.0/28. Workstation 1 is not able to communicate with Workstation 2. What is the cause of this loss in communications?

Workstation 1 and Workstation 2 are on the same subnet.

The serial connections are using addresses from the LAN subnets.

Workstation 1 is not on the same network that the Router 1 LAN interface is on.

If routers are used in the network, IP addresses do not need to be subnetted.

bus

star

ring

mesh

14. Why do vendors utilize the OSI model when designing networking products?

It places requirements on all vendors that develop proprietary networking technologies for advance networking systems.

It ensures greater compatibility and interoperability with equipment from different vendors.

The International Organization for Standards develops all new products to be incorporated into the product.

It is mandated by the International Organization for Standardization that network products be compliant with the OSI model.

 

15. An Ethernet host receives a frame, calculates the FCS, and compares the calculated FCS to the FCS received in the frame. The host finds that the two FCS values do not match. What action will be taken by the host?

The host discards the frame.

The host processes the data frame normally.

The host initiates a request for retransmission of the frame.

The host sends the frame content to an upper layer protocol for error recovery.

 

16. Why would a company install a switch instead of a hub when building or expanding a corporate network?

A switch manages frames faster than a hub does.

A switch operates at 100 Mbps. A hub operates at a maximum of 10 Mbps.

A switch modifies the Ethernet frame to remove any errors. A hub forwards the frame exactly as it arrived.

A switch provides more bandwidth by sending frames only out the port to which the destination device is attached. A hub sends the frame out all ports except the source port.

A device sends data without checking media availability because all devices have equal access.

Multiple devices can successfully transmit simultaneously.

Only one device can successfully transmit at a time.
