(ii) Close investment holding company status
Carver Ltd will not become a close investment-holding company if it purchases the office building as, although it will no
longer be a trading company, it intends to rent out the building to a number of tenants none of whom is connected to
the company.
Carver Ltd will become a close investment holding company if it purchases a portfolio of quoted shares as it will no
longer be a trading company. As a result it will pay corporation tax at the full rate of 30% regardless of the level of its
profits.

第8题：

The Ezonexam corporate LAN consists of one large flat network. You decide to segment this LAN into two separate networks with a router. What will be the affect of this change?

A．The number of broadcast domains will be decreased.

B．It will make the broadcasting of traffic between domains more efficient between segments.

C．It will increase the number of collisions.

D．It will prevent segment 1's broadcasts from getting to segment 2.

E．It will connect segment 1's broadcasts to segment 2.

正确答案：D
解析：Explanation
A router does not forward broadcast traffic. It therefore breaks up a broadcast domain, reducing unnecessary network traffic. Broadcasts from one segment will not be seen on the other segment.

Incorrect Answers:
A. This will actually increase the number of broadcast domains from one to two.

B. All link level traffic from segment one to segment two will now need to be routed between the two interfaces of the router. Although this will reduce the traffic on the LAN links, it does also provide a less efficient transport between the segments.

C. Since the network size is effectively cut into half, the number of collisions should decrease dramatically.

E. Broadcasts from one segment will be completely hidden from the other segment.
