問一個子網路遮罩的問題
 

You are the network administrator for TestKing.com. The network consists of a
single Active Directory domain named testking.com and a single subnet. All servers
run Windows Server 2003. The network contains 150 client computers and 16
servers. Al computers on the network use the 10.10.0.0/16 address scheme.
Dr King, your manager, instructs you to place the 16 servers into a separate subnet
that uses the 192.168.10 public addressing scheme. You must plan for a maximum of
30 servers in the future.
You need to configure a new subnet mask. The subnet mask must allow a sufficient
number of IP addresses for the existing servers and future growth. However, you
want to conserve addresses as much as possible.
Which subnet mask should you use?

答案是不是255.255.255.248?

為什麼正確解答是255.255.255.224
答案錯了嗎

CCNA考古題?
TK的答案有滿多錯的吧

因為.....他計畫有30台呀

255.255.255.248 的子網路遮罩根本不符合

至少要255.255.255.224 才符合

喔喔
我知道了
我以為他要有30個網段

我看到時候差點沒嚇到...

怪~怎麼又看到這樣的題目了 :jolin: :laugh:

You must plan for a maximum of
30 servers in the future.

這一句話是關鍵

128+64+32=224

11100000=224
不過意思跟樓上的大大是一樣的

/27，看來我也可以考了噢~~~
