各位好：
我最近想考ccna证照，在做第一部分的期末考题，
做到一题看答案怎么想都想不透，
想请教一下有没有哪位版友大大能够回答。
我的疑惑就是说为什么server设定是subnet mask错误，
题目不是已经限定internal address是在/27，
所以subnet mask设成255.255.255.224很合理啊?!
server连不上internet有可能是因为跟gateway连线有问题，
一看gateway发现是192.168.5.1不是在192.168.5.96/27的网段内，
那不是代表是default gateway设错了吗?
为什么答案是subnet mask设错呢?
==================================以下是题目=======================
Refer to the exhibit. The network administrator for a small advertising
company has chosen to use the 192.168.5.96/27 network for
internal LAN addressing.
As shown in the exhibit, a static IP address is assigned
to the company web server. However, the web server cannot access the Internet.
The administrator verifies that local workstations with IP addresses that
are assigned by a DHCP server can access the Internet, and the
web server is able to ping local workstations.
Which component is incorrectly configured?
( ) default gateway address
( ) host ip address
( ) dns address
(o) subnet mask
******************星号中间是图****************************
ip address: 192.168.5.98
subnet mask: 255.255.255.224
Default gateway: 192.168.5.1
dns server: 128.208.3.254
***********************************************************

看起来是default gateway有问题

网络考题常有答案是错的，毕竟答案都不是官方解答把题目一两个关键句贴上google就可以找到不同答案

Subnet 有问题啊，重点在倒数第二句。

从题目跟附图的资讯，只能说明显的问题是gateway错误倒数第二句说明了server跟其他DHCP电脑是通的，subnet就应该是对的，除非有给DHCPserver设定才能进一步验证有趣的是网络上搜到的答案，甚至连DNS错误都有人提供原PO若是觉得不放心，自己用packet tracerLAB一下应该心里就有底了

谢谢各位大大的回答
