近几周CHATGPT非常火，我们也不能免俗试试用CHATGPT来解答一下SAA问题，看看CHATGPT的思路准确不准确。
本次选择SAA的官方样题，链接如下
我们在此抽样一道题来做一下解答。
An application running on AWS uses an Amazon Aurora Multi-AZ DB cluster deployment for its database. When evaluating performance metrics, a solutions architect discovered that the database reads are causing high I/O and adding latency to the write requests against the database. What should the solutions architect do to separate the read requests from the write requests?
A) Enable read-through caching on the Aurora database.
B) Update the application to read from the Multi-AZ standby instance.
C) Create an Aurora replica and modify the application to use the appropriate endpoints.
D) Create a second Aurora database and link it to the primary database as a read replica.
先把题目直接抛给CHATGPT，得到以下内容
除了Global Database有点发散以外，其实它已经提出了Replica的方案，并且进一步提到可以使用Redis来offload request，当然现在Serverless当道，最后还提了一下Aurora Serverless（勉强算是一种提供任意规模性能方案
这时我们把选项给他，看他如何判断
Hmm，有点一言难尽，我们看看它对C是如何解释的
Option C) Create an Aurora replica and modify the application to use the appropriate endpoints is not correct because an Aurora replica refers to a read replica, not a separate DB cluster. To separate read requests from write requests, you need to create a separate Aurora DB cluster and link it to the primary cluster as a read replica.
其实这也可以看到CHATGPT的问题，虽然它的逻辑可能是自洽的，文字也很多，但是事实上它是不清楚的，我也看到很多朋友直接拿它来生成IAM Policy了，内容也是不完整。
总结一下，CHATGPT可以用来解决一些通用的问题（然而这些问题也是最不需要它来解决的问题），可能用来写文章比较合适。
