需要提醒考取认证的同学,一些分享和资料可能比较旧了,AWS认证的特点就是经常 更改考试指南,这点特别无语啊。英文版考试2019/2/4开始采用新的考试指南了,千万别按以前的考试指南复习啊!!!!!
中文版考试是2019年4月8日开始。
AWS认证 Solutions Architect- 专业级最新版本在2018年12月3日完成了Beta版本测试,并将在2019年4月8日发布韩语和简体中文版。目前提供韩文和简体中文版本的本门认证考试的最终日期为2019年4月7日。如果您有计划在2019年4月8日后参加此认证考试,请使用本考试指南做准备。

如何准备考试
可能每个人的基础不同,使用AWS水平也不同,我是从最基本的书【AWS Certified Solutions Architect Official Study Guide】开始看的,
因为比较系统,虽然可能跟现在的AWS服务有点旧了,但是最基础的服务还是
EC2,S3,VPC,最基本的东西,看书能比较系统一些,白皮书太多了,全部看完可能花费时间太长。

AWS考试的特点,个人考试时感觉到60%-70%都是情景题,直接考知识点的占比比较小一些,这些情景题需要融合好几个知识点和AWS服务,挑选一个最优的,有的题,其他选项也是可以实现的,但是不是性价比最优的。

除了看书,必须看考试指南列出来的几个白皮书以及FAQs。

模拟考试是否有必要参加?模拟考试是40美金。正式考试300美金,个人感觉还是有必要参加的,模拟考试可以看看个人准备的是否充分,模拟考试得分会按照每个知识域进行评分,可以有重点的学习不充分的知识点。
我模拟考试是80%,但是不提供正确的答案,这点有点不是很人性。

样题库里的情景题跟考试的情景题类型差不多。大概就是这模样。

Your company’s on-premises content management system has the following architecture:
 Application Tier – Java code on a JBoss application server
 Database Tier – Oracle database regularly backed up to Amazon Simple Storage Service (S3) using
the Oracle RMAN backup utility
 Static Content – stored on a 512GB gateway stored Storage Gateway volume attached to the
application server via the iSCSI interface
Which AWS based disaster recovery strategy will give you the best RTO?
A) Deploy the Oracle database and the JBoss app server on EC2. Restore the RMAN Oracle backups from
Amazon S3. Generate an EBS volume of static content from the Storage Gateway and attach it to the
JBoss EC2 server.
B) Deploy the Oracle database on RDS. Deploy the JBoss app server on EC2. Restore the RMAN Oracle
backups from Amazon Glacier. Generate an EBS volume of static content from the Storage Gateway and
attach it to the JBoss EC2 server.
C) Deploy the Oracle database and the JBoss app server on EC2. Restore the RMAN Oracle backups from
Amazon S3. Restore the static content by attaching an AWS Storage Gateway running on Amazon EC2
as an iSCSI volume to the JBoss EC2 server.
D) Deploy the Oracle database and the JBoss app server on EC2. Restore the RMAN Oracle backups from
Amazon S3. Restore the static content from an AWS Storage Gateway-VTL running on Amazon EC2

突然发现我考试的有一道题,来自样题。
An ERP application is deployed in multiple Availability Zones in a single region. In the event of failure, the
RTO must be less than 3 hours, and the RPO is 15 minutes. The customer realizes that data corruption
occurred roughly 1.5 hours ago. Which DR strategy can be used to achieve this RTO and RPO in the
event of this kind of failure?
A) Take 15-minute DB backups stored in Amazon Glacier, with transaction logs stored in Amazon S3 every
5 minutes.
B) Use synchronous database master-slave replication between two Availability Zones.
C) Take hourly DB backups to Amazon S3, with transaction logs stored in S3 every 5 minutes.
D) Take hourly DB backups to an Amazon EC2 instance store volume, with transaction logs stored in
Amazon S3 every 5 minutes.

可以手动做一些实验,都是最基础的AWS服务,不过貌似免费的越来越少了,基本上大多数都得花钱了,美金不算少。可以自己注册一个AWS免费账号,自己练习,记得免费套餐说明,多看看,本人没仔细看,刚开始两天花了20多美金,主要是做了ELB练习,忘记删除服务了。如果不能确定花不花钱,建议每次做完实验都是删除掉。

最后说明:AWS认证确实不太好考,不能太轻视,出的考试题,确实很有水平。不是简单的考知识点,需要深刻了解AWS各种服务。但也无需太过于担心,只要努力准备,还是能通过的。参加认证的过程,其实就是最好的学习过程。祝各位参加认证的同学都能通过,加油!!!
