The characteristic of AWS certification is that the exam guide is often changed, which is particularly speechless. Don’t follow the previous exam guide!

How to prepare for the exam:

Maybe everyone has different foundations and different levels of using AWS. I started reading from the most basic book [AWS Certified Solutions Architect Official Study Guide because it is more systematic.

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

Suddenly found that I had a question in the exam, which came from a sample question. 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.
