It points out the advantages of Cloud over traditional hosting infrastructures and how you can implement them to keep your applications up and running all the time. The SA Associate exam will include questions that will test your knowledge on the best practices through different example scenarios.
- Using Amazon Web Services for Disaster Recovery: This paper explains the different types of disaster recovery plans that you can perform in AWS. It is your responsibility as a Solutions Architect to mitigate any potential downtime when disaster strikes. Depending on your RPO and RTO, a proper disaster recovery plan will be a deciding factor between business continuity and revenue loss.
- AWS Security Practices: This paper supplements your study on the AWS services and features such as IAM, Security Groups, nACLs, etc. You should read this paper since security specific questions occasionally pop up in the exam.
- AWS Storage Services Overview: This paper supplements your study on the different AWS Storage options such as S3, EBS, EFS, Glacier, etc. It contains a good detail of information and comparison for each storage service, which is crucial in knowing the best service to use for a situation.
- Building Fault-Tolerant Applications on AWS: This paper discusses the many ways you can ensure your applications are fault-tolerant in AWS. It also contains multiple scenarios where the practices are applied and which AWS services were crucial for the scenario.
- EC2 – As the most fundamental compute service offered by AWS, you should know about EC2 inside out.
- Lambda – Lambda is the common service used for serverless applications. Study how it is integrated with other AWS services to build a full stack serverless app.
- Elastic Load Balancer – Load balancing is very important for a highly available system. Study about the different types of ELBs, and the features each of them supports.
- Auto Scaling – Study what services in AWS can be auto scaled, what triggers scaling, and how auto scaling increases/decreases the number of instances.
- Elastic Block Store – As the primary storage solution of EC2, study on the types of EBS volumes available. Also study how to secure, backup and restore EBS volumes.
- S3 / Glacier – AWS offers many types of S3 storage depending on your needs. Study what these types are and what differs between them. Also review on the capabilities of S3 such as hosting a static website, securing access to objects using policies, lifecycle policies, etc. Learn as much about S3 as you can.
- Storage Gateway – There are occasional questions about Storage Gateway in the exam. You should understand when and which type of Storage Gateway should be used compared to using services like S3 or EBS. You should also know the use cases and differences between DataSync and Storage Gateway.
- EFS – EFS is a service highly associated with EC2, much like EBS. Understand when to use EFS, compared to using S3, EBS or instance store. Exam questions involving EFS usually ask the trade off between cost and efficiency of the service compared to other storage services.
- RDS / Aurora – Know how each RDS database differs from one another, and how they are different from Aurora. Determine what makes Aurora unique, and when it should be preferred from other databases (in terms of function, speed, cost, etc). Learn about parameter groups, option groups, and subnet groups.
- DynamoDB – The exam includes lots of DynamoDB questions, so read as much about this service as you can. Consider how DynamoDB compares to RDS, Elasticache and Redshift. This service is also commonly used for serverless applications along with Lambda.
- Elasticache – Familiarize yourself with Elasticache redis and its functions. Determine the areas/services where you can place a caching mechanism to improve data throughput, such as managing session state of an ELB, optimizing RDS instances, etc.
- VPC/NACL/Security Groups – Study every service that is used to create a VPC (subnets, route tables, internet gateways, nat gateways, VPN gateways, etc). Also, review on the differences of network access control lists and security groups, and during which situations they are applied.
- Route 53 – Study the different types of records in Route 53. Study also the different routing policies. Know what hosted zones and domains are.
- IAM – Services such as IAM Users, Groups, Policies and Roles are the most important to learn. Study how IAM integrates with other services and how it secures your application through different policies. Also read on the best practices when using IAM.
- CloudWatch – Study how monitoring is done in AWS and what types of metrics are sent to CloudWatch. Also read upon Cloudwatch Logs, CloudWatch Alarms, and the custom metrics made available with CloudWatch Agent.
- CloudTrail – Familiarize yourself with how CloudTrail works, and what kinds of logs it stores as compared to CloudWatch Logs.
- Kinesis – Read about Kinesis sharding and Kinesis Data Streams. Have a high level understanding of how each type of Kinesis Stream works.
- CloudFront – Study how CloudFront helps speed up websites. Know what content sources CloudFront can serve from. Also check the kinds of certificates CloudFront accepts.
- SQS – Gather info on why SQS is helpful in decoupling systems. Study how messages in the queues are being managed (standard queues, FIFO queues, dead letter queues). Know the differences between SQS, SNS, SES, and Amazon MQ.
- SNS – Study the function of SNS and what services can be integrated with it. Also be familiar with the supported recipients of SNS notifications.

The AWS Solutions Architect Associate (SAA-C02) exam loves to end questions that ask for highly available or cost-effective solutions. Be sure to understand the choices provided to you, and verify that they have correct details. Some choices are very misleading such that it seems it is the most appropriate answer to the question, but contains an incorrect detail of some service.
When unsure of which options are correct in a multi-select question, try to eliminate some of the choices that you believe are false. This will help narrow down the feasible answers to that question. The same goes for multiple choice type questions. Be extra careful as well when selecting the number of answers you submit. Check out the tips mentioned in this article for more information.
As mentioned in this review, you should be able to differentiate services that belong in one category with one another. Common comparisons include:
- EC2 vs ECS vs Lambda
- S3 vs EBS vs EFS
- CloudFormation vs OpsWorks vs Elastic Beanstalk
- SQS vs SNS vs SES vs MQ
- Security Group vs nACLs
- The different S3 storage types vs Glacier
- RDS vs DynamoDB vs Elasticache
- RDS engines vs Aurora
The Tutorials Dojo Comparison of AWS Services contains excellent cheat sheets comparing these seemingly similar services which are crucial to solving the tricky scenario-based questions in the actual exam. By knowing each service’s capabilities and use cases, you can consider these types of questions already half-solved.
Lastly, be on the lookout for “key terms” that will help you realize the answer faster. Words such as millisecond latency, serverless, managed, highly available, most cost-effective, fault-tolerant, mobile, streaming, object storage, archival, polling, push notifications, etc are commonly seen in the exam. Time management is very important when taking AWS certification exams, so be sure to monitor the time you consume for each question.
