AWS Certified Solutions Architect Professional Exam Study Path
Few years ago, before you can take the AWS Certified Solutions Architect Professional (or SA Pro for short) exam, you would first have to pass the associate level exam of this track. This is to ensure that you have sufficient knowledge and understanding on architecting in AWS, before tackling the more difficult certification. In October 2018, AWS removed this ruling so that there are no more prerequisites for taking the Professional level exams. You now have the freedom to directly pursue this certification if you wish to.
This certification is truly a levelled-up version of the AWS Solutions Architect Associate certification. It examines your capability to create well-architected solutions in AWS, but on a grander scale and with more difficult requirements. Because of this, we recommend that you go through our exam preparation guide for the AWS Certified Solutions Architect Associate and even the AWS Certified Cloud Practitioner if you have not done so yet. They contain very important materials such as review materials that will be crucial for passing the exam.
The FREE AWS Exam Readiness course, official AWS sample questions, Whitepapers, FAQs, AWS Documentation, Re:Invent videos, forums, labs, AWS cheat sheets, AWS practice exams, and personal experiences are what you will need to pass the exam. Since the SA Pro is one of the most difficult AWS certification exams out there, you have to prepare yourself with every study material you can get your hands on. To learn more details regarding your exam, go through this AWS exam blueprint as it discusses the various domains they will test you on.
AWS has a digital course called Exam Readiness: AWS Certified Solutions Architect – Professional, which is a short video lecture that discusses what to expect on the AWS Certified Solutions Architect – Professional exam. It should sufficiently provide an overview of the different concepts and practices that you’ll need to know about. Each topic in the course will also contain a short quiz right after you finish its lecture to help you lock in the important information.

AWS Services to Focus On
Generally, as a soon-to-be AWS Certified SA Pro, you should have a thorough understanding of every service and feature in AWS. But for the purpose of this review, give more attention on the following services since they are common topics in the SA Pro exams:
- AWS Organizations
- Know how to create organizational units (OUs), service control policies (SCPs), and any additional parameters in AWS Organizations. Different SCP from IAM policies. Read how you can save on costs by enabling consolidated billing in your organizations.
- There might be scenarios where the master account needs access to member accounts. Your options can include setting up OUs and SCPs, delegating an IAM role, or providing cross account access.
- Differentiate SCP from IAM policies.
- You should also know how to integrate AWS Organizations with other services such as CloudFormation, Service Catalog, and IAM to manage resources and user access.
- Lastly, read how you can save on costs by enabling consolidated billing in your organizations, and what would be the benefits of enabling all features.
- AWS Server Migration Services
- AWS Database Migration Service + Schema Conversion Tool
- Aside from server and application migration, you should also know how you can move on-premises databases to AWS, and not just to RDS but to other services as well as Aurora and RedShift.
- Read over what schemas can be converted by SCT.
- AWS Serverless Application Model
- The AWS SAM has a syntax of its own. Study the syntax and how AWS SAM is used to deploy serverless applications through code.
- Know the relationship between SAM and CloudFormation. Hint: You can use these two together.
- AWS EC2 Systems Manager
- Study the different features under Systems Manager and how each feature can automate EC2-related processes. Patch Manager and Maintenance Windows are often used together to perform automated patching. It allows for easier setup and better control over patch baselines, rather than using a cron job within an EC2 instance or using Cloudwatch Events.
- It is also important to know how you can troubleshoot EC2 issues using Systems Manager.
- Parameter Store allows you to securely store a string in AWS, which can be retrieved anywhere in your environment. You can use this service instead of AWS Secrets Manager if you don’t need to rotate your secrets.
- AWS CI/CD – Study the different CI/CD tools in AWS, from function to features to implementation. It would be very helpful if you can create your own CI/CD pipeline as well using the services below.
- AWS Service Catalog
- This service is also part of the automation toolkit in AWS. Study how you can create and manage portfolios of approved services in Service Catalog, and how you can integrate these with other technologies such as AWS Organizations.
- You can enforce tagging on services using service catalog. This way, users can only launch resources that have the tags you defined.
- Know when Service Catalog is a better option for resource control rather than AWS Cloudformation. A good example is when you want to create a customized portfolio for each type of user in an organization and selectively grant access to the appropriate portfolio.
- AWS Direct Connect (DX)
- You should have a deep understanding of this service. Questions commonly include Direct Connect Gateway, public and private VIFs and LAGs.
- Direct Connect is commonly used for connecting on-premises networks to AWS, but it can also be used to connect different AWS Regions to a central datacenter. For these kinds of scenarios, take note of the benefits of Direct Connect such as dedicated bandwidth, network security, multi-Region and multi-VPC connection support.
- Direct Connect is also used along with a failover connection, such as a secondary DX line or IPsec VPN. The correct answer will depend on specific requirements like cost, speed, ease of management, etc.
- Another combination that can be used to link different VPCs is Transit Gateway + DX.
- AWS CloudFormation – Your AWS exam might include a lot of scenarios that involve Cloudformation, so take note of the following:
- You can use CloudFormation to enforce tagging by requiring users to only use resources that CloudFormation launched.
- CloudFormation can be used for managing resources across different AWS accounts in an Organization using StackSets.
- CloudFormation is often compared to AWS Service Catalog and AWS SAM. The way to approach this in the exam is to know what features are supported by CloudFormation that cannot be performed in a similar fashion with Service Catalog or SAM.
- Amazon VPC (in depth)
- Know the ins and outs of NAT Gateways and NAT instances, such as supported IP protocols, which types of packets are dropped in a cut connection, etc.
- Study about transit gateway and how it can be used together with direct connect.
- Remember longest prefix routing.
- Compare VPC peering to other options such as Site to Site VPN. Know what components are in use: Customer gateway, Virtual Private Gateway, etc.
- Amazon ECS
- Differentiate task role from task execution role.
- Compare using ECS compute instances from Fargate serverless model.
- Study how to link together ECS and ECR with CI/CD tools to automate deployment of updates to your Docker containers.
- Elastic Load Balancer (in depth)
- Differentiate the internet protocols used by each type of ELB for listeners and target groups: HTTP, HTTPS, TCP, UDP, TLS.
- Know how you can configure load balancers to forward client IP to target instances.
- Know how you can secure your ELB traffic through the use of SSL and WAF. SSL can be offloaded on either the ELB or CloudHSM.
- Elastic Beanstalk
- Study the different deployment options for Elastic Beanstalk.
- Know the steps in performing a blue/green deployment.
- Know how you can use traffic splitting deployment to perform canary testing
- Compare Elastic Beanstalk’s deployment options to CodeDeploy.
- WAF and Shield
- Know at what network layer do WAF and Shield operate in
- Differentiate security capabilities of WAF and Shield Advanced, especially with regards to DDoS protection. A great way to determine which one to use is to look at the services that need the protection and if cost is a factor. You may also visit this AWS documentation for additional details.
- Amazon Workspaces vs Amazon Appstream
- Workspaces is best for virtual desktop environments. You can use it to provision either Windows or Linux desktops in just a few minutes and quickly scale to provide thousands of desktops to workers across the globe.
- Appstream is best for standalone desktop applications. You centrally manage your desktop applications on AppStream 2.0 and securely deliver them to any computer.
- Amazon Workdocs – It is important to determine what features makes Workdocs unique compared to using S3 and EFS. Choose this service if you need a secure document storage where you can collaborate in real-time with others and manage access to the documents.
- Elasticache vs DAX vs Aurora Read Replicas
- Know your caching options especially when it comes to databases.
- If there is a feature that is readily integrated with the database, it would be better to use that integrated features instead for less overhead.
- Snowball Edge vs Direct Connect vs S3 Acceleration – These three services are heavily used for data migration purposes. Read the exam scenario properly to determine which service is best used. Factors in choosing the correct answer are cost, time allotted for the migration, and how much data is needed to be transported.
- Using Resource Tags with IAM – Study how you can use resource tags to manage access via IAM policies.
We also recommend checking out Tutorials Dojo’s AWS Cheat Sheets which provides a summarized but highly informative set of notes and tips for your review on these services. These cheat sheets are presented mostly in bullet points which will help you retain the knowledge much better vs reading the lengthy FAQs.
We expect that you already have vast knowledge on the AWS services that a Solutions Architect commonly use, such as those listed in our SA Associate review guide. It is also not enough to just know the service and its features. You should also have a good understanding on how to integrate these services with one another to build large-scale infrastructures and applications. It’s why it is generally recommended to have hands-on experience managing and operating systems on AWS.
Validate Your Knowledge
After your review, you should take some practice tests to measure your preparedness for the real exam. AWS offers a sample practice test for free which you can find here. You can also opt to buy the longer AWS sample practice test at aws.training, and use the discount coupon you received from any previously taken certification exams. Be aware though that the sample practice tests do not mimic the difficulty of the real SA Pro exam. You should not rely solely on them to gauge your preparedness. It is better to take more practice tests to fully understand if you are prepared to pass the certification exam.
Fortunately, Tutorials Dojo also offers a great set of practice questions for you to take here. It is kept updated by the creators to ensure that the questions match what you’ll be expecting in the real exam. The practice tests will help fill in any important details that you might have missed or skipped in your review.
Sample Practice Test Questions:
The AWS resources in your production account is shared among various business units of the company. A single business unit may have one or more AWS accounts which have resources in the production account. There were a lot of incidents in which the developers from a specific business unit accidentally terminated the EC2 instances owned by another business unit. You are tasked to come up with a solution to only allow a specific business unit who own the EC2 instances, and other AWS resources, to terminate their own resources.
Which of the following is the most suitable multi-account strategy that you should implement?
- Use AWS Organizations to centrally manage all of your accounts. Group your accounts, which belongs to a specific business unit, to individual Organization Unit (OU). Create an IAM Role in the production account for each business unit which has a policy that allows access to the EC2 instances including a resource-level permission to terminate the instances that it owns. Create an
AWSServiceRoleForOrganizationsservice-linked role to the individual member accounts of the OU to enable trusted access.
- Use AWS Organizations to centrally manage all of your accounts. Group your accounts, which belongs to a specific business unit, to individual Organization Unit (OU). Create a Service Control Policy in the production account for each business unit which has a policy that allows access to the EC2 instances including a resource-level permission to terminate the instances that it owns. Provide the cross-account access and the SCP to the individual member accounts to tightly control who can terminate the EC2 instances.
- Use AWS Organizations to centrally manage all of your accounts. Group your accounts, which belong to a specific business unit, to individual Organization Units (OU). Create an IAM Role in the production account which has a policy that allows access to the EC2 instances including a resource-level permission to terminate the instances owned by a particular business unit. Provide the cross-account access and the IAM policy to every member accounts of the OU.
- Use AWS Organizations to centrally manage all of your accounts. Group your accounts, which belongs to a specific business unit, to individual Organization Unit (OU). Create a Service Control Policy in the production account which has a policy that allows access to the EC2 instances including a resource-level permission to terminate the instances owned by a particular business unit. Provide the cross-account access and the SCP to the OUs, which will then be automatically inherited by its member accounts.
A known security vulnerability was discovered in the outdated Operating System of your company’s EC2 fleet. As the Systems Administrator, you are responsible in mitigating the vulnerability as soon as possible to safeguard your systems from various cyber security attacks. In addition, you are also required to record all of the changes to patch and association compliance statuses.
What is the most efficient way to solve this issue?
- Configure the EC2 fleet to automatically install the security OS patch every week on the provided maintenance window.
- Use AWS Systems Manager and AWS Config to manage, record, and deploy the security patches for the OS for the entire fleet of EC2 instances.
- Set up Amazon QuickSight and Kibana to apply, monitor, and visualize the patch statuses of all EC2 instances.
- Use AWS Systems Manager and Amazon ES to manage, record, and deploy the security patches for the OS for the entire fleet of EC2 instances.
In general, what you should have learned from your review are the following:
- Features and use cases of the AWS services and how they integrate with each other
- AWS networking, security, billing and account management
- The AWS CLI, APIs and SDKs
- Automation, migration planning, and troubleshooting
- The best practices in designing solutions in the AWS Cloud

Final notes regarding your exam
The SA Professional exam questions always ask for highly available, fault tolerant, cost-effective and secure solutions. Be sure to understand the choices provided to you, and verify that they have accurate explanations. Some choices are very misleading such that they seem to be the most natural answer to the question, but actually contain incorrect information, such as the incorrect use of a service. Always place accuracy above all else.
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.
Since an SA Professional has responsibilities in creating large-scale architectures, be wary of the different ways AWS services can be integrated with one another. Common combinations include:
- Lambda, API Gateway, SNS, and DynamoDB
- EC2, EBS/EFS/Elasticache, Auto Scaling, ELB, and SQS
- S3, Cloudfront, WAF
- S3, Kinesis
- On-premises servers with Direct Connect/VPN/VPC Endpoints/Transit Gateway
- Organizations, SSO, IAM roles, Config, Cloudformation and Service Catalog
- Mobile apps with Cognito, API Gateway, and DynamoDB
- CodeCommit, CodePipeline, CodeBuild, CodeDeploy
- ECR, ECS/Fargate and S3
- EMR + Spot Fleets/Combinations of different instance types for master node and task nodes
- Amazon Connect + Alexa + Amazon Lex
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.
