AWS Certified DevOps Engineer Professional Exam Study Path

This certification is the pinnacle of your DevOps career in AWS. The AWS Certified DevOps Engineer Professional (or AWS DevOps Pro) is the advanced certification of both AWS SysOps Administrator Associate and AWS Developer Associate. This is similar to how the AWS Solutions Architect Professional role is a more advanced version of the AWS Solutions Architect Associate. 

Generally, AWS recommends that you first take (and pass) both AWS SysOps Administrator Associate and AWS Developer Associate certification exams before taking on this certification. Previously, it was a prerequisite that you obtain the associate level certifications before you are allowed to go for the professional level. Last October 2018, AWS removed this ruling to provide customers a more flexible approach to the certifications. 

Study Materials

The FREE AWS Exam Readiness course, official AWS sample questions, Whitepapers, FAQs, AWS Documentation, Re:Invent videos, forums, labs, AWS cheat sheets, practice tests, and personal experiences are what you will need to pass the exam. Since the DevOps 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. If you need a review on the fundamentals of AWS DevOps, then do check out our review guides for the AWS SysOps Administrator Associate and AWS Developer Associate certification exams. Also, visit this AWS exam blueprint to learn more details about your certification exam.

For virtual classes, you can attend the DevOps Engineering on AWS and Systems Operations on AWS classes since they will teach you concepts and practices that are expected to be in your exam.

For whitepapers, focus on the following:

  1. Running Containerized Microservices on AWS
  2. Microservices on AWS
  3. Infrastructure as Code
  4. Introduction to DevOps
  5. Practicing Continuous Integration and Continuous Delivery on AWS
  6. Jenkins on AWS
  7. Blue/Green Deployments on AWS whitepaper
  8. Import Windows Server to Amazon EC2 with PowerShell
  9. Development and Test on AWS
  10. IT Certification Category (English)728x90

Almost all online training you need can be found on the AWS web page. One digital course that you should check out is the Exam Readiness: AWS Certified DevOps Engineer – Professional course. This digital course contains lectures on the different domains of your exam, and they also provide a short quiz right after each lecture to validate what you have just learned.

Lastly, do not forget to study the AWS CLI, SDKs, and APIs. Since the DevOps Pro is also an advanced certification for Developer Associate, you need to have knowledge of programming and scripting in AWS. Go through the AWS documentation to review the syntax of CloudFormation template, Serverless Application Model template, CodeBuild buildspec, CodeDeploy appspec, and IAM Policy.

AWS Services to Focus On

Since this exam is a professional level one, you should already have a deep understanding of the AWS services listed under our SysOps Administrator Associate and Developer Associate review guides. In addition, you should familiarize yourself with the following services since they commonly come up in the DevOps Pro exam: 

  1. AWS CloudFormation
  2. AWS Lambda
  3. Amazon CloudWatch Events
  4. Amazon CloudWatch Alarms
  5. AWS CodePipeline
  6. AWS CodeDeploy
  7. AWS CodeBuild
  8. AWS CodeCommit
  9. AWS Config
  10. AWS Systems Manager
  11. Amazon ECS
  12. Amazon Elastic Beanstalk
  13. AWS CloudTrail
  14. AWS OpsWorks
  15. AWS Trusted Advisor

The FAQs provide a good summary for each service, however, the AWS documentation contains more detailed information that you’ll need to study. These details will be the deciding factor in determining the correct choice from the incorrect choices in your exam. To supplement your review of the services, we recommend that you take a look at Tutorials Dojo’s AWS Cheat Sheets. Their contents are well-written and straight to the point, which will help reduce the time spent going through FAQs and documentations.

Sample Practice Test Questions:

Question 1

An application is hosted in an Auto Scaling group of Amazon EC2 instances with public IP addresses in a public subnet. The instances are configured with a user data script that fetches and installs the required system dependencies of the application from the Internet upon launch. A change was recently introduced to prohibit any Internet access from these instances to improve the security but after its implementation, the instances could not get the external dependencies anymore. Upon investigation, all instances are properly running but the hosted application is not starting up completely due to the incomplete installation.

Which of the following is the MOST secure solution to solve this issue and also ensure that the instances do not have public Internet access?

  1. Download all of the external application dependencies from the public Internet and then store them in an S3 bucket. Set up a VPC endpoint for the S3 bucket and then assign an IAM instance profile to the instances in order to allow them to fetch the required dependencies from the bucket.
  2. Deploy the Amazon EC2 instances in a private subnet and associate Elastic IP addresses on each of them. Run a custom shell script to disassociate the Elastic IP addresses after the application has been successfully installed and is running properly.
  3. Use a NAT gateway to disallow any traffic to the VPC which originated from the public Internet. Deploy the Amazon EC2 instances to a private subnet then set the subnet’s route table to use the NAT gateway as its default route.
  4. Set up a brand new security group for the Amazon EC2 instances. Use a whitelist configuration to only allow outbound traffic to the site where all of the application dependencies are hosted. Delete the security group rule once the installation is complete. Use AWS Config to monitor the compliance.

Correct Answer: 1

A VPC endpoint enables you to privately connect your VPC to supported AWS services and VPC endpoint services powered by PrivateLink without requiring an Internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC do not require public IP addresses to communicate with resources in the service. Traffic between your VPC and the other service does not leave the Amazon network.

Endpoints are virtual devices. They are horizontally scaled, redundant, and highly available VPC components that allow communication between instances in your VPC and services without imposing availability risks or bandwidth constraints on your network traffic.

There are two types of VPC endpoints: interface endpoints and gateway endpoints. You can create the type of VPC endpoint required by the supported service. S3 and DynamoDB are using Gateway endpoints while most of the services are using Interface endpoints.

You can use an S3 bucket to store the required dependencies and then set up a VPC Endpoint to allow your EC2 instances to access the data without having to traverse the public Internet.

Hence, the correct answer is the option that says: Download all of the external application dependencies from the public Internet and then store them to an S3 bucket. Set up a VPC endpoint for the S3 bucket and then assign an IAM instance profile to the instances in order to allow them to fetch the required dependencies from the bucket.

The option that says: Deploy the Amazon EC2 instances in a private subnet and associate Elastic IP addresses on each of them. Run a custom shell script to disassociate the Elastic IP addresses after the application has been successfully installed and is running properly is incorrect because it is possible that the custom shell script may fail and the disassociation of the Elastic IP addresses might not be fully implemented which will allow the EC2 instances to access the Internet.

The option that says: Use a NAT gateway to disallow any traffic to the VPC which originated from the public Internet. Deploy the Amazon EC2 instances to a private subnet then set the subnet’s route table to use the NAT gateway as its default route is incorrect because although a NAT Gateway can safeguard the instances from any incoming traffic that were initiated from the Internet, it still permits them to send outgoing requests externally.

The option that says: Set up a brand new security group for the Amazon EC2 instances. Use a whitelist configuration to only allow outbound traffic to the site where all of the application dependencies are hosted. Delete the security group rule once the installation is complete. Use AWS Config to monitor the compliance is incorrect because this solution has a high operational overhead since the actions are done manually. This is susceptible to human error such as in the event that the DevOps team forgets to delete the security group. The use of AWS Config will just monitor and inform you about the security violation but it won’t do anything to remediate the issue.

Question 2

Due to the growth of its regional e-commerce website, the company has decided to expand its operations globally in the coming months ahead. The REST API web services of the app is currently running in an Auto Scaling group of EC2 instances across multiple Availability Zones behind an Application Load Balancer. For its database tier, the website is using a single Amazon Aurora MySQL database instance in the AWS Region where the company is based. The company wants to consolidate and store the data of its offerings into a single data source for its product catalog across all regions. For data privacy compliance, they need to ensure that the personal information of their users, as well as their purchases and financial data, are kept in their respective regions.

Which of the following options can meet the above requirements and entails the LEAST amount of change to the application?

  1. Set up a new Amazon Redshift database to store the product catalog. Launch a new set of Amazon DynamoDB tables to store the personal information and financial data of their customers.
  2. Set up a DynamoDB global table to store the product catalog data of the e-commerce website. Use regional DynamoDB tables for storing the personal information and financial data of their customers.
  3. Set up multiple read replicas in your Amazon Aurora cluster to store the product catalog data. Launch an additional local Amazon Aurora instances in each AWS Region for storing the personal information and financial data of their customers.
  4. Set up multiple read replicas in your Amazon Aurora cluster to store the product catalog data. Launch a new DynamoDB global table for storing the personal information and financial data of their customers.

Tutorials Dojo Study Guide and Cheatsheet

Correct Answer: 3

An Aurora global database consists of one primary AWS Region where your data is mastered, and one read-only, secondary AWS Region. Aurora replicates data to the secondary AWS Region with typical latency of under a second. You issue write operations directly to the primary DB instance in the primary AWS Region. An Aurora global database uses dedicated infrastructure to replicate your data, leaving database resources available entirely to serve application workloads. Applications with a worldwide footprint can use reader instances in the secondary AWS Region for low latency reads. In the unlikely event your database becomes degraded or isolated in an AWS region, you can promote the secondary AWS Region to take full read-write workloads in under a minute.

The Aurora cluster in the primary AWS Region where your data is mastered performs both read and write operations. The cluster in the secondary region enables low-latency reads. You can scale up the secondary cluster independently by adding one or more DB instances (Aurora Replicas) to serve read-only workloads. For disaster recovery, you can remove and promote the secondary cluster to allow full read and write operations.

Only the primary cluster performs write operations. Clients that perform write operations connect to the DB cluster endpoint of the primary cluster.

Hence, the correct answer is: Set up multiple read replicas in your Amazon Aurora cluster to store the product catalog data. Launch an additional local Amazon Aurora instances in each AWS Region for storing the personal information and financial data of their customers.

The option that says: Set up a new Amazon Redshift database to store the product catalog. Launch a new set of Amazon DynamoDB tables to store the personal information and financial data of their customers is incorrect because this solution entails a significant overhead of refactoring your application to use Redshift instead of Aurora. Moreover, Redshift is primarily used as a data warehouse solution and not suitable for OLTP or e-commerce websites.

The option that says: Set up a DynamoDB global table to store the product catalog data of the e-commerce website. Use regional DynamoDB tables for storing the personal information and financial data of their customers is incorrect because although the use of Global and Regional DynamoDB is acceptable, this solution still entails a lot of changes to the application. There is no assurance that the application can work with a NoSQL database and even so, you have to implement a series of code changes in order for this solution to work.

The option that says: Set up multiple read replicas in your Amazon Aurora cluster to store the product catalog data. Launch a new DynamoDB global table for storing the personal information and financial data of their customers is incorrect because although the use of Read Replicas is appropriate, this solution still requires you to do a lot of code changes since you will use a different database to store your regional data.
