Difference between the SOA-C02 and SOA-C03 AWS Certified CloudOps Engineer Associate Exam Versions

Before you start preparing for the exam, it is essential to understand the key knowledge areas and topics of the new AWS Certified CloudOps Engineer – Associate SOA-C03 exam and the differences from the previous SOA-C02 version. Knowing these differences helps you focus your study plan on relevant and updated content according to the latest AWS cloud operations practices.

The exam domains of the SOA-C02 and SOA-C03 are similar in purpose but have been reorganized and updated to reflect modern cloud operations better. The SOA-C03 exam renames the certification to “CloudOps Engineer” to emphasize evolving industry roles from traditional systems administration (SysOps). The new SOA-C03 exam has consolidated some domains and introduced additional emphasis on automation, container services, and multi-account/multi-Region operations.

One of the main differences between the two exams is the inclusion of container technologies such as Amazon ECR and Amazon EKS in the SOA-C03 exam scope, which were out of scope in the SOA-C02 exam. Additionally, the SOA-C03 exam covers more infrastructure as code (IaC) concepts, including the usage of AWS CDK and third-party tools like Terraform and Git, reflecting the rise in cloud automation and deployment pipelines.

SOA-C02 VS. SOA-C03 EXAM DOMAIN COMPARISON TABLE

Another significant change is the updated percentage weighting of exam domains. The SOA-C03 exam places more focus on Monitoring, Logging, Analysis, Remediation, and Performance Optimization combined into a single domain with 22% , whereas the SOA-C02 exam separates them. The coverage percentage for Reliability and Business Continuity, and Deployment, Provisioning, and Automation has increased in SOA-C03, showing a stronger emphasis on these areas. Lastly, both exam versions retain the same percentage coverage in the Security and Compliance and Networking and Content Delivery domains.

AWS Certified CloudOps Engineer Associate SOA-C03 Practice Exam

 

Sample Practice Questions For SOA-C03 Exam:

Question 1

A financial start-up has recently adopted a hybrid cloud infrastructure with AWS Cloud. They are planning to migrate their online payments system that supports an IPv6 address and uses an Oracle database in a RAC configuration. As the AWS Consultant, you have to make sure that the application can initiate outgoing traffic to the Internet but blocks any incoming connection from the Internet.

Which of the following options would you do to properly migrate the application to AWS?

  1. Migrate the Oracle database to an EC2 instance. Launch an EC2 instance to host the application and then set up a NAT Instance.
  2. Migrate the Oracle database to RDS. Launch an EC2 instance to host the application and then set up a NAT gateway instead of a NAT instance for better availability and higher bandwidth.
  3. Migrate the Oracle database to RDS. Launch the application on a separate EC2 instance and then set up a NAT Instance.
  4. Migrate the Oracle database to an EC2 instance. Launch the application on a separate EC2 instance and then set up an egress-only Internet gateway.

Correct Answer: 4

An egress-only Internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows outbound communication over IPv6 from instances in your VPC to the Internet, and prevents the Internet from initiating an IPv6 connection with your instances.

An instance in your public subnet can connect to the Internet through the Internet gateway if it has a public IPv4 address or an IPv6 address. Similarly, resources on the Internet can initiate a connection to your instance using its public IPv4 address or its IPv6 address; for example, when you connect to your instance using your local computer.

IPv6 addresses are globally unique, and are therefore public by default. If you want your instance to be able to access the Internet but want to prevent resources on the Internet from initiating communication with your instance, you can use an egress-only Internet gateway. To do this, create an egress-only Internet gateway in your VPC, and then add a route to your route table that points all IPv6 traffic (::/0) or a specific range of IPv6 address to the egress-only Internet gateway. IPv6 traffic in the subnet that’s associated with the route table is routed to the egress-only Internet gateway.

Remember that a NAT device in your private subnet does not support IPv6 traffic. As an alternative, create an egress-only Internet gateway for your private subnet to enable outbound communication to the Internet over IPv6 and prevent inbound communication. An egress-only Internet gateway supports IPv6 traffic only.

Take note that the application that will be migrated is using an Oracle database on a RAC configuration, which is not supported by RDS.

Hence, the correct answer is: Migrate the Oracle database to an EC2 instance. Launch the application on a seperate EC2 instance and then set-up an egress-only Internet gateway.

The options that say: Migrate the Oracle database to an EC2 instance. Launch an EC2 instance to host the application and then set up a NAT instance and Migrate the Oracle database to RDS. Launch the application on a seperate EC2 instance and then set up a NAT instance are incorrect because a NAT instance are incorrect because a NAT instance does not support IPv6 address. You have to use an egress-only Internet gateway instead. In addition, RDS does not support Oracle RAC, which is why, you have to launch the database in an EC2 instance.

The options that say: Migrating the Oracle database to RDS.  Launch an EC2 instance to host the application and then setting up a NAT gateway instead of a NAT instance for better availability and higher bandwith is incorrect as RDS does not support Oracle RAC. Although it is true that NAT Gateway provides better availability and higher bandwidth than NAT instance, it still does not support IPv6 address, unlike an egress-only Internet gateway.

Question 2

A leading tech consultancy firm has an AWS Virtual Private Cloud (VPC) with one public subnet. They have recently deployed a new blockchain application to an EC2 instance. After a month, management has decided that the application should be modified to also support IPv6 addresses.

Which of the following should you do to satisfy the requirement?

Option 1:

  1. Associate an IPv6 Gateway with your VPC and Subnets

  2. Update the Route Tables and Security Group Rules

  3. Enable Enhanced Networking in your EC2 instance

  4. Assign IPv6 Addresses to the EC2 Instance

Option 2:

  1. Attach an Egress-Only Internet Gateway to the VPC and Subnets

  2. Update the Route Tables

  3. Update the Security Group Rules

  4. Assign IPv6 Addresses to the EC2 instance

Option 3:

  1. Associate an IPv6 CIDR Block with the VPC and Subnets

  2. Update the Route Tables

  3. Update the Security Group Rules

  4. Assign IPv6 Addresses to the EC2 Instance

Option 4:

  1. Enable Enhanced Networking in your EC2 instance

  2. Update the Route Tables

  3. Update the Security Group Rules

  4. Assign IPv6 Addresses to the EC2 Instance

Correct Answer: 3

If you have an existing VPC that supports IPv4 only, and resources in your subnet that are configured to use IPv4 only, you can enable IPv6 support for your VPC and resources. Your VPC can operate in dual-stack mode — your resources can communicate over IPv4, or IPv6, or both. IPv4 and IPv6 communication are independent of each other. You cannot disable IPv4 support for your VPC and subnets; this is the default IP addressing system for Amazon VPC and Amazon EC2.

The following provides an overview of the steps to enable your VPC and subnets to use IPv6:

Step 1:

Associate an IPv6 CIDR Block with Your VPC and Subnets – Associate an Amazon-provided IPv6 CIDR block with your VPC and with your subnets.

Step 2:

Update Your Route Tables – Update your route tables to route your IPv6 traffic. For a public subnet, create a route that routes all IPv6 traffic from the subnet to the Internet gateway. For a private subnet, create a route that routes all Internet-bound IPv6 traffic from the subnet to an egress-only Internet gateway.

Step 3:

Update Your Security Group Rules – Update your security group rules to include rules for IPv6 addresses. This enables IPv6 traffic to flow to and from your instances. If you’ve created custom network ACL rules to control the flow of traffic to and from your subnet, you must include rules for IPv6 traffic.

Step 4:

Assign IPv6 Addresses to Your Instances – Assign IPv6 addresses to your instances from the IPv6 address range of your subnet.

Hence, the correct answer is:

1. Associate an IPv6 CIDR Block with the VPC and Subnets

2. Update the Route Tables

3. Update the Security Group Rules

4. Assign IPv6 Addresses to the EC2 Instance

The option with the step that says: Enable Enhanced Networking in your EC2 instance is incorrect because this is not required to enable IPv6. You also don’t need to associate an IPv6 Gateway with your VPC and Subnets. What you need to do is to associate an IPv6 CIDR Block, not an IPv6 Gateway.

The option with the step that says: Associate a NAT Gateway with your VPC and Subnets is incorrect. First, a NAT Gateway is mainly used to allow instances in a private subnet to initiate outbound internet traffic but does not facilitate inbound traffic, which is not directly related to supporting IPv6 for both inbound and outbound connectivity. Additionally, Enhanced Networking just improves network performance for EC2 instances through higher bandwidth and lower latency but it does not relate to the management of IPv6 addresses.

The option with the step that says: Attach an Egress-Only Internet Gateway to the VPC and Subnets is incorrect because this type of gateway simply enables outbound-only access to the Internet over IPv6 from your VPC. The use of an Egress-Only Internet Gateway is not warranted in this scenario.
