Infrastructure Security, Identity and Access Management, and Data Protection typically account for a significant portion of the exam. However, all six domains are important, AWS tests depth across threat detection, logging, and governance to ensure you can manage security holistically. Focus on understanding how these domains interconnect rather than treating them as isolated topics.
In practice, these domains work together in a continuous cycle. Identity and Access Management controls who can access resources; Infrastructure Security and Data Protection secure those resources; Security Logging and Monitoring track all activity; Threat Detection and Incident Response identify and remediate issues; and Management and Security Governance ensures compliance and policy enforcement. Understanding these workflows helps you answer scenario-based questions accurately.
AWS recommends at least two years of hands-on security experience with AWS services. Ideally, you should have practical experience configuring IAM policies, setting up encryption, implementing security groups, and reviewing CloudTrail logs. If you lack this experience, prioritize labs on CloudTrail, GuardDuty, KMS, and IAM policy simulation to build confidence before the exam.
Candidates often confuse similar services (e.g., Security Groups vs. NACLs, or KMS vs. S3 encryption options), misunderstand IAM policy evaluation logic, or overlook the principle of least privilege in access control scenarios. Another frequent error is not reading scenario questions carefully, details about compliance requirements, account structure, or existing infrastructure often determine the correct answer. Take time to identify the constraint or requirement before selecting your response.
In your final week, focus on weak domains identified during practice tests rather than re-reading all material. Run one or two full-length timed practice tests to assess pacing and identify remaining gaps. Review explanations for questions you missed, not just correct answers. On the day before the exam, do a light review of key definitions and workflows, then rest well, mental clarity matters more than last-minute cramming.
[Infrastructure Security]
A company has a batch-processing system that uses Amazon S3, Amazon EC2, and AWS Key Management Service (AWS KMS). The system uses two AWS accounts: Account A and Account B.
Account A hosts an S3 bucket that stores the objects that will be processed. The S3 bucket also stores the results of the processing. All the S3 bucket objects are encrypted by a KMS key that is managed in
Account A.
Account B hosts a VPC that has a fleet of EC2 instances that access the S3 buck-et in Account A by using statements in the bucket policy. The VPC was created with DNS hostnames enabled and DNS resolution enabled.
A security engineer needs to update the design of the system without changing any of the system's code. No AWS API calls from the batch-processing EC2 in-stances can travel over the internet.
Which combination of steps will meet these requirements? (Select TWO.)
[Identity and Access Management]
A company has an AWS Key Management Service (AWS KMS) customer managed key with imported key material Company policy requires all encryption keys to be rotated every year
What should a security engineer do to meet this requirement for this customer managed key?
To meet the requirement of rotating the AWS KMS customer managed key every year, the most appropriate solution would be to enable automatic key rotation annually for the existing customer managed key. This will ensure that AWS KMS generates new cryptographic material for the CMK every year. AWS KMS also saves the CMK's older cryptographic material in perpetuity so it can be used to decrypt data that it encrypted. AWS KMS does not delete any rotated key material until you delete the CMK.

[Identity and Access Management]
A company is expanding its group of stores. On the day that each new store opens, the company wants to launch a customized web application for that store. Each store's application will have a non-production environment and a production environment. Each environment will be deployed in a separate AWS account. The company uses AWS Organizations and has an OU that is used only for these accounts.
The company distributes most of the development work to third-party development teams. A security engineer needs to ensure that each team follows the company's
deployment plan for AWS resources. The security engineer also must limit access to the deployment plan to only the developers who need access. The security engineer already has created an AWS CloudFormation template that implements the deployment plan.
What should the security engineer do next to meet the requirements in the MOST secure way?
The correct answer is A. Create an AWS Service Catalog portfolio in the organization's management account. Upload the CloudFormation template. Add the template to the portfolio's product list. Share the portfolio with the OU.
According to the AWS documentation, AWS Service Catalog is a service that allows you to create and manage catalogs of IT services that are approved for use on AWS. You can use Service Catalog to centrally manage commonly deployed IT services and help achieve consistent governance and compliance requirements, while enabling users to quickly deploy only the approved IT services they need.
To use Service Catalog with multiple AWS accounts, you need to enable AWS Organizations with all features enabled. This allows you to centrally manage your accounts and apply policies across your organization. You can also use Service Catalog as a service principal for AWS Organizations, which lets you share your portfolios with organizational units (OUs) or accounts in your organization.
To create a Service Catalog portfolio, you need to use an administrator account, such as the organization's management account. You can upload your CloudFormation template as a product in your portfolio, and define constraints and tags for it. You can then share your portfolio with the OU that contains the accounts for the web applications. This will allow the developers in those accounts to launch products from the shared portfolio using the Service Catalog end user console.
Option B is incorrect because CloudFormation modules are reusable components that encapsulate one or more resources and their configurations. They are not meant to be used as templates for deploying entire stacks of resources. Moreover, sharing a module with an OU does not grant access to launch stacks from it.
Option C is incorrect because creating an IAM role that has a trust policy that allows cross-account access to the portfolio is not secure. It would allow any user in the OU accounts to assume the role and access the portfolio, regardless of their job function or access requirements.
Option D is incorrect because sharing a module with an OU does not grant access to launch stacks from it. It also does not limit access to the deployment plan to only the developers who need access.
[Identity and Access Management]
You need to create a policy and apply it for just an individual user. How could you accomplish this in the right way?
Please select:
Options A and B are incorrect since you need to add an inline policy just for the user
Option C is invalid because you don't assign an IAM role to a user
The IAM Documentation mentions the following
An inline policy is a policy that's embedded in a principal entity (a user, group, or role)---that is, the policy is an inherent part of the principal entity. You can create a policy and embed it in a principal entity, either when you create the principal entity or later.

The correct answer is: Add an inline policy for the user Submit your Feedback/Queries to our Experts
[Identity and Access Management]
A security engineer needs to implement a write-once-read-many (WORM) model for data that a company will store in Amazon S3 buckets. The company uses the S3 Standard storage class for all of its S3 buckets. The security engineer must en-sure that objects cannot be overwritten or deleted by any user, including the AWS account root user.
