This free SCS-C02 practice test mirrors the structure and difficulty of the real AWS Certified Security Specialty SCS-C02 exam. Every question is written against the official 2026 exam blueprint published by Amazon Web Services, ensuring you practise exactly what the exam tests — not last year's objectives.
The SCS-C02 blueprint is divided into 6weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Infrastructure Security and Security Logging and Monitoring contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
SCS-C02 Exam Blueprint — 6 Domains
Threat Detection and Incident Response

Identity and Access Management
Management and Security Governance
Infrastructure Security
Data Protection
28 numbered sets, 6 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass SCS-C02 on their first attempt:
Answer before revealing
Read each SCS-C02 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which SCS-C02 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real SCS-C02 gives you roughly 2.6 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass SCS-C02 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 376+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 6 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.

A company runs a multi-account AWS environment using AWS Organizations. The security team needs to implement centralized logging for all AWS CloudTrail events across all accounts. They create a new trail in the management account with the following configuration: trail name 'central-trail', apply to all accounts in the organization, enable data events for all S3 buckets, and store logs in a centralized S3 bucket. After one week, they notice that some accounts are not delivering CloudTrail logs to the central bucket. The security engineer verifies that the trail is still configured to apply to all accounts and that the S3 bucket policy allows cross-account access. What is the MOST likely reason for the missing logs?

A global e-commerce company operates in three AWS Regions: us-east-1, eu-west-1, and ap-southeast-1. The company uses AWS Organizations with 50 member accounts grouped by business unit. The security team recently discovered that several S3 buckets containing customer data were accidentally made public due to misconfigured bucket policies. The team wants to implement a preventive control that blocks any S3 bucket from becoming public across all accounts, while still allowing authorized cross-account access. The solution must be centrally managed and not require changes to existing IAM policies. Additionally, the team needs to be notified immediately when a public bucket is attempted. Which solution meets all requirements?
Select an answer to reveal the explanation
A company uses AWS Organizations with multiple accounts and wants to ensure that all newly created S3 buckets have encryption enabled. The Security team needs a solution that automatically remediates non-compliant buckets without manual intervention. What should they do?

A security engineer is troubleshooting connectivity issues between an Amazon EC2 instance in a VPC and an on-premises server over a Direct Connect virtual interface. The EC2 instance has a security group that allows outbound traffic to the on-premises CIDR block (10.0.0.0/16). The VPC has a route table entry pointing the on-premises CIDR to the virtual private gateway. The on-premises firewall shows that packets are received from the EC2 instance but responses are not reaching the instance. What is the most likely cause?

A financial services company runs a critical application on Amazon EC2 instances in a VPC. The application processes sensitive financial data and must meet strict compliance requirements. The security team recently discovered that an EC2 instance was compromised due to an unpatched vulnerability. The attacker used the instance's IAM role to access an S3 bucket containing customer data and exfiltrated the data. The security team needs to prevent such incidents in the future. They have implemented the following controls: - All EC2 instances are launched in private subnets. - The IAM roles used by EC2 instances follow the principle of least privilege. - Security groups restrict inbound and outbound traffic. - AWS Systems Manager Patch Manager is used to patch instances. - AWS CloudTrail is enabled and logs are sent to a centralized S3 bucket. - Amazon GuardDuty is enabled.
Despite these controls, the team is concerned about the blast radius if an instance is compromised again. Which additional measure would MOST effectively limit the blast radius of a compromised EC2 instance?

A company has a VPC with a public subnet and a private subnet. An EC2 instance in the private subnet needs to download patches from the internet. The instance is associated with a security group that allows outbound HTTPS (port 443) to 0.0.0.0/0. The private subnet route table has a default route (0.0.0.0/0) pointing to a NAT Gateway in the public subnet. The NAT Gateway's security group allows inbound HTTPS from the private subnet CIDR. However, the instance cannot download patches. What is the most likely cause?

A financial services company uses AWS KMS to encrypt sensitive data. The security team has a requirement to rotate the CMK every 90 days and to maintain a record of all previous key versions for decryption of historical data. The team creates a new CMK every 90 days and manually updates applications to use the new key. This process is error-prone and causes downtime. What is the MOST operationally efficient solution that meets the requirements?
Select an answer to reveal the explanation
A startup is building a web application on AWS and needs to protect sensitive customer data at rest in an Amazon RDS for MySQL database. The compliance team requires that the encryption keys be managed by the company's on-premises hardware security module (HSM) and be rotated every 6 months. Which solution should the startup use?

A healthcare company runs a HIPAA-compliant application on AWS. The application uses Amazon S3 to store Protected Health Information (PHI). The company has implemented the following controls: (1) All S3 buckets are configured with default encryption using SSE-S3. (2) Bucket policies restrict access to only authorized IAM roles. (3) S3 access logs are enabled and sent to a centralized logging account. (4) MFA Delete is enabled on all buckets. (5) Object lock is not enabled. Recently, an internal auditor discovered that when an authorized user deletes an object, the object is permanently deleted and cannot be recovered. The company's data retention policy requires that deleted PHI be recoverable for at least 30 days after deletion. A review of the IAM policies shows that users have s3:DeleteObject permission. The auditor also notes that the bucket versioning is not enabled. The security team needs to implement a solution that allows authorized users to delete objects but ensures that deleted objects can be recovered within 30 days. Which of the following is the MOST effective course of action?

Answer all 17 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing SCS-C02 on the first attempt. The most effective approach combines reading the official Amazon Web Services documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for SCS-C02 preparation:
Cover each SCS-C02 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing SCS-C02 score.
On exam day, the SCS-C02 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The SCS-C02 exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 750/1000 does not mean you need 75% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 750/1000 on the real exam.

Every question is written against the official SCS-C02 exam blueprint published by Amazon Web Services. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass SCS-C02 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The SCS-C02 covers 6 domains: Threat Detection and Incident Response (14%), Security Logging and Monitoring (18%), Identity and Access Management (16%), Management and Security Governance (14%), Infrastructure Security (20%), Data Protection (18%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Infrastructure Security and Security Logging and Monitoring — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Amazon Web Services's authorisation. Using them violates your NDA and Amazon Web Services's certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
