Simulate the real AWS Certified Security Specialty SCS-C02 exam with full-length timed sessions. Questions drawn proportionally from all 6 official blueprint domains — the same mix you'll face on test day.
Simulate real exam conditions
For the most realistic SCS-C02 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (170 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free SCS-C02 mock exam uses the same question distribution as the real AWS Certified Security Specialty SCS-C02 exam. Each session draws questions proportionally from all 6 official blueprint domains published by Amazon Web Services, so the topic mix you see accurately reflects what you'll face on test day.
SCS-C02 Domain Distribution
Threat Detection and Incident Response
Security Logging and Monitoring
Identity and Access Management
Management and Security Governance
Infrastructure Security
Data Protection
Every question is written by certified engineers against the 2026 SCS-C02 exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your SCS-C02 study plan.
Practice test — for learning
Use the SCS-C02 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the SCS-C02 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

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?

Answer all 13 questions to see your domain score breakdown
Sitting the SCS-C02 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The SCS-C02 exam lasts 170 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most SCS-C02 distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Amazon Web Services writes many SCS-C02 questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real SCS-C02 is a mental marathon lasting 170 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 170 minutes in practice, you will struggle on exam day.

Scaled scoring
The SCS-C02 uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 750/1000 threshold, giving you a buffer for any unexpected question types on the real exam.
Yes. Courseiva provides free SCS-C02 mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores of 80% or above on full-length SCS-C02 mock exams before booking your test date. The official passing score of 750/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for difficulty variation and question styles on the real exam.
Most candidates who pass SCS-C02 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
