20+ practice questions focused on Cloud Concepts — one of the most tested topics on the AWS Certified Cloud Practitioner CLF-C02 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cloud Concepts PracticeA company runs a critical e-commerce application on Amazon EC2 instances distributed across multiple Availability Zones in a single AWS Region. The application is designed so that if an entire Availability Zone experiences an outage, the application continues to serve traffic from the remaining Availability Zones without interruption. Which benefit or characteristic of cloud computing does this scenario BEST represent?
Explanation: The scenario describes an application that continues to operate without interruption when an entire Availability Zone fails. This is the definition of fault tolerance, which refers to a system's ability to remain fully operational with no downtime even when components fail. While high availability also uses redundancy across multiple Availability Zones, it typically allows for minimal downtime during failover. Fault tolerance goes further by eliminating any interruption, making it the best fit for the 'without interruption' condition described.
A company's application runs on multiple AWS services across different geographic regions. The development team needs to access and manage these resources from their office using standard web browsers and API calls over the internet. The team does not need any dedicated private network connections. Which essential characteristic of cloud computing does this scenario best demonstrate?
Explanation: Broad network access is the correct answer because the scenario describes accessing AWS resources over the internet using standard web browsers and API calls, without requiring dedicated private network connections. This characteristic ensures that cloud services are available from any standard device (e.g., laptops, smartphones) using standard protocols such as HTTPS (port 443) and RESTful APIs, which is exactly what the development team needs.
According to the AWS Well-Architected Framework, which design principle is most closely associated with the recommendation to 'stop spending money on undifferentiated heavy lifting'?
Explanation: The AWS Well-Architected Framework's principle of 'stop spending money on undifferentiated heavy lifting' is part of the Cost Optimization pillar. It directly advocates for using managed services to offload operational tasks like patching, scaling, and hardware maintenance. By leveraging services such as Amazon RDS (instead of self-managed databases) or AWS Lambda (instead of managing servers), you reduce the operational burden and focus on business differentiation. This aligns with the Cost Optimization pillar's goal of focusing spending on business value rather than undifferentiated activities.
Drag and drop the steps to create an IAM user with programmatic access and attach a policy in the correct order.
Explanation: The correct sequence is: Step 1: Create the IAM user. Step 2: Attach a policy to the user to grant permissions. Step 3: Enable programmatic access (generate access keys). Step 4: Securely store the access key ID and secret access key. This matches option C. In the AWS IAM console, when creating a user, you select programmatic access, attach policies, and then the access keys are generated upon final creation. Generating keys before attaching a policy (as in option A) does not follow the standard best-practice order.
Drag and drop the steps to troubleshoot an EC2 instance that is not reachable via SSH in the correct order.
Explanation: The correct order starts with verifying the instance has a public IP, as without it no external connectivity is possible. Next, check security group inbound rules for SSH (port 22) because security groups act as a virtual firewall at the instance level. Then, check network ACLs for inbound and outbound rules, as NACLs provide stateless filtering at the subnet level. Finally, ensure the route table has a route to an internet gateway, allowing traffic to leave the subnet.
