Compute Quiz

Select one answer per question. You will receive immediate feedback.

1. A developer creates a custom AMI in us-east-1 and wants to launch EC2 instances from it in eu-west-1. What must they do first?

Download the AMI to their local machine and re-uploadCopy the AMI to eu-west-1Create a new AMI from scratch in eu-west-1Use the same AMI — it works globally

2. A startup runs a steady-state web application 24/7 and wants to minimize compute costs over the next year. Which EC2 purchasing option is most cost-effective?

Spot InstancesReserved InstancesOn-Demand InstancesDedicated Hosts

3. A team needs to run an in-memory database that requires large amounts of RAM. Which EC2 instance family should they choose?

C familyT familyM familyR family

4. A company builds a video rendering pipeline that requires GPU processing. Which EC2 instance family is designed for GPU-accelerated workloads?

R familyM familyG familyC family

5. A workload requires a background process to run continuously for 45 minutes. Which AWS compute service is most appropriate?

AWS LambdaAmazon EC2AWS FargateAWS Elastic Beanstalk

6. A company currently runs Kubernetes on-premises and wants to migrate to AWS without changing their container orchestration tooling. Which service should they use?

Amazon ECSAWS LambdaAmazon EKSAWS Elastic Beanstalk

7. A team wants to run Docker containers in production but does not want to provision or manage the underlying EC2 instances. Which option meets this requirement?

Amazon ECS with Fargate launch typeAmazon ECS with EC2 launch typeAmazon EKS with managed node groupsAmazon EC2 with user data scripts

8. A developer wants to deploy a Python web application by uploading code and having AWS handle provisioning, load balancing, and automatic scaling. Which service is the best fit?

Amazon EC2AWS LambdaAmazon EKSAWS Elastic Beanstalk

9. What is the key difference between a container and a virtual machine?

Containers are slower to start than virtual machinesContainers share the host OS kernel; VMs each have their own guest OSVMs are smaller and more portable than containersContainers require a hypervisor to run

10. A company runs distributed data processing jobs that can tolerate interruptions and can be restarted. They want the lowest possible EC2 cost. Which purchasing option should they use?

On-Demand InstancesReserved InstancesSpot InstancesDedicated Instances

11. A developer writes a data transformation function that takes 25 minutes to complete per invocation. Can they run this on AWS Lambda?

Yes, Lambda supports up to 60 minutesNo, Lambda has a maximum timeout of 15 minutesYes, if they increase the memory allocationNo, Lambda functions cannot run longer than 1 second

12. A startup launches a new application and is unsure what the traffic pattern will be. They want maximum flexibility with no upfront commitment. Which EC2 pricing option is best?

Spot InstancesReserved InstancesOn-Demand InstancesDedicated Hosts

13. A company runs a small web server with low baseline CPU usage that occasionally bursts to handle peak traffic. Which EC2 instance family is purpose-built for burstable performance?

C familyM familyR familyT family

14. A company has software licenses tied to physical CPU sockets and requires visibility into the underlying hardware. Which EC2 purchasing option meets this requirement?

On-Demand InstancesReserved InstancesSpot InstancesDedicated Hosts

15. When you launch a Linux EC2 instance and create a new key pair, how many chances do you have to download the private key file?

Unlimited — you can download it anytime from the EC2 consoleOne — AWS does not keep a copy of the private keyTwo — once at launch and once from the IAM dashboardNone — AWS stores the private key and applies it automatically

16. A developer passes a script to an EC2 instance that installs software and applies patches on first boot. What is this script called?

Instance metadataUser dataLaunch configurationCloudFormation template

17. A developer stops an EBS-backed EC2 instance to avoid weekend charges. When they start it on Monday, what is true?

The instance resumes on the same host with all data intactThe instance moves to a new host; EBS data persists, but instance store data is lostThe instance is permanently terminated and must be recreatedThe instance remains in pending state for 24 hours

18. A company tags every EC2 instance with "Department" and "Project" keys. What is the primary exam-relevant benefit of this?

Tags automatically reduce EC2 costs by allocating reserved capacityTags enable cost allocation reports to track spending by department or projectTags replace the need for security groups by controlling network accessTags encrypt the instance metadata to prevent unauthorized access

19. A company uses m5.xlarge instances 24/7 with only 15% average CPU utilization. Which pillar of cost optimization should they apply first?

Increase elasticity — add Auto ScalingRight size — downsize to a smaller instance typeOptimal pricing model — switch to Reserved InstancesOptimize storage choices — switch from EBS to Instance Store

20. A company wants to stop their development EC2 instances every night and restart them in the morning. What pillar of cost optimization and approach represents this?

Right size — choose smaller instance typesIncrease elasticity — use resources only when neededOptimal pricing model — switch to Spot InstancesOptimize storage choices — use S3 instead of EBS

Progress: 0/20 correct (0%). Answer all questions to see the final recommendation.

Ask your teacher: Scoring: 17/20 (85%) or higher = move on to Storage. 14-16/20 (70-80%) = review missed topics. 13/20 or below = revisit the relevant lessons before continuing.
