Front
A company needs to run a batch processing job that can be interrupted. Which EC2 instance type minimizes cost?
Back
Spot Instances
Ideal for fault-tolerant applications as they utilize spare AWS capacity at steep discounts.
Front
What is the primary difference between EBS and Instance Store?
Back
Persistence
EBS is network-attached and persists after stop/termination; Instance Store is physically attached and ephemeral (data lost on stop).
Front
Which EC2 Placement Group should be used to minimize network latency between instances?
Back
Cluster Placement Group
Packs instances close together inside a single Availability Zone to achieve low-latency network throughput.
Front
How can you securely retrieve database credentials within an EC2 instance without hardcoding them?
Back
IAM Roles and Instance Profiles
Assign a role to the EC2 instance to grant temporary permissions to access Secrets Manager or Parameter Store.
Front
What feature allows an EC2 instance to save its RAM state to EBS and resume quickly later?
Back
EC2 Hibernate
The contents from the RAM are persisted to the EBS root volume; the instance boots faster than a cold start.
Front
Which EBS volume type is designed for high-performance database workloads requiring over 16,000 IOPS?
Back
Provisioned IOPS SSD (io1/io2)
Designed for I/O-intensive workloads that require sustained IOPS performance and low latency.
Front
What is the purpose of an Auto Scaling Group (ASG) Cooldown Period?
Back
To prevent over-scaling
Ensures the ASG does not launch or terminate additional instances before the previous scaling activity takes effect.
Front
Which tool provides a way to automate the creation, management, and distribution of server images (AMIs)?
Back
EC2 Image Builder
Simplifies the building, testing, and deployment of virtual machine and container images.
