Sample questions

A company wants to commit to a consistent amount of compute usage (measured in $/hour) across any instance family, size, OS, or region. Which pricing model provides the highest flexibility while still offering a discount over On-Demand?

Standard Reserved Instances
EC2 Instance Savings Plans
Spot Instance blocks
Convertible Reserved Instances
Compute Savings Plans

An Auto Scaling Group lifecycle hook is in the 'Pending:Wait' state. The hook's heartbeat timeout expires before the custom action completes. What happens by default?

The ASG sends an SNS alert and waits for operator approval
The instance stays in 'Pending:Wait' indefinitely until manually resolved
The instance moves to 'Pending:Proceed' and continues launching
The instance is marked unhealthy and replaced after two health-check failures
The instance is immediately terminated and replaced

What is the primary cause of a Lambda 'cold start', and which runtime typically has the lowest cold-start latency?

Cold starts occur when a new execution environment is initialized; compiled runtimes like Rust or Go typically have lower cold-start latency than JVM-based ones
Cold starts happen when the function code exceeds 50 MB; Java has the lowest latency due to JIT
Cold starts occur only when memory is set below 512 MB; increasing memory eliminates them
Cold starts are triggered by VPC attachment; disabling VPC eliminates cold starts entirely
Cold starts are caused by Lambda throttling; Python always has the lowest latency

Lambda SnapStart is currently supported for which runtime, and what does it snapshot?

Java (Corretto 11/17/21); it snapshots the initialized execution environment after the init phase
Go 1.x; it snapshots the compiled binary and linked libraries at deploy time
All runtimes with ARM64 architecture; it snapshots the function's memory state mid-execution
Python 3.12; it snapshots the function's /tmp storage and environment variables
Node.js 20; it snapshots the event payload and function code package

AWS App Runner automatically scales containers based on incoming requests. Which source types can App Runner use to build and deploy an application?
