AWS Lambda Functions Quiz
Test your knowledge of AWS Lambda fun
You'll encounter questions on:
- Memory capacities
- Concurrent executions
- Cold start problems
- Performance optimization
What is the maximum memory capacity you can allocate to the AWS Lambda functions?
1024MB
3008MB
2048MB
10240MB
What is the minimum memory capacity you can allocate to the AWS Lambda function?
64MB
108MB
128MB
256MB
What is the default quota for concurrent Lambda executions?
500
1000
3000
10000
Can you increase this quota?
Yes
No
How to describe Lambda cold start problem?
It happens when Lambda reuses existing container and wait till the previous execution is completed
It happens when you execute an inactive function
This is the overhead in starting a Lambda invocation
It happens when Lambda code is downloaded from S3 bucket in different region than the execution
When cold start problem is usually visible?
After a fresh deployment
When there are no request to a given Lambda for some time
When data in the Lambda request has changed
All of the above
What has an impact on Lambda execution time?
Programming language
Memory allocation
Package/code size
All of the above
What lifecycle phases contribute to the cold start problem?
Starting your code
Starting new container
Bootstraping the runtime
Downloading your code
How to prove that the Lambda reuses existing container?
There are Lambda metrics that show how many times new container was created vs. Existing container was reused
Create a static variable, increment and log it in the handler method
Lambda logs contain execution parameters, including information if container was reused or not
Save some file in /tmp directory if it doesn't exist or log the file content otherwise
What programming language would you choose to avoid cold start problem?
#C
Ruby
Java
NodeJS
