A Developer has created an Amazon Cognito user pool and configured a domain for it. The Developer wants to add sign-up and sign-in pages to an app with a company logo.
What should the Developer do to meet these requirements?
A developer is creating an application that uses an AWS Lambda function to transform and load data from an
Amazon S3 bucket. When the developer tests the application, the developer finds that some invocations of the
Lambda function are slower than others.

latency. Any initialization activities, such as loading libraries and instantiating clients, must run during
allocation time rather than during actual function invocations.
Which combination of steps will meet these requirements? (Select TWO.)
