An Amazon DynamoDB table called SensorReadings captures sensor readings. These readings include a sensor ID attribute that acts as the partition key, and a timestamp attribute that is the sort key. Which statement is trup?

It is impossible for two items in the SensorReadings table to have the same primary key.

The sensor ID together with the timestamp represent a simple primary key.

It is impossible for two items in the SensorReadings table to have the same partition key.

It is impossible for two items in the SensorReadings table to have the same sort key.

Which statement about Amazon DynamoDB partitions is true?

If a table has a simple primary key (partition key only), DynamoDB stores and retrieves each item based on its hash attribute.

DynamoDB stores data in partitions and chooses the partition based on the range attribute.

If a table has a composite primary key, DynamoDB will sort the items based on the sort key before selecting the partition for the item.

A developer writes a hash function to tell DynamoDB how to partition the items.

Suppose that a developer has a restaurants database table that can be queried by name (the partition key), or by name and location (the sort key), What should the developer do if they also want to query by type of cuisine and average customer rating?

Set up a global secondary index on cuisine and customer rating.

Set up a local secondary index on cuisine and customer rating

Change the primary key on the restaurant table to be a complex primary key based on cuisine and customer rating.

Perform a query that uses the cuisine and average customer rating attributes.

Add an Amazon DynamoDB Accelerator (DAX) cluster

Create application code to check that all parts of the transaction were written successfully, and then roll back the update if any part failed.

Which scenarios are example use cases for Amazon DynamoDB Streams? (Select TWO.)

An application that automatically sends notifications to the mobile devices of all friends in a group when one friend uploads a new picture

An application that must monitor changes to a DynamoDB table and take action on specific changes when a value reaches a certain threshold

An application that requires repeated reads against a large set of regional weather data to perform a long-running analysis

An application that requires an in-memory data store

Which statement about global tables is true?

When a global table is created, Amazon DynamoDB performs all necessary tasks to create identical tables and propagate ongoing data changes to specified Regions.

Global tables provide a managed solution for replicating tables within a single AWS Region.

Global tables use Amazon Simple Storage Service (Amazon S3) to propagate changes between replicas.

With a global table. Amazon DynamoDB supports partial replication of some of the items in a tanle.

Which statement describes Amazon DynamoDB application programming interface (API) control operations that can be invoked by an application?

Create and manage DynamoDB tables.

A developer wants to use mock endpoints to test their API.

A developer wants to assign different API quotas by client.

Which statement about Amazon API Gateway integrations is true?

A developer can use HTTP proxy integrations to direct a route to a resource on the internet.

A first-class integration connects an API Gateway HTTP API route to an external third-party service API.

API Gateway cannot access resources within a virtual private cloud (VPC).

An API integration request encapsulates an HTTP request that the backend receives and is always different from the method request that the client submits.

An application that uses Amazon API Gateway must capture contact information from a third-party client application. The client application sends given name, surname, business phone, and cell phone. The harkend application database has only two fields: name and mobile phone. Which option requires the fewest application changes?

Use a mapping template to transform the request before it is sent to the database.

Export the API definition and use it to update the client.

Create a usage plan that describes the fields and applies only to this client

Use a first-class integration to connect the client to the database

Given this snippet: aws apigatewayv2 create-route\ --api-id 03z501670a \ --target arn:aws:lambda:us-east-2:AcctID:function.readFn Which option could replace the <?> to create an API route that returns an individual product value from an online catalog?

route-key 'GET /products/product_id}\

route-selection-expression '$GET/product'

route-selection-expression 'PUT/products/proxy+}\

Which statement about Amazon API Gateway stages is true?

What does the Amazon API Gateway integration Latency metric tell the user?

Frequency of server-side errors that affect latency

Speed of the API response back to the client

How often requests are throttled

Which statement describes a characteristic of AWS Lambda?

Lambda runs code only when it is activated by an event and uses only the compute resources that are needed.

A developer's methods and configuration options for ensuring high availability with Lambda are similar to their approach with Amazon Elastic Compute Cloud (Amazon EC2).

Lambda functions run in on-demand, temporary environments, and the developer controls when new environments are created or shut down.

A developer must write Lambda functions that use one of the runtimes that the Lambda service provides
