AWS Solution Architect-Associate Exam Practice Questions (Free Quiz 3)

Your company wants you to create a lambda function to read data from Kinesis stream of transactions. You created this function using context logger in the code to log the data to CloudWatch so that it can be monitored later. After the function started running along with Kinesis stream, you did not see any log entries for the new lambda function. What could be the reason?

To launch an operation, your organization requires you to create a REST API. You are going to create this API using AWS API gateway with lambda as backend system and Oracle RDS instance as database. You have created API methods, lambda function code and launched the Oracle RDS instance in a private VPC which does not have an internet gateway. However, connection getting failed when you are trying to connect to RDS from your lambda function. Why? (Choose 2 reasons)

A team of data analysts need you. They need to perform big data analysis to transform data and store the results in S3.

How will you do this?

You are required to upload large files (1 GB – 3 GB) to S3 and calculate the hash checksum of the file to identify any potential corruption in downloads. This can be done by reading the entre file.

Company PQRS, uploads compressed files to S3. These files are relatively large (100-200 MB). When upload completes, the total number of objects in the compressed files is added as the metadata of the file. They have hired you for a cost effective solution for this scenario. You recommended that they should use AWS lambda with S3 event notifications. For that, they are concerned about failures. S3 event notification is an asynchronous one-time trigger and lambda can fail due to operation timeouts, max memory limits, ma execution time limits etc. What could be the best retry approach?
