Free Assessment: AWS Certified Solutions Architect Associate Practice Questions – Part 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. They were doing this with a lambda function.
But, sometimes, the execution gets terminated abruptly after 5 minutes. They are asking
you to enable notifications for such termination situations. 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. Against these requirements, you created a lambda function
with S3 notifications to trigger it. When you tested your function, the request is getting
timed out. Why?

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?

An organization is planning to move its on premise infrastructure to the AWS cloud
and is in need to migrate the virtual machines. You have been approached for
