A company is planning on using Kinesis Firehose to stream data to an AWS Redshift cluster. The cluster will be hosted in a VPC. Which of the following is required to ensure the data can be sent over from Kinesis to AWS Redshift? Choose 2 answers from the options given below.

Answer options:

A.Ensure that the Kinesis Stream unblocks the ingress traffic from the AWS Redshift cluster
B.Ensure that the AWS Redshift cluster unblocks the ingress traffic from the AWS Kinesis stream
C.Ensure that the Redshift cluster is provided with a private IP
D.Ensure that the Redshift cluster is provided with a public IP

Answer – B and D
The AWS Documentation mentions the following
If your Amazon Redshift cluster is in a virtual private cloud (VPC), it must be publicly accessible with a public IP address. Also, grant Kinesis Data Firehose access to your Amazon Redshift cluster by unblocking the Kinesis Data Firehose IP addresses.
Since this is clearly mentioned in the AWS Documentation, all other options are incorrect
