AWS Certified Solutions Architect – Professional — Question 555

You want to use Amazon Redshift and you are planning to deploy dw1.8xlarge nodes. What is the minimum amount of nodes that you need to deploy with this kind of configuration?

Answer options

• A. 1
• B. 4
• C. 3
• D. 2

Correct answer: D

Explanation

When deploying Amazon Redshift with dw1.8xlarge nodes, a minimum of two nodes is required because this node type does not support a single-node cluster configuration. If you require a single-node setup, you must use a smaller node type such as dw1.xlarge. Therefore, a minimum of 2 nodes is necessary for dw1.8xlarge clusters.
