AWS Certified Data Analytics – Specialty — Question 44

A company analyzes its data in an Amazon Redshift data warehouse, which currently has a cluster of three dense storage nodes. Due to a recent business acquisition, the company needs to load an additional 4 TB of user data into Amazon Redshift. The engineering team will combine all the user data and apply complex calculations that require I/O intensive resources. The company needs to adjust the cluster's capacity to support the change in analytical and storage requirements.
Which solution meets these requirements?

Answer options

• A. Resize the cluster using elastic resize with dense compute nodes.
• B. Resize the cluster using classic resize with dense compute nodes.
• C. Resize the cluster using elastic resize with dense storage nodes.
• D. Resize the cluster using classic resize with dense storage nodes.

Correct answer: B

Explanation

The correct answer is B because a classic resize allows for a more controlled and stable transition to dense compute nodes, which are better suited for I/O intensive tasks. Options A and C suggest elastic resizing, which can be faster but might not provide the necessary capacity for the complex calculations required. Option D is incorrect because it retains dense storage nodes, which are not optimal for the new requirements.
