DynamoDB - Cost Optimization and Monitoring

AUse a single-node DAX cluster and disable caching to reduce complexity.

BUse a DAX cluster with multiple nodes to handle high read traffic and enable caching.

CAvoid using DAX and rely only on DynamoDB for all reads and writes.

DUse DAX only for write operations to speed up data insertion.

Step-by-Step Solution

Solution:

Step 1: Understand DAX use case
DAX is best for many users reading the same data often, improving read speed.
Step 2: Choose cluster setup
Multiple nodes improve availability and handle high read traffic efficiently.
Step 3: Evaluate options
Use a DAX cluster with multiple nodes to handle high read traffic and enable caching. matches best practice: multi-node cluster with caching enabled.
Final Answer:
Use a DAX cluster with multiple nodes to handle high read traffic and enable caching. -> Option B
Quick Check:
Multi-node DAX cluster for heavy reads = A [OK]

Quick Trick: Multi-node DAX clusters handle many reads efficiently [OK]
