A company is running a popular social media site on EC2 instances. The application stores data in an Amazon RDS for MySQL DB instance and has implemented read caching by using an ElastiCache for Redis (cluster mode enabled) cluster to improve read times. A social event is happening over the weekend, and the SysOps Administrator expects website traffic to triple.
What can a SysOps Administrator do to ensure improved read times for users during the social event?

A. Use Amazon RDS Multi-AZ.
B. Add shards to the existing Redis cluster.
C. Offload static data to Amazon S3.
D. Launch a second Multi-AZ Redis cluster.
