Question
A company hosts a continuous integration and continuous delivery (CI/CD) environment on AWS. The CI/CD environment includes a Jenkins server that is hosted on an Amazon EC2 instance. A 500 GB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume is attached to the EC2 instance. Because of disk throughput limitations, the Jenkins server reports performance issues that are resulting in slower builds on the server. The EBS volume needs to sustain 3,000 IOPS while performing nightly build tasks. A SysOps administrator examines the server's history in Amazon CloudWatch. The BurstBalance metric has had a value of 0 during nightly builds. The SysOps administrator needs to improve the performance and meet the sustained throughput requirements. Which solution will meet these requirements MOST cost-effectively?
Options
- ADouble the gp2 EBS volume size from 500 GB to 1,000 GB.
- BChange the volume type from gp2 to General Purpose SSD (gp3).
- CChange the volume type from gp2 to Throughput Optimized HDD (st1).
- DChange the volume type from gp2 to Provisioned IOPS SSD (io2).

Explanation
The gp3 volume type is designed to provide baseline performance of 3,000 IOPS and a throughput of up to 125 MB/s. This aligns with the requirement to sustain 3,000 IOPS during nightly build tasks. gp3 volumes are a good fit for a wide range of transactional workloads and offer a more cost- effective solution compared to Provisioned IOPS SSD (io2) volumes.
