AWS Certified SysOps Administrator – Associate (legacy) — Question 90

The amount of data a company must back up has been increasing, and storage space is quickly running out. There is no budget to purchase new backup software that is capable of backing up data directly to the cloud.
What is the MOST cost-effective way to make storage available to the company's legacy backup system?

Answer options

• A. Launch an Amazon EC2 instance, add large Amazon EBS volumes, and connect using VPN
• B. Ship backup tapes to AWS for storage in secure AWS Availability Zones
• C. Use AWS Snowball on a weekly basis to transfer data to Amazon Glacier
• D. Use AWS Storage Gateway to present a VTL using iSCSI to the legacy application

Correct answer: C

Explanation

The correct answer is C because using AWS Snowball allows for efficient and cost-effective transfer of large amounts of data to Amazon Glacier for archiving. Options A and D involve more complex setups that may incur higher costs and require additional resources, while option B is less efficient and slower compared to the automated transfer capabilities of AWS Snowball.
