The company\u2019s website is hosted on AWS and backed by an Amazon RDS for PostgreSQL DB instance. The website explains the promotion and includes a sign-up page that collects user information and preferences. Management expects large and unpredictable volumes of traffic periodically, which will create many database writes. A solutions architect needs to build a solution that does not change the underlying data model and ensures that submissions are not dropped before they are committed to the database.<br \/>\nWhich solution meets these requirements? <br \/><strong><br \/>A.<\/strong> Immediately before the event, scale up the existing DB instance to meet the anticipated demand. Then scale down after the event. <br \/><strong>B.<\/strong> Use Amazon SQS to decouple the application and database layers. Configure an AWS Lambda function to write items from the queue into the database. <br \/><strong>C.<\/strong> Migrate to Amazon DynamoDB and manage throughput capacity with automatic scaling. <br \/><strong>D.<\/strong> Use Amazon ElastiCache for Memcached to increase write capacity to the DB instance.<\/div>\n<p><\/p>\n<style> .hidden-div{ display:none } <\/style>\n<p>\t\t\t\t\t\t\t<button onclick=\"getElementById('hidden-div').style.display = 'block'\"> Show Answer <\/button> <button onclick=\"getElementById('hidden-div').style.display = 'none'\">Hide Answer<\/button><\/p>\n<div class=\"hidden-div\" id=\"hidden-div\"><span style=\"\"><\/p>\n<div class=\"answer\">Correct Answer: <strong>D<\/strong><\/div>\n<p><strong>Explanation:<\/strong> <\/p>\n<div class=\"explanation\">\nReference: <a href=\"https:\/\/aws.amazon.com\/elasticache\/faqs\/\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/aws.amazon.com\/elasticache\/faqs\/<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>A company is planning a large event where a promotional offer will be introduced.
