A business need a data warehouse system that stores data consistently and in a highly organized fashion. The organization demands rapid response times for end-user inquiries including current-year data, and users must have access to the whole 15-year dataset when necessary. Additionally, this solution must be able to manage a variable volume of incoming inquiries. Costs associated with storing the 100 TB of data must be maintained to a minimum.
Which solution satisfies these criteria?
Amazon RDS for Oracle with Transparent Data Encryption is used by a financial services organization (TDE). At all times, the organization is obligated to encrypt its data at rest. The decryption key must be widely distributed, and access to the key must be restricted. The organization must be able to rotate the encryption key on demand to comply with regulatory requirements. If any possible security vulnerabilities are discovered, the organization must be able to disable the key. Additionally, the company's overhead must be kept to a minimal.
What method should the database administrator use to configure the encryption to fulfill these specifications?
A company has a production environment running on Amazon RDS for SQL Server with an in-house web application as the front end. During the last application maintenance window, new functionality was added to the web application to enhance the reporting capabilities for management. Since the update, the application is slow to respond to some reporting queries.
How should the company identify the source of the problem?
An ecommerce company is running AWS Database Migration Service (AWS DMS) to replicate an on-premises Microsoft SQL Server database to Amazon RDS for SQL Server. The company has set up an AWS Direct Connect connection from its on-premises data center to AWS. During the migration, the company's security team receives an alarm that is related to the migration. The security team mandates that the DMS replication instance must not be accessible from public IP addresses.
What should a database specialist do to meet this requirement?
