An online bookstore uses Amazon Aurora MySQL as its backend database. After the online bookstore added a popular book to the online catalog, customers began reporting intermittent timeouts on the checkout page. A database specialist determined that increased load was causing locking contention on the database. The database specialist wants to automatically detect and diagnose database performance issues and to resolve bottlenecks faster.
Which solution will meet these requirements?
A company is using Amazon Redshift. A database specialist needs to allow an existing Redshift cluster to access data from other Redshift clusters. Amazon RDS for PostgreSQL databases, and AWS Glue Data Catalog tables.
Which combination of steps will meet these requirements with the MOST operational efficiency? (Choose three.)
A database specialist is launching a test graph database using Amazon Neptune for the first time. The database specialist needs to insert millions of rows of test observations from a .csv file that is stored in Amazon S3. The database specialist has been using a series of API calls to upload the data to the Neptune DB instance.
Which combination of steps would allow the database specialist to upload the data faster? (Choose three.)
A company needs to deploy an Amazon Aurora PostgreSQL DB instance into multiple accounts. The company will initiate each DB instance from an existing Aurora PostgreSQL DB instance that runs in a shared account. The company wants the process to be repeatable in case the company adds additional accounts in the future. The company also wants to be able to verify if manual changes have been made to the DB instance configurations after the company deploys the DB instances.
A database specialist has determined that the company needs to create an AWS CloudFormation template with the necessary configuration to create a DB instance in an account by using a snapshot of the existing DB instance to initialize the DB instance. The company will also use the CloudFormation template's parameters to provide key values for the DB instance creation (account ID, etc.).
Which final step will meet these requirements in the MOST operationally efficient way?
A company uses an Amazon RDS for PostgreSQL database in the us-east-2 Region. The company wants to have a copy of the database available in the us-west-2 Region as part of a new disaster recovery strategy.
A database architect needs to create the new database. There can be little to no downtime to the source database. The database architect has decided to use AWS Database Migration Service (AWS DMS) to replicate the database across Regions. The database architect will use full load mode and then will switch to change data capture (CDC) mode.
Which parameters must the database architect configure to support CDC mode for the RDS for PostgreSQL database? (Choose three.)
