Question 80

A global digital advertising company captures browsing metadata to contextually display relevant images, pages, and links to targeted users. A single page load can generate multiple events that need to be stored individually. The maximum size of an event is 200 KB and the average size is 10 KB. Each page load must query the user’s browsing history to provide targeting recommendations. The advertising company expects over 1 billion page visits per day from users in the United States, Europe, Hong Kong, and India. The structure of the metadata varies depending on the event. Additionally, the browsing metadata must be written and read with very low latency to ensure a good viewing experience for the users.

Which database solution meets these requirements?

Options:

Amazon DocumentDB

Amazon RDS Multi-AZ deployment

Amazon DynamoDB global table

Amazon Aurora Global Database

Question 81

A company runs online transaction processing (OLTP) workloads on an Amazon RDS for PostgreSQL Multi- AZ DB instance. Tests were run on the database after work hours, which generated additional database logs. The free storage of the RDS DB instance is low due to these additional logs.

What should the company do to address this space constraint issue?

Options:

Modify the rds.log_retention_period parameter to 1440 and wait up to 24 hours for database logs to be deleted

Create a ticket with AWS Support to have the logs deleted

Run the SELECT rds_rotate_error_log() stored procedure to rotate the logs

Question 82

A company conducted a security audit of its AWS infrastructure. The audit identified that data was not encrypted in transit between application servers and a

MySQL database that is hosted in Amazon RDS.

After the audit, the company updated the application to use an encrypted connection. To prevent this problem from occurring again, the company's database team needs to configure the database to require in-transit encryption for all connections.

Which solution will meet this requirement?

Options:

Update the parameter group in use by the DB instance, and set the require_secure_transport parameter to ON.

Connect to the database, and use ALTER USER to enable the REQUIRE SSL option on the database user.

Update the security group in use by the DB instance, and remove port 80 to prevent unencrypted connections from being established.

Update the DB instance, and enable the Require Transport Layer Security option.

What should a Database Specialist do to copy the database backup into a different Region?

Options:

Use Amazon RDS automated snapshots and use AWS Lambda to copy the snapshot into another Region

Create an AWS Lambda function to take an Amazon RDS snapshot every 6 hours and use a second Lambda function to copy the snapshot into another Region

Create a cross-Region read replica for Amazon RDS in another Region and take an automated snapshot of the read replica
