Demo Questions

Question 1
A company has deployed an e-commerce web application in a new AWS account. An Amazon RDS for MySQL Multi-AZ DB instance is part of this deployment with a database-1.xxxxxxxxxxxx.us-east-1.rds.amazonaws.com endpoint listening on port 3306. The company's Database Specialist is able to log in to MySQL and run queries from the bastion host using these details. When users try to utilize the application hosted in the AWS account, they are presented with a generic error message. The application servers are logging a 'could not connect to server: Connection times out' error message to Amazon CloudWatch Logs. What is the cause of this error?
  1. The user name and password the application is using are incorrect.
  2. The security group assigned to the application servers does not have the necessary rules to allow inbound connections from the DB instance.
  3. The security group assigned to the DB instance does not have the necessary rules to allow inbound connections from the application servers.
  4. The user name and password are correct, but the user is not authorized to use the DB instance.
Correct answer: C
Question 2
An AWS CloudFormation stack that included an Amazon RDS DB instance was accidentally deleted and recent data was lost. A Database Specialist needs to add RDS settings to the CloudFormation template to reduce the chance of accidental instance data loss in the future. Which settings will meet this requirement? (Choose three.)
  1. Set DeletionProtection to True.
  2. Set MultiAZ to True.
  3. Set TerminationProtection to True.
  4. Set DeleteAutomatedBackups to False.
  5. Set DeletionPolicy to Delete.
  6. Set DeletionPolicy to Retain.
Correct answer: ADF
Question 3
A Database Specialist is troubleshooting an application connection failure on an Amazon Aurora DB cluster with multiple Aurora Replicas that had been running with no issues for the past 2 months. The connection failure lasted for 5 minutes and corrected itself after that. The Database Specialist reviewed the Amazon RDS events and determined a failover event occurred at that time. The failover process took around 15 seconds to complete. What is the MOST likely cause of the 5-minute connection outage?
  1. After a database crash, Aurora needed to replay the redo log from the last database checkpoint.
  2. The client-side application is caching the DNS data and its TTL is set too high.
  3. After failover, the Aurora DB cluster needs time to warm up before accepting client connections.
  4. There were no active Aurora Replicas in the Aurora DB cluster.
Correct answer: B
