Question No 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?

Choose the Choices:

The user name and password the application is using are incorrect.

The security group assigned to the application servers does not have the necessary rules to allow inbound connections from the DB instance.

The security group assigned to the DB instance does not have the necessary rules to allow inbound connections from the application servers.

The user name and password are correct, but the user is not authorized to use the DB instance.

Question No 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?

Choose the Choices:

After a database crash, Aurora needed to replay the redo log from the last database checkpoint

The client - side application is caching the DNS data and its TTL is set too high

After failover, the Aurora DB cluster needs time to warm up before accepting client connections

There were no active Aurora Replicas in the Aurora DB cluster

C
Question No 4

A company is deploying a solution in Amazon Aurora by migrating from an on - premises system. The IT department has established an AWS Direct Connect link from the company’s data center. The company’s Database Specialist has selected the option to require SSL/TLS for connectivity to prevent plaintext data from being set over the network. The migration appears to be working successfully, and the data can be queried from a desktop machine. Two Data Analysts have been asked to query and validate the data in the new Aurora DB cluster. Both Analysts are unable to connect to Auror a. Their user names and passwords have been verified as valid and the Database Specialist can connect to the DB cluster using their accounts. The Database Specialist also verified that the security group configuration allows network from all corporate IP addresses. What should the Database Specialist do to correct the Data Analysts’ inability to connect?

Choose the Choices:

Restart the DB cluster to apply the SSL change.

Instruct the Data Analysts to download the root certificate and use the SSL certificate on the connection string to connect.

Add explicit mappings between the Data Analysts’ IP addresses and the instance in the security group assigned to the DB cluster.

Modify the Data Analysts’ local client firewall to allow network traffic to AWS. Answer: D
Question No 5

A company is concerned about the cost of a large - scale, transactional application using Amazon DynamoDB that only needs to store data for 2 days before it is deleted. In looking at the tables, a Database Specialist notices that much of the data is months old, and goes back to when the application was first deployed. What can the Database Specialist do to reduce the overall cost?

Choose the Choices:

Create a new attribute in each table to track the expiration time and create an AWS Glue transformation to delete entries more than 2 days old.

Create a new attribute in each table to track the expiration time and enable DynamoDB Streams on each table.

Create a new attribute in each table to track the expiration time and enable time to live (TTL) on each table.

Create an Amazon CloudWatch Events event to export the data to Amazon S3 daily using AWS Data Pipeline and then truncate the Amazon DynamoDB table.
