A company has a production Amazon Aurora Db cluster that serves both online transaction processing (OLTP)
transactions and compute-intensive reports. The reports run for 10% of the total cluster uptime while the OLTP
transactions run all
the time. The company has benchmarked its workload and determined that a six-node Aurora DB cluster is appropriate
for the peak workload. The company is now looking at cutting costs for this DB cluster but needs to have a sufficient
number of nodes in the cluster to support the workload at different times. The workload has not changed since the
previous benchmarking exercise.
How can a Database Specialist address these requirements with minimal user involvement?
A. Split up the DB cluster into two different clusters: one for OLTP and the other for reporting. Monitor and set up
replication between the two clusters to keep data consistent.
B. Review all evaluates the peak combined workload. Ensure that utilization of the DB cluster node is at an acceptable
level. Adjust the number of instances, if necessary.
C. Use the stop cluster functionality to stop all the nodes of the DB cluster during times of minimal workload. The cluster
can be restarted again depending on the workload at the time.
D. Set up automatic scaling on the DB cluster. This will allow the number of reader nodes to adjust automatically to the
reporting workload, when needed.
Correct Answer: D
A company is using Amazon with Aurora Replicas for read-only workload scaling. A Database Specialist needs
to split up two read-only applications so each application always connects to a dedicated replica. The Database Specialist wants to implement load balancing and high availability for the read-only applications.
Which solution meets these requirements?
A. Use a specific instance endpoint for each replica and add the instance endpoint to each read-only application
B. Use reader endpoints for both the read-only workload applications.
C. Use a reader endpoint for one read-only application and use an instance endpoint for the other read-only application.
D. Use custom endpoints for the two read-only applications.
Correct Answer: B
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- east1.rds.amazonaws.com endpoint
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
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?
