A company has deployed an application that uses an Amazon RDS for MySQL DB cluster. The DB cluster uses three read replicas. The primary DB instance is an
8XL-sized instance, and the read replicas are each XL-sized instances.
Users report that database queries are returning stale dat
a. The replication lag indicates that the replicas are 5 minutes behind the primary DB instance. Status queries on the replicas show that the SQL_THREAD is 10 binlogs behind the IO_THREAD and that the IO_THREAD is 1 binlog behind the primary.
Which changes will reduce the lag? (Choose two.)
- A. Migrate the primary DB instance to an Amazon Aurora MySQL DB cluster and add three Aurora Replicas.
- B. Increase the instance size of the read replicas to the same size and class as the primary DB instance.
- C. Move the read replicas to the same Availability Zone as the primary DB instance.
- D. Deploy two additional read replicas matching the existing replica DB instance size.
- E. Increase the instance size of the primary DB instance within the same instance class.
Answer: A,B

NEW QUESTION 54
An Amazon RDS EBS-optimized instance with Provisioned IOPS (PIOPS) storage is using less than half of its allocated IOPS over the course of several hours under constant load. The RDS instance exhibits multi-second read and write latency, and uses all of its maximum bandwidth for read throughput, yet the instance uses less than half of its CPU and RAM resources.
What should a Database Specialist do in this situation to increase performance and return latency to sub-second levels?
- A. Increase the size of the DB instance storage
- B. Disable EBS optimization on the DB instance
- C. Change the underlying EBS storage type to General Purpose SSD (gp2)
- D. Change the DB instance to an instance class with a higher maximum bandwidth
Answer: C
NEW QUESTION 55
A company has migrated a single MySQL database to Amazon Auror
a. The production data is hosted in a DB cluster in VPC_PROD, and 12 testing environments are hosted in VPC_TEST using the same AWS account. Testing results in minimal changes to the test data. The Development team wants each environment refreshed nightly so each test database contains fresh production data every day.
Which migration approach will be the fastest and most cost-effective to implement?
- A. Run the master in Amazon Aurora MySQL. Create 12 Aurora Replicas in VPC_TEST, and script the replicas to be deleted and re-created nightly.
- B. Run the master in Amazon Aurora MySQL using Aurora Serverless. Create 12 clones in VPC_TEST, and script the clones to be deleted and re-created nightly.
- C. Run the master in Amazon Aurora MySQL. Take a nightly snapshot, and restore it into 12 databases in VPC_TEST using Aurora Serverless.
- D. Run the master in Amazon Aurora MySQL. Create 12 clones in VPC_TEST, and script the clones to be deleted and re-created nightly.
Answer: D
NEW QUESTION 56
A large retail company recently migrated its three-tier ecommerce applications to AWS. The company's backend database is hosted on Amazon Aurora PostgreSQL. During peak times, users complain about longer page load times. A database specialist reviewed Amazon RDS Performance Insights and found a spike in IO:XactSync wait events. The SQL attached to the wait events are all single INSERT statements.
How should this issue be resolved?
- A. Add an Amazon ElastiCache for Redis cluster and change the application to write through.
- B. Change the Aurora DB cluster storage to Provisioned IOPS (PIOPS).
- C. Modify the application to commit transactions in batches
- D. Add a new Aurora Replica to the Aurora DB cluster.
Answer: C
Explanation:
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraPostgreSQL.Reference.html
"This wait most often arises when there is a very high rate of commit activity on the system. You can sometimes alleviate this wait by modifying applications to commit transactions in batches. "
