A company has a hybrid environment in which a VPC connects to an on-premises network through an
AWS Site-to-Site VPN connection. The VPC contains an application that is hosted on Amazon EC2
instances. The EC2 instances run in private subnets behind an Application Load Balancer (ALB) that is
associated with multiple public subnets. The EC2 instances need to securely access an Amazon
DynamoDB table.
Which solution will meet these requirements?
A Database Specialist migrated an existing production MySQL database from on-premises to an
Amazon RDS for MySQL DB instance. However, after the migration, the database needed to be
encrypted at rest using AWS KMS. Due to the size of the database, reloading, the data into an
encrypted database would be too time- consuming, so it is not an option.
How should the Database Specialist satisfy this new requirement?
A media company is using Amazon RDS for PostgreSQL to store user dat
a. The RDS DB instance currently has a publicly accessible setting enabled and is hosted in a public
subnet. Following a recent AWS Well- Architected Framework review, a Database Specialist was given
new security requirements.
Only certain on-premises corporate network IPs should connect to the DB instance. Connectivity is
allowed from the corporate network only.
Which combination of steps does the Database Specialist need to take to meet these new
requirements? (Choose three.)
A Database Specialist is working with a company to launch a new website built on Amazon Aurora
with several Aurora Replicas. This new website will replace an on-premises website connected to a
legacy relational database. Due to stability issues in the legacy database, the company would like to
test the resiliency of Aurora.
Which action can the Database Specialist take to test the resiliency of the Aurora DB cluster?
A company has a database monitoring solution that uses Amazon CloudWatch for its Amazon RDS for
SQL Server environment. The cause of a recent spike in CPU utilization was not determined using the
standard metrics that were collected. The CPU spike caused the application to perform poorly,
impacting users. A Database Specialist needs to determine what caused the CPU spike.
Which combination of steps should be taken to provide more visibility into the processes and queries
running during an increase in CPU load? (Choose two.)
A financial services company is developing a shared data service that supports different applications
from throughout the company. A Database Specialist designed a solution to leverage Amazon
ElastiCache for Redis with cluster mode enabled to enhance performance and scalability. The cluster
is configured to listen on port 6379.
Which combination of steps should the Database Specialist take to secure the cache data and protect
it from unauthorized access? (Choose three.)
A company is load testing its three-tier production web application deployed with an AWS
CloudFormation template on AWS. The Application team is making changes to deploy additional
Amazon EC2 and AWS Lambda resources to expand the load testing capacity. A Database Specialist
wants to ensure that the changes made by the Application team will not change the Amazon RDS
database resources already deployed.
Which combination of steps would allow the Database Specialist to accomplish this? (Choose two.)
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?
A company is planning to close for several days. A Database Specialist needs to stop all applications
along with the DB instances to ensure employees do not have access to the systems during this time.
All databases are running on Amazon RDS for MySQL.
The Database Specialist wrote and executed a script to stop all the DB instances. When reviewing the
logs, the Database Specialist found that Amazon RDS DB instances with read replicas did not stop.
How should the Database Specialist edit the script to fix this issue?
A company is writing a new survey application to be used with a weekly televised game show. The
application will be available for 2 hours each week. The company expects to receive over 500,000
entries every week, with each survey asking 2-3 multiple choice questions of each user. A Database
Specialist needs to select a platform that is highly scalable for a large number of concurrent writes to
handle he anticipated volume.
Which AWS services should the Database Specialist consider? (Choose two.)
