7An AWS Lambda function requires access to an Amazon RDS for SQL Server instance. It is
against company policy to store passwords in Lambda functions.
How can a Solution Architect enable the Lambda function to retrieve the database password without
violating company policy?- AStore a one-way hash of the password in the Lambda function
- BConnect to the Amazon RDS for SQL Server instance by using a role assigned to the Lambda function
- CHave the Lambda function use the AWS Systems Manager Parameter Store
- DAdd an IAM policy for IAM database access to the Lambda execution role
8Which combination of two policies enables AWS identity and access management cross-
account access?Choose 2 answers- APermission policy
- BTrust policy
- CAccess policy
- DBucket policy
- EKey policy
9A stray Amazon EC2 r3.8xlarge instance is running in your AWS account. Before terminating it,
you want to find the owner to confirm that it is not needed.
Where can you find the identity that launched this instance?- AVPC flow logs
- BOperating system logs
- CCloudTrail logs
- DELB access logs
10You have a distributed application that periodically processes large volumes of data across
multiple Amazon EC2 Instances. The application is designed to recover gracefully from Amazon EC2
instance failures. You are required to accomplish this task in the most cost-effective way. Which of
the following will meet your requirements?- AOn-Demand instances
- BReserved instances
- CSpot Instances
- DDedicated instances
11A customer is running a multi-tier web application farm in a virtual private cloud (VPC) that is
not connected to their corporate network. They are connecting to the VPC.
Which of the following bastion deployment scenarios will meet this requirement?- ADeploy a Windows Bastion host with an auto-assigned Public subnet, and allow RDP access to the bastion from only the corporate public IP addresses
- BDeploy a Windows Bastion host on the corporate network that has RDP access to all intances in the VPC
- CDeploy a Windows Bastion host with an Elastic IP address in the private subnet, and restrict RDP access to the bastion from only the corporate public IP addresses
- DDeploy a Windows Bastion host with an Elastic IP address in the public subnet, and allow SSH access to the bastion from anywhere
12A company has an Amazon RDS-managed online transaction processing system that has very
heavy read and write. The Solutions Architect notices throughput issues with the system.
How can the responsiveness of the primary database be improved?- AOffload SELECT query that needs the most current data to READ replica.
- BUse asynchronous replication for standby to maximize throughput during peak demand.
- COffload SELECT queries that can tolerate stale data to READ replica.
- DOffload SELECT and UPDATE queries to READ replica.
13Your application contains thousands of Images in an Amazon RDS MySQL instance. These
images are frequently accessed and the number of images is growing rapidly. Which should you
implement to reduce cost and improve application performance?- AMigrate the images to Amazon Elastic Block Store volumes, and allow the end users to access the images through Amazon CloudFront
- BMigrate the images to Amazon Glacier, and allow the end users to access the images through Amazon CloudFront
- CCreate two Amazon RDS My SQL read replicas in different regions, and migrate the images to the cross-region read replicas
- DMigrate the images to Amazon Simple Storage Service, and allow the end udders to access the images through Amazon CloudFront
14You are designing a web application that stores static assets in an Amazon Simple Storage
Service (S3) bucket. You expect this bucket to immediately receive over 150 PUT requests per second.
What should you do to ensure optimal performance?- AAdd a random prefix to the key names.
