A data visualization company wants to strengthen the security of its core applications The applications are deployed on AWS across its development staging, pre-production, and production environments. The company needs to encrypt all of its stored sensitive credentials The sensitive credentials need to be automatically rotated Aversion of the sensitive credentials need to be stored for each environment Which solution will meet these requirements in the MOST operationally efficient way?

A : Configure AWS Secrets Manager versions to store different copies of the same credentials across multiple environments

B : Create a new parameter version in AWS Systems Manager Parameter Store for each environment Store the environment-specific credentials in the parameter version.

C : Configure the environment variables in the application code Use different names for each environment type

D : Configure AWS Secrets Manager to create a new secret for each environment type. Store the environment-specific credentials in the secret

Answer: D

Question 2

A company runs a booking system for a medical practice. The AWS SDK is used to communicate with between several AWS services. Due to compliance requirements, the security department has requested that a record is made of all API calls. How can this requirement be met?

B : Amazon CloudWatch logs to keep a history of API calls

C : Amazon CloudTrail to keep a history of API calls

D : AWS X-Ray to trace the API calls and keep a record

Answer: C

Question 3

An application needs to use the IP address of the client in its processing. The application has been moved into AWS and has been placed behind an Application Load Balancer (ALB). However, all the client IP addresses now appear to be the same. The application must maintain the ability to scale horizontally.

Based on this scenario, what is the MOST cost-effective solution to this problem?

A : Remove the application from the ALB. Delete the ALB and change Amazon Route 53 to direct traffic to the instance running the application.

B : Remove the application from the ALCreate a Classic Load Balancer in its place. Direct traffic to the application using the HTTP protocol.

C : Alter the application code to inspect the X-Forwarded-For header. Ensure that the code can work properly if a list of IP addresses is passed in the header.

D : Alter the application code to inspect a custom header. Alter the client code to pass the IP address in the custom header.

Answer: C

Question 4

An application resizes images that are uploaded to an Amazon S3 bucket. Amazon S3 event notifications are used to trigger an AWS Lambda function that resizes the images. The processing time for each image is less than one second. A large amount of images are expected to be received in a short burst of traffic. How will AWS Lambda accommodate the workload?

A : mbda will collect and then batch process the images in a single execution

B : mbda will scale the memory allocated to the function to increase the amount of CPU available to process many images

C : mbda will process the images sequentially in the order they are received

D : mbda will scale out and execute the requests concurrently

Answer: D

Question 5

A Developer needs to scan a full DynamoDB 50GB table within non-peak hours. About half of the strongly consistent RCUs are typically used during non-peak hours and the scan duration must be minimized.

How can the Developer optimize the scan execution time without impacting production workloads?

A : crease the RCUs during the scan operation

B : sequential scans

C : ange to eventually consistent RCUs during the scan operation

D : parallel scans while limiting the rate

Answer: D
