Amazon SAA-C02 Online Questions & Answers

• Question 721:

  A company that operates a web application on premises is preparing to launch a newer version of the application on AWS. The company needs to route requests to either the AWS-hosted or the on-premises-hosted application based on the URL query string. The on-premises application is not available from the internet, and a VPN connection is established between Amazon VPC and the company's data center. The company wants to use an Application Load Balancer (ALB) for this launch.

  Which solution meets these requirements?

  A. Use two ALBs: one for on-premises and one for the AWS resource. Add hosts to each target group of each ALB. Route with Amazon Route 53 based on the URL query string.
  B. Use two ALBs: one for on-premises and one for the AWS resource. Add hosts to the target group of each ALB. Create a software router on an EC2 instance based on the URL query string.
  C. Use one ALB with two target groups: one for the AWS resource and one for on premises. Add hosts to each target group of the ALB. Configure listener rules based on the URL query string.
  D. Use one ALB with two AWS Auto Scaling groups: one for the AWS resource and one for on premises. Add hosts to each Auto Scaling group. Route with Amazon Route 53 based on the URL query string.
  C. Use one ALB with two target groups: one for the AWS resource and one for on premises. Add hosts to each target group of the ALB. Configure listener rules based on the URL query string.

• Question 722:

  A company is using a fleet of Amazon EC2 instances to ingest data from on-premises data sources. The data is in JSON format and ingestion rates can be as high as 1 MB/s. When an EC2 instance is rebooted, the data in-flight is lost. The

  company's data science team wants to query ingested data in near-real time.

  Which solution provides near-real-time data querying that is scalable with minimal data loss?

  A. Publish data to Amazon Kinesis Data Streams. Use Kinesis Data Analytics to query the data.
  B. Publish data to Amazon Kinesis Data firehose with Amazon Redshift as the destination. Use Amazon Redshift to query the data.
  C. Store ingested data in an EC2 instance store Publish data to Amazon Kinesis Data Firehose with Amazon S3 as the destination. Use Amazon Athena to query the data.
  D. Store ingested data in an Amazon Elastic Block Store (Amazon EBS) volume. Publish data to Amazon ElastiCache for Redis. Subscribe to the Redis channel to query the data.

  A. Private endpoint
  B. Regional endpoint
  C. Interface VPC endpoint
  D. Edge-optimized endpoint
  A. Private endpoint

• Question 724:

  A solutions architect must analyze and update a company's existing IAM policies prior to deploying a new workload. The solutions architect created the following policy:

  B. Users win be allowed all actions except s3 PutObject if multi-factor authentication (MFA) is not enabled
  C. Users will be denied all actions except s3;PutObject if multi-factor authentication (MFA) is enabled.
  D. Users win be denied all actions except s3:PutObject if multi-factor authentication (MFA) is not enabled.
  C. Users will be denied all actions except s3;PutObject if multi-factor authentication (MFA) is enabled.

• Question 725:

  A financial services company wants to shut down two data centers and migrate more than 100 TB of data to AWS. The data has an intricate directory structure with millions of small files stored in deep hierarchies of subfolders Most of the data is unstructured and the company's file storage consists of SMB-based storage types from multiple vendors The company does not want to change its applications to access the data after migration.

  What should a solutions architect do to meet these requirements with the LEAST operational overhead?

  A. Use AWS Direct Connect to migrate the data to Amazon S3 .
  B. Use AWS DataSync to migrate the data to Amazon FSx for Lustre
  C. Use AWS DataSync to migrate the data to Amazon FSx for Windows File Server
  D. Use AWS Direct Connect to migrate the data on-premises file storage to an AWS Storage Gateway volume gateway.
  D. Use AWS Direct Connect to migrate the data on-premises file storage to an AWS Storage Gateway volume gateway.

• Question 726:

  A manufacturing company has machine sensors that upload csv files to an Amazon S3 bucket These csv files must be converted into images and must be made available as soon as possible for the automatic generation of graphical reports

  The images become irrelevant after 1 month, but the csv files must be kept to tram machine learning (ML) models twice a year. The ML trainings and audits are planned weeks in advance. Which combination of steps will meet these requirements MOST cost-effectively? (Select TWO )

  A. Launch an Amazon EC2 Spot Instance that downloads the csv files every hour generates the image files, and uploads the images to the S3 bucket
  B. Design an AWS Lambda function that converts the csv files into images and stores the images in the S3 bucket Invoke the Lambda function when a csv file is uploaded
  C. Create S3 Lifecycle rules for csv files and image files in the S3 bucket Transition the csv files from S3 Standard to S3 Glacier 1 day after they are uploaded Expire the image files after 30 days
  D. Create S3 Lifecycle rules for csv files and image files in the S3 bucket Transition the csv files from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) 1 day after they are uploaded Expire the image files after 30 days
  E. Create S3 Lifecycle rules for csv files and image files in the S3 bucket Transition the csv files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 1 day after they are uploaded Keep the image files in Reduced Redundancy Storage (RRS)
  B. Design an AWS Lambda function that converts the csv files into images and stores the images in the S3 bucket Invoke the Lambda function when a csv file is uploaded
  D. Create S3 Lifecycle rules for csv files and image files in the S3 bucket Transition the csv files from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) 1 day after they are uploaded Expire the image files after 30 days
