Question 116

A company runs a real-time data ingestion solution on AWS. The solution consists of the most recent version of Amazon Managed Streaming for Apache Kafka (Amazon MSK). The solution is deployed in a VPC in private subnets across three Availability Zones.

A solutions architect needs to redesign the data ingestion solution to be publicly available over the internet. The data in transit must also be encrypted.

Which solution will meet these requirements with the MOST operational efficiency?

Options:

Configure public subnets in the existing VPC. Deploy an MSK cluster in the public subnets. Update the MSK cluster security settings to enable mutual TLS authentication.

Create a new VPC that has public subnets. Deploy an MSK cluster in the public subnets. Update the MSK cluster security settings to enable mutual TLS authentication.

Deploy an Application Load Balancer (ALB) that uses private subnets. Configure an ALB security group inbound rule to allow inbound traffic from the VPC CIDR block for HTTPS protocol.

Deploy a Network Load Balancer (NLB) that uses private subnets. Configure an NLB listener for HTTPS communication over the internet.

Question 117

A company has stored 10 TB of log files in Apache Parquet format in an Amazon S3 bucket The company occasionally needs to use SQL to analyze the log files Which solution will meet these requirements MOST cost-effectively?

Options:

Create an Amazon Aurora MySQL database Migrate the data from the S3 bucket into Aurora by using AWS Database Migration Service (AWS DMS) Issue SQL statements to the Aurora database.

Create an Amazon Redshift cluster Use Redshift Spectrum to run SQL statements directly on the data in the S3 bucket

Create an AWS Glue crawler to store and retrieve table metadata from the S3 bucket Use Amazon Athena to run SQL statements directly on the data in the S3 bucket

Create an Amazon EMR cluster Use Apache Spark SQL to run SQL statements directly on the data in the S3 bucket

Question 118

A company has deployed a multiplayer game for mobile devices. The game requires live location tracking of players based on latitude and longitude. The data store for the game must support rapid updates and retrieval of locations.

The game uses an Amazon RDS for PostgreSQL DB instance with read replicas to store the location data. During peak usage periods, the database is unable to maintain the performance that is needed for reading and writing updates. The game's user base is increasing rapidly.

What should a solutions architect do to improve the performance of the data tier?

Options:

Take a snapshot of the existing DB instance. Restore the snapshot with Multi-AZ enabled.

Migrate from Amazon RDS to Amazon OpenSearch Service with OpenSearch Dashboards.

Deploy Amazon DynamoDB Accelerator (DAX) in front of the existing DB instance. Modify the game to use DAX.

Deploy an Amazon ElastiCache for Redis cluster in front of the existing DB instance. Modify the game to use Redis.

Discussion

Answer:

Explanation:

The solution that will improve the performance of the data tier is to deploy an Amazon ElastiCache for Redis cluster in front of the existing DB instance and modify the game to use Redis. This solution will enable the game to store and retrieve the location data of the players in a fast and scalable way, as Redis is an in-memory data store that supports geospatial data types and commands. By using ElastiCache for Redis, the game can reduce the load on the RDS for PostgreSQL DB instance, which is not optimized for high-frequency updates and queries of location data. ElastiCache for Redis also supports replication, sharding, and auto scaling to handle the increasing user base of the game.

The other solutions are not as effective as the first one because they either do not improve the performance, do not support geospatial data, or do not leverage caching. Taking a snapshot of the existing DB instance and restoring it with Multi-AZ enabled will not improve the performance of the data tier, as it only provides high availability and durability, but not scalability or low latency. Migrating from Amazon RDS to Amazon OpenSearch Service with OpenSearch Dashboards will not improve the performance of the data tier, as OpenSearch Service is mainly designed for full-text search and analytics, not for real-time location tracking. OpenSearch Service also does not support geospatial data types and commands natively, unlike Redis. Deploying Amazon DynamoDB Accelerator (DAX) in front of the existing DB instance and modifying the game to use DAX will not improve the performance of the data tier, as DAX is only compatible with DynamoDB, not with RDS for PostgreSQL. DAX also does not support geospatial data types and commands.

Question 119

A company has an application that delivers on-demand training videos to students around the world. The application also allows authorized content developers to upload videos. The data is stored in an Amazon S3 bucket in the us-east-2 Region.

The company has created an S3 bucket in the eu-west-2 Region and an S3 bucket in the ap-southeast-1 Region. The company wants to replicate the data to the new S3 buckets. The company needs to minimize latency for developers who upload videos and students who stream videos near eu-west-2 and ap-southeast-1.

Which combination of steps will meet these requirements with the FEWEST changes to the application? (Select TWO.)

Options:

Configure one-way replication from the us-east-2 S3 bucket to the eu-west-2 S3 bucket. Configure one-way replication from the us-east-2 S3 bucket to the ap-southeast-1 S3 bucket.

Configure one-way replication from the us-east-2 S3 bucket to the eu-west-2 S3 bucket. Configure one-way replication from the eu-west-2 S3 bucket to the ap-southeast-1 S3 bucket.

Configure two-way (bidirectional) replication among the S3 buckets that are in all three Regions.

Create an S3 Multi-Region Access Point. Modify the application to use the Amazon Resource Name (ARN) of the Multi-Region Access Point for video streaming. Do not modify the application for video uploads.

Create an S3 Multi-Region Access Point Modify the application to use the Amazon Resource Name (ARN) of the Multi-Region Access Point for video streaming and uploads.
