Question 69

A company uses Amazon RDS (or PostgreSQL to run its applications in the us-east-1 Region. The company also uses machine learning (ML) models to forecast annual revenue based on neat real-time reports. The reports are generated by using the same RDS for PostgreSQL database. The database performance slows during business hours. The company needs to improve database performance.

Which solution will meet these requirements MOST cost-effectively?

Options:

Create a cross-Region read replica. Configure the reports to be generated from the read replica.

Activate Multi-AZ DB instance deployment for RDS for PostgreSQL. Configure the reports to be generated from the standby database.

Use AWS Data Migration Service (AWS DMS) to logically replicate data lo a new database. Configure the reports to be generated from the new database.

Create a read replica in us-east-1. Configure the reports to be generated from the read replica.

Question 70

An online education platform experiences lag and buffering during peak usage hours, when thousands of students access video lessons concurrently. A solutions architect needs to improve the performance of the education platform.

The platform needs to handle unpredictable traffic surges without losing responsiveness. The platform must provide smooth video playback performance at all times. The platform must create multiple copies of each video lesson and store the copies in various bitrates to serve users who have different internet speeds. The smallest video size is 7 GB.

Which solution will meet these requirements MOST cost-effectively?

Options:

Use Amazon ElastiCache to cache videos in all the required bitrates. Use AWS Lambda functions to process the videos and to convert the videos to the required bitrates.

Create an Auto Scaling group that includes Amazon EC2 instances that are sized to meet peak loads. Use the Auto Scaling group to serve videos. Use the Auto Scaling group to convert the videos to the required bitrates.

Store a copy of every video in every required bitrate in an Amazon S3 bucket. Use a single Amazon EC2 instance to serve the videos.

Use Amazon Kinesis Video Streams to store and serve the videos. Use AWS Lambda functions to process the videos and to convert the videos to the required bitrates.

Question 71

An e-commerce company stores inventory, order, and user information in multiple Amazon Redshift clusters. The Redshift clusters must comply with the company ' s security policies. The company must receive notifications about any security configuration violations.

Which solution will meet these requirements?

Options:

Create an Amazon EventBridge rule that uses the Redshift clusters as the source. Create an AWS Lambda function to evaluate the Redshift cluster security configuration. Configure theLambda function to notify the company of any violations of the security policies. Add the Lambda function as a target of the EventBridge rule.

Create an AWS Lambda function to check the validity of the Redshift cluster security configurations. Create an Amazon EventBridge rule that invokes the Lambda function when Redshift clusters are created. Notify the company of any violations of security policies.

Set up Amazon Redshift Advisor in the company ' s AWS account to monitor cluster configurations. Configure Redshift Advisor to generate notifications for security items that the company must address.

Create an AWS Lambda function to check the Redshift clusters for any violation of the security configurations. Create an AWS Config custom rule to invoke the Lambda function when Redshift cluster security configurations are modified. Provide the compliance state of each Redshift cluster to AWS Config. Configure AWS Config to notify the company of any violations of the security policies.

Answer:

Explanation:

Comprehensive and Detailed Step-by-Step Explanation:

The company needsautomatic monitoringandnotificationsforsecurity violationsin Amazon Redshift clusters.

Option A:❌

Create an Amazon EventBridge rule that uses the Redshift clusters as the source. Create an AWS Lambda function to evaluate the Redshift cluster security configuration. Configure the Lambda function to notify the company of any violations of the security policies. Add the Lambda function as a target of the EventBridge rule.

EventBridgecan trigger actionsbased on events.

However, itdoes not track changesin Redshift security configurations.

Why not?AWS Configis bettersuited forcompliance monitoring.

Question 72

A company hosts a public web application on AWS. The website has a three-tier architecture. The frontend web tier is comprised of Amazon EC2 instances in an Auto Scaling group. The application tier is a second Auto Scaling group. The database tier is an Amazon RDS database.

The company has configured the Auto Scaling groups to handle the application ' s normal level of demand. During an unexpected spike in demand, the company notices a long delay in the startup time when the frontend and application layers scale out. The company needs to improve the scaling performance of the application without negatively affecting the user experience.

Which solution will meet these requirements MOST cost-effectively?

Options:

Decrease the minimum number of EC2 instances for both Auto Scaling groups. Increase the desired number of instances to meet the peak demand requirement.

Configure the maximum number of instances for both Auto Scaling groups to be the number required to meet the peak demand. Create a warm pool.

Increase the maximum number of EC2 instances for both Auto Scaling groups to meet the normal demand requirement. Create a warm pool.

Reconfigure both Auto Scaling groups to use a scheduled scaling policy. Increase the size of the EC2 instance types and the RDS instance types.
