Question 196

A company wants to use the AWS Cloud to make an existing application highly available and resilient. The current version of the application resides in the company's data center. The application recently experienced data loss after a database server crashed because of an unexpected power outage.

The company needs a solution that avoids any single points of failure. The solution must give the application the ability to scale to meet user demand.

Which solution will meet these requirements?

Options:

Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones. Use an Amazon RDS DB instance in a Multi-AZ configuration.

Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group in a single Availability Zone. Deploy the database

on an EC2 instance. Enable EC2 Auto Recovery.

Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones. Use an Amazon RDS DB instance with a read replica in a single Availability Zone. Promote the read replica to replace the primary DB instance if the primary DB instance fails.

Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones Deploy the primary and secondary database servers on EC2 instances across multiple Availability Zones Use Amazon Elastic Block Store (Amazon EBS) Multi-Attach to create shared storage between the instances.

Question 197

A company has a mulli-tier application that runs six front-end web servers in an Amazon EC2 Auto Scaling group in a single Availability Zone behind an Application Load Balancer (ALB). A solutions architect needs lo modify the infrastructure to be highly available without modifying the application.

Which architecture should the solutions architect choose that provides high availability?

Options:

Create an Auto Scaling group that uses three Instances across each of tv/o Regions.

Modify the Auto Scaling group to use three instances across each of two Availability Zones.

Create an Auto Scaling template that can be used to quickly create more instances in another Region.

Change the ALB in front of the Amazon EC2 instances in a round-robin configuration to balance traffic to the web tier.

Question 198

A company has a data ingestion workflow that includes the following components:

• An Amazon Simple Notation Service (Amazon SNS) topic that receives notifications about new data deliveries

• An AWS Lambda function that processes and stores the data

The ingestion workflow occasionally fails because of network connectivity issues. When tenure occurs the corresponding data is not ingested unless the company manually reruns the job. What should a solutions architect do to ensure that all notifications are eventually processed?

Options:

Configure the Lambda function (or deployment across multiple Availability Zones

Modify me Lambda functions configuration to increase the CPU and memory allocations tor the (unction

Configure the SNS topic's retry strategy to increase both the number of retries and the wait time between retries

Configure an Amazon Simple Queue Service (Amazon SQS) queue as the on failure destination Modify the Lambda function to process messages in the queue

Question 199

A company is running a multi-tier web application on premises. The web application is containerized and runs on a number of Linux hosts connected to a PostgreSQL database that contains user records. The operational overhead of maintaining the infrastructure and capacity planning is limiting the company's growth. A solutions architect must improve the application's infrastructure.

Which combination of actions should the solutions architect take to accomplish this? (Choose two.)

Options:

Migrate the PostgreSQL database to Amazon Aurora

Migrate the web application to be hosted on Amazon EC2 instances.

Set up an Amazon CloudFront distribution for the web application content.

Set up Amazon ElastiCache between the web application and the PostgreSQL database.

Migrate the web application to be hosted on AWS Fargate with Amazon Elastic Container Service (Amazon ECS).
