A company is deploying an application in three AWS Regions using an Application Load Balancer Amazon Route 53 will be used to distribute traffic between these Regions. Which Route 53 configuration should a solutions architect use to provide the MOST high-performing experience?
A. Create an A record with a latency policy.
B. Create an A record with a geolocation policy.
C. Create a CNAME record with a failover policy.
D. Create a CNAME record with a geoproximity policy.
A company is running a media store across multiple Amazon EC2 instances distributed across multiple Availability Zones in a single VPC. The company wants a high-performing solution to share data between all the EC2 Instances, and prefers to keep the data within the VPC only.
What should a solutions architect recommend?
A. Create an Amazon S3 bucket and call the service APIs from each instance's application.
B. Create an Amazon S3 bucket and configure all instances to access it as a mounted volume.
C. Configure an Amazon Elastic Block Store (Amazon EBS) volume and mount it across all instances.
D. Configure an Amazon Elastic File System (Amazon EFS) file system and mount it across all instances
A company runs an application that uses multiple Amazon EC2 instances to gather data from its users The data is then processed and transferred to Amazon S3 for long-term storage A review of the application shows that there were long
penods of time when the EC2 instances were not being used A solutions architect needs to design a solution that optimizes utilization and reduces costs.
Which solution meets these requirements?
A. Use Amazon EC2 in an Auto Scaling group with On-Demand instances.
B. Build the application to use Amazon Lightsail with On-Demand Instances
C. Create an Amazon CloudWatch cron job to automatically stop the EC2 instances when there is no activity
D. Redesign the application to use an event-driven design with Amazon Simple Queue Service (Amazon SQS) and AWS Lambda.
A company has a multi-tier application deployed on several Amazon EC2 instances in an Auto Scaling group. An Amazon RDS for Oracle instance is the application'', data layer that uses Oracle-specific PUSQL functions. Traffic to the application has been steadily increasing This is causing the EC2 instances to become overloaded an i RDS instance to run out of storage. The Auto Scaling group does not have any scaling metrics and defines the minimum healthy instance count only. The company predicts that traffic will continue to increase at a steady but unpredictable rate before leveling off.
What should a solutions architect do to ensure the system can automatically scale for the increased traffic? (Select TWO)
A. Configure storage Auto Scaling on the RDS for Oracle instance.
B. Migrate the database to Amazon Aurora to use Auto Scaling storage
C. Configure an alarm on the RDS for Oracle instance for low free storage space.
D. Configure the Auto Scaling group to use the average CPU as the scaling metric.
E. Configure the Auto Scaling group to use the average free memory as the scaling metric.
A company is preparing to launch a public-facing web application in the AWS Cloud The architecture consists of Amazon EC2 instances within a VPC behind an Elastic Load Balancer (ELB). A third party service is used for the DNS. The
company's solutions architect must recommend a solution to detect and protect against large scale DDoS attacks.
Which solution meets these requirements?
A. Enable Amazon GuardDuty on the account
B. Enable Amazon Inspector on the EC2 instances
C. Enable AWS Shield and assign Amazon Route 53 to it.
D. Enable AWS Shield Advanced and assign the ELB to it
A company wants to migrate its MySQL database from on premises to AWS. The company recently experienced a database outage that significantly impacted the business. To ensure this does not happen again, the company wants a
reliable database solution on AWS that minimizes data loss and stores every transaction on at least two nodes.
Which solution meets these requirements?
A. Create an Amazon RDS DB instance with synchronous replication to three nodes in three Availability Zones.
B. Create an Amazon RDS MySQL DB instance with Multi-AZ functionality enabled to synchronously replicate the data
C. Create an Amazon RDS MySQL DB instance and then create a read replica in a separate AWS Region that synchronously replicates the data.
D. Create an Amazon EC2 instance with a MySQL engine installed that triggers an AWS Lambda function to synchronously replicate the data to an Amazon RDS MySQL DB instance.
A company has a three-tier environment on AWS that ingests sensor data from its users
A company hosts an application used to upload files to an Amazon S3 bucket Once uploaded, the files are processed to extract metadata, which takes less than 5 seconds. The volume and frequency of the uploads vanes from a few files
each hour to hundreds of concurrent uploads. The company has asked a solutions architect to design a cost effective architecture that will meet these requirements.
What should the solutions architect recommend?
A. Configure AWS CloudTrail trails to log S3 API calls Use AWS AppSync to process the files
B. Configure an object-created event notification within the S3 bucket to invoke an AWS Lambda function to process the files.
C. Configure Amazon Kinesis Data Streams to process and send data to Amazon S3 Invoke an AWS Lambda function to process the files
D. Configure an Amazon Simple Notification Service (Amazon SNS) topic to process the files uploaded to Amazon S3. Invoke an AWS Lambda function to process the files.
A company has an on-premises application that generates a large amount of time-sensitive data that is backed up to Amazon S3. The application has grown and there are user complaints about internet bandwidth limitations. A solutions
architect needs to design a long term solution that allows for both timely backups to Amazon S3 and with minimal impact on internet connectivity tor internal users.
Which solution meets these requirements?
A. Establish AWS VPN connections and proxy all traffic through a VPC gateway endpoint
B. Establish a new AWS Direct Connect connection and direct backup traffic through this new connection
C. Order daily AWS Snowball devices Load the data onto the Snowball devices and return the devices to AWS each day
D. Submit a support ticket through the AWS Management Console Request the removal of S3 service limits from the account.
Management has decided to deploy all AWS VPCs with IPv6 enabled After some time a solutions architect tries to launch a new instance and receives an error stating that there is not enough IP address space available in the subnet What should the solutions architect do to fix this?
A. Check to make sure that only IPv6 was used during the VPC creation.
B. Create a new IPv4 subnet with a larger range, and then launch the instance
C. Create a new IPv6-only subnet with a larger range, and then launch the instance
D. Disable the IPv4 subnet and migrate all instances to IPv6 only Once that is complete launch the instance
