A monolithic application was recently migrated to AWS and is now running on a single Amazon EC2 instance. Due to application limitations, it is not possible to use automatic scaling to scale out the application. The chief technology officer (CTO) wants an automated solution to restore the EC2 instance in the unlikely event the underlying hardware fails. What would allow for automatic recovery of the EC2 instance as quickly as possible?
A. Configure an Amazon CloudWatch alarm that triggers the recovery of the EC2 instance if it becomes impaired.
B. Configure an Amazon CloudWatch alarm to trigger an SNS message that alerts the CTO when the EC2 instance is impaired.
C. Configure AWS CloudTrail to monitor the health of the EC2 instance, and if it becomes impaired, triggered instance recovery.
D. Configure an Amazon EventBridge event to trigger an AWS Lambda function once an hour that checks the health of the EC2 instance and triggers instance recovery if the EC2 instance is unhealthy.
A company has created a VPC with multiple private subnets in multiple Availability Zones (AZs) and one public subnet in one of the AZs. The public subnet is used to launch a NAT gateway. There are instance in the private subnet that use a
NAT gateway to connect to the internet. In case of an AZ failure, the company wants to ensure that the instance are not all experiencing internet connectivity issues and that there is a backup plan ready.
Which solution should a solutions architect recommend that is MOST highly available?
A. Create a new public subnet with a NAT gateway in the same AZ Distribute the traffic between the two NAT gateways
B. Create an Amazon EC2 NAT instance in a now public subnet Distribute the traffic between the NAT gateway and the NAT instance
C. Create public subnets In each AZ and launch a NAT gateway in each subnet Configure the traffic from the private subnets In each A2 to the respective NAT gateway
D. Create an Amazon EC2 NAT instance in the same public subnet Replace the NAT gateway with the NAT instance and associate the instance with an Auto Scaling group with an appropriate scaling policy.
A company uses Amazon S3 as its object storage solution. The company has thousands of S3 it uses to store data
Some of the S3 bucket have data that is accessed less frequently than others. A solutions architect found that lifecycle policies are not consistently implemented or are implemented partially. resulting in data being stored in high-cost storage.
Which solution will lower costs without compromising the availability of objects?
A. Use S3 ACLs
B. Use Amazon Elastic Block Store EBS) automated snapshots
C. Use S3 intelligent-Tiering storage
D. Use S3 One Zone-infrequent Access (S3 One Zone-IA).
A solution architect must migrate a Windows internet information Services (IIS) web application to AWS. The application currently relies on a file share hosted in the user's on-premises network- attached storage (NAS). The solution architected has proposed migrating the IIS web servers Which replacement to the on-promises filo share is MOST resilient and durable?
A. Migrate the file Share to Amazon RDS.
B. Migrate the tile Share to AWS Storage Gateway
C. Migrate the file Share to Amazon FSx dor Windows File Server.
D. Migrate the tile share to Amazon Elastic File System (Amazon EFS)
A company needs to share an Amazon S3 bucket with an external vendor. The bucket owner must be able to access all objects. Which action should be taken to share the S3 bucket?
A. Update the bucket to be a Requester Pays bucket
B. Update the bucket to enable cross-origin resource sharing (CPORS)
C. Create a bucket policy to require users to grant bucket-owner-full when uploading objects
D. Create an IAM policy to require users to grant bucket-owner-full control when uploading objects.
A company is developing a real-time multiplier game that uses UDP for communications between client and servers in an Auto Scaling group Spikes in demand are anticipated during the day, so the game server platform must adapt
accordingly. Developers want to store gamer scores and other non- relational data in a database solution that will scale without intervention.
Which solution should a solution architect recommend?
A. Use Amazon Route 53 for traffic distribution and Amazon Aurora Serverless for data storage.
B. Use a Network Load Balancer for traffic distribution and Amazon DynamoDB on-demand for data storage.
C. Use a Network Load Balancer for traffic distribution and amazon Aura Global for data storage.
D. Use an Application Load Balancer for traffic distribution and Amazon DynamoDB global tables for data storage
A company currently has 250 TB of backup files stored in Amazon S3 in a vendor's proprietary format. Using a Linux-based software application provided by the vendor, the company wants to retrieve files from Amazon S3, transform the files to an industry-standard format, and re-upload them to Amazon S3. The company wants to minimize the data transfer charges associated with this conversation. What should a solution architect do to accomplish this?
A. Install the conversion software as an Amazon S3 batch operation so the data is transformed without leaving Amazon S3.
B. Install the conversion software onto an on-premises virtual machines. Perform the transformation and re-upload the files to Amazon S3 from the virtual machine.
C. Use AWS Snowball Edge device to expert the data and install the conversion software onto the devices. Perform the data transformation and re-upload the files to Amazon S3 from the Snowball devices.
D. Launch an Amazon EC2 instance in the same Region as Amazon S3 and install the conversion software onto the instance. Perform the transformation and re-upload the files to Amazon S3 from the EC2 instance.
A company has an Amazon EC2 instance running on a private subnet that needs to access a public websites to download patches and updates. The company does not want external websites to see the EC2 instance IP address or initiate
connection to it.
How can a solution architect achieve this objective?
A. Create a site-to-site VPN connection between the private subnet and the network in which the public site is deployed
B. Create a NAT gateway in a public subnet Route outbound traffic from the private subnet through the NAI gateway
C. Create a network ACL for the private subnet where the EC2 instance deployed only allows access from the IP address range of the public website
D. Create a security group that only allows connections from the IP address range of the public website. Attach the security group to the EC2 instance.
A company must re-evaluate its need for the Amazon EC2 instances it currently has provisioned in an Auto Scaling group. At present, the Auto Scaling group is configured for minimum of two instances and a maximum of four instances across two Availability zones. A Solutions architect reviewed Amazon CloudWatch metrics and found that CPU utilization is consistently low for the EC2 instances. What should the solutions architect recommend to maximize utilization while ensuring the application remains fault tolerant?
A. Remove some EC2 instances to increase the utilization of remaining instances.
B. Increase the Amazon Elastic Block Store (Amazon EBS) capacity of instances with less CPU utilization.
C. Modify the Auto Scaling group scaling policy to scale in and out based on a higher CPU utilization metric.
D. Create a new launch configuration that uses smaller instance types. Update the existing Auto Scaling group.
A company's website provides users with downloadable historical performance reports. The website needs a solution that will scale to meet the company's website demands globally. The solution should be cost effective, limit the?
provisioning of Into and provide the fastest possible response time.
Which combination should a solutions architect recommend to meet these requirements?
A. Amazon CloudFront and Amazon S3
B. AWS Lambda and Amazon Dynamo
C. Application Load Balancer with Amazon EC2 Auto Scaling
D. Amazon Route 53 with internal Application Load Balances
