A company has a highly dynamic batch processing job that uses many Amazon EC2 instances to complete it. The job is stateless in nature, can be started and stopped at any given time with no negative impact, and typically takes upwards of 60 minutes total to complete The company has asked a solutions architect to design a scalable and cost-effective solution that meets the requirements of the job.
What should the solutions architect recommend?
A. Implement EC2 Spot Instances
B. Purchase EC2 Reserved Instances
C. Implement EC2 On-Demand Instances
D. Implement the processing on AWS Lambda
A company has an application hosted on Amazon EC2 instances in two VPCs across different AWS Regions To communicate with each other, the instances use the internet for connectivity. The security team wants to ensure that no communication between the instances happens over the internet What should a solutions architect do to accomplish this''
A. Create a NAT gateway and update the route table of the EC2 instances' subnet
B. Create a VPC endpoint and update the route table of the EC2 instances' subnet
C. Create a VPN connection and update the route table of the EC2 instances' subnet
D. Create a VPC peering connection and update the route table of the EC2 instances' subnet
A company runs a production application on a fleet of Amazon EC2 instances The application reads the data from an Amazon SQS queue and processes the messages in parallel. The message volume is unpredictable and often has intermittent traffic. This application should continually process messages without any downtime Which solution meets these requirements MOST cost-effectively?
A. Use Spot Instances exclusively to handle the maximum capacity required
B. Use Reserved Instances exclusively to handle the maximum capacity required
C. Use Reserved Instances for the baseline capacity and use Spot InstaKes to handle additional capacity
D. Use Reserved instances for the baseline capacity and use On-Demand Instances to handle additional capacity
A company with facilities in North America Europe, and Asia is designing new distributed application to optimize its global supply chain and manufacturing process. The orders booked on one continent should be visible to all Regions in a second or less. The database should be able to support failover with a short Recovery Time Objective (RTO) The uptime of the application is important to ensure that manufacturing is not impacted What should a solutions architect recommend?
A. Use Amazon DynamoDB global tables
B. Use Amazon Aurora Global Database
C. Use Amazon RDS for MySQL with a cross-Region read replica
D. Use Amazon RDS for PostgreSQL with a cross-Region read replica
A company has several Amazon EC2 instances set up in a private subnet for security reasons These instances host applications that read and write large amounts of data to and from Amazon S3 regularly. Currently, subnet routing directs all the traffic destined for the internet through a NAT gateway The company wants to optimize the overall cost without impacting the ability of the application to communicate with Amazon S3 or the outside internet What should a solutions architect do to optimize costs?
A. Create an additional NAT gateway Update the route table to route to the NAT gateway Update the network ACL to allow S3 traffic
B. Create an internet gateway Update the route table to route traffic to the internet gateway Update the network ACL to allow S3 traffic.
C. Create a VPC endpoint for Amazon S3 Attach an endpoint policy to the endpoint Update the route table to direct traffic to the VPC endpoint
D. Create an AWS Lambda function outside of the VPC to handle S3 requests Attach an IAM policy to the EC2 instances, allowing them to invoke the Lambda function.
A company hosts a training site on a fleet of Amazon EC2 instances. The company anticipates that its new course, which consists of dozens of training videos on the site, will be extremely popular when it is released in 1 week. What should a solutions architect do to minimize the anticipated server load?
A. Store the videos in Amazon ElastiCache for Redis Update the web servers to serve the videos using the Elastic ache API
B. Store the videos in Amazon Elastic File System (Amazon EFS) Create a user data script for the web servers to mount the EFS volume.
C. Store the videos in an Amazon S3 bucket Create an Amazon CloudFlight distribution with an origin access identity (OAI) of that S3 bucket Restrict Amazon S3 access to the OAI.
D. Store the videos in an Amazon S3 bucket. Create an AWS Storage Gateway file gateway to access the S3 bucket Create a user data script for the web servers to mount the file gateway
A company wants to reduce Its Amazon S3 storage costs in its production environment without impacting durability or performance of the stored objects What is the FIRST step the company should take to meet these objectives?
A. Enable Amazon Made on the business-critical S3 buckets lo classify the sensitivity of the objects
B. Enable S3 analytics to Identify S3 buckets that are candidates for transitioning to S3 Standard- Infrequent Access (S3 Standard-IA)
C. Enable versioning on all business-critical S3 buckets.
D. Migrate me objects in all S3 buckets to S3 Intelligent-Tie ring
A company wants to improve the availability of an existing firewall. To meet the compliance requirements of the applications hosted in the VPC. the company's security team is using a proprietary firewall running on Amazon EC2 instances All internet traffic flows through the primary firewall. When the primary firewall goes down, the team manually changes the VPC route table so that it uses a secondary firewall running in a different Availability Zone. Which strategies should a solutions architect use to improve the availability of the firewall? (Select TWO.)
A. Create an EC2 gateway endpoint In the VPC where the firewall is hosted.
B. Create an EC2 interface endpoint in the VPC where the firewall is hosted.
C. Enable enhanced networking on the EC2 instance running the proprietary firewall
D. Deploy a scheduled AWS Lambda function in the VPC to monitor the primary firewall and change the route table to use the secondary firewall in case of failure.
E. Monitor the firewall instance health in Amazon EventBridge (Amazon CloudWatch Events). Trigger an event rule to restart the primary firewall upon a detected failure.
A company is deploying a production portal application on AWS. The database tier has structured data
The company requires a solution that is easily manageable and highly available How can these requirements be met?
A. Deploy the database on multiple Amazon EC2 instances backed by Amazon Elastic Block Store (Amazon EBS) across multiple Availability Zones.
B. Use Amazon RDS with a multiple Availability Zone option
C. Use Amazon RDS with a single Availability Zone option and schedule periodic database snapshots.
D. Use Amazon DynamoDB
