Your team has a tomcat-based Java application you need to deploy into development, test and production environments. After some research, you opt to use
Elastic Beanstalk due to its tight integration with your developer tools and RDS due to its ease of management. Your QA team lead points out that you need to roll a sanitized set of production data into your environment on a nightly basis. Similarly, other software teams in your org want access to that same restored data via their EC2 instances in your VPC.
The optimal setup for persistence and security that meets the above requirements would be the following.
Select the correct set of options. These are the initial settings for the default security group:
A company wants to establish a dedicated connection between its on-premises infrastructure and AWS. The company is setting up a 1 Gbps AWS Direct Connect connection to its account VPC. The architecture includes a transit gateway and a Direct Connect gateway to connect multiple VPCs and the on-premises infrastructure.
The company must connect to VPC resources over a transit VIF by using the Direct Connect connection.
Which combination of steps will meet these requirements? (Choose two.)
A company's solutions architect needs to provide secure Remote Desktop connectivity to users for Amazon EC2 Windows instances that are hosted in a VPC. The solution must integrate centralized user management with the company's on-premises Active Directory. Connectivity to the VPC is through the internet. The company has hardware that can be used to establish an AWS Site-to-Site VPN connection.
Which solution will meet these requirements MOST cost-effectively?
A company uses AWS Organizations to manage its AWS accounts. The company needs a list of all its Amazon EC2 instances that have underutilized CPU or memory usage. The company also needs recommendations for how to downsize these underutilized instances.
Which solution will meet these requirements with the LEAST effort?
A company uses an on-premises data analytics platform. The system is highly available in a fully redundant configuration across 12 servers in the company's data center.
The system runs scheduled jobs, both hourly and daily, in addition to one-time requests from users. Scheduled jobs can take between 20 minutes and 2 hours to finish running and have tight SLAs. The scheduled jobs account for 65% of the system usage. User jobs typically finish running in less than 5 minutes and have no SLA. The user jobs account for 35% of system usage. During system failures, scheduled jobs must continue to meet SLAs. However, user jobs can be delayed.
A solutions architect needs to move the system to Amazon EC2 instances and adopt a consumption-based model to reduce costs with no long-term commitments. The solution must maintain high availability and must not affect the SLAs.
Which solution will meet these requirements MOST cost-effectively?
A company operates a fleet of servers on premises and operates a fleet of Amazon EC2 instances in its organization in AWS Organizations. The company's AWS accounts contain hundreds of VPCs. The company wants to connect its AWS accounts to its on-premises network. AWS Site-to-Site VPN connections are already established to a single AWS account. The company wants to control which VPCs can communicate with other VPCs.
Which combination of steps will achieve this level of control with the LEAST operational effort? (Choose three.)
A company recently deployed an application on AWS. The application uses Amazon DynamoDB. The company measured the application load and configured the RCUs and WCUs on the DynamoDB table to match the expected peak load. The peak load occurs once a week for a 4-hour period and is double the average load. The application load is close to the average load for the rest of the week. The access pattern includes many more writes to the table than reads of the table.
A solutions architect needs to implement a solution to minimize the cost of the table.
Which solution will meet these requirements?
A solutions architect is auditing the security setup of an AWS Lambda function for a company. The Lambda function retrieves the latest changes from an Amazon Aurora database. The Lambda function and the database run in the same VPC. Lambda environment variables are providing the database credentials to the Lambda function.
The Lambda function aggregates data and makes the data available in an Amazon S3 bucket that is configured for server-side encryption with AWS KMS managed encryption keys (SSE-KMS). The data must not travel across the internet. If any database credentials become compromised, the company needs a solution that minimizes the impact of the compromise.
What should the solutions architect recommend to meet these requirements?
A company is developing and hosting several projects in the AWS Cloud. The projects are developed across multiple AWS accounts under the same organization in AWS Organizations. The company requires the cost for cloud infrastructure to be allocated to the owning project. The team responsible for all of the AWS accounts has discovered that several Amazon EC2 instances are lacking the Project tag used for cost allocation.
Which actions should a solutions architect take to resolve the problem and prevent it from happening in the future? (Choose three.)
A company that uses AWS Organizations is creating several new AWS accounts. The company is setting up controls to properly allocate AWS costs to business units. The company must implement a solution to ensure that all resources include a tag that has a key of costcenter and a value from a predefined list of business units. The solution must send a notification each time a resource tag does not meet these criteria. The solution must not prevent the creation of resources.
Which solution will meet these requirements with the LEAST operational overhead?
An international delivery company hosts a delivery management system on AWS. Drivers use the system to upload confirmation of delivery. Confirmation includes the recipient's signature or a photo of the package with the recipient. The driver's handheld device uploads signatures and photos through FTP to a single Amazon EC2 instance. Each handheld device saves a file in a directory based on the signed-in user, and the file name matches the delivery number. The EC2 instance then adds metadata to the file after querying a central database to pull delivery information. The file is then placed in Amazon S3 for archiving.
As the company expands, drivers report that the system is rejecting connections. The FTP server is having problems because of dropped connections and memory issues. In response to these problems, a system engineer schedules a cron task to reboot the EC2 instance every 30 minutes. The billing team reports that files are not always in the archive and that the central system is not always updated.
A solutions architect needs to design a solution that maximizes scalability to ensure that the archive always receives the files and that systems are always updated. The handheld devices cannot be modified, so the company cannot deploy a new application.
Which solution will meet these requirements?
How can an EBS volume that is currently attached to an EC2 instance be migrated from one Availability Zone to another?
A company needs to deploy its document storage application across two AWS Regions. The company is storing PDF documents that have an average file size of 512 KiB and a minimum file size of 200 KiB. The company needs protection for accidental document overwrites in the primary Region. The secondary Region must have cost-optimized storage. The company needs a solution that provides an SLA of 99.99% that files will be replicated to the secondary Region within 15 minutes.
Which solution will meet these requirements?
A company has an application that is deployed on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are part of an Auto Scaling group. The application has unpredictable workloads and frequently scales out and in. The company's development team wants to analyze application logs to find ways to improve the application's performance. However, the logs are no longer available after instances scale in.
Which solution will give the development team the ability to view the application logs after a scale-in event?
A company is deploying a new cluster for big data analytics on AWS. The cluster will run across many Linux Amazon EC2 instances that are spread across multiple Availability Zones.
All of the nodes in the cluster must have read and write access to common underlying file storage. The file storage must be highly available, must be resilient, must be compatible with the Portable Operating System Interface (POSIX), and must accommodate high levels of throughput.
Which storage solution will meet these requirements?
A company had a third-party audit of its AWS environment. The auditor identified secrets in developer documentation and found secrets that were hardcoded into AWS CloudFormation templates throughout the environment. The auditor also identified security groups that allowed inbound traffic from the internet and outbound traffic to all destinations on the internet.
A solutions architect must design a solution that will encrypt all secrets and rotate the secrets every 90 days. Additionally, the solutions architect must configure the security groups to prevent resources from being accessible from the internet.
Which solution will meet these requirements?
A company is running an application on Amazon EC2 instances in the AWS Cloud. The application is using a MongoDB database with a replica set as its data tier. The MongoDB database is installed on systems in the company's on-premises data center and is accessible through an AWS Direct Connect connection to the data center environment.
A solutions architect must migrate the on-premises MongoDB database to Amazon DocumentDB (with MongoDB compatibility).
Which strategy should the solutions architect choose to perform this migration?
A company is deploying a new API to AWS. The API uses Amazon API Gateway with a Regional API endpoint and an AWS Lambda function for hosting. The API retrieves data from an external vendor API, stores data in an Amazon DynamoDB global table, and retrieves data from the DynamoDB global table. The API key for the vendor's API is stored in AWS Secrets Manager and is encrypted with a customer managed key in AWS Key Management Service (AWS KMS). The company has deployed its own API into a single AWS Region.
A solutions architect needs to change the API components of the company's API to ensure that the components can run across multiple Regions in an active-active configuration.
Which combination of changes will meet this requirement with the LEAST operational overhead? (Choose three.)
A company deploys workloads in multiple AWS accounts. Each account has a VPC with VPC flow logs published in text log format to a centralized Amazon S3 bucket. Each log file is compressed with gzip compression. The company must retain the log files indefinitely.
A security engineer occasionally analyzes the logs by using Amazon Athena to query the VPC flow logs. The query performance is degrading over time as the number of ingested logs is growing. A solutions architect must improve the performance of the log analysis and reduce the storage space that the VPC flow logs use.
Which solution will meet these requirements with the LARGEST performance improvement?
A company's solutions architect is managing a learning platform that supports more than 1 million students. The company's business reporting team is experiencing slow performance while extracting large datasets from the database. The learning application is based on PHP and runs on Amazon EC2 instances that are in an Amazon EC2 Auto Scaling group behind an Application Load Balancer (ALB). Application data is stored in an Amazon S3 bucket and in an Amazon RDS for MySOL database. The ALB is the origin of an Amazon CloudFront distribution.
The solutions architect observes that slow read operations for SELECT queries are affecting the RDS for MySOL DB instance's CPU utilization. The solutions architect must find a scalable solution to improve the slow website performance with near-zero downtime. The solution also must provide automatic failover with no data loss.
Which solution will meet these requirements?
A company is using IoT devices on its manufacturing equipment. Data from the devices travels to the AWS Cloud through a connection to AWS IoT Core. An Amazon Kinesis data stream sends the data from AWS IoT Core to the company's processing application. The processing application stores data in Amazon S3.
A new requirement states that the company also must send the raw data to a third-party system by using an HTTP API.
Which solution will meet these requirements with the LEAST amount of development work?
A solutions architect is deploying a web application that consists of a web tier, an application tier, and a database tier. The infrastructure must be highly available across two Availability Zones. The solution must minimize single points of failure and must be resilient.
Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)
After launching an instance that you intend to serve as a NAT (Network Address Translation) device in a public subnet you modify your route tables to have the
NAT device be the target of internet bound traffic of your private subnet. When you try and make an outbound connection to the internet from an instance in the private subnet, you are not successful.
Which of the following steps could resolve the issue?
Your company policies require encryption of sensitive data at rest. You are considering the possible options for protecting data while storing it at rest on an EBS data volume, attached to an EC2 instance.
Which of these options would allow you to encrypt your data at rest? (Choose three.)
