[单选题] A solutions architect is designing the storage architecture for a new web application used for stonng and viewing engineering drawings. All application components will be deployed on the AWS infrastructure. The application design must support caching to minimize the amount of time that users wait for the engineering drawings to load. The application must be able to store petabytes of data. Which combination of storage and caching should the solutions architect use?

A、 Amazon S3 with Amazon CloudFront

B、 Amazon S3 Glacier with Amazon ElastiCache

C、 Amazon Elastic Block Store (Amazon EBS) volumes with Amazon CloudFront

D、 AWS Storage Gateway with Amazon ElastiCache

[单选题] A company recently released a new type of internet-connected sensor. The company is expecting lo sell thousands of sensors, which are designed to stream high volumes of data each second to a central location. A solutions architect must design a solution that ingests and stores data so that engineering teams can analyze it in near-real time with millisecond responsiveness. Which solution should the solutions architect recommend?

A、 Use an Amazon SQS queue to ingest the data. Consume the data with an AWS Lambda function, which then stores the data in Amazon Redshift.

B、 Use an Amazon SOS queue to ingest the data. Consume the data with an AWS Lambda function, which then stores the data in Amazon DynamoDB.

C、 Use Amazon Kinesis Data Streams to ingest the data. Consume the data with an AWS Lambda function, which then stores the data in Amazon Redshift.

D、 Use Amazon Kinesis Data Streams to ingest the data. Consume the data with an AWS Lambda function, which then stores the data in Amazon DynamoDB.

[单选题] A company is using Amazon EC2 to run its big data analytics workloads. These variable workloads run each night, and it is critical they finish by the start of business the following day. A solutions architect has been tasked with designing the MOST cost-effective solution.
Which solution will accomplish this?

A、 Spot Fleet

B、 Spot Instances

C、 Reserved Instances

D、 On-Demand Instances

[单选题] A company is investigating potential solutions that would collect, process, and store users' service usage data. The business objective is to create an analytics capability that will enable the company to gather operational insights quickly using standard SQL queries. The solution should be highly available and ensure Atomicity, Consistency, Isolation, and Durability (ACID) compliance in the data tier.
Which solution should a solutions architect recommend?

A、 Use Amazon DynamoDB transactions

B、 Create an Amazon Neptune database in a Multi AZ design

C、 Use a fully managed Amazon RDS for MySQL database in a Multi-AZ design

D、 Deploy PostgreSQL on an Amazon EC2 instance that uses Amazon EBS Throuchput Optimized HDD (st1) storage.

[单选题] A company has migrated an on-premises Oracle database to an Amazon RDS (or Oracle Multi- AZ DB instance In the us-east-l Region. A solutions architect is designing a disaster recovery strategy to have the database provisioned In the us- west-2 Region In case the database becomes unavailable in the us-east-1 Region. The design must ensure the database is provisioned in the us-west-2 Region in a maximum of 2 hours, with a data loss window of no more than 3 hours.
How can these requirements be met?

A、 Edit the DB instance and create a read replica in us-west-2. Promote the read replica to master In us- west-2 in case the disaster recovery environment needs to be activated.

B、 Select the multi-Region option to provision a standby instance in us-west-2. The standby Instance will be automatically promoted to master In us-west-2 in case the disaster recovery environment needs to be created.

C、 Take automated snapshots of the database instance and copy them to us-west-2 every 3 hours. Restore the latest snapshot to provision another database instance in us-west-2 in case the disaster recovery environment needs to be activated.

D、 Create a multimaster read/write instances across multiple AWS Regions Select VPs in us-east-1 and us-west-2 lo make that deployment. Keep the master read/write instance in us-west-2 available to avoid having to activate a disaster recovery environment.

[单选题] A company has an application with a REST-based Interface that allows data to be received in near-real time from a third-party vendor. Once received, the application processes and stores the data for further analysis. The application Is running on Amazon EC2 instances. The third-party vendor has received many 503 Service Unavailable Errors when sending data to the application. When the data volume spikes, the compute capacity reaches its maximum limit and the application is unable to process
All requests. Which design should a solutions architect recommend to provide a more scalable solution?

A、 Use Amazon Kinesis Data Streams to ingest the data. Process the data using AWS Lambda functions.

B、 Use Amazon API Gateway on top of the existing application. Create a usage plan with a quota limit for the third-party vendor.

C、 Use Amazon Simple Notification Service (Amazon SNS) to ingest the data. Put the EC2 instances in an Auto Scaling group behind an Application Load Balancer.

D、 Repackage the application as a container. Deploy the application using Amazon Elastic Container Service (Amazon ECS) using the EC2 launch type with an Auto Scaling group.

[单选题] A company that develops web applications has launched hundreds of Application Load Balancers (ALBs) in multiple Regions. The company wants to create an allow list (or the IPs of all the load balancers on its firewali device. A solutions architect is looking for a one-time, highly available solution to address this request, which will also help reduce the number of Ips that need to be allowed by the firewall. What should the solutions architect recommend to meet these requirements?

A、 Create a AWS Lambda function to keep track of the IPs for all the ALBs in different Regions Keep refreshing this list.

B、 Set up a Network Load Balancer (NLB) with Elastic IPs. Register the private IPs of all the ALBs as targets to this NLB.

C、 Launch AWS Global Accelerator and create endpoints for all the Regions. Register all the ALBs in different Regions to the corresponding endpoints

D、 Set up an Amazon EC2 instance, assign an Elastic IP to this EC2 instance, and configure the instance as a proxy to forward traffic to all the ALBs.

[单选题] A company is designing a web application using AWS that processes insurance quotes Users will request quotes from the application. Quotes must be separated by quote type must be responded to within 24 hours, and must not be lost. The solution should be simple to set up and maintain.
