A company's new web application running on Amazon EC2 across multiple Availability Zones (AZs) will be heavily accessed during regular business hours. After business hours,usage will be minimal.

What fleet-scaling approach should be used to size the EC2 fleet to handle the traffic demands?

A web application has an increase in traffic during certain times of the day, and a solutions architect notices that CPU usage is high during those periods. Sometimes the CPU usage reaches 100%, which results in poor application performance How should the solutions architect ensure that adequate compute resources are provisioned at all times?

A customer has an application that consists oftwo layers: an ingestion layer that does some initial processing, and a second layer that does additional processing, which is much more resource intensive. The first layer consists of EC2 On-Demand Instances to ensure that all requests can be successfully received. The second layer for processing requires GPUs and uses Spot Instances.

What service should the firstlayer useto deliver job batches to the second layer?

Users submit requests to a service that takes several minutes to process. A solutions architect needs to ensure that these requests are processed at least once, and that the service has the ability to handle large increases in the number of requests.

How should these requirements be met?

A solutions architect is developing a multiple-subnet VPC architecture. The solution will consist of six subnets in two Availability Zones. The subnets are defined as public, private and dedicated for databases. Only the Amazon EC2 instances running in the private subnets should be able to access a database.

Which solution meets these requirements?

A company has an on-premises MySQL database used by the global sales team with infrequent access patterns.The sales team requires the database to have minimal downtime. A database administrator wants to migrate this database to AWS without selecting a particular instance type in anticipation of more users in the future.

Which service should a solution architect recommend?

A company maintains about 300 TB m Amazon S3 Standard storage month after month. The S3 objects are each typically around 50 GB m size and are frequently replaced with multipart uploads by their global application. The number and size of S3 objects remain constant but the company's S3 storage costs are increasing each month.

How should a solutions architect reduce costs in this situation?

A solutions architect plans to convert a company's monolithic web application into a multi-tier application. The company wants to avoid managing its own infrastructure. The minimum requirements for the web application are high availability scalability and regional low latency during peak hours. The solution should also store and retrieve data with millisecond latency using the application's API.

Which solution meets these requirements?

An administrator of a large company wants to monitor for and prevent any cryptocurrency-related attacks on the company's AWS accounts.

Which AWS service can the administrator use to protect the company against attacks?

A solutions architect is designing an VPC that requires access to a remote API server using IPv6 Resources within the VPC should not be accessed directly from the internet.

How should this be achieved?

A company needs to store data for 6 years. The company will need to have immediate and highly available access to the data at any point in time, but will not require frequent access.

What lifecycle action should be taken to meet these requirements while reducing costs?

A company has a three-tier, stateless web application. The company's web and application tiers run on Amazon BC2 instances in an Auto Scaling group with an Amazon Elastic Block Store (Amazon EBS) root volume, and the database tier runs on Amazon RDS for PostgreSQL. The company's recovery point objective (RPO) is 2 hours.

What should a solutions architect recommend to enable backups for this environment?

A company runs an application in the AWS Cloud and uses Amazon DynamoDB as1 the database. The company deploys Amazon EC2 instances to a private network to process data from the database. The company uses two NAT instances to provide connectivity to DynamoDB.The company wants to retire the NAT instances.A solutions architect must implement a solution that provides connectivity to DynamoDB and that does not require ongoing management.What is the MOST cost-effective solution that meets these requirements?

A company is running its application in a single region on Amazon EC2 with Amazon Elastic Block Store (Amazon EBS) and S3 as part of the storage design.

What should be done to reduce data transfer costs?

A company runs a legacy application with a single-tier architecture on an Amazon EC2 instance Disk I/O is low. With occasional small spikes during business hours. The company requires the instance to be stopped from 8 PM to 8 AM daily.

Which storage option is MOST appropriate for this workload?

A company is building a cloud storage and sharing application for photos. Users can upload photos from their computers and mobile phones to be stored durably in the cloud. After photos are uploaded, most are shared and downloaded frequently for the first 40-90 days. The photos are generally accessed less often after 90 days but some photos maintain a high access rate. The application initially stores photos n Amazon S3 Standard. A solutions architect needs to reduce the application's operational costs without sacrificing user experience or data durability.

Which strategy should the solutions architect use to meet these requirements MOST cost- effectively?

A solutions architect is designing a shared storage solution for a web application that is deployed across multiple Availability Zones.The web application runs on Amazon EC2 instances in an Auto Scaling group. The company anticipates making frequent changes to the content, so the solution must have strong consistency.

Which solution meets these requirements?

A company designs a mobile app for its customers to upload photos to a website. The app needs a secure login with multi-factor authentication (MFA). The company wants to limit the initial build time and the maintenance of the solution.

Which solution should a solutions architect recommend to me t these requirements?

A solutions architect is designing a solution that will include a database in Amazon RDS Corporate security policy mandates that the database its logs, and its backups are all encrypted.

What is the MOST efficient option to fulfill the security policy using Amazon RDS?

A company wants to monitor its AWS costs for financial review. The cloud operations team is designing an architecture in the AWS Organizations master account to query AWS Cost and Usage Reports for all member accounts.The team must run this query once a month and provide a detailed analysis of the bill.

Which solution is the MOST scalable and cost-effective way to meet these requirements?
