A solutions architect is designing a new service behind Amazon API

Gateway. The request patterns for the service will be unpredictable and

can change suddenly from 0 requests to over 500 per second.The total

size of the data that needs to be persisted in a backend database is

currently less than 1 GB with unpredictable future growth Data can be

queried using simple key-value requests. Which combination of AWS

services would meet these requirements? (Select TWO )

A solutions architect needs to design a managed storage solution for

a company's application that includes high-performance machine

learning.This application runs on AWS Fargate and the connected storage

needs to have concurrent access to files and deliver high

performance.Which storage option should the solutions architect

recommend?

A company has a multi-tier application that runs six front-end web
Servers in an Amazon EC2 Auto Scaling group in a single Availability
Zone behind an Application Load Balancer (ALB). A solutions architect
Needs to modify the infrastructure to be highly available without
Modifying the application. Which architecture should the solutions
Architect choose that provides high availability?

A company runs an internal browser-based application The application
Runs on Amazon EC2 instances behind an Application Load Balancer.The
Instances run in an Amazon EC2 Auto Scaling group across multiple
Availability Zones. The Auto Scaling group scales up to 20 instances
During work hours, but scales down to 2 instances overnight Staff are
Complaining that the application is very slow when the day begins,
Although it runs well by mid-morning.How should the scaling be changed
To address the staff complaints and keep costs to a minimum?

A solutions architect is designing a solution to access a catalog of
Images and provide users with the ability to submit requests to
Customize images.Image customization parameters will be in any request
Sent to an AWS API Gateway API. The customized image will be generated
On demand, and users will receive a link they can click to view or
Download their customized image.The solution must be highly available
For viewing and customizing images What is the MOST cost-effective
Solution to meet these requirements?

A bicycle sharing company is developing a multi-tier architecture to
Track the location of its bicycles during peak operating hours.The
Company wants to use these data points in its existing analytics
Platform A solutions architect must determine the most viable multi-tier
Option to support this architecture. The data points must be accessible
From the REST API. Which action meets these requirements for storing and
Retrieving location data?

A solutions architect is deploying a distributed database on
Multiple Amazon EC2 instances. The database stores all data on multiple
Instances so it can withstand the loss of an instance. The database
Requires block storage with latency and throughput to support several
Million transactions per second per server.Which storage solution should
The solutions architect use?

A solutions architect needs to ensure that API calls to Amazon
DynamoDB from Amazon EC2 instances in a VPC do not traverse the
Internet.What should the solutions architect do to accomplish this?
(Select TWO )

A solutions architect is designing a web application that will run
On Amazon EC2 instances behind an Application Load Balancer (ALB).The
Company strictly requires that the application be resilient against
Malicious internet activity and attacks, and protect against new common
Vulnerabilities and exposures.What should the solutions architect
Recommend?

A company has been storing analytics data in an Amazon RDS instance
For the past few years. The company asked a solutions architect to find
A solution that allows users to access this data using an API.The
Expectation is that the application will experience periods of
Inactivity but could receive bursts of traffic within seconds.Which
Solution should the solutions architect suggest?

A company's web application is using multiple Linux Amazon EC2
Instances and storing data on Amazon EBS volumes.The company is looking
For a solution to increase the resiliency of the application in case of
A failure and to provide storage that complies with atomicity,
Consistency, isolation, and durability (ACID).What should a solutions
Architect do to meet these requirements?

A company has an application that calls AWS Lambda functions. A
Recent code review found database credentials stored in the source code.
The database credentials need to be removed from the Lambda source code.
The credentials must then be securely stored and rotated on an ongoing
Basis to meet security policy requirements.What should a solutions
Architect recommend to meet these requirements?

A solutions architect needs the static website within an Amazon S3
Bucket. A solutions architect needs to ensure that data can be recovered
In case of accidental deletion.Which action will accomplish this?

A company is managing health records on-premises.The company must
Keep these records indefinitely, disable any modifications to the
Records once they are stored, and granularly audit access at all levels.
The chief technology officer (CTO) is concerned because there are
Already millions of records not being used by any application, and the
Current infrastructure is running out of space. The CTO has requested a
Solutions architect design a solution to move existing data and support
Future records.Which services can the solutions architect recommend to
Meet these requirements'?

A company currently operates a web application backed by an Amazon
RDS MySQL database. It has automated backups that are run daily and are
Not encrypted. A security audit requires future backups to be encrypted
And the unencrypted backups to be destroyed.The company will make at
Least one encrypted backup before destroying the old backups What should
Be done to enable encryption for future backups?

A client reports that they want see an audit log of any changes
Made to AWS resources in their account.What can the client do to achieve
This?

An application running in a private subnet accesses an Amazon
DynamoDB table. There is a security requirement that the data never
Leave the AWS network.How should this requirement be met?

A three-tier application is being created to host small news
Articles. The application is expected to serve millions of users. When
Breaking news occurs, the site must handle very large spikes in traffic
Without significantly impacting database performance.Which design meets
These requirements while minimizing costs?

During a review of business applications, a Solutions Architect
Identifies a critical application with a relational database that was
Built by a business user and is running on the user's desktop. To reduce
The risk of a business interruption, the Solutions Architect wants to

A company has thousands of files stored in an Amazon S3 bucket that
Has a well-defined access pattern. The files are accessed by an
Application multiple times a day for the first 30 days. Files are rarely
Accessed within the next 90 days. After that, the files are never
Accessed again. During the first 120 days, accessing these files should
Never take more than a few seconds.Which lifecycle policy should be used
For the S3 objects to minimize costs based on the access pattern?
